In the U.S., there are more homes with three-car garages being constructed than there are one-bedroom apartments.
Many cities have a huge, untapped source of affordable housing: garages.
A professional estimate, indicate about 400,000 single-family homes in Los Angeles have a two-car garage that could be converted into an apartment. Until recently, Los Angeles prohibited most such conversions, but in 2017, California enacted a law that overrides local prohibitions and allows almost any homeowner to convert their garage into an accessory dwelling unit (ADU).
