1955: San Francisco established its first residential parking space requirements of one space for each newly created dwelling unit.

The legislation banned new driveways on Market Street, and restricted new driveways on other important walking, cycling, and transit routes in the downtown. Citywide, it established minimum residential bicycle parking requirements (.5:1) and car-share requirements in larger projects. The amendments allowing parking on upper floors under specific conditions were added after a mayoral veto of the first piece of legislation.

Eisenhower-era parking requirements still prevail across most of San Francisco, but the city's most recent plans and policy changes are embracing new thinking about the role of reduced parking in creating livable and sustainable cities. The 1970's saw the emergence of the environmental, historic preservation, and livable streets movements that offered a strong critique of automobile dependence. The opening of BART in 1973 provided the impetus for limiting commuter parking in San Francisco's growing downtown, which resulted in the first parking limits as part of the city's Downtown Plan.

Most of the reductions in parking requirements have occurred over the last decade. Between 1968 to 1997, every neighborhood in the city had a minimum residential parking requirement, no neighborhood had a residential maximum, and only one neighborhood (downtown) placed an upper limit on the amount of non-residential parking. By mid 2011, a broad swath of the city, reaching from Downtown into SoMa, Chinatown, Telegraph Hill, Mission Bay, Tenderloin, Hayes Valley, Duboce Triangle, and parts of the Mission and Potero Hill, has no minimum parking requirements.

In addition to reducing parking requirements, the city has developed a toolkit of complementary development requirements to reduce automobile dependence, including unbundling parking costs from housing costs, bicycle parking requirements, and requiring car share spaces in large new developments.
