Are you planning on building an accessory dwelling unit (or ADU) in Alameda? Here’s what you need to know before you build.
ADUs are created via the following methods:
- Building a new detached structure
- Converting an existing, legally constructed structure
- Building an addition to your home
- Converting space in the primary dwelling like a basement
- Creating a junior ADU which is created entirely within the space of your home
If your plans include demolishing a structure, you will need a building demolition permit. If the building was built before 1942, you will also need a Certificate of Approval from the Permit Center.
To build an ADU in Alameda, you’ll need to apply for an ADU permit from the building division at the Permit Center. If needed apply concurrently for:
- Solar
- Electrical main panel upgrade
- New electrical meter
- Encroachment permits
You will need the following documents when you apply for a building permit for an ADU. The ADU zoning checklist is available at the Permit Center online in Alamada.ca.gov.
- Plans of the proposed ADU
- Certificate of approval for demolition of a pre-1942 structure
- For junior ADUs you may also need to complete a declaration of restrictions form from the Alameda County Clerk’s record office.
Once your permit is issued, you can begin construction. When building inspections are completed, you will receive a Certificate of Occupancy.
If you have any questions about this process or how to build an ADU in Alameda, look for the updated ADU handout available online in the Permit Center at Alamedaca.gov.
