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.

HB 2442 allows Washington counties and cities to impose specific real estate excise taxes to fund local capital projects and affordable housing. It authorizes a 0.25% tax on real property sales for general capital projects (like streets, parks, and sewer systems), with strict usage rules requiring projects to align with comprehensive plans. Additionally, it creates a separate 0.5% tax exclusively for affordable housing development, including acquisition, construction, and maintenance for low- and moderate-income residents. Local governments must document funding plans for future projects and follow voter approval processes for new taxes, while funds must be managed through competitive grant processes for housing initiatives. The bill directly affects local governments by expanding their tax tools for infrastructure and housing priorities.

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 5576 allows counties, cities, and towns in Washington State to impose a new special excise tax of up to four percent on short-term rental lodging booked through online platforms. The revenue collected from this tax must be used exclusively for essential affordable housing programs. These funds can support activities such as acquiring, rehabilitating, or constructing affordable housing, covering operations and maintenance costs for such housing, or providing rental assistance to tenants. Local governments are required to publish an annual report detailing how these tax revenues were spent.
