What are ADUs?
The State of California defines an ADU or “accessory dwelling unit” as a self-contained, residential unit located on the same lot as an existing single-family home.
An ADU is smaller in size and must include all of the amenities found in a primary dwelling: a kitchen, bathroom, sleeping area, and storage.
An ADU must also conform to all State and Local City and Planning code requirements, as well as energy and building code requirements established by California Title 24 Building Energy Efficiency Standards and Housing and Community Development CALGreen compliance.
ADUs are also known by many names: granny flats, in-law units, backyard cottages, secondary units, and more.
