The bill aims to reform minimum parking requirements across various jurisdictions in Washington State, addressing the negative impacts of excessive parking mandates on development costs, public health, and environmental sustainability. It establishes new regulations that limit parking requirements to a maximum of 0.5 spaces per multifamily dwelling unit and one space per single-family home, as well as two spaces per 1,000 square feet of commercial space. Additionally, it eliminates minimum parking requirements for certain categories, including affordable housing, senior housing, and small commercial spaces, while allowing cities and counties to request variances under specific conditions.

The legislation also mandates that the state building code council research and potentially update accessible parking space requirements to reflect current disability rates among drivers. Furthermore, it repeals existing laws related to minimum residential parking requirements and sets implementation timelines for cities and counties based on their population size. The act is officially titled the "Parking Reform and Modernization Act."
