Converting Garages into Housing

Cities have a large supply of garages that could be converted into affordable housing in single-family neighborhoods, but minimum parking requirements prevent converting most of these garages into apartments. We examine how cities can relax off-street parking requirements for houses with converted garages. In Residential Parking Permit Districts, cities can limit the number of on-street parking permits allowed at any address with a second unit. This policy can remove on-street parking congestion as a reason for neighbors to oppose garage conversions, double the potential number of housing units in single-family neighborhoods, and increase the supply of safe, affordable housing.
