This bill amends existing zoning regulations for commercial, retail, and mixed-use areas in cities and code cities in Washington State. It introduces a new section to chapter 36.70A RCW, mandating that cities allow the addition of housing units in ground floor commercial or retail spaces within designated station areas, with specific limitations on the designation of major pedestrian corridors. The bill also provides an expedited process for developments to deviate from street-level use standards if it would facilitate the creation of more housing units. Additionally, it defines "station area" and outlines the criteria for its designation based on proximity to public transit.

Furthermore, the bill amends RCW 35.21.990 and RCW 35A.21.440, prohibiting cities from imposing certain restrictions on housing density, parking requirements, and design standards for existing buildings used for residential purposes. It requires cities to adopt zoning regulations that promote greater building height and density for developments utilizing mass timber products. The bill also clarifies that existing buildings must have received a certificate of occupancy at least three years prior to the permit application for adding housing units, ensuring that safety standards are met while facilitating housing development.
