ADU guide
ADU Parking Requirements
A garage conversion changes where a household can park. State and local rules, the type of project, and the property can affect the review, so confirm the current requirements before committing to a layout.
Requirements depend on your property and the agency reviewing it. Confirm current details with that agency before finalizing plans.
Questions to consider
- Identify the parking and driveway you use today
- The City of San Diego ADU guidance lists conditions involving the Beach Impact Area and transit priority areas; confirm whether the mapped property and the specific project meet those conditions.
- The City also describes circumstances in which a driveway may need to close; ask the agency to assess the existing driveway and proposed work.
- Ask the reviewing agency how the proposed use affects parking
- For City of San Diego property, check its published ADU parking and driveway guidance
- Discuss any proposed exterior or driveway changes with the designer

Common questions
Will I have to replace a garage parking space?
The answer depends on the applicable rules and property. The City of San Diego describes parking and driveway conditions on its ADU page; ask the reviewing agency about your address.
Can I keep my driveway?
Do not assume the outcome. Ask the reviewing agency whether the proposed conversion affects the existing driveway.
