Accessory dwelling units
ADU guides for San Diego County
A converted garage may be planned as a room connected to the home or as a separate dwelling. These guides focus on ADU and junior ADU questions, including how to check applicable state and local requirements for your property.
Terms such as granny flat and casita can describe different spaces. Ask the reviewing agency which classification applies to the layout and use you propose.
