Reduced Parking Requirements

At a Glance

Where tool is used: Residential neighborhoods (in case of second units) and downtowns/transit corridors
Timeline: Medium-term
Who implements: Jurisdictions
Relative density impact: Medium (can increase number of units developed)

Whether in surface lots, below-ground lots, or in parking structures, parking is expensive to build and maintain, and consumes significant amounts of land. Required parking minimums on residential development, especially in downtowns and transit corridors, where land is more expensive, drive up construction costs, increase market-rate rents, and decrease the amount of housing produced.1 Furthermore, residential parking in mixed-use districts is often significantly oversupplied, with a third or more of spaces in parking lots sitting empty.2

Faced with required parking minimums for housing, developers may be forced to build less housing than they would otherwise, since parking increases construction costs. They are also likely to bundle parking and housing costs, driving up the rents of market-rate units and forcing residents without cars to still pay for parking.

Parking requirements can also reduce the variety of housing stock by making it difficult to build particular types of housing on particular sites. In particular, parking minimums can hinder affordable housing projects in urban centers or near transit—even though residents of affordable housing in these locations are less likely to own one or multiple cars—because subsidy programs do not account for the combined higher land and parking costs.3

Some cities are changing their policies to allow developers to “unbundle” parking from housing development. This can take a variety of forms:

  • Forgoing off-street parking requirements completely in higher-density areas with transit, jobs, and services nearby
  • Providing parking off-site in existing lots or on parcels not suitable for housing development
  • Charging residents who use parking a monthly fee for their space
  • Providing a “cash out” to residents for their unused spaces
  • Facilitating other transportation options, for example, through subsidized transit passes, secure bicycle parking, or carsharing spaces and subsidies

The following cities in San Mateo County have passed some form of reduced parking requirements:

  • Brisbane
  • Burlingame
  • Colma
  • Daly City
  • East Palo Alto
  • Foster City
  • Hillsborough
  • Menlo Park
  • Millbrae
  • Pacifica
  • Redwood City
  • San Carlos
  • San Mateo
  • South San Francisco

  • Reducing off-street parking requirements for multifamily properties reduces development costs and enables developers to build more units.
  • Relaxed parking requirements remove a major barrier to building transit-oriented developments, affordable housing, and other multifamily housing projects.

icon_community-orange Community Considerations

  • Reducing parking requirements does not mean developers won’t supply any parking. Developers will respond to demand for dedicated off-street parking from potential renters and buyers.
  • However, relaxed requirements allow developers to supply the amount of parking they think is appropriate, in a way they think is best, whether that’s one space per unit instead of two, or providing parking in an offsite lot.4
  • Reduced residential parking minimums should be paired with traffic reduction measures, such as subsidized transit passes or carsharing spaces.

icon_engage-orangeCommunity Engagement Strategies

  • Educate your community: Proactively address concerns about parking spilling over into residential neighborhoods by meeting with home owner associations and neighborhood groups.
  • Engage your community: Have a residential community that offers a transportation demand management program give presentations on benefits offered, participation of residents, and reductions in vehicle miles traveled.
  • Promote success stories: Highlight residents of developments with reduced parking requirements.
