SB 5148 Washington Senate · 2025-2026 Regular Session

Ensuring compliance with the housing element requirements of the growth management act.

Senate Bill 5148 creates a new process for Washington state counties and cities to ensure their housing plans comply with state growth management laws. It allows local governments to submit their housing elements and development regulations to the Department of Commerce for review. These plans will not take effect until the Department determines they meet various state housing requirements. The Department can also mandate review for jurisdictions not adequately planning for or producing sufficient housing, especially for diverse income levels. This aims to improve local government compliance with housing goals under the Growth Management Act.

MODERATE
This bill significantly tightens housing accountability by shifting from a voluntary compliance review system to a mandatory 'targeted review' for specific non-compliant jurisdictions. It accelerates review timelines, adds strict criteria for selecting which cities and counties face scrutiny, and imposes stricter penalties for non-compliance, including a ban on denying affordable housing projects.
Scope change
The bill changes the scope of enforcement from a voluntary opt-in system to a mandatory targeted review for up to 10 jurisdictions per year that fail to meet housing production goals or lack diversity in housing types.
TIMELINE

The deadline for the state department to review housing plans was reduced from 120 days to 90 days.

ELIGIBILITY

Compliance review is no longer voluntary; the state will target up to 10 cities or counties annually based on specific failure criteria, such as not meeting countywide housing needs or producing mostly high-income single-family homes.

REQUIREMENT

Cities and counties subject to targeted review must amend their housing plans within 120 days of being notified of deficiencies, with the option to extend this period only by written agreement.

ENFORCEMENT

Non-compliant jurisdictions are strictly prohibited from denying affordable or moderate-income housing developments unless they have received a final compliance decision or meet specific exceptions like workforce housing.

TECHNICAL

Several section numbers and references to other laws were updated to reflect recent legislative changes.
