On Tuesday, Dec. 16, the Seattle City Council adopted its updated Comprehensive Plan, a key requirement of the state’s Growth Management Act (GMA) that sets the city’s 20-year vision. The plan will guide local decisions related to housing, land use, and other priorities to align with Seattle’s long-term goals and community values.
A key update in the Comprehensive Plan is its alignment with House Bill 1110, enacted by the State Legislature more than two years ago. HB 1110 requires local jurisdictions to allow for a broader spectrum of housing choices, including duplexes, townhomes, stacked flats, courtyard apartments, and cottage housing. The law allows for a minimum of four housing units on all residential lots, and at least six on all residential lots within a quarter mile of major transit. By reducing barriers to housing production near jobs and transit, HB 1110 advances the core principles of GMA while maintaining protections for environmentally sensitive and open spaces.
“Seattle’s adoption of its updated Comprehensive Plan means that the city has taken a major step forward in addressing the housing shortage placing homes out of reach for so many,” said Jerry Hall, executive director of the Master Builders Association of King and Snohomish Counties (MBAKS). “We commend Seattle for lowering many barriers to housing choices in the city even as we look ahead to persistent challenges that still exist in the work to make housing more attainable for all. MBAKS will continue to focus on offering our expertise regarding how best to facilitate more housing that is attainable for current residents, newcomers, and future generations.”
Reducing Barriers to Housing in Seattle’s Updated Comprehensive Plan
Seattle’s updated Comprehensive Plan removes several long-standing obstacles to housing production and allows for more efficient use of the city’s buildable land. Notably, the plan:
- Invests in accessory dwelling units as a popular housing option.
- Improves use of limited buildable land for housing.
- Addresses the need for housing and trees.
Persistent Barriers to Housing Options in Seattle’s Updated Comprehensive Plan
Unfortunately, Seattle’s Comprehensive Plan preserves barriers that will continue to drive up the cost of housing for both renters and homeowners.
Under the plan, Seattle’s Department of Construction & Inspections would retain broad subjective discretion when reviewing new housing proposals related to tree canopy management. MBAKS supports the shared goal of maintaining a healthy urban tree canopy but strongly prefers a clearly defined, objective policy framework that provides transparency, predictability, and timely review for applicants.
The plan also relies on arbitrary minimum tree-per-square foot requirements, which further restrict already limited buildable land. These requirements increase the single greatest cost barrier for new housing: the price of land without demonstratable environmental benefit. Homebuilders are already subject to strict regulations that oversee new construction so that our water, air, and soil are appropriately protected. Homebuilders also routinely plant more trees during construction than are removed.
MBAKS members demonstrate their commitment to environmental stewardship by partnering with local jurisdictions through the association’s Planting a Better Tomorrow event.
“While other barriers to housing remain, MBAKS will continue to advocate for policies and partnerships needed to expand Seattle’s housing supply, ensuring everyone has a place to call home,” said Logan Schmidt, MBAKS’s Seattle Government Affairs Manager.
