American cities have a large supply of garages that could be converted into affordable apartments, but off-street parking requirements often stand in the way. If a home owner wants to convert a two-car garage into an accessory dwelling unit (ADU), she typically must replace the garage parking spaces with two new off-street parking spaces, plus an additional off-street parking space for the new unit. While some cities have eliminated off-street parking requirements for ADUs, this is often not enough to remove the barrier or address the concerns of neighbors.

This edition of Zoning Practice details a proposal for zoning reforms to facilitate garage-to-apartment conversions. It acknowledges the potential neighborhood impacts of eliminating parking minimums and posits a market-based solution.
