Parking Requirements and Affordable Housing
How can developers of low- and mixed-income housing convince local officials to reduce minimum parking requirements?
Developers of low- and mixed-income housing nationwide often find themselves hamstrung by local requirements for minimum parking allotments. By mandating a minimum amount of parking, local governments often require the production of significantly more parking than residents actually need. This reduces the amount of housing that can be produced on a given site, limits additional amenities that could otherwise be provided and unnecessarily increases the cost of housing.
