Parking minimum

United States

• On July 21, 2022, Oregon's Land Conservation and Development Commission, a board of the Oregon Department of Land Conservation and Development, passed a set of rules prohibiting Oregon's eight largest metropolitan areas (spanning 48 cities and 5 counties, accounting for two-thirds of the state’s population) from mandating parking minimums within a half-mile of frequent transit, for homes of 750 square feet or less, or for homes meeting affordability targets.
• In September 2022, the U.S. state of California passed AB 2097, which includes a ban on parking minimums for buildings within 1⁄2 mile (0.80 km) of public transit.
• In May 2024, Colorado passed HB-1304, which eliminates and prohibits parking mandates for most multifamily residential properties within a metropolitan planning organization within a quarter mile of a transit stop or station after June 30, 2025, with an exception for multifamily properties of more than 20 units.
• In May 2025, Washington passed Senate Bill 5184 (the Parking Reform and Modernization Act), which caps the minimum parking requirements that cities and counties impose on new development to 0.5 spaces per residential dwelling unit and two spaces for every 1,000 square feet of commercial space. It also prohibits cities from requiring any off-street parking spaces when issuing permits for certain uses, including affordable housing, senior housing, and child care facilities.
• On November 26, 2025, Connecticut HB 8002 was signed into law, prohibiting local governments from enforcing parking minimums on residential developments with fewer than 16 homes, while requiring developments with more than 16 homes to submit a parking needs assessment. In addition, the law allows any municipality to create up to two “conservation and traffic mitigation districts” (covering a combined total of no more than eight percent of the municipality’s land area) where a town can extend parking minimums to development of less than 16 units. Finally, the law allows municipal planning and zoning commissions to adopt regulations allowing applicants subject to a minimum parking requirement to pay a fee instead of providing the required parking spaces in commercial developments and residential or mixed-use developments with at least 16 dwelling units. It was the first statewide parking mandate preemption signed into law east of the Mississippi River.
• In December 2025, Illinois SB 2111 (including the Illinois People Over Parking Act) was signed into law, prohibiting local governments from enforcing parking minimums on any development project within one-half mile of a public transportation hub or one-eighth mile of a public transportation corridor.
