Housing (Property Development)

This bill requires cities to review residential housing permit applications under the zoning rules in effect when a fully completed application is submitted, rather than current rules. It allows cities to pause processing until fees are paid or notices are posted, but does not make applications invalid for missing these items. The law applies to projects in urban growth areas and does not override other requirements like those in chapter 43.21C RCW. It standardizes the timing for permit reviews to reduce delays in housing development.

SB 5747 exempts affordable housing projects from current state building code requirements, allowing cities and counties to enforce older building codes (the last four iterations) to lower construction costs and speed development. It directly affects developers and local governments building housing defined as affordable - rental units costing ≤30% of household income or owner-occupied housing for low/moderate-income households (≤80% of local median income). The bill amends Washington’s building code statutes (RCW 19.27 and 19.27A) to create this exemption specifically for affordable housing projects. This policy change aims to increase housing supply by reducing regulatory barriers for qualifying developments.

HB 1840 authorizes counties to allow "middle housing" (like duplexes, triplexes, or townhouses) in designated unincorporated urban growth areas, specific rural development zones, and established communities. It requires at least one middle housing unit per single-family lot in urban areas and limits these developments to four units per lot in rural zones. The bill mandates that counties apply the same zoning, permit, and environmental rules to middle housing as to single-family homes, while requiring sewer service for rural middle housing. This policy aims to increase housing density without new infrastructure, directly affecting homeowners and developers in targeted areas.

HB 1687 clarifies definitions and expands support mechanisms for social housing public development authorities in Washington State. It defines "social housing" as publicly owned rental housing available to all income levels (low, moderate, and high-income households) with cross-subsidized rents, and establishes specific income thresholds based on HUD data. The bill enables state and local governments to provide property, infrastructure, or funding to these authorities without standard bidding requirements, while requiring five days of public notice for such transactions. It directly affects social housing authorities, state/local governments, and residents of subsidized housing projects across Washington. The legislation focuses on structural changes to housing authority operations, not on new funding or outcomes.

SB 5755 incentivizes converting underutilized commercial properties into residential housing by creating a state review process for eligible projects. It requires property owners to submit detailed proposals by October 1, 2025, including location details, infrastructure needs, and affordability plans. Eligible projects must be in urban areas with at least 250 new units, avoid sensitive zones or historic sites, and score high on criteria like low-income housing, environmental features, and community benefits. High-priority projects receive streamlined permits (processed within 180 days), technical assistance, and priority for state funding to accelerate development. This directly affects developers and property owners seeking to redevelop commercial sites into mixed-income housing near transit and jobs.
