What is an ADU (accessory dwelling unit)?
Quick Answer
An ADU is a secondary self-contained living unit — kitchen, bath, sleeping area — on the same lot as a primary residence. Forms include detached cottages, garage conversions, basement units, and attached additions. Most U.S. states now allow ADUs.
