Seattle's Comprehensive Plan 2025

Where we are in the Comprehensive Plan Process 

Last updated: January 22, 2026 

The City Council passed final legislation on the Comprehensive Plan (CB 120985) and Permanent HB 1110 legislation (CB 120993) on December 16, 2025.

What’s next

The Select Committee on the Comprehensive Plan plans to take up Phase 2 of the Comprehensive Plan this year, depending on transmittal of Phase 2 legislation from the Mayor’s Office.

Last Action

The approval of Comprehensive Plan legislation in 2025 followed a process that involved 17 committee meetings and four all-day public hearings, after receiving Mayor Harrell’s proposed “One Seattle” draft plan in March 2025.

Earlier this year the proposed plan received six separate legal challenges, delaying the process of adoption of the permanent regulations. In April, all six were dismissed by the Seattle Hearing Examiner. While clearing the way for the City Council to continue consideration of both the  Comprehensive Plan and permanent HB 1110 legislation, it did not give the City enough time to meet the June deadline. 

In May, the Select Committee on the Comprehensive Plan voted unanimously to approve amended interim HB 1110 legislation, also known as the ‘middle housing’ bill, which requires cities to allow a broad range of housing types besides single family homes, such as multiplexes, townhouses, and cottage housing.

Background

Seattle’s Comprehensive Plan (“Comp Plan”) is a 20-year vision and roadmap for Seattle’s future. The plan guides City decisions about where we locate housing and jobs, and where and how we invest in transportation, utilities, parks, and other public assets.  

The Mayor’s One Seattle Plan was a major update to the Comp Plan that advanced a vision for the future and aligned with our city’s core values to make Seattle more equitable, livable, sustainable, and resilient for today's residents and generations to come. 

The Mayor’s One Seattle Plan, or updated Comp Plan, was considered by the City Council, led by Select Committee on the Comprehensive Plan.

Pieces of Legislation

Consideration of the updated Comp Plan is complex and involves different pieces and phases of legislation: 

Interim HB 1110 Legislation – This legislation is not a phase of the Comp Plan but must be adopted first, to comply with the state’s HB 1110 implementation deadline of June 30, 2025.  HB 1110, known as the “middle housing” bill, requires cities to allow a broad range of housing types besides single family homes, such as multiplexes, townhouses, and cottage housing.

Then the Council can move onto the three pieces of Comp Plan Legislation:

1. ‘One Seattle Plan’ Comprehensive Plan – This is the legislation to adopt the new updated Comp Plan. The Comp Plan includes an updated future land use map, which establishes the boundaries of Seattle's various place types, such as neighborhood centers, industrial and manufacturing centers, and urban and regional centers. The Comp Plan also identifies policies around the City's growth and anti-displacement strategies.
2. Phase 1 Zoning Legislation – "Phase 1" includes legislation that will implement permanent changes to Seattle's zoning code to comply with HB 1110. This legislation will make changes to Seattle's Neighborhood Residential (NR) zoning, enabling more housing types to be built in neighborhoods across the city. This legislation will not affect the size and shape of Seattle's various place types.
3. Phase 2 Zoning Legislation – “Phase 2” involves zoning changes within new Neighborhood Centers, new and expanded Regional and Urban Centers, and along frequent transit routes. Phase 2 will take a closer look at the zoning of specific parcels within the place types identified in the Comprehensive Plan's future land use maps.
