Last month the City Council’s Select Committee on the Comprehensive Plan passed legislation to adopt the One Seattle Plan and update Neighborhood Residential (NR) zoning to comply with House Bill 1110. These two pieces of legislation will now go to full council for final approval later this fall. With these Council actions, OPCD achieves a key milestone toward our work to implement a major update to the City’s Comprehensive Plan.
The One Seattle Plan sets a new course for growth and development over the next 20 years. As a centerpiece of the Plan, a new growth strategy increases the ability of neighborhoods across the city to accommodate new and more diverse housing options by expanding our existing Regional and Urban Centers and adding 30 new Neighborhood Centers around transit, local business districts, and amenities like parks and schools. The One Seattle Plan also includes new and expanded policies to address climate change, public safety, housing affordability, and racial and social equity.
HB 1110 compliance legislation will allow new forms of “middle housing” – townhomes, duplexes, fourplexes, cottage housing, and stacked flats. New Neighborhood Residential zoning will allow at least 4 units on each lot and at least 6 units near transit or where affordable units are included. This legislation also includes incentives for additional affordable housing, stacked flats, family-size housing, accessible units, and protections for the city’s tree canopy. An updated version of the HB 1110 compliance legislation as amended by Council is now available, which includes an updated summary of the legislation.
In early 2026, OPCD will transmit legislation to adopt zoning changes in new and expanded centers and along our frequent transit routes. We will begin implementing the One Seattle Plan in collaboration with many City departments as we work together to address Seattle’s most pressing housing needs, to make strategic investments in communities across the city as we grow, and to monitor and report on our progress over time.
