Legislation to adopt the final One Seattle Plan Comprehensive Plan Update (Council Bill 120985) was adopted by City Council on December 16 and will go into effect on January 21, 2026. Adoption of the One Seattle Plan is a major milestone in our work beginning in 2022 to update the policies that guide how and where we grow and invest in the future of Seattle toward becoming a more affordable, resilient, and equitable city. We will continue this work with a focus on implementation, including several phases of zoning legislation and ongoing collaboration with City departments on next steps toward achieving the goals of the Plan. More information will be available on a new One Seattle Plan website that is forthcoming in 2026.
