Final Mayor's Recommended One Seattle Plan 

Legislation to adopt the One Seattle Plan Comprehensive Plan Update is now being considered by the City Council. The One Seattle Plan includes goals and policies, along with an updated growth strategy, that will guide where and how Seattle grows and invests in communities over the next 20 years toward becoming a more affordable, resilient, and equitable city.

The final Mayor's Recommended Plan and legislation has been introduced at the Select Committee on the Comprehensive Plan, with minor revisions, including boundary adjustments to selected Regional, Urban, and Neighborhood Centers.

Permanent legislation to implement HB 1110

Permanent legislation to implement HB 1110 (Middle Housing bill) and other new state requirements are now being considered for adoption by the City Council. This legislation will replace more limited interim legislation approved by the Select Committee on May 21 (with full Council action on May 27). This legislation includes a complete update to Neighborhood Residential zoning to allow a greater variety of housing types, such as duplexes, four-plexes, townhomes, and stacked flats, in all neighborhoods. The legislation makes other changes to Neighborhood Residential and Low-rise zoning to comply with state law and to further City goals.

Racial Equity Toolkit

A Racial Equity Toolkit (RET) is a process to guide the development of the goals and policies in this Plan in order to further racial equity. Conducting a RET is an iterative process of community engagement, analysis, policy development, and evaluation, with each step informing the next. With guidance from the Seattle Office of Civil Rights, we employed a RET process in developing the Mayor’s Recommended One Seattle Plan.

Interim legislation to update standards for Neighborhood Residential and Lowrise zones to comply with HB 1110 by the state’s June 30, 2025 deadline was sent to Council for their consideration:

Draft Legislation for Centers and Corridors

  • Draft Centers and Corridors Legislation
    Proposes to implement rezones in new Neighborhood Centers, in expansions of existing Regional and Urban Centers, and along frequent transit arterials. The legislation includes changes to development standards in Lowrise and Midrise zones.
  • Summaries of the proposed development standards are available for Lowrise and Midrise zones as amended by both Phase 1 and Phase 2 legislation.

Draft Housing Appendix

Since its initial adoption in 1990, the state Growth Management Act (GMA) has required local comprehensive plans to inventory and analyze existing and projected housing needs. The draft Housing Appendix addresses these requirements and provides a wealth of additional data to inform housing policies in the One Seattle Plan, consistent with GMA and regional frameworks.

The state Legislature recently strengthened GMA so that Seattle and other jurisdictions must “plan for and accommodate” housing affordable to all economic segments of the population. Our draft Housing Appendix documents Seattle’s share of projected housing needs for low- and moderate- income households and for emergency housing and shelters and provides analysis on zoned development capacity to meet these needs. In addition, the draft Housing Appendix:

  • Analyzes trends in demographics and housing supply and costs, demonstrating the importance of expanding the diversity of housing types and unit sizes, including moderate density housing and family-sized units affordable at lower cost than traditional detached housing.
  • Discusses barriers to fully address existing and future housing needs, including funding necessary to meet needs among low-income households through housing subsidies. 
  • Documents disproportionate housing challenges faced by households of color and maps existing disparities in access to key components of livability.
  • Analyzes policies and practices that have resulted in racially disparate impacts, exclusion, and displacement and, along with the Anti-Displacement Framework identifies areas that may be at higher risk of displacement as the city grows.
