The bill amends RCW 43.21C.229 to establish categorical exemptions for multiunit housing development within incorporated areas in urban growth areas under the State Environmental Policy Act (SEPA). It allows cities and counties to exempt certain government actions related to residential, mixed-use, or commercial developments up to 65,000 square feet, provided these developments align with the density and intensity goals of their comprehensive plans. The bill specifies that local governments must consider probable adverse environmental impacts and ensure these are addressed through existing regulations or plans. Additionally, it mandates that environmental analyses include transportation impacts and require consultation with relevant stakeholders.

Key changes include extending the categorical exemption to projects proposing to develop two or more residential or middle housing units in cities with populations of 700,000 or more until September 30, 2028, and to projects developing four or more attached units in urban growth areas until September 30, 2027. The bill clarifies that these exemptions do not waive other state or local development regulations and requires notification to impacted federally recognized tribes. Overall, the bill aims to facilitate housing development while ensuring environmental considerations are met.
