Can you build a tiny house in your backyard in california

If you're building a tiny house on a foundation, you'll need building permits. For a tiny house on wheels, you'll need to have the home inspected and registered with the California DMV.

In California, homeowners have the option of constructing an accessory dwelling unit (ADU) or a backyard cottage on their property. An ADU may be a fantastic way to increase living space while also providing a source of income as a separate dwelling.

In the counties of Alameda, Contra Costa, Lake, Mendocino, Napa, Sacramento, and Sonoma, tiny houses on wheels are allowed as “caregiver dwellings”. This means that the tiny house has to be in the backyard of someone who needs constant assistance from the owner of the tiny house.

Property requirements. A guest house may be permitted only on properties in A-1 and R-1 zones which contain an existing owner-occupied single family detached dwelling unit. Only one guest house may be permitted per lot of record.
