Housing (Affordable Housing)

SB 5591 creates a local sales and use tax reimbursement program for developers building affordable housing projects. It allows cities or counties to adopt programs that reimburse developers for sales taxes paid on construction materials, provided the project includes at least 50% units affordable to low-income households (costing ≤30-38% of income) for 40 years. Developers must apply to local governments, meet strict affordability and timeline requirements (completion within 3 years), and maintain affordability for the full 40-year period. The program applies only to projects meeting Washington’s defined "affordable housing" standards and requires local government approval before implementation.

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.
