Lewis Mumford was suspicious of parking. “The right to access every building in a city by private motorcar,” he wrote in The City in History, “in an age when everyone owns such a vehicle, is actually the right to destroy the city.” Jane Jacobs, who disagreed with Mumford on many counts, agreed here. Parking lots, she said in The Death and Life of Great American Cities, were “border vacuums”: inactive spaces that deadened everything around them.
Mumford and Jacobs published those lines in 1961, when most United States cities were 15 years into an experiment called “minimum parking requirements”: mandates in zoning codes that forced developers to supply parking on-site to prevent curb congestion. In postwar America, development was booming, and neighbors were worried that new residents would make street-parking impossible. Decades later, parking requirements still exist nationwide. In Los Angeles, where I live, new apartment buildings must have at least one parking space per unit; retail buildings need one space per 300 square feet; and restaurants need one space for every 100 square feet of dining area.
Parking requirements enforce what Mumford decried: the right to access every building by private car. As Mumford predicted, they have been a disaster. American urban history is stained with tragic missteps and shameful injustices, so parking requirements are hardly the worst policy cities have tried. But they are notable for how much needless damage they have caused, over a long period, with few people even noticing.
