Most US cities require developers to include a certain number of off-street parking spaces when building new housing. Few planning practices do so much harm to cities: Parking mandates induce more driving, increase housing costs, and put climate goals out of reach. Recognizing the damage inflicted by mandatory parking minimums, cities including Minneapolis, Hartford, and Sacramento have recently abolished them entirely or within walking distance of transit stops.
San Diego is the most recent city to substantially reduce its parking mandates. In March, the City Council passed a law eliminating parking requirements downtown and within a half mile of major transit stops citywide. The change will eliminate regulations that added as much as $90,000 to the cost of building one apartment, making it easier to add more affordable homes near transit.
