Yes, it can be possible to convert a garage or shed into an ADU. Please submit a planning application with all the materials stated in the application checklist for ADUs for the application to be considered. The Planning Division will review the conversion application for compliance with Richmond and California ADU law. It is recommended to reach out to the Building Division for Building Code requirements for conversions, as the structure will need to comply with habitable space and safety requirements that may not have been required when the garage or shed was built.
