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 mass transit investments. It emphasizes the creation of affordable housing options and vibrant urban environments, while providing technical assistance to cities for effective planning. Key amendments include a revised definition of "affordable housing," which stipulates that monthly housing costs should not exceed 30% of a household's income, and introduces new terms such as "active transportation," "middle housing," and "green space." The legislation also clarifies criteria for "major transit stops" and establishes definitions for "urban growth areas" and "vulnerable populations," aiming to foster an integrated approach to housing and transportation.

Additionally, the bill mandates that cities planning under RCW 36.70A.040 allow multifamily housing in station areas and sets minimum floor area ratios for new developments. It reduces parking requirements for residential and mixed-use developments in designated station areas, allowing exemptions for certain projects from environmental review. The legislation also introduces tax exemption options for multifamily housing projects near high-capacity transit, with specific affordability commitments and tenant relocation assistance. Furthermore, it outlines requirements for property owners applying for tax exemptions and mandates annual reporting to ensure compliance with affordable housing standards. Overall, the bill aims to facilitate affordable housing construction and promote sustainable urban growth in alignment with transit infrastructure.
