Municipal ADU regulations adopt California state laws to some great extent, but still have ordinances of their own, differentiating ADU regulations from city to city

Functionally, a Standard ADU generally includes living, sleeping, kitchen and bathroom facilities, and a separate and lockable entrance door. However, a JADU (which stands for Junior ADU) is not required to have a dedicated bathroom.

Types of ADU

There are several different types of ADU

Detached ADUs are basically free-standing, newly-built structures in the backyard.

Attached ADUs are additions to the primary house. They are basically the same as a detached ADU, but they were constructed next to a house with shared wall or roof.

Garage converted ADUs, are existing garages that are converted for use. The garage may be attached to the house or detached.

Other internal conversions are existing non-livable spaces converted to ADU, such as basements, attics, hallways, boiler rooms, etc., mostly seen at multi-family houses.
