One Seattle Plan
What's Happening Now?
Interim Zoning Legislation to Comply with HB 1110
Seattle must adopt zoning changes to comply with House Bill 1110 by June 30, 2025. We sent Interim HB 1110 legislation to City Council on March 26, 2025. Once adopted, the legislation is effective for only a year.
A summary of the legislation and the full ordinance can be found here:
The Mayor also transmitted legislation to adopt the One Seattle Comprehensive Plan to City Council on March 27, 2025. Council must adopt the One Seattle Comprehensive Plan before approving permanent legislation to implement HB 1110 and other zoning changes. More information on Council’s review process is available on their website.
Zoning Update
To implement the Mayor’s Growth Strategy, we are proposing zoning changes that increase housing choices and support vibrant, inclusive neighborhoods. In October 2024, we released a draft Zoning Update proposal including new development standards for Neighborhood Residential zones and changes to allow more apartments and condos in designated Centers and Corridors.
We are now revising this proposal based on public feedback and will transmit legislation to City Council to implement the updated proposal. As mentioned above, we transmitted interim legislation to comply with the requirements of Housing Bill 1110, which Council plans to pass by May 30, 2025. Below are additional key documents relating to the interim legislation and the proposal that was released in October 2024. More information is available on our Zoning Update website.
