Housing

HB 1345 restricts detached accessory dwelling units (ADUs) - separate small homes on the same lot as a main house - outside urban growth areas in Washington counties. It requires counties to limit each parcel to one ADU, set size limits (max 1,296 sq ft), mandate water metering and sewage capacity documentation, and require ADUs to be within 150 feet of the main home. Counties must enforce penalties for unpermitted ADUs (including $1,000 fines, removal orders, and 3-year permit bans) and track ADU permits for land-use planning updates. The bill applies only to counties allowing such ADUs outside urban areas, not affecting existing urban or rural ADU rules.

SB 6184 updates Washington state's definitions and administrative provisions for homeless youth programs, primarily affecting unaccompanied homeless youth and HOPE centers (facilities providing temporary housing and services). The bill specifically limits stays at HOPE centers to 90 days for most unaccompanied homeless youth, requiring department approval for extensions, while allowing longer stays if a parent arranges return. It revises key terms like "homeless person," "HOPE center," and "street outreach services" to clarify program eligibility and operations. These changes aim to standardize definitions across state agencies and align with existing homelessness housing frameworks without introducing new funding or major program shifts.

Senate Bill 5613 aims to establish clear and objective standards for residential development across Washington state. It requires cities and counties to adopt these standards for residential projects by January 1, 2028, ensuring regulations do not create unreasonable costs or delays. The bill directs the Department of Commerce to form a stakeholder work group to analyze development barriers and suggest model codes. While promoting objective standards, it allows for an alternative approval process based on aesthetics, provided developers retain the option of using the clear and objective standards. These provisions apply to residential development within urban growth areas.

SB 5587 mandates that the Washington center for real estate research produce biennial reports, starting in 2026, analyzing existing housing units and needs across various income levels in each county. These reports will track each county's progress in addressing housing gaps and meeting emergency housing needs. The bill also amends the Public Works Board's criteria for financial assistance. It requires the board to prioritize public works projects that promote infill development or increase affordable housing in counties identified in these reports as having a gap between existing housing and housing needs.
