What to do
1. Check if your project qualifies for this application
We accept applications for ADUs and work related to ADU construction like:
- Expansions required for an ADU
- Excavations required for an ADU
- New construction for a detached ADU
- Interior remodel work to create independent access to the ADU
Do not use this application if your project includes:
- New construction of a single-family home
- New construction of a multi-unit building
- Expansion of existing building
- New construction of a separate building
- Demolition of an existing structure to make room for an ADU
For those projects, see instructions from the Department of Building Inspection.
Do not use this page for unit legalization or new construction of more than an ADU. If your project includes demolition, you will also need to follow the in-house review process with the Department of Building Inspection.
2. Gather your project team information
We will ask you for:
