Types of ADUs Allowed
Attached ADU
An attached ADU is one that is attached to your house. Also know as Addition ADUs or “bump-out ADUs. These types of ADUs can be accessed from the primary house with a door in the connection point, but also can be independent of the main home.
Detached ADU
A detached ADU is not connected to your primary house. The dwelling needs to be within your property setbacks and allowable building size (both height and square footage).
Junior ADU
Junior Accessory Dwelling Units (JADUs) are named this way because they are small (up to 500 square feet).
In California, the recent state bills
AB68 and
AB 881 permits both an ADU and a Junior ADU (JADU) on the same lot with a proposed or existing single-family dwelling. This means you can have two units on your lot: ADU, and JADU.
