SB 5733: Concerning updating comprehensive plans.

This bill requires Washington counties and cities to regularly review and update their comprehensive land use plans, with specific deadlines for compliance. It allows small cities (under 500 residents, not near large cities, with low growth) to skip full plan revisions but still mandates updates to critical area and housing regulations. The law aims to accelerate housing development by streamlining local planning processes, directly affecting all local governments and housing projects. Key changes include standardized review schedules, exemptions for small communities meeting criteria, and requirements to align plans with population forecasts and housing needs.

SB 5659: Eliminating each local government's proportional share of Washington's housing shortage.

This bill requires Washington counties, cities, and towns with authority to approve new home construction to permit enough housing to cover their portion of the state's estimated 1 million+ housing shortage by 2035. The Department of Commerce will calculate each local government's specific housing target by April 2026 and publish it online. Local governments must review their zoning and permitting rules to remove barriers to construction, and if over 33% of building permits are denied, they must address the causes. The bill also establishes a process for local governments to report state laws hindering housing, prompting the legislature to consider amendments.

HB 1235: Ensuring compliance with the housing element requirements of the growth management act.

HB 1235 requires Washington counties and cities to submit housing elements and development regulations to the state Department of Commerce for compliance review before they take effect. Jurisdictions must submit applications within 10 days of amendments or by six months after comprehensive plan updates, with the department issuing a final compliance decision within 90 days. The bill establishes a public compliance list showing each local government’s submission status and review outcome, and prohibits denying affordable housing projects without meeting specific conditions, such as having a state compliance determination. This directly affects all local governments required to plan under the Growth Management Act, ensuring their housing plans align with state laws on affordability, environmental standards, and zoning.

HB 1010: Authorizing accessory dwelling units in rural areas.

HB 1010 allows rural counties in Washington to authorize detached accessory dwelling units (ADUs) - small secondary homes on the same lot as a primary residence - on any lot size, even where local zoning previously prohibited them. Key requirements include limiting ADUs to 1,296 square feet, ensuring water/sewage systems can handle added demand, prohibiting construction on closed water sources or agricultural land, and requiring exterior design to match the main home. The bill directly affects rural property owners seeking to build affordable housing options and counties managing land use planning. It aims to expand housing choices without counting new residents toward rural growth targets in county plans.

SB 5604: Promoting transit-oriented development.

SB 5604 creates a 20-year property tax exemption for new housing projects located within a designated "station area" (within 0.5 miles of a major transit stop) in Washington. To qualify, projects must include at least 20% of units affordable to low- or moderate-income households (defined as 50-80% of local median income) for 50 years, with long-term covenants ensuring affordability. Local governments must adopt regulations for station areas and oversee compliance, including recording deeds to maintain affordability. The bill aims to incentivize housing near transit by reducing development costs while mandating long-term affordability for residents.

HB 1183: Concerning building code and development regulation reform.

HB 1183 reforms building codes and development regulations for cities and counties in Washington to encourage affordable and sustainable building practices. The bill mandates that cities allow for increased housing density, reduced parking requirements, and streamlined permitting when adding residential units within existing commercial or mixed-use buildings. It also provides flexibility in setback and roof height rules for existing buildings undergoing residential retrofits and for new construction or retrofits meeting "passive house" energy efficiency standards. These changes aim to reduce regulatory barriers for converting existing structures into homes and promote energy-efficient construction.

SB 5559: Streamlining the subdivision process inside urban growth areas.

Senate Bill 5559 aims to streamline the process for dividing land into multiple parcels within urban growth areas in Washington State. The bill allows counties, cities, and towns to increase the maximum number of lots permitted in a "short subdivision" - a simplified land division process - from four to up to nine, provided these divisions are within an urban growth area and the local government passes an ordinance. This change primarily affects landowners and developers by potentially making it easier to subdivide property. Additionally, the bill updates definitions related to subdivisions and adjusts regulations regarding further division of short plats within a five-year period.

SB 5529: Amending the county population threshold for counties that may exempt from taxation the value of accessory dwelling units to incentivize rental to low-income households.

Senate Bill 5529 amends the county population requirements for jurisdictions that can offer property tax exemptions on accessory dwelling units (ADUs). It lowers the minimum population threshold, allowing counties with populations between 900,000 and 1,500,000 to also exempt ADUs from taxation. This aims to incentivize homeowners to rent these units to low-income households, provided conditions like tenant income verification and rent limits are met. For these newly eligible counties, the exemption specifically applies to detached ADUs and requires a local legislative authority resolution.

SB 5332: Concerning mobile dwellings.

SB 5332 allows cities and counties in Washington to permit at least one mobile dwelling unit (like tiny homes on wheels, travel trailers, or RVs) on residential lots that already have a home, are in urban growth areas, and have adequate utility capacity. It requires safe utility connections (water, sewer, electricity) to existing homes on the lot and bans homeowners' associations from prohibiting these units, though the rule expires in 2028. The bill does not require new construction but sets standards for how mobile dwellings must be connected to utilities and maintained to remain movable. This directly affects local governments, property owners with existing homes, and HOAs in qualifying areas.

HB 1859: Expanding opportunities for affordable housing developments on properties owned by religious organizations.

HB 1859 allows Washington religious organizations to develop affordable housing on their properties with increased density allowances. To qualify, at least 50% of units must be permanently affordable for low-income households (earning at or below 80% of local median income) for 50 years, with no discrimination based on protected characteristics. Religious organizations must cover all development fees and costs, and local governments must approve such projects if requested. This applies to new construction and rehab projects on religiously owned land, amending zoning laws to support affordable housing expansion.
