The Arlington Municipal Airport is the owner of the building and improvements formerly occupied by the Point Church located at 18722 59th Ave. NE, Arlington. The City believes substantial improvements will be required soon, so City staff has recommended the building(s) be declared as surplus, and that the most economical approach is to sell the building(s) in their present condition to a private buyer willing to improve the building(s). Pursuant to AMC 3.70.020, the buildings may be disposed of pursuant to a Request for Proposal (RFP) process. Discussion followed with Mr. Ryan answering Council questions.
Amendment No. 1 to the 169th St NE Connecting Segment Design Contract with SCJ
Alliance Public Works Director Jim Kelly reviewed Amendment No. 1 for the 169th Street Connecting Segment 30-100% design. The City has been working on the development of an integrated multi-modal transportation system in the Smokey Point neighborhood that is connected to the Cascade Industrial Center; part of this network is the completion of 169th Street. The proposed 169th St Connecting Segment project includes a two-lane roadway, multiuse path, sidewalks, and drainage improvements. Completion of this final segment of 169th St will support the continued growth of the CIC and jobs while improving walkability and multimodal transportation within Smokey Point. The City contracted with SCJ in April 2022 for preliminary design up to 30% drawings. The project is now ready for design up to 100%. In early 2023 the City received a FHWA Congressionally Directed Spending grant in the amount of $3,654,893.00 completing the funding package for this project. Staff has negotiated the scope and is recommending award of Amendment No. 1 for 30-100% design documents to SCJ Alliance per the attached negotiated scope of work. Discussion followed with Mr. Kelly answering Council questions.
Ordinance Amending Arlington Municipal Code (AMC) Title 13 Water and Sewer Planning Manager Amy Rusko reviewed an ordinance to amend Arlington Municipal Code Title 13 Water and Sewers. The proposed amendment to AMC Title 13 Water and Sewers is a City-initiated request to revise the sections of AMC Chapters 13.04, 13.08, and 13.12. The amendment provides updated regulations regarding utilities provided for accessory dwelling units. The revisions include definitions, housing type classifications, residential classifications, water and sewer connections, connection charges, and water/sewer/stormwater rates. The AMC Title 13 Code Amendments were proposed with the 2023 Docket. The proposed code amendments are required to be updated to include accessory dwelling unit connection standards. Discussion followed with Ms. Rusko answering Council questions.
Ordinance Amending Arlington Municipal Code Chapter 20.44 Supplemental Uses Planning Manager Amy Rusko reviewed an ordinance to amend Arlington Municipal Code (AMC) Chapter 20.44 Supplemental Uses. The amendment to AMC Chapter 20.44 Supplemental Uses is a City-initiated request to update Section 20.44.032 – Master Planned Neighborhoods and Section 20.44.042 – Accessory Dwelling Units.
Minutes of the City of Arlington City Council Workshop November 13, 2023
Page 3 of 4
Section 20.44.032 amends the procedure and requirements for parcels within the Master Plan Neighborhood Overlay of the city. The update amends the title of the section to Subarea Plans and establishes criteria and procedures for both private and public initiated subarea plans. The subarea plans correlate to the fourteen subareas of the City’s Comprehensive Plan that distinguish specific geographical areas and existing neighborhoods within the community. The intent of creating subareas is to develop a subarea plan for each area of the city that contains specific policies and criteria to guide land development, incorporate missing middle housing options, transportation facilities, community facilities, infrastructure and capital improvement decisions that provide for a more coordinated, efficient, and effective structure for predictable neighborhood planning.
Section 20.44.042 amends the requirements and criteria set forth for Accessory Dwelling Units per Engrossed House Bill 1337 as filed to the Secretary of State of the State of Washington on May 10, 2023. The amendments follow the criteria adopted by the State of Washington and all updates to RCW 36.70A, RCW 43.21C, and RCW 64.32, 64.34, 64.38, 64.90. The AMC Chapter 20.44 Zoning Code Amendments were proposed with the 2023 Docket. The proposed zoning code amendments are required to establish subarea planning in the city and to meet the accessory dwelling unit requirements from the state.

Exhibit A - Scope of Work, Amendment No. 1 Page 2 of 11
General Assumptions
The following assumptions apply to this scope of work. Assumptions that apply primarily to individual phases of work are included with
the respective scopes for each phase.
1. All prior work on Phases 1-3 for the 30% design is complete and no changes are made.
2. Submittals will be made at the 60%, 90%, 100% and Ad-Ready milestones. The following submittal guidelines apply:
a. The 60% design shall locate major design features, design the project footprint, and develop the estimate of cost.
b. The 90% submittal shall represent a complete, construction-ready design so that the CITY can review the full design.
c. The 100% submittal shall be a response to 90% comments rather than advancement of design.
d. The ready-for-construction package is a check print set to confirm that all the responses to the 90% were satisfactorily
resolved.
3. This amendment adds an additional ten (10) months to the duration of the project.
4. The 30% design includes two 2 travel lanes, a 12-foot-wide shared use path with a 3-foot-wide landscaping area on the north
side of the road, and a 5-foot-wide sidewalk on the south side of the road. The project will include stormwater conveyance and
detention, illumination, 2 new Rectangular Rapid-Flashing Beacon (RRFB) pedestrian crossings, and an intersection at the future
40th street connection.
5. The 30% Plans have been accepted by the CITY and represent the preliminary design to be advanced. Adjustments to the profile
and layout of ponds will be included to minimize earthwork, minimize wetland impacts, and improve permitting conditions.
6. The project is required to tie-in to the new multi-use path along the north side of 168th St NE that was recently constructed by
Amazon. This requires a design update to the 30% preliminary design for this facility to be on the north side of 169th St NE.
7. The CITY contracted separately to have Soundview perform a wetland delineation survey which was provided to the
CONSULTANT in AutoCAD.
8. In providing opinions of cost and schedules for the project, the CONSULTANT will have no control over cost or price of labor and
materials; unknown or latent conditions of existing equipment or structures that might affect operation or maintenance costs;
competitive bidding procedures and market conditions; time or quality of performance by operating personnel or third parties;
and other economic and operational factors that might materially affect the ultimate project cost or schedule. The
CONSULTANT, therefore, will not warranty that the actual project costs, financial aspects, economic feasibility, or schedules will
not vary from the CONSULTANT’s opinions, analyses, projections, or estimates.
9. The CITY is contracting separately with third party consultants to perform survey, geotechnical and environmental work related
to this project with whom the CONSULTANT will need to coordination throughout the execution of this project.
10. The scope does not include utility potholing. If required, this work can be added by amendment.
11. The CITY will provide right of entries for all necessary private-property access.
12. This scope does not include right of way negotiation or acquisition.
13. CITY reviews will take 3-weeks and comments will be resolved of conflicts prior to sending them to the CONSULTANT.
14. Right of way plans will conform to the WSDOT/LAG Manual requirements for federally funded projects.

NOW, THEREFORE, the City Council of the City of Arlington does hereby ordain as follows:
Section 1. Arlington Municipal Code section 20.44 shall be and hereby is amended to
read as follows:
20.44.032 Subarea Plans
(a) The Comprehensive Plan designates fourteen subareas that distinguish specific
geographical areas and existing neighborhoods within the community. The intent
of creating subareas is to develop a subarea plan for each area of the city that
ORDINANCE NO. 2023-XXX 2
contains specific policies and criteria to guide land development, incorporate
missing middle housing options, transportation facilities, community facilities,
infrastructure and capital improvement decisions that provide for a more
coordinated, efficient, and effective structure for predictable neighborhood
planning. The subarea plans encompass both newly created subareas and those
that work with existing neighborhoods to provide criteria for infill and
redevelopment purposes.
(b) The subarea plans are to be produced by the city, with the exception of two areas
designated on the City’s Zoning Map and Future Land Use Map with the Master
Planned Neighborhood (MPN) Overlay. These two areas are known as East Hill and
Lindsay Annexation (portion of Hilltop). The list of subareas is listed below:
(1) Arlington Terrace
(2) Cascade Industrial Center
(3) Crown Ridge
(4) East Hill
(5) Edgecomb
(6) Gateway
(7) Gleneagle
(8) Haller City
(9) Hilltop
(10) Island Crossing
(11) Kent Prairie
(12) Old Town
(13) Smokey Point
(14) West Bluff
(c) A subarea plan is typically developed to encompass the entire subarea, however
under certain circumstances it may be developed to include only specific
neighborhoods, corridors, downtown, or other types of special districts that show
cohesive characteristics. The East Hill and Lindsay Annexation subareas shall be
developed in their entirety.
(d) As subarea plans are created, elements of form based code are proposed to be
included to provide the community with a predictable design and development
pattern that is customized for the specific area.
(e) Subarea plans are to be processed in conjunction with a Planned Action
Environmental Impact Statement (EIS). A planned action is a development project
whose impacts have been identified and addressed through an EIS associated with
the subarea plan for the specific geographical area before individual projects are
proposed. A planned action involves detailed State Environmental Policy Act
(SEPA) review and preparation of EIS documents in conjunction with subarea
plans, consistent with RCW 43.21C.031 and WAC 197-11-164 through WAC 197-
ORDINANCE NO. 2023-XXX 3
11-172. The up front analysis of impacts and mitigation measures then facilitates
environmental review of subsequent individual development projects.
(f) A subarea plan application under the Master Planned Neighborhood (MPN)
Overlay shall include the following information:
(1) A land use application and submittal checklist with all required documents.
(2) Permit fee, as shown on the most current fee schedule.
(3) The subarea plan shall include the following elements:
i. One element shall be small lot detached single-family residential or
cottage housing, with a minimum lot size of 3,600 square feet and a maximum of
4,500 square feet and consisting of seventy (70) percent of the total lots.
ii. Second element shall be attached residential, such as townhomes, row
houses, or duplexes, and shall be developed as fee simple lots through a unit lot
subdivision (subject to §20.44.020 Unit Lot Subdivisions) and consisting of twenty
(20) percent of the total lots.
iii. Third element shall be one of the below options and shall consist of ten
(10) percent of the total lots.
(A) Accessory Dwelling Unit (constructed with residence)
(B) Mixed-Use Development (vertical)
(C) Multi-Family Apartments
(D) Multi-Family Fourplex
(E) Multi-Family Garden Apartments
(F) Small Commercial
iv. Fourth element shall be the location of Recreational Facilities, Open
Space, and Trail System that consists of ten (10) percent of the total area of land,
minus areas to be preserved as Native Growth Protection Areas (NGPA).
(A) This designation shall include areas proposed to be dedicated
to the city as public spaces. All dedicated parks shall be a minimum of two (2) acres
in size and coordinated with the city prior to approval.
(B) The trail system shall consist of a paved trail that connects the
required sidewalk system and to all recreation facilities and open spaces.
(4) The subarea plan shall show the location of each housing type listed above in
the way of a subdivision layout.
(5) The architectural design of the structures shall comply with the Development
Design Standards pursuant to §20.46 Design.
(6) The subarea plan shall show the conceptual infrastructure plans that include
location, types, and sizes of streets, sewer, water, stormwater, etc.
(7) Public infrastructure impacts and financing strategies including any
improvements to existing on or off-site facilities necessary to support the
proposed subarea plan.

proposed subarea plan. The analysis shall also include all current and future
designated multi-model plans.
(9) The subarea plan shall adhere to the Arlington Complete Streets Program.
(10) The subarea plan shall provide anticipated phasing or sector lines on the
subarea map.
(g) The subarea plan for the East Hill and Lindsay Annexation area serves as the typical
preliminary plat document for development and shall follow the process of a
conditional use permit (§20.16.225 Special Use Permits and Conditional Use
Permits).
(h) The subarea plan is subject to a Public Hearing before the Hearing Examiner and
shall follow the hearing procedures of §20.24 (Hearing and Pre-Hearing
Procedures and Appeals and Applications).
(i) In approving a subarea plan, the city may require the plan to comply with site
specific development regulations that the city deems appropriate and approved
by the hearing examiner.
(j) The approved subarea plan is required to be recorded with the Snohomish County
Auditor Office.
(k) After recording, subsequent land use permits (final plats or unit lot subdivisions),
civil permits, and building permits are required to be submitted and approved
prior to development on any lots. Procedures for these permits are found in the
Arlington Municipal Code.

E. REGULATORY REQUIREMENTS, FINDINGS, AND CONCLUSIONS 1. SEPA COMPLIANCE:
Type of Determination Issued Date Distribution and Public Notice
SEPA Determination on Non-Significance (DNS) 8/30/2023 City Public Notice Website Emailed to Review Agencies Posted at City Hall, Arlington Library, Smokey Point Post Office The Herald Published Date – 9/1/2023 Comment Period – 9/1/2023 to 9/15/2023 Public comments received during the public comment period.
Comment Summary City Response The Tulalip Tribes provided comments concerning the potential impacts the proposed increased density could have on adjacent critical areas.
9/06/2023
The increase in density is required per the population allocation that was received by the city. The subarea standards would ensure for more compact building areas that would leave space for critical areas in the Master Planned Neighborhood Overlay zones. ADU requirements were produced by the State to follow. The City is still required to comply with the Critical Area Ordinance and Department of Ecology regulations.
Master Builders Assoc. provided comments requesting removal of the proposed ADU utility connection requirements if a property is converted into a condominium and removal of the 60% AMI restriction on the sale of a condominium unit.
9/15/2023
Staff does not believe the city is in violation of 64.34.050(1) for the utility connection requirement. Utilities are governed by the City of Arlington Public Works Department. Other detached or attached residential units that are comparable to ADUs (single family, duplexes, and townhouse) are required to have separate water and sewer connections to each unit. An ADU would not be treated any differently. The exception is that if the ADU is owned by the same owner as the primary residence then the city is willing to allow for flexibility. Staff concurred that the 60% AMI requirement cannot be tied to the conveyance of a condominium unit. Staff has updated the code amendments based on the guidance from the Department of Commerce and ordinance from other cities in the state that have recently passed updated ADU codes. 2.

Policy Countywide Planning Policy Description
CPP-HO-2
County and city comprehensive plans shall include policies to meet affordable housing goals consistent with VISION 2050. Jurisdictions should demonstrate within their land use and housing elements that they can accommodate needed housing consistent with the Regional Growth Strategy and Snohomish County Growth Targets. These efforts should include facilitating the regional fair share of affordable housing for very low, low, moderate, and middle-income households and special needs individuals. Housing elements of comprehensive plans shall be periodically evaluated for success in facilitating needed housing.
CPP-HO-3 The county and cities should participate in multi-jurisdictional affordable housing programs and engage in other cooperative efforts to promote and contribute to an adequate supply of affordable, special needs, and diverse housing countywide.
CPP-HO-4 density housing to help meet future housing needs, diversify the housing stock, and provide more affordable home ownership and rental opportunities. This approach should include code updates to ensure that zoning designations and allowed densities, housing capacity, and other restrictions do not preclude development of moderate density housing.
CPP-HO-9 In order to improve the jobs-to-housing balance in Snohomish County, jurisdictions shall adopt comprehensive plans that provide for the development of: a. A variety of housing choices, including affordable housing, so that workers at all income levels may choose to live in proximity to existing and planned employment concentrations and transit service; and b. Employment opportunities in proximity to existing and planned residential communities.
CPP-HO-10 Jurisdictions should encourage the use of environmentally sensitive housing development practices and environmentally sustainable building techniques and materials in order to minimize the impacts of growth and development on the county's natural resource systems. This approach should also consider the potential costs and benefits to site development, construction, and building maintenance to balance housing affordability and environmental sustainability.
CPP-HO-14 The county and cities should incentivize and promote the development and preservation of long-term affordable housing through the use of zoning, taxation, and other tools, including height or density bonuses, property tax incentives and parking requirement reductions. The incentives should apply where feasible to encourage affordable housing.
Policy Multicounty Planning Policy Description MPP-DP-1 Develop high-quality, compact urban communities throughout the region’s urban growth area that impart a sense of place, preserve local character, provide for mixed uses and choices in housing types, and encourage walking, bicycling, and transit use. MPP-DP-2 Reduce disparities in access to opportunity for the region’s residents through inclusive community planning and targeted public and private investments that meet the needs of current and future residents and businesses. MPP-DP-3 Enhance existing neighborhoods to provide a high degree of connectivity in the street network to accommodate walking, bicycling, and transit use, and sufficient public spaces. MPP-H-1 Plan for housing supply, forms, and densities to meet the region’s current and projected needs consistent with the Regional Growth Strategy and to make significant progress towards jobs/ housing balance.

20.44.032 Master Planned Neighborhood Development (MPND).
(a) In any Master Planned Neighborhood district (§20.36.054, Master Planned
Neighborhood Overlay District Established) no development may be permitted until the
developer has prepared and received approval of a master plan for the entire area
included in the MPN district.
(b) Since the approval of a master plan affects the zoning, and thus use of the property, said master plan shall be processed as an amendment to this Title (Chapter 20.96). (c) No area of less than twenty contiguous acres may be planned through a MPN approval process, and then only (i) upon the request of the owner or majority of owners of all the property intended to be covered by such an overlay zone, or (ii) by the City Council in implementing the MPN land use designation pursuant to subsection (d). Approval of MPNs is achieved through a rezone process. (d) The MPN district shall be used on any land with a Master Planned Neighborhood land use designation as shown on the Comprehensive Plan Land Use Map. If property is placed in an MPN district by the Council prior to a master plan being developed (§20.44.032 (Master Planned Neighborhood Developments), it shall not show the individual elements until the master plan is approved. (e) For areas designated Master Planned Neighborhood in the Comprehensive Plan, MPND approval may be sought prior to or after annexation to the City. However, in the case where MPND approval is not approved prior to or concurrent with annexation the entire annexation area shall be zoned Suburban Residential until such time that an MPND is approved. (f) At a minimum the master plan shall identify:
(1) The locations and sizes of the districts as follows: (i) One element of each MPN district shall be the low-density residential element. Here there is one possibility, using the Residential Ultra Low Capacity district described in §20.36.010 (Residential Districts Established). Within that portion of the MPN zone that is developed for low-density residential purposes, all development must be in accordance with the regulations applicable to the Residential Ultra Low Capacity district. Within any MPND, not less than fifty percent of the total area may be developed for lower density residential (Residential Ultra Low Capacity) purposes. (ii) A second element of each MPN district may be the medium to higher density residential element. Here there are four possibilities, each one corresponding either to the Residential Low Capacity, the Residential Moderate Capacity, Residential Medium, or the Residential High-Capacity zoning districts described in Subsection 20.36.010 (Residential Districts Established). Within that portion of the MPN district that is developed for medium or higher density residential purposes, all development must be in accordance with the regulations applicable to the residential district to which the particular MPN zoning district corresponds. (iii) A third element of each MPN district may be the commercial element. Here there is one possibility, corresponding to the Neighborhood Commercial district identified in §20.36.020 (Commercial Districts Established). Within that portion of a MPN district that is developed for purposes permissible in a NC district, all development must be in accordance with the regulations applicable to the NC district. (iv) A public services/facilities element may be a fourth element of any MPN district. Here uses permitted within the Public/Semi-Public district would be permitted within the MPN district. If a P/SP element is included, then within that portion of the MPN district that is developed for purposes permissible in a P/SP district, all development must be in accordance with the regulations applicable to the P/SP district. (2) The approximate locations, types, and sizes of public facilities and amenity areas
(e.g., parks, schools, open space, common landscaped areas, etc.); (3) Conceptual infrastructure plans (e.g., location, types, and sizes of streets, sewer, water, stormwater, etc.); (4) Compliance with those portions of the City’s Development Design Standards having to do with neighborhood design pursuant to Chapter 20.46, Design; (5) Public infrastructure financing strategies (including any improvements to existing on- or off-site facilities necessary to support the MPND); and (6) An anticipated phasing and/or build out schedule, subject to an analysis of service capacity by the City. (g) Unless the City’s SEPA Responsible Official determines otherwise, the applicant shall develop a programmatic Environmental Impact Statement for the MPN permit. Subsequent development permits may then rely on this EIS to the extent feasible to minimize additional SEPA review. It shall be the intent of the City that during subsequent permitting no additional SEPA review would be required for any action or impact analyzed in the programmatic EIS, unless unforeseen or extraordinary environmental issues arise. (h) In a Master Planned Neighborhood Development, once the master plan is approved and zoning districts assigned per (f)(1), the developer may make use of the land for any purpose authorized in those particular districts, subject to the provisions of the master plan and this title. (i) In those areas of the MPND assigned to the Residential Ultra Low Capacity, lots adjacent to critical areas may be reduced in size and width to a minimum of six thousand square feet and a width of sixty feet so long as the standard of §20.48.030(a) (Lot Shape and Minimum Lot Widths) is met and so long as a gross density of four dwelling units per acre is not exceeded. (j) As indicated in the Tables of Permissible Uses a Master Planned Neighborhood
Development is the only permissible use of a MPN district, and Master Planned Neighborhoods are permissible only in such zones. (k) In approving the MPND the Council may require that the MPND comply with any site-specific development regulations that the City may develop.
20.44.032 Subarea Plans
(a) The Comprehensive Plan designates fourteen subareas that distinguish specific geographical areas
and existing neighborhoods within the community. The intent of creating subareas is to develop a
subarea plan for each area of the city that contains specific policies and criteria to guide land
development, incorporate missing middle housing options, transportation facilities, community
facilities, infrastructure and capital improvement decisions that provide for a more coordinated,
efficient, and effective structure for predictable neighborhood planning. The subarea plans
encompass both newly created subareas and those that work with existing neighborhoods to provide
criteria for infill and redevelopment purposes.
(b) The subarea plans are to be produced by the city, with the exception of two areas designated on the
City’s Zoning Map and Future Land Use Map with the Master Planned Neighborhood (MPN)
Overlay. These two areas are known as East Hill and Lindsay Annexation (portion of Hilltop). The
list of subareas is listed below:
(1) Arlington Terrace
(2) Cascade Industrial Center
(3) Crown Ridge
(4) East Hill
(5) Edgecomb
(6) Gateway
(7) Gleneagle
(8) Haller City
(9) Hilltop
(10) Island Crossing
(11) Kent Prairie
(12) Old Town
(13) Smokey Point
(14) West Bluff
(c) A subarea plan is typically developed to encompass the entire subarea, however under certain
circumstances it may be developed to include only specific neighborhoods, corridors, downtown,
or other types of special districts that show cohesive characteristics. The East Hill and Lindsay
Annexation subareas shall be developed in their entirety.
(d) As subarea plans are created, elements of form based code are proposed to be included to provide
the community with a predictable design and development pattern that is customized for the
specific area.
(e) Subarea plans are to be processed in conjunction with a Planned Action Environmental Impact
Statement (EIS). A planned action is a development project whose impacts have been identified
and addressed through an EIS associated with the subarea plan for the specific geographical area
before individual projects are proposed. A planned action involves detailed State Environmental
Policy Act (SEPA) review and preparation of EIS documents in conjunction with subarea plans,
consistent with RCW 43.21C.031 and WAC 197-11-164 through WAC 197-11-172. The up front
analysis of impacts and mitigation measures then facilitates environmental review of subsequent
individual development projects.
(f) A subarea plan application under the Master Planned Neighborhood (MPN) Overlay shall include
the following information:
(1) A land use application and submittal checklist with all required documents.
(2) Permit fee, as shown on the most current fee schedule.
(3) The subarea plan shall include the following elements:
i. One element shall be small lot detached single-family residential or cottage
housing, with a minimum lot size of 3,600 square feet and a maximum of 4,500
square feet and consists of seventy (70) percent of the total lots.
ii. Second element shall be attached residential, such as townhomes, row houses, or
duplexes, and shall be developed as fee simple lots through a unit lot subdivision
(subject to §20.44.020 Unit Lot Subdivisions) and consists of twenty (20) percent
of the total lots.
iii. Third element shall be one of the below options and consist of ten (10) percent of
the total lots.
(A) Accessory Dwelling Unit (constructed with residence)
(B) Mixed-Use Development (vertical)
(C) Multi-Family Apartments
(D) Multi-Family Fourplex
(E) Multi-Family Garden Apartments
(F) Small Commercial
iv. Forth element shall be the location of Recreational Facilities, Open Space, and
Trail System that consists of ten (10) percent of the total area of land, minus areas
to be preserved as Native Growth Protection Areas (NGPA).
(A) This designation shall include areas proposed to be dedicated to the city as
public spaces. All dedicated parks shall be a minimum of two (2) acres in
size and coordinated with the city prior to approval.
(B) The trail system shall consist of a paved trail that connects the required
sidewalk system and to all recreation facilities and open spaces.
(4) The subarea plan shall show the location of each housing type listed above in the way of a
subdivision layout.
(5) The architectural design of the structures shall comply with the Development Design
Standards pursuant to §20.46 Design.
(6) The subarea plan shall show the conceptual infrastructure plans that include location, types,
and sizes of streets, sewer, water, stormwater, etc.
(7) Public infrastructure impacts and financing strategies including any improvements to
existing on or off-site facilities necessary to support the proposed subarea plan.
(8) Transportation impact analysis and financing strategies including any improvements to
existing on or off-site facilities necessary to support the proposed subarea plan. The
analysis shall also include all current and future designated multi-model plans.
(9) The subarea plan shall adhere to the Arlington Complete Streets Program.
(10) The subarea plan shall provide anticipated phasing or sector lines on the subarea map.
(g) The subarea plan for the East Hill and Lindsay Annexation area serves as the typical preliminary
plat document for development and shall follow the process of a conditional use permit (§20.16.225
Special Use Permits and Conditional Use Permits).
(h) The subarea plan is subject to a Public Hearing before the Hearing Examiner and shall follow the
hearing procedures of §20.24 (Hearing and Pre-Hearing Procedures and Appeals and Applications).
(i) In approving a subarea plan, the city may require the plan to comply with site specific development
regulations that the city deems appropriate and approved by the hearing examiner.
(j) The approved subarea plan is required to be recorded with the Snohomish County Auditor Office.
(k) After recording, subsequent land use permits (final plats or unit lot subdivisions), civil permits, and
building permits are required to be submitted and approved prior to development on any lots.
Procedures for these permits are found in the Arlington Municipal Code.
20.44.042 Accessory Dwelling Units (ADU).
(a) An ADU may be either attached or detached to a primary residence.
(b) Only one detached ADU per single-family residence is allowed.

Any necessary fire egress stairs shall be located so that they are not visible from the street. (j) The required off-street parking shall be located to avoid negative impacts to neighbors and community character. (k) The required off-street parking is exempt if the ADU is located within a quarter mile of a major transit center.
(a) An ADU is defined as a residential living unit providing independent living facilities and
permanent provisions for sleeping, cooking, sanitation, and living on the same lot as a
single-family home, duplex, triplex, townhome, or other housing unit. An attached ADU
is a dwelling unit located within or attached to another housing unit. A detached ADU is
separate and detached from the primary housing unit.
(b) All ADUs require the property owner to apply for building permit in order to ensure that
the structure meets the requirements of the Arlington Municipal Code and the International
Residential Code.
(c) An ADU is required to meet the following criteria and be in compliance with RCW

exceed the allowable height for the zone and shall not be greater than the principal
residence on the property.
(7) The ADU setback requirements shall meet the density and dimensional standards
of the underlying zoning of the property and be in compliance with AMC Chapter
20.48, except ADUs abutting and served by an alley are allowed a zero lot line
setback.
(8) An ADU is required to meet any governing documents associated with the
protection of public health and safety, ground and surface waters, and critical
areas.

Arlington Planning Commission
110 E 3rd Street
Arlington, WA 98223
RE: Accessory Dwelling Units
Dear Planning Commission:
The Master Builders Association of King and Snohomish Counties takes pride in
building communities. Our 2,600 members are professional homebuilders,
architects, remodelers, tradespeople, planners and engineers, suppliers,
manufacturers, and sales and marketing professionals in your community. We are
committed to ensuring that all people can attain housing and have a safe and
healthy place to call home.
MBAKS would like to thank and express gratitude to the Planning Commission
and City Staff for their commendable efforts in updating the city's Accessory
Dwelling Unit (ADU) code. The proposed amendments to reduce barriers and
increase flexibility for ADU construction are a significant step forward in meeting
the housing needs of the city and complying with state legislation. MBAKS
supports nearly all of the proposed amendments.
ADUs, both attached and detached, have emerged as highly sought-after housing
choices, offering numerous benefits to the community. MBAKS supports most of
the proposed amendments, as ADUs have proven to be instrumental in numerous
ways:
1. Enhancing Housing Accessibility: ADUs can be used as a means for
homeowners to generate supplemental income, making homeownership more
attainable and helping them offset the costs of living in an increasingly expensive
housing market. ADUs also facilitate homeownership for younger buyers by
providing more attainable housing options, helping them qualify for their first
home. Additionally, ADUs enable seniors to age in place while offering options for
multigenerational living, fostering stronger community bonds.
2. Sustainable and Environmentally Friendly Housing: ADUs are an eco-friendly
housing option, promoting efficient land use by utilizing existing infrastructure and
underutilized spaces. Often new construction is more energy efficient overall.
They align with the city's vision of sustainable urban growth, contributing to a more
environmentally conscious future.
3. Encouraging Community Diversity: By encouraging the construction of ADUs,
Arlington is facilitating the development of a more diverse and inclusive
community. Residents of various backgrounds, income levels, and ages can
coexist in closer proximity, fostering a richer social fabric.
MBAKS specifically applauds the inclusion of beneficial changes in the updated
code, which will provide more flexibility and opportunities for attainable housing in
Arlington. These amendments, such as allowing larger ADUs, potentially
permitting two ADUs on a lot, removing owner-occupancy requirements, reducing
parking requirements, design standards, and setbacks, and allowing for ownership segregation
(condominiums), are crucial steps in addressing the housing shortfall in the city.
However, MBAKS first urges partial amendment and removal of the new water and
wastewater connections requirement if a condominium is sold. As you may know, a
condominium interest agreement governs the payment of utilities and the maintenance of the
grounds. Requiring the removal of the current meter and installation of a new meter and connections
for water and wastewater is redundant and injects the city into a private agreement. Moreover, it
increases the overall price of housing and does not allow for the free flow of property as the price is
now distorted by this requirement. Placing this restriction on condominiums may remove the ability to
redevelop or add on ADUs in Arlington. This shift is also not in alignment with state legislation and
upcoming Comprehensive Plan requirements. This change removes essential flexibility for
homeowners and homebuilders to feasibly add much needed more attainable housing options and
limits financial and funding opportunities for current and prospective residents of the city. Finally, this
provision may violate 64.34.050(1) which states:
A zoning, subdivision, building code, or other real property law, ordinance, or regulation may not
prohibit the condominium form of ownership or impose any requirement upon a condominium
which it would not impose upon a physically identical development under a different form of
ownership.
MBAKS urges the removal of a 60% AMI restriction on the sale of condominiums. The
affordability designation is not required in HB 1337 and may in fact, be unnecessary (see Terner
Center report below). Moreover, the section is unclear whether the buyer of the unit or the ultimate
occupant of the unit must be at a 60% AMI level. Next, this section would be nearly impossible for
the city to police. A prohibition on sale or the implicit controlling of the price of the unit could be
construed as rent control or at the very least interference with the free market for real estate. It also
runs counter to the objectives of HB 1337 by restricting the overall supply of housing and RCW
64.34.050(1).
ADUs are an important housing choice that fits into our existing communities and neighborhoods
while providing a more affordable and attainable housing option. A Terner Center report out of UC
Berkeley found that 58% of ADUs studied were rented for below-market-rate rent and 17% of
homeowners allowed friends and family members to stay in their ADU for free. ADUs are critical
tools for accommodating growth in the very places where many families want to live—near job
centers, existing infrastructure (like transit), and other desirable amenities.
Arlington's housing needs are evident and as the city plans for the future, ADUs can play a vital role
in accommodating growth and meeting the housing demands. Under the VISION 2050 Regional
Growth Strategy, Arlington is expected to plan for a share of the projected growth of the county
population by 2050. The updated ADU code is an initiative-taking approach toward achieving growth
targets.
In closing, the City of Arlington has a unique opportunity to lead by example and become a model for
other cities and communities in Washington. By embracing ADUs, Arlington can foster a more
inclusive, sustainable, and economically vibrant community for the benefit of all residents. MBAKS
appreciates the opportunity to comment on these necessary changes to ADUs in Arlington and we
look forward to continued collaboration on housing opportunities with the city.
Thank you for your consideration. I am happy to answer any questions you may have.
Sincerely,
Russell Joe

20.44.032 Master Planned Neighborhood Development (MPND).
(a) In any Master Planned Neighborhood district (§20.36.054, Master Planned
Neighborhood Overlay District Established) no development may be permitted until the
developer has prepared and received approval of a master plan for the entire area
included in the MPN district.
(b) Since the approval of a master plan affects the zoning, and thus use of the property, said master plan shall be processed as an amendment to this Title (Chapter 20.96). (c) No area of less than twenty contiguous acres may be planned through a MPN approval process, and then only (i) upon the request of the owner or majority of owners of all the property intended to be covered by such an overlay zone, or (ii) by the City Council in implementing the MPN land use designation pursuant to subsection (d). Approval of MPNs is achieved through a rezone process. (d) The MPN district shall be used on any land with a Master Planned Neighborhood land use designation as shown on the Comprehensive Plan Land Use Map. If property is placed in an MPN district by the Council prior to a master plan being developed (§20.44.032 (Master Planned Neighborhood Developments), it shall not show the individual elements until the master plan is approved. (e) For areas designated Master Planned Neighborhood in the Comprehensive Plan, MPND approval may be sought prior to or after annexation to the City. However, in the case where MPND approval is not approved prior to or concurrent with annexation the entire annexation area shall be zoned Suburban Residential until such time that an MPND is approved. (f) At a minimum the master plan shall identify:
(1) The locations and sizes of the districts as follows: (i) One element of each MPN district shall be the low-density residential element. Here there is one possibility, using the Residential Ultra Low Capacity district described in §20.36.010 (Residential Districts Established). Within that portion of the MPN zone that is developed for low-density residential purposes, all development must be in accordance with the regulations applicable to the Residential Ultra Low Capacity district. Within any MPND, not less than fifty percent of the total area may be developed for lower density residential (Residential Ultra Low Capacity) purposes. (ii) A second element of each MPN district may be the medium to higher density residential element. Here there are four possibilities, each one corresponding either to the Residential Low Capacity, the Residential Moderate Capacity, Residential Medium, or the Residential High-Capacity zoning districts described in Subsection 20.36.010 (Residential Districts Established). Within that portion of the MPN district that is developed for medium or higher density residential purposes, all development must be in accordance with the regulations applicable to the residential district to which the particular MPN zoning district corresponds. (iii) A third element of each MPN district may be the commercial element. Here there is one possibility, corresponding to the Neighborhood Commercial district identified in §20.36.020 (Commercial Districts Established). Within that portion of a MPN district that is developed for purposes permissible in a NC district, all development must be in accordance with the regulations applicable to the NC district. (iv) A public services/facilities element may be a fourth element of any MPN district. Here uses permitted within the Public/Semi-Public district would be permitted within the MPN district. If a P/SP element is included, then within that portion of the MPN district that is developed for purposes permissible in a P/SP district, all development must be in accordance with the regulations applicable to the P/SP district. (2) The approximate locations, types, and sizes of public facilities and amenity areas
(e.g., parks, schools, open space, common landscaped areas, etc.); (3) Conceptual infrastructure plans (e.g., location, types, and sizes of streets, sewer, water, stormwater, etc.); (4) Compliance with those portions of the City’s Development Design Standards having to do with neighborhood design pursuant to Chapter 20.46, Design; (5) Public infrastructure financing strategies (including any improvements to existing on- or off-site facilities necessary to support the MPND); and (6) An anticipated phasing and/or build out schedule, subject to an analysis of service capacity by the City. (g) Unless the City’s SEPA Responsible Official determines otherwise, the applicant shall develop a programmatic Environmental Impact Statement for the MPN permit. Subsequent development permits may then rely on this EIS to the extent feasible to minimize additional SEPA review. It shall be the intent of the City that during subsequent permitting no additional SEPA review would be required for any action or impact analyzed in the programmatic EIS, unless unforeseen or extraordinary environmental issues arise. (h) In a Master Planned Neighborhood Development, once the master plan is approved and zoning districts assigned per (f)(1), the developer may make use of the land for any purpose authorized in those particular districts, subject to the provisions of the master plan and this title. (i) In those areas of the MPND assigned to the Residential Ultra Low Capacity, lots adjacent to critical areas may be reduced in size and width to a minimum of six thousand square feet and a width of sixty feet so long as the standard of §20.48.030(a) (Lot Shape and Minimum Lot Widths) is met and so long as a gross density of four dwelling units per acre is not exceeded. (j) As indicated in the Tables of Permissible Uses a Master Planned Neighborhood
Development is the only permissible use of a MPN district, and Master Planned Neighborhoods are permissible only in such zones. (k) In approving the MPND the Council may require that the MPND comply with any site-specific development regulations that the City may develop.
20.44.032 Subarea Plans
(a) The Comprehensive Plan designates fourteen subareas that distinguish specific geographical areas
and existing neighborhoods within the community. The intent of creating subareas is to develop a
subarea plan for each area of the city that contains specific policies and criteria to guide land
development, incorporate missing middle housing options, transportation facilities, community
facilities, infrastructure and capital improvement decisions that provide for a more coordinated,
efficient, and effective structure for predictable neighborhood planning. The subarea plans
encompass both newly created subareas and those that work with existing neighborhoods to provide
criteria for infill and redevelopment purposes.
(b) The subarea plans are to be produced by the city, with the exception of two areas designated on the
City’s Zoning Map and Future Land Use Map with the Master Planned Neighborhood (MPN)
Overlay. These two areas are known as East Hill and Lindsay Annexation (portion of Hilltop). The
list of subareas is listed below:
(1) Arlington Terrace
(2) Cascade Industrial Center
(3) Crown Ridge
(4) East Hill
(5) Edgecomb
(6) Gateway
(7) Gleneagle
(8) Haller City
(9) Hilltop
(10) Island Crossing
(11) Kent Prairie
(12) Old Town
(13) Smokey Point
(14) West Bluff
(c) A subarea plan is typically developed to encompass the entire subarea, however under certain
circumstances it may be developed to include only specific neighborhoods, corridors, downtown,
or other types of special districts that show cohesive characteristics. The East Hill and Lindsay
Annexation subareas shall be developed in their entirety.
(d) As subarea plans are created, elements of form based code are proposed to be included to provide
the community with a predictable design and development pattern that is customized for the

to the construction and use of accessory dwelling units; amending RCW 2
36.70A.696, 43.21C.495, and 36.70A.280; adding new sections to 3
chapter 36.70A RCW; adding a new section to chapter 64.34 RCW; adding 4

BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF WASHINGTON:9
NEW SECTION. Sec. 1. (1) The legislature makes the following 10
findings:11
(a) Washington state is experiencing a housing affordability 12
crisis. Many communities across the state are in need of more housing 13
for renters across the income spectrum.14
(b) Many cities dedicate the majority of residentially zoned land 15
to single detached houses that are increasingly financially out of 16
reach for many households. Due to their smaller size, accessory 17
dwelling units can provide a more affordable housing option in those 18
single-family zones.19
(c) Localities can start to correct for historic economic and 20
racial exclusion in single-family zones by opening up these 21

neighborhoods to more diverse housing types, including accessory 1
dwelling units, that provide lower cost homes. Increasing housing 2
options in expensive, high-opportunity neighborhoods will give more 3
families access to schools, parks, and other public amenities 4
otherwise accessible to only the wealthy.5
(d) Accessory dwelling units are frequently rented below market 6
rate, providing additional affordable housing options for renters.7
(e) Accessory dwelling units can also help to provide housing for 8
very low-income households. More than 10 percent of accessory 9
dwelling units in some areas are occupied by tenants who pay no rent 10
at all; among these tenants are grandparents, adult children, family 11
members with disabilities, friends going through life transitions, 12
and community members in need. Accessory dwelling units meet the 13
needs of these people who might otherwise require subsidized housing 14
space and resources.15
(f) Accessory dwelling units can meet the needs of Washington's 16
growing senior population, making it possible for this population to 17
age in their communities by offering senior-friendly housing, which 18
prioritizes physical accessibility, in walkable communities near 19
amenities essential to successful aging in place, including transit 20
and grocery stores, without requiring costly renovations of existing 21
housing stock.22
(g) Homeowners who add an accessory dwelling unit may benefit 23
from added income and an increased sense of security.24
(h) Accessory dwelling units provide environmental benefits. On 25
average they are more energy efficient than single detached houses, 26
and they incentivize adaptive reuse of existing homes and materials.27
(i) Siting accessory dwelling units near transit hubs, employment 28
centers, and public amenities can help to reduce greenhouse gas 29
emissions by increasing walkability, shortening household commutes, 30
and curtailing sprawl.31
(2) The legislature intends to promote and encourage the creation 32
of accessory dwelling units as a means to address the need for 33
additional affordable housing options.34

"I am returning herewith, without my approval as to Section 5,
Engrossed House Bill No. 1337 entitled:
"AN ACT Relating to expanding housing options by easing barriers
to the construction and use of accessory dwelling units."
Section 5 of the bill gives local governments authority to waive or
defer fees, defer payment of taxes, or waive other regulations for
the development of accessory dwelling units (ADUs) if specified
conditions are met. The specified conditions are that the ADU must be
located within an urban growth area, and the ADU must be subject to a
locally adopted covenant program ensuring that the ADU will be
primarily utilized for long-term housing. Current law allows local
governments to waive fees, taxes, and to establish various incentives
for the construction of ADUs without requiring the creation of a
local covenant program. The administrative costs necessary to
administer a new covenant program for ADUs may cause some cities to
discontinue current incentive programs.
For these reasons I have vetoed Section 5 of Engrossed House Bill No.
1337.
With the exception of Section 5, Engrossed House Bill No. 1337 is
approved."

Introduction
Allowing more accessory dwelling units (ADUs) encourages housing construction and increases the overall
supply and variety of housing options, helping address the challenges posed statewide by insufficient housing.
HB 1337, passed in 2023, requires jurisdictions to allow two ADUs per lot within urban growth areas (UGAs)
by six months after the next periodic update due date. The Washington State Department of Commerce
(Commerce) presents this publication as an update to the agency's 1994 guidance to assist local governments
in implementing this requirement. The objective is to provide information on the requirements, local policy
choices, and examples of approaches for consideration by cities, towns, and counties, in accordance with the
bill. This guidance is structured into the following sections:
Requirements for cities and other urban areas.
Recommendations for cities and other urban areas.
Key considerations for counties (rural and resource lands).
Other programmatic elements to consider.
This document provides detail on the state law and local policy choices. Please note that throughout this
document quoted state laws are bolded.
Benefits of ADUs
Construction of new ADUs has many benefits, including to:
Add to the diversity of housing options.
Provide a housing type that blends in well with existing low density residential neighborhoods.
Cater to our state’s changing demographics, including more seniors and smaller household sizes.
Provide housing that is typically more affordable than traditional detached single-family homes.
Add housing units without expanding urban growth areas.
Correct historic economic and racial exclusion by opening up single-family neighborhoods to more
diverse housing and household types.
Reduce climate impacts because ADUs tend to be smaller and use less energy than traditional single-
family homes.
Use existing infrastructure such as sewer, water and streets.
For these reasons, ADUs can be an effective and “gentle” way of helping to accommodate the state’s growing
population.

Definitions
Local governments should review their development
regulation definitions to ensure consistency with RCW
36.70A.696, as amended. This will help facilitate
consistent implementation of these requirements and
reduce the need for interpretation due to missing or
outdated definitions.
Accessory Dwelling Unit (ADU)
A dwelling unit located on the same lot as a single-
family housing unit, duplex, triplex, townhome or other
housing unit.
Attached ADU
An ADU located within or attached to a single-family
housing unit, duplex, triplex, townhome, or other
housing unit.
Detached ADU
An ADU that consists partly or entirely of a building
that is separate and detached from a single-family
housing unit, duplex, triplex, townhome or other
housing unit and is on the same property.
Dwelling Unit
A residential living unit that provides complete
independent living facilities for one or more persons
and that includes permanent provisions for living,
sleeping, eating, cooking and sanitation.

Legal History of ADU Policy in Washington State
As required by the 1993 Washington Housing Policy Act, Commerce made recommendations to encourage
development and placement of ADUs, published in 1994 as the Model ADU Ordinance Recommendations. The
Act required cities of over 20,000 population and counties of over 125,000 population, planning under the
Growth Management Act to incorporate the Commerce recommendations into their zoning and development
regulations. To allow local flexibility, the recommendations were subject to local regulations, conditions,
procedures, and limitations.
In 2019, the state Legislature found that Washington State had a housing affordability crisis and sought to
promote and encourage the creation of ADUs. Commerce offered a grant program1 to encourage cities to
adopt regulations to increase housing supply, including to: (1) authorize ADUs in one or more zoning district in
which they are currently prohibited; (2) remove minimum parking requirements; (3) remove owner occupancy
requirements; (4) adopt new square footage requirements that are less restrictive than existing requirements;
and (5) develop a local program that offers homeowners a combination of financing, design, permitting or
construction support to build ADUs.2
In 2020, the legislature adopted restrictions on how much off-street parking local governments could require
for ADUs near transit stops. As a result, cities that fully plan under the GMA could not require off-street parking
for ADUs within a quarter mile of a major transit stop, with certain limited exceptions.3
In 2021, the legislature amended RCW 36.70A.070(2)4 to require all cities and counties that fully plan under the
GMA to "consider the role of accessory dwelling units in meeting housing needs." In addition, Section 7 of the
bill stated that cities and counties “should consider” certain policies to encourage the construction of ADUs.
Governor Jay Inslee vetoed this section because it did not specifically limit the policies to lands within urban

growth areas. The Governor’s veto illustrates a fundamental point: While there is little doubt that local
governments should encourage ADUs in cities and UGAs, very different considerations come into play with
respect to county rural and resource lands.
In 2023, HB 1337 amended RCW 36.70A to add significant changes to local government roles for regulating
ADUs. Within urban growth areas, cities and counties:
Must allow two ADUs per residential lot. They may be attached, detached, or a combination of both, or
may be conversions of existing structures.
May not require the owner to occupy the property, and may not prohibit sale as independent units.
May not charge more than 50% of impact fees charged for the principal unit.
Must allow an ADU of at least 1,000 square feet and must adjust zoning to be consistent with the bill
for things such as height, setbacks, and other regulations.
Must set consistent parking requirements based on distance from transit and lot size.
If a city or county does not amend its rules to be consistent with the law, the statute will "supersede, preempt
and invalidate any conflicting local development regulations."5
Other new provisions in HB 1337
Actions taken by a city or county to comply with new requirements are exempt from legal challenge
under GMA or SEPA.6
Cities and counties are not required to authorize the construction of an ADU where development is
restricted under rules as a result of physical proximity to on-site sewage system infrastructure, critical
areas, or other unsuitable physical characteristics of a property.7
Cities and counties may restrict the use of ADUs for short term rentals.8
Cities and counties may apply public health, safety, building code, and environmental permitting
requirements to an ADU that would be applicable to the principal unit, including regulations to protect
ground and surface waters from on-site wastewater.9
ADUs are not required to be allowed on lots with critical areas, or around SeaTac airport.10
Local governments are protected from civil liability if they issue a permit for an ADU on a lot with a
covenant or deed restricting ADUs.11

Requirements for cities and urban growth areas
1. Allow two ADUs per lot
Allowing ADUs in residential neighborhoods creates additional housing options and gives homeowners greater
flexibility by providing rental income or a place for they or their family members to age in place.
State law
Within urban growth areas, cities and counties must allow two ADUs on all lots in zoning districts that allow
for single-family homes.12 The ADUs may be:
Two attached ADUs such as unit in a basement, attic, or garage;
One attached ADU and one detached ADU; or
Two detached ADUs, which may be comprised of either one or two detached structures.
A conversion of an existing structure, such as a detached garage.13
When lots are small
Cities and counties must allow an ADU on any lot that meets the minimum lot size required for the principal
unit.14 Minimum lot sizes set the base lot size for development as part of a subdivision process. To support
more ADU development, local governments should reduce or eliminate minimum lot size requirements for
12 RCW 36.70A.681(1)(c)
13 RCW 36.70A.681(1)(j)
14 RCW 36.70A.681(1)(e) states that an ADU must be allowed if the lot meets minimum size for the principal unit. RCW 36.70A.681(3)
states that cities and counties may set a limit of two ADUs, on a residential lot of 2,000 square feet or less. However, if two ADUs are
allowed on lots that meet the minimum lot size, 2,000 SF is not generally going to be a standard lot size and may not have sp ace for
even one ADU.

ADUs with existing development and allow ADUs on all lots. Where lots are smaller than the minimum allowed
by the zone, cities may choose to rely on the capacity of the lot, sewer, septic, parking, and landscaping or
other regulations to set the limits on one or two ADUs.
Examples
Enumclaw Municipal Code Sec. 19.34.050: Allows ADUs on lots of any size.
Kenmore Municipal Code Sec. 18.73.100: Does not require a minimum lot size for ADUs.
Renton Municipal Code Sec. 4-2-110C: Permits ADUs on lots 3,000 square feet or less.
Restricted development locations
Cities and counties are not authorized to allow construction of ADUs in locations where development is
restricted under other laws, rules, or ordinances due to physical proximity to on-site sewage system
infrastructure, critical areas or other unsuitable physical characteristics of a property.15 This includes critical
areas protection standards, such as buffers and setbacks, as well as associated environmental permitting
review and process requirements. In short, cities and counties should apply the same public health, safety,
building code and environmental permitting requirements to an ADU that would be applicable to the principal
unit, including regulations to protect ground and surface waters from on-site wastewater. The provisions of HB
1337 provide no authority to override local ordinances that address public health and safely.
Cities and counties may restrict ADU development:
Within areas designated as critical areas (see below).
In shoreline areas so designated under a shoreline master program (see below).
On lots in a watershed serving a reservoir for potable water if that watershed is or was listed, as of
July 1, 2023, as impaired or threatened under Section 303(d) of the federal Clean Water Act (33
U.S.C. Sec. 1313(d)).16
In zones with a density of one dwelling unit per acre or less that are in critical areas, designated as
wetlands, fish and wildlife habitats, flood plains, or geologically hazardous areas.17 Generally any
zones with such low densities within UGAs are so designated to protect the critical area, so adding
additional development in the form of an ADU is not consistent with this exception.
Within a mile radius of SeaTac airport.18
For areas without sewer
Cities/counties may prohibit ADUs on properties not served by sewers.
Septic and related wastewater rules to protect water-quality located in local health codes and 246-272A
and -272B WAC continue to apply to on-site systems for ADUs.
The Department of Health expects attached ADUs to be more likely to be connected to the same septic
system as the primary single family residence since they are easier to build compliant with Department
of Health rules. The septic system needs to be designed to accommodate this additional wastewater
flow.
Detached ADUs could, depending on local rules, be served by a separate septic system. The
requirements, including horizontal setback and maximum density requirements of the rule(s) would
apply.

In areas where sewers are likely to be built in the future, plan reviewers may want to take measures to
accommodate the eventual conversion from septic systems to sewer.
Critical areas
Cities and counties shall limit ADU development as necessary to meet critical areas protection standards. All
ADU development must be reviewed for consistency with critical area protection ordinance provisions, and
shall only be allowed when consistent. Critical areas include:
Wetlands, and fish and wildlife habitat conservation areas provide critical ecological functions. They are
protected for their intrinsic values and no additional development is appropriate. Internal conversions of
existing space to an ADU may be permissible, provided all other protections are observed.
Floodplains and geologically hazardous areas are identified as hazard areas that may pose dangers to life
safety and property. Most local jurisdictions allow some development in floodplains and geologically
hazardous areas. However, the development must go through a detailed review process that provides
analysis of the site-specific conditions and the proposed development, supported by reports from certified
experts such as geologists and engineers.
Critical aquifer recharge areas (CARAs), which are important to allow groundwater to recharge aquifers
used for drinking water. In these areas, regulations generally protect against hazardous uses and ensure
impervious surfaces do not restrict groundwater recharge. ADU development over CARAs may be allowed
if it can be demonstrated they will not impact potable water.
While ADUs shall be allowed in residential neighborhoods within the UGA, in geohazard and wetland areas they
must be designed and located to avoid critical area impacts consistent with the mitigation sequence,19 which
includes to:
Avoid the impact altogether by not taking a certain action or parts of an action.
Minimize impacts by limiting the degree or magnitude of the action and its implementation by using
appropriate technology, or by taking affirmative steps to avoid or reduce impacts.
Rectify the impact by repairing, rehabilitating or restoring the affected environment.
Reduce or eliminate the impact over time through preservation and maintenance operations during the
life of the action.
Compensate for the impact by replacing, enhancing, or providing substitute resources or environments.
Monitor the impact and taking appropriate corrective measures.
Reasonable use exceptions
Detached ADUs are not necessary for reasonable residential use within critical areas and should not be
allowed within critical areas or their buffers under reasonable use exceptions. It may be possible to convert
space within existing homes to create an ADU if no new exterior construction, expansion of the footprint or
additional impervious surface is added.

ADUs in shorelines under a shoreline master program
Shorelines and shorelands are governed under the city, town, or
county’s Shoreline Master Program (SMP). Although residential uses
are allowed in many shoreline environment designations (SEDs), ADUs
may not be appropriate in all SEDs. The ADU requirements outlined in
HB 1337 are intended to apply within the UGA governed under the
Growth Management Act and are not automatically applicable within
the shoreline jurisdiction governed under the Shoreline Management
Act (SMA). Local governments should plan for ADUs located within
shoreline jurisdiction during a periodic review of their SMP20. Review
and update of an SMP is required every ten years but can be initiated by
a local government outside of the required schedule.
Chapter 90.58 RCW, Chapter 173-26 WAC, and Ecology approved local
shoreline master programs restrict development under SMA goals,
policies, purpose and intent. Within shoreline jurisdiction, zoning code
provisions can be applied, but they must be reviewed in addition to the
bulk, dimensional, performance, and use standards of the SMP, and all
new development and uses, including ADUs, can only be authorized
through the shoreline permitting system outlined in Chapter 173-27
WAC.
Each SMP contains residential use regulations and development standards which ensure that allowed uses
and development remain compatible with the shoreline environment and SMP and allow no net loss of
shoreline ecological function. If allowed under the SMP provisions, ADUs would still need to be located outside
of all shoreline buffers and setbacks and would need to meet other SMP critical area, density, impervious
surface, and vegetation conservation provisions.
ADUs are not necessary for reasonable residential use within shoreline jurisdictions and should not be
included as project components in shoreline variance permit applications.
Local governments wanting to address ADUs under the authorities of their SMP should consult Washington

2. Do not require owner occupancy
Owner occupancy standards have typically required that a property owner live in either the primary residence or
the ADU, however that may limit the ability of the owner to develop or rent and ADU.
State law
Within UGAs, cities and counties may not require the owner of a lot on which there is an ADU to reside in or
occupy the ADU or another housing unit on the same lot.23 RCW 36.70A.696(9) defines owner as any person
who has at least 50% ownership in a property on which an ADU is located.
Local policy choice
When a unit is used as a short-term rental (STR), a local government may choose to require an owner to
occupy either the primary or an accessory unit. (See the section on short-term rentals.)24
Examples
Bremerton Accessory Dwelling Units
Kirkland Accessory Dwelling Units
Seattle Accessory Dwelling Units
Vancouver Accessory Dwelling Units
3. Allow separate sale of ADUs
Because they are smaller and generally more affordable than most typical single-family homes, sales of ADUs
as separate units can increase homeownership opportunities for first-time homebuyers and low-income
households.
State law
A city or county may not prohibit the sale or other conveyance of a condominium unit independently
of a principal unit solely on the grounds that the condominium unit was originally built as an
accessory dwelling unit.25 Washington’s Condominium Act, which provides for the creation of
condominiums, does not preclude ADUs from being created as a part of a condominium development.
Here, the unit is individually owned and the remainder of the property is under common ownership.
Local governments wanting to regulate how ADUs are converted to a condominium form of ownership
should work closely with their legal counsel in reviewing RCW 64.90.025 and other related laws.26
Zero lot line subdivisions and lot splits are mentioned in Section 4(2) of HB 1337, however, there is
currently no authorization for lot splits in Washington, creating true independent units for ADUs. SB
5258 amends RCW 58.17.060 to require all cities and towns to adopt procedures for unit lot
subdivisions to allow division of a parent lot into separately owned unit lots, or owned in common by
the owners of the lots. However, this is better used for developments such as townhouses.

4. Set off-street parking requirements consistent with HB 1337
Many lots in established areas aren’t large enough to support both an ADU and off-street parking, effectively
prohibiting ADU development. This means that ADUs are often limited to larger lots that can accommodate
parking and other site features. Removing off-street parking requirements for ADUs can help to open up
possibilities for placing ADUs, especially in urban areas with transportation options.
State law
Parking limits for ADUs are subject to the following:
Off street parking may not be required as a condition of permitting ADUs within one half mile of a
major transit stop.27-28
On lots smaller than 6,000 square feet, no more than one off-street parking space may be required
per ADU before any zero lot line subdivisions or lot splits.29
On lots greater than 6,000 square feet, no more than two off-street parking spaces per ADU may be
required before any zero lot line subdivisions or lot splits.
Local policy choice
While on-site parking cannot be required within a half mile of a major transit stop, a city may not want to
require on-site parking in other types of walkable areas or where on-street parking is sufficient. Cities may also
choose to reduce parking requirements from the maximum limits in statute. Because ADUs typically are for
one or two people, no more than one parking space may be needed for any lot size, especially in areas with on-
street parking.
A parking study
Cities may choose to require more parking if Commerce concurs with a locally-conducted empirical study
prepared by a credentialed transportation or land use planning professional that clearly demonstrates that
parking consistent with the law would be significantly less safe for pedestrians, bicyclists, or people in
vehicles than if the jurisdiction's parking requirements were applied to the same location for the same
number of detached houses.30 Commerce is required to develop guidance on the contents of the study by the
end of 2023.
Related to the issue of off-street parking requirements are garage conversions for ADUs. This type of ADU may
be more affordable since the changes are primarily internal to an existing structure, and they’re popular with
retirees who want to age in place because they generally have “no-step entries.” Because HB 1337 requires
cities to allow garage conversions, and to reduce parking requirements, Commerce recommends that cities
allow any replacement parking for the primary residence and ADU to be on driveways or on the street if
27 Under RCW 36.70A.681(2), off-street parking for ADUs is prohibited within 1/2 mile of a major transit stop.
28 Major transit stop is defined in RCW 36.70A.696.
29 This part of statute references zero lot line subdivisions, however, for the purposes of this guidance, this means the ADU is not
subject to primary unit parking requirements, even if subdivided from the primary unit.

possible. Low impact development pervious pavement options may be an offset tool to address additional
parking, while also reducing overall site impervious surface area.
Examples
Fircrest Municipal Code Sec. 22.58.012 – Doesn’t require additional off-street parking for ADUs unless the
planning director determines there is insufficient on-street parking to satisfy parking demand.
Kenmore Municipal Code Sec. 18.73.100 – No additional off-street parking spaces are required for an
ADU.
Sumner Municipal Code Sec. 18.12.030 – ADUs created via garage conversion are not required to have off-
street parking, as long as there is available on-street parking and the unit is located within half a mile of the
Sumner transit station.
Kirkland Municipal Code Sec. 115.07 – Doesn't require off-street parking for one ADU. On lots with more
than one ADU, one space is required, with exceptions (available street parking within 600 feet or property is
located within 1/2 mile of frequent transit).

5. Set maximum size limits at no less than 1,000 SF
Local governments typically enact maximum size limits for buildings to ensure there is enough space on a lot
for site features like parking and green space. However, maximum size limits that are too restrictive pose
design and use limitations. ADU size limits are typically smaller in urban infill areas than they are for larger
greenfield sites. Some cities and other urban areas set a single maximum that is based on square footage,
while others couple this standard with a percentage of the primary residence.
State law
ADU size limits must allow a gross floor areas of at least 1,000 square feet within UGAs.31 New amendments
to RCW 36.70A.969 define "gross floor area" as the interior habitable area of a dwelling unit including
basements and attics but not including a garage or accessory structure.

Examples
Chelan Municipal Code Sec. 17.20.20 – Limits ADUs in its single-family residential district to 1,200
square feet or no more than 50% of the total square footage of the primary residence, whichever is less.
The planning director may approve an increased size to efficiently use all floor area if all other
standards are met.
Kenmore Municipal Code Ch. 18.73 – Attached ADUs are limited to 1,000 square feet unless the ADU is
proposed for preexisting floor area on a single level of the primary unit. For detached ADUs, maximums
are based on lot size.
6. Reduce setbacks for ADUs (especially rear setbacks)
State law
A city or county may not impose setback requirements, yard coverage limits, tree retention mandates,
restrictions on entry door locations, aesthetic requirements, or requirements for design review for ADUs that
are more restrictive than those for principal units.32
A city or county must allow detached ADUs to be sited at a lot line if the lot line abuts a public alley, unless
the city or county routinely plows snow on the public alley.33
Setback requirements, which establish the minimum distance from front, side, or rear lot lines, create space
between a building and adjacent uses. Some codes establish setbacks for ADUs that mirror those of the
principal unit, thereby limiting space for ADUs, especially detached ADUs on small lots. Many urban
communities have begun requiring separate, less restrictive setbacks specifically for ADUs. For example, some
cities and other urban areas reduce or waive setbacks for detached ADUs alongside and rear lot lines, and
alleys.

setbacks when abutting an alley.
LaCenter Municipal Code Ch. 18.247 – Allows detached ADUs at the rear yard lot line if adjacent to an
alley.
Zoning codes should clearly describe ADU standards, which should be at most the same as those for the
primary unit. When ADUs are added on a lot, they should fit on the lot, and be consistent with yard coverage
limits and tree retention provisions. Stormwater low impact development features such as rain gardens and
other bioretention options can be used to define setback areas for an ADU and principal lot, and should be
features to support additional units, rather than be barriers. 34
7. Limit use of design standards
Design standards often involve ensuring ADUs are compatible with the primary residence through features
such as architectural style, window placement, roof form and pitch, and building materials. ADU design
standards, however, can have the unanticipated impact of increasing project costs by lengthening the time
needed for local ADU project review. ADUs can complement, but need not be exactly the same as the principal
unit. Design standards must be clear and objective, should be no more prescriptive than those for single-family
34 Commerce's guidebook: Incentivizing Low Impact Development (LID) Beyond Permit Requirements includes tools and outreach
materials that local governments can utilize to encourage developers to go beyond existing stormwater requirements and help reduce
site impervious areas.

homes, and may not result in a reduction in density, height, bulk, or scale below the requirements of the
underlying zone.35
State law on design standards
A city or county may not impose setback requirements, yard coverage limits, tree retention mandates,
restrictions on entry door locations, aesthetic requirements, or requirements for design review for ADUs that
are more restrictive than those for principal units.36
Local governments should minimize the use of ADU design standards. In some cases, standards may be used
to address privacy, for example making sure that the ADU’s windows are located to preserve privacy between
the ADU and neighboring properties or private open space.
HB 1293 (laws of 2023) adds to RCW 36.70A and amends RCW 36.70B to streamline local design review
processes, requiring “clear and objective” standards that don’t reduce development capacity otherwise
allowed. Any design review process must be conducted concurrently, or otherwise be logically integrated, with
the consolidated review and decision process for project permits set forth in RCW 36.70B.120(3). No design
review process may include more than one public meeting. A county or city must comply with these
requirements beginning six months after its next periodic update required under RCW 36.70A.130. The
provisions do not apply to regulations specific to designated landmarks or historic districts established under
a local preservation ordinance
Examples
Ellensburg Municipal Code Sec. 15.540.040 – Does not require ADUs to match the appearance of the
primary structure.
Sedro Woolley Municipal Code Sec. 17.100.030 – Allows the planning director to approve interesting
detached ADU designs that are dissimilar from the primary structure.

though duplex-like designs are not allowed.

8. Allow ADUs of at least 24 feet in height
State law
The city or county may not establish roof height limits on an ADU of less than 24 feet, unless the height
limitation on the principal unit is less than 24 feet, in which case, a city or county may not impose roof height
limitation ADUs is less than the height limit that applies to the principal unit.37
Cities and other urban areas typically set building height limits to address issues like views and privacy;
however, they also limit design options and use land less efficiently. Some communities set one height limit
for both the principal unit and ADUs, while others have a separate maximum for ADUs.
Examples

9. Reduce impact fees
Impact fees
Impact fees are one-time charges assessed by a local government against a new development project to help
pay for new or expanded public capital facilities that will directly address the increased demand for services
created by that development. RCW 82.02.050 authorizes counties, cities, and towns planning under the Growth
Management Act (GMA) to impose impact fees for:
Public streets and roads;
Publicly owned parks, open space, and recreation facilities;
School facilities; and
Fire protection facilities.
Because ADUs are generally smaller than standard single family homes, they typically have fewer people living
in them, and likely cause fewer impacts.
State law
The city or county may not assess impact fees on the construction of accessory dwelling units that are
greater than 50 percent of the impact fees that would be imposed on the principal unit.38
38 RCW 36.70A.681(1)(a) and SB 5258 (section 10, laws of 2023) amends RCW 82.02.060 to require local governments to publish a
schedule of impact fees which reflects the proportionate impact of new housing units. This includes multifamily and condo units,
based on square footage, number of bedrooms or trips generated, to produce a proportionally lower impact fee for smaller housing
units. Local governments must adopt this schedule within six months after the periodic update due date.

Local policy choice
Local governments may charge according to the size of the unit, fixture count, or location with the community,
or completely waive fees, but in no case should the fees be more than 50% of what would be charged to the
principal unit.
Examples
Everett 2023 Impact Fees Schedule – Waives transportation and school impact fees for ADUs.
Olympia Municipal Code Ch. 15.08 – Waives school impact fees and reduces transportation and park
impact fees for ADUs.
Renton 2019-2020 Fee Schedule (Section XII) – Provides impact fee reductions and waivers for ADUs.
Lake Stevens Municipal Code Sec. 9.25.010 – Reduces utilities connection fees for ADUs based on
ADU size.
Utility connection fees/system development charges
System development charges, or connection fees may be charged for area-wide improvements for water,
sewer or stormwater. Like impact fees, communities may charge according to the unit’s impact on the system.
A fundamental feature of ADUs is that the ADU is “accessory to” a primary residential unit. As a result, the ADU
will be smaller, typically have fewer people living in it, and have a reduced demand for municipal services.
Metering considerations when connecting to the sewer system
The Department of Health considers an ADU a separate dwelling unit if it is located outside and separate from
the single family residence (detached). An ADU located within the single-family residence, such as a basement
or attic unit, is generally not considered a separate connection to the sewer system for the purposes of
metering. The total number of service connections is determined by counting each single-family home, each
dwelling unit in a multi-family building, and each nonresidential building that the water system serves.
Local policy choice
There is no specific requirement to reduce charges for sewer, water and stormwater, as there is for impact
fees, but a local government has the option of removing, reducing or waiving connection fees or system
development charges to meet public purposes. Because of the dependent nature of ADUs, it is recommended
that local governments allow shared meters, especially for attached units that are within the capacity of an
existing meter. There may be limited cases in which separate meters are necessary because of site
configuration or separate sale. They may choose to reduce system development charges to 50% as well
because these charges are meant to fund area wide system development improvements, and an ADU generally
has a smaller impact.
Examples
King County has a detailed system capacity charge system with charges that vary based on the size
and form of the housing unit, with addition discounts for affordable units.

when developing an ADU. There is no charge when the connection occurs on the lot. The Olympia
Engineering and Design Standards Section 7B.080 addresses the issue of ADUs and side sewers.
Sedro Woolley Municipal Code Sec. 17.100.030 – Utilities may be shared between an ADU and the
primary dwelling. Sewer connection fees are collected at a reduced rate depending on the size of the
ADU.
10. Other Fees and Exactions
State law
A city or county may not require public street improvements as a condition of permitting ADUs.39
State law requires that public street improvements must not be required as a condition of permitting ADUs,
even if the development of the primary unit can trigger such improvements.
Another barrier might be the cost of permit fees. Local governments often attempt to recoup the actual cost of
processing land use permits, but there is not a legal requirement that they do so. A city or county could choose,
for policy reasons, to charge a lower amount for ADU applications as part of a strategy to encourage property
owners to construct new ADUs on their properties. In addition, lowering fees makes sense if a city or county is
taking other steps to streamline the ADU process, since those measures may also result in lower permit
administration costs.
Examples
Spokane Municipal Code Sec. 08.02.031 – Waived permit fees for ADUs on lots within half a mile of
certain zoning districts. The waiver is set to expire at the end of 2024.
Washougal Municipal Code Sec. 18.46.020 - Does not charge an application fee for detached ADU
development.
39 RCW 36.70A.681(1)(l). The GMA does not currently define "public street improvements", however "public facilities" is defined in RCW
36.70A.030 and "public improvements" in RCW 39.114.010; both include street and road construction including sidewalks, street and
road lighting systems, storm and sanitary sewer systems, among other public improveme nts.

Recommendations for cities and other urban areas
The following recommendations are not required but are suggestions to encourage the development of ADUs.
They are to apply only to cities, towns, and other urban areas, including unincorporated urban growth areas
(UGAs) and limited areas of more intensive development (LAMIRDs). The purpose of applying these ADU
recommendations to cities and other urban areas, and not to rural areas or resource lands is to support the
GMA's goals of encouraging development in urban areas and reducing sprawl.
1. Allow prefabricated units
Prefabricated detached ADUs can provide a degree of cost savings, which may make them more affordable for
property owners, especially in more remote areas that may not have access to the tradespeople needed to
construct ADUs. Because materials and manufacturing are centralized at an off-site manufacturing facility,
prefabricated units require less construction time than conventionally built structures and can be constructed
year-round in a climate-controlled factory.
RCW 35A.21.312 allows for consumer choice in housing, requiring local government to allow the placement of
factory-built homes in any location where site-built homes are permitted. The law was likely developed to apply
to primary units, and not necessarily ADUs. However, cities and counties may adopt a set of additional
standards, relating to permanent foundation, roof pitch, and design, although not all of those standards should
be applied to ADUs.
Any prefabricated unit must meet state standards.40 Local codes may refer to larger manufactured homes, and
may not be related to small homes, such as park models, more suitable for an ADU.
Example
Bremerton Municipal Code Sec. 20.46.010 – Allows for manufactured homes to be used as ADUs.

Tiny houses
Tiny houses, or tiny houses with wheels, as defined in RCW 35.21.686, are not generally allowed as ADUs
because they may not meet the standards required for a permanent residential unit, such as a foundation,
water supply and sewage disposal. However, some communities are starting to consider allowing tiny homes
on wheels as temporary units, with appropriate connections and tie-downs.41
One exception in state law is that tiny homes on wheels and RVs may be used as permanent living quarters
only when situated in manufactured/mobile home communities, but they are still subject to certain life/safety
and utility hookup requirements per RCW 35.21.684. Tiny houses must be inspected and meet the standards of
the Washington State Department of Labor and Industry.42

2. Streamline ADU permitting processes
A local permitting process should be designed to make it as easy as possible for an applicant to prepare and
submit a development permit application, and for the permit review staff to review and quickly approve it. This
approach should be particularly true for the types of development that a community is actively trying to
encourage, such as ADUs.
Discretionary project permitting processes, such as those requiring conditional use permits, hearings examiner
review, and public hearings add extra time and cost to getting a development project approved. These
processes make sense for situations where a proposed project may be large or have a number of potential

impacts on a neighborhood or community. For small, low-impact development projects that advance adopted
public policy such as new ADUs, a discretionary permitting process creates an unnecessary barrier to ADU
construction.
Local governments should allow ADUs “by-right,” with project review and approval to be done administratively.
Having an expedited or shorter review process for ADUs can also include preferential review of ADU proposals.
Providing pre-approved ADU plans is another method for reducing the time needed to review an ADU proposal
(see provide pre-approved ADU plans below). Streamlining can be additionally bolstered by checklists that
clarify the ADU approval process (see below on providing user-friendly communication materials).
Examples
Pasco Municipal Code Sec. 25.161.030 – ADU applications are approved administratively.
Sequim Municipal Code Sec. 18.66.040 – Requires a single administrative permit for ADU development.
The application must be processed by the community development director within 30 days of submittal
(Sec. 20.01.080).
3. Offer incentives to encourage ADUs that are affordable to lower-
income households
While ADUs are generally more affordable than a typical single-family home, most aren't affordable to
households making less than 80% of the area median income (AMI). To address this issue, some local
governments offer incentives for ADUs that are affordable for lower-income households (that is, less than 80%
AMI) for a set number of years (such as 50 years). These types of incentives usually involve requiring
affordability in exchange for providing a “bonus,” like higher densities in the form of an additional ADU. Local
governments can also support affordability for low-income residents by incorporating ADUs into their
affordable housing funding programs and forming partnerships with community land trusts and other non -
profit organizations.
Local policy choice
There are a number of ways that local governments can offer reductions for affordable housing, most require
some kind of assurance that the unit will remain affordable over time.
RCW 82.02.060(4) also authorizes local governments to offer impact fee reductions or waivers for
affordable housing. An exemption for low-income housing granted under this section, however, must be
conditioned upon requiring the developer to record a covenant that prohibits using the property for any
purpose other than for low-income housing.
RCW 36.70A.540 authorizes local governments to expand affordable housing incentive programs to
include, among other things, fee waivers or exemptions provided the local government is committed to
continuing affordability for at least 50 years.
A local government may offer “tap-in charge” waivers for low-income persons (under RCW 35.92.380 or
RCW 36.94.370).43
Examples
CLTplusOne — A pilot program offered by Durham (NC) Community Land Trustees, which pairs a land
trust home with ADUs on the same lot. Both the primary residence and rental unit are permanently
affordable (see this Shelterforce article on Durham’s Community Land Trust).

eligible households” for a minimum of 50 years.
Key considerations for counties
GMA-planning counties must plan and provide regulatory frameworks for four land use categories in
decreasing order of ADU intensity:
Unincorporated UGAs.44
LAMIRDs
Rural lands
Designated natural resource lands
1. Unincorporated UGAs and LAMIRDs
Unincorporated urban growth areas
In unincorporated UGAs, which are generally intended to have urban services and eventually become or annex
into cities, the requirements in this guidance apply within 6 months of the next periodic update.45
LAMIRDs
Within Limited Areas of More Intensive Rural Development (LAMIRDs), the outer boundary may not change, but
the LAMIRD may be filled in with new development, including ADUs.
2. Rural and natural resource lands
ADU regulations outside of urban growth areas require consideration of a different set of factors than ADU
regulations in cities and urban growth areas. ADU provisions in rural and resource areas must be accompanied
by measures to protect rural character, conserve resource lands, and limit density and sprawl.
One of the benefits of ADUs in urban areas is that under HB 1337, the ADUs can be sold separately and add to
the supply of attainable housing for moderate on maybe lower income households. The same does not hold
true in rural areas, where the ADU cannot be sold separately, and the private cost of transportation and public
cost of transportation-related emissions reduces the public benefit of ADUs in rural areas.
When developing or amending regulations, counties should consider the potential for:
Increased demand for emergency and other services.
Increased traffic on county roads, which may be built to a lower standard.
More housing and increased population in areas potentially prone to wildfires or other natural hazards.
Impact on water supplies.
Conflict with or decrease in land available for agriculture or other natural resource industries.
The Growth Management Hearings Boards (GMHBs) have considered challenges to ADU regulations in rural
and resource designated areas in a handful of counties. Three hearings boards have issued decisions

For areas designated as “rural,” the regulations must be consistent with “rural character” as established in the
rural element of the county’s comprehensive plan.47 RCW 36.70A.030(23) defines rural character as “[...] the
patterns of land use and development established by a county in the rural element of its comprehensive plan.”
Importantly, what constitutes rural character in one county may be different than what constitutes rural
character in another (RCW 36.70A.011). ADUs should not contribute to sprawl or cause residential uses to
predominate over rural uses.48
Given the need to be consistent with and implement their rural, housing, and land use elements of their
comprehensive plans (among others), it will be important for counties to “show their work” through the written
record, including but not limited to whereas statements, findings of fact, staff reports, and public participation
processes; and to articulate legal and policy justifications for their actions.
Designated natural resource lands
Counties must ensure ADU regulations are consistent with GMA requirements to preserve natural resource
lands for resource production. In natural resource lands, the dominant use is to be the agricultural, forestry, or
mineral use; residential development must be located to not interfere with the natural resource use, and
preserve the majority of land for such use.49 See RCW 36.70A.060.
Considerations and examples for rural and resource areas
Generally, regulations permitting attached ADUs raise fewer concerns than those permitting detached ADUs.
While several counties allow detached ADUs in their rural land designations, most include restrictions related
to standards such as:
Size limit on a single ADU.
Minimum lot size to conform to zoning or in some cases, double the minimum lot size.
Proximity to and dependency on the primary residence (such as shared driveway, parking, yard, septic,
well, utilities, etc.).
Design standards for consistency with primary unit.
Limitations on number of permits issued annually.

47 County comprehensive plans must include a rural element. A county’s rural element must include policies that ar e consistent with
rural character. RCW 36.70A.070(5)(b) provides, in relevant part: "[The rural element] shall provide for a variety of rural densities, uses,
essential public facilities, and rural governmental services needed to serve the permitted densities and uses. To achieve a variety of
rural densities and uses, counties may provide for clustering, density transfer, design guidelines, conservation easements, a nd other
innovative techniques that will accommodate appropriate rural economic advancement, densities, and uses that are not characterized
by urban growth and that are consistent with rural character."

Restrictions on title.
Careful with detached ADUs (attached ADUs preferred)
The hearings boards have held that freestanding residential ADUs should be treated as separate dwelling units
for purposes of density calculations — although in some cases have found compliant county regulations that
allow limited exceptions to detached ADUs triggering such density requirements.50
Attached ADUs are Preferred
Conversely, the boards have held that attached ADUs and ADUs converted from an existing structure in close
association with the primary residence (such as a garage) do not count toward density in rural and resource
areas.51
Examples
Clark County: Accessory Dwelling Unit – Rural (Handout) (2022) – Allows only attached ADUs in rural
and resources zones.
Kitsap County: Accessory Dwelling Unit (Handout) (2022) – Requires detached ADUs to be sited within
150 feet of the principal dwelling outside of UGAs. Size limit, 50% of primary unit or 900 square feet,
whichever is smaller. Owner occupancy requirements and design standards apply.
San Juan County Code Sec. 18.40.240 – Limits the number of detached ADU permits outside “activity
centers” and UGAs in any calendar year to no more than 12% of the total number of building permits for
new principal residences issued for the previous calendar year. Further limited to one permit per
property owner outside UGAs.
Spokane County: Detached Accessory Dwelling Unit (Handout) – Detached ADUs in selected rural
zones must be within 150 feet of principal dwelling and meet several other conditions, including that
title notice will be placed on the property that the accessory dwelling may not be sold as a separate
residence until such time as the accessory dwelling is located as the sole residence on a legally
subdivided parcel.
Walla Walla County Code Sec. 17.08.015 – Requires at least four of six “dependency requirements” be
shared for a detached ADU (road access, septic system, water system, utility meters, yard, and parking
areas).
Other programmatic elements to consider
The following “programmatic elements” are not recommendations but are instead meant to be additional
options to be considered by cities, towns, and other urban areas, including unincorporated UGAs and
LAMIRDS.
1. Address the use of ADUs as short-term rentals
Construction of ADUs presents an opportunity to increase a community’s supply of relatively affordable long-
term housing. When an ADU is used as a short-term rental (STR), defined as a housing unit being rented for
fewer than 30 consecutive days, that housing unit functions as a lodging unit for visitors and not as a housing

unit.52 As a result, some local governments completely prohibit the use of ADUs as STRs, while others limit but
don’t completely prohibit that use.
The primary rationale for prohibiting or limiting ADUs being used as STRs is that renting an ADU as a long -term
housing unit, defined as being rented for more than 30 consecutive days, will have the dual benefit of providing
a positive income stream to a homeowner and adding a new residential unit to the local housing supply.
Some studies attempt to make the case that ADUs being used as STRs make up “only a small percentage” of
the overall stock of STRs (8%-12%).53 For example, data collected by the City of Seattle shows that 11% of the
total short-term rental units were ADUs. It should be noted, however, that 11% still represents 418 units that are
not contributing to that city’s long-term housing supply.
Given the significant policy implications, local governments located in areas with high demand for short-term
rentals, such as popular tourist destinations, should carefully consider the pros and cons of allowing ADUs to
be used as short-term rentals.
State law
Cities and counties may restrict the use of ADUs for short term rentals.54
Examples
Bellingham Municipal Code Sec. 20.10.037 – Does not allow STRs in detached ADUs in single-family
zones but does allow them in detached ADUs in other zones, and in attached ADUs citywide.
Poulsbo Municipal Code Sec. 18.70.070 – Does not allow ADUs to be used as STRs. Sequim Municipal
Code Ch. 18.66 – Does not allow ADUs to be used as STRs.
2. Provide user-friendly communication materials
To assist applicants in navigating the ADU permitting process, local governments can provide user-friendly
ADU webpages, informational handouts, guides, and checklists. These guidance documents can help by clearly
articulating ADU requirements to property owners, homeowners, contractors, and developers. Clear materials
inform those who are interested in building ADUs and encourage interest in ADU construction.
Examples
Bremerton Guide to Establishing an ADU (2021) – Includes an overview of the city’s ADU standards and
links to permit requirements.
Lake Stevens ADU Permit Checklist – Helps applicants understand the city’s ADU provisions.
Olympia ADUs & Accessory Structures Guide (2022) – Includes an overview of ADU regulations and
standards, including design review requirements and guidelines.
Seattle ADUniverse: The ABCs of ADUs – Includes a step-by-step guide to creating an ADU.
Thurston County ADU Handout (2021) – Covers the main elements of the county’s three-step ADU
permitting process.
52 RCW 36.70A.696(9) defines short-term rental as "a lodging use, that is not a hotel or motel or bed and breakfast, in which a dwelling
unit, or portion thereof, is offered or provided to a guest by a short -term rental operator for a fee for fewer than 30 consecutive nights."
53 See, for instance, the Urban Land Institute’s report Jumpstarting the Market for ADUs: Lessons Learned from Portland, Seattle, and
Vancouver.

3. Provide information on landlord-tenant laws for prospective ADU
owners and ADU tenants
For many homeowners renting an ADU on their property, this may be the first time they have served as a
landlord. As a result, they may not be familiar with relevant local, state, and federal laws that apply to landlords
(such as the Fair Housing Act). Conversely, renters also have certain rights and responsibilities under these
laws that both landlords and tenants should know.
The Washington Residential Landlord-Tenant Act includes the state’s key landlord-tenant laws.55 Some local
governments have created landlord-tenant regulations and programs with additional protections for renters,
including rental registration and extra notice of rent increases and/or inspections. To inform both landlords
and tenants about these requirements, local governments can develop user-friendly summaries of these
resources and provide them to ADU applicants during the permit process.
Examples
Bellingham: Landlords and Tenants – Includes information on the city’s rental housing regulations,
rental registration and safety inspection program, and more.
Benton County: Renter's Resources – Includes information on fair housing and tenant rights in
Washington.
Burien: Renting in Burien – Includes information on the city’s rental housing inspection program, notice
of intent to sell, and eviction law in Washington.
Olympia: Tenant Protections – Includes information on the city’s rental housing ordinance, FAQs, and
more.
Tacoma: Landlord-Tenant Program – Includes information on the city’s landlord-tenant program.
4. Provide information on ADU financing and funding programs
Lack of funding and financing options is often cited as one of the most prevalent challenges for ADU
construction.56 Lending institutions that finance ADU projects generally don’t allow homeowners to borrow
against a portion of the future value of an unbuilt ADU, further constraining the viability of projects. To support
homeowners in financing their ADU projects, local governments can:
Identify other funding and financing opportunities for ADUs and make these resources available at the
permit center and online.
Develop programs to facilitate access to ADU funding and financing opportunities.
RCW 84.36.400, authorizes counties to provide a three-year property tax exemption for improvements to a
single-family dwelling, including the construction of an ADU, as long as it represents 30% or less of the value of
the original structure. The program was initiated through Chapter 204, Laws of 2020 (2SSB 6231) and
stipulates that dwelling units may be either attached to or within the single-family dwelling or a detached unit
located on the same real property. In 2023, additional provisions were added in King County.57
55 More information on state and federal laws may be found on the Washington Office of the Attorney General’s Landlord-Tenant page
and the U.S. Department of Housing and Urban Development Tenant Rights, Laws and Protections: Washington page.
56 See the UC Berkeley’s Terner Center for Housing Innovation’s article ADU’s for All: Breaking Down Barriers to Racial and Economic
Equity in ADU Construction (2022).
57 SB 5045 offers extended property tax exemptions for ADUs in King County if the unit is affordable.

ADU owners may deduct, for income tax purposes, construction costs over time, annual property taxes, and
shared monthly utility costs from rental proceeds, which may help encourage their development.
Examples
Olympia OlyFed Bank: ADUs Financing – Provides six loan options for ADU construction. See this ADU
Loan Options flyer and ADU Financing presentation for more information.
Spokane Single-Family & Detached ADU Tax Exemption – The City of Spokane highlights the fact that
Spokane County provides a tax exemption for ADUs for the three assessment years after the
completion of the improvement, to the extent the improvement represents 30% or less of the value of
the original structure.
5. Create a program to encourage legalization of unpermitted ADUs
A combination of strong demand for new housing and too many barriers have in some Washington
communities resulted in unpermitted ADUs. Creating a program to allow legalization of unpermitted ADUs can
help promote safe, legal structures and open them up to rental opportunities.
Local governments are encouraged to develop programs to promote the legalization of existing housing units,
which should be done in a manner that ensures ADUs are safe to inhabit.
Examples
Bellingham Municipal Code Sec. 20.10.036 – Allows ADUs existing prior to January 1, 1995, to become
legally permitted, as long as ADU owners submit an application that is consistent with current ADU
regulations and building codes.
Ferndale Municipal Code Sec. 18.34.060 – Allows owners of ADUs established before June 20, 2017, to
submit an application to the city to legally permit the existing unit pursuant to the city’s ADU
regulations.
6. Provide pre-approved ADU plans
After confirming their property is eligible for an ADU, homeowners begin the design process with an architect
or designer. Depending on whether the unit is within an existing structure or free standing, the design process
can add significant time and expense to a project. To streamline this step, some local governments offer
detached ADU plan designs that have been pre-approved for compliance with building codes. ADU applications
with pre-approved plans are typically approved in a shorter timeframe and with reduced permit fees since the
designs have been vetted by staff. Even though the designs have been pre-approved all other code provisions,
like site-specific standards, still apply.
Examples
Olympia: Pre-Approved ADU Plans (Guide) (2021) – The cities of Olympia, Lacey, and Tumwater worked
together to offer four plans that have been pre-approved for compliance with building codes.
Leavenworth: ADU Plans – Offers four pre-approved designs. Each option includes two different styles
– modern and traditional.
Renton: Permit Ready ADU Program – Includes eight pre-approved, designed, and engineered model
base plans, ranging in size from 415 to 1,000 square feet and varying in architectural style.
Seattle: Pre-approved Detached ADUs Program – Offers 10 pre-approved plans for detached ADUs,
including factory-assembled structures that have been approved by the Washington Department of
Labor and Industries.
