This bill amends existing zoning regulations for cities and code cities in Washington, specifically focusing on commercial, retail, and mixed-use areas. It introduces a new section to chapter 36.70A RCW that mandates cities to 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. Additionally, it provides an expedited process for developments to deviate from street-level use standards if such deviations would lead to an increase in housing units. The bill also 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 facilitate greater building height and density for developments utilizing mass timber products. The bill also clarifies that cities cannot deny building permits for housing additions based on nonconformity with existing regulations unless significant detriment to the surrounding area is demonstrated. Overall, the legislation aims to promote housing development in urban areas while maintaining certain health and safety standards.
