What Is a Backyard ADU?
A backyard ADU (Accessory Dwelling Unit) is a secondary residential structure built on the same lot as a primary home. These standalone units are fully functional living spaces that typically include:
- A bedroom or sleeping area
- Kitchen or kitchenette
- Bathroom
- Living space
- Separate entrance
Unlike traditional home additions, a backyard ADU functions as an independent dwelling while remaining on the same property as the main residence.
California’s evolving housing regulations have made ADU construction more accessible than ever, encouraging homeowners to create additional housing while increasing property value.

Increased Property Value
