Yes, a two-story ADU can be built in Laguna Beach. However, it must comply with the maximum height restrictions:
- Detached ADUs: Maximum height of 16 feet, or 18 feet if the property is within one-half mile of a major transit stop or high-quality transit corridor.

Can you convert a garage into an ADU or add an ADU on top of a garage in Laguna Beach?
Yes, it is possible to convert an existing garage into an ADU, or even add an ADU on top of a garage, as long as the conversion meets the required setbacks, size limitations, and other zoning requirements. The ADU must also have independent access and be compliant with health and safety codes.
What are the parking requirements for ADUs in Laguna Beach?
Parking requirements for ADUs in Laguna Beach are generally waived if the property is within one-half mile of a major transit stop or a high-quality transit corridor, such as Laguna Beach Transit. If the property is not within walking distance of transit, one parking space may be required for the ADU.
What is the average time of the permitting process in Laguna Beach?
The permitting process for ADUs in Laguna Beach typically takes 60 days from the submission of a completed application. However, this timeframe can be extended if the application involves deviations from the city’s objective standards or requires discretionary review. If the city denies the permit, it will provide a detailed explanation outlining the reasons for denial and instructions on how to remedy the deficiencies.
