The bill seeks to enhance community and transit-oriented housing development in Washington State by amending existing laws and introducing new provisions that align land use policies with state investments in mass transit. It emphasizes the creation of vibrant urban environments that prioritize affordable housing and community facilities while providing technical assistance to cities to maximize the benefits of transportation investments. Key amendments include a clear definition of "affordable housing" as housing costs not exceeding 30% of a household's monthly income, along with new terms such as "active transportation," "middle housing," and "green infrastructure." The bill also clarifies the definition of "major transit stop" and includes provisions for emergency and permanent supportive housing.

Additionally, the legislation mandates that cities planning under RCW 36.70A.040 allow multifamily residential housing in station areas and set minimum floor area ratios for developments. It prohibits off-street parking requirements for residential and mixed-use developments in designated station areas, except for accessible and short-term delivery parking. The bill introduces a 20-year tax exemption for properties near high-capacity transit with affordability commitments and requires annual reporting on compliance with affordable housing standards. It also establishes new guidelines for impact fees, ensuring that low-income housing projects receive exemptions and reductions. Overall, the bill aims to promote higher density housing near transit stations while ensuring affordability and addressing the needs of vulnerable populations.
