As of May 2025, Washington’s Parking Reform and Modernization Act (SB 5184) sets clear limits on how much parking local governments can require in new developments. In most cases, it shifts the decision-making power away from blanket local quotas and back to property owners, allowing them to determine how much parking makes sense for the homes or businesses they want to build. Additional exemptions apply to childcare centers, subsidized affordable housing, senior housing, and existing buildings changing use—all of which now have the flexibility to build only the parking they actually need.
