Inland coastal, 75-90°F summers, mild winters, 12 in/yr rain, covenant-protected landscaping. North County Inland properties in Vista, San Marcos, Escondido, and Carlsbad include a high concentration of older tract homes with detached two-car garages that are well-suited for full ADU conversions.

A full accessory dwelling unit conversion turns an attached or detached garage into a legally permitted, self-contained living space with its own kitchen, bathroom, and entry under California ADU law. In Rancho Santa Fe the same work goes by several names, including garage ADU, ADU construction, ADU construction cost, detached ADU, backyard ADU, granny flat conversion, or casita conversion, and the permitting path is the same for all of them.

A full ADU conversion in San Diego County typically runs $75,000-$150,000 depending on the garage size, finish level, structural requirements, and whether a panel upgrade is needed. Permit fees vary by city. The licensed pro you hire confirms the written price. Garage Convert SD sets no prices.

Yes. A full ADU conversion requires building permits, architectural drawings, Title 24 energy compliance documentation, and plan check approval from your city or county. California law has streamlined the ADU permit process and limits permit fees, but permits are still required. The crews we refer handle all permitting when the scope calls for it.

Yes. Detached garages are one of the most common ADU conversion types in San Diego County. California law allows detached garage conversions on most single-family lots regardless of lot size, subject to setback and height rules specific to your property. The licensed pro you hire confirms eligibility from the property and the reviewing department.

Yes, the garage parking space becomes living space. However, California law bars local agencies from requiring replacement parking when a garage is converted to an ADU, whether attached or detached. The City of San Diego still lists a Beach Impact area exception outside transit priority zones. For coastal parcels, confirm the current rule with Development Services.

There is no single published timeline for a full ADU conversion. State law gives the agency 60 days to approve or deny a completed application, and that clock starts once the application is complete, not at first submittal. It is a permit decision deadline, not a construction schedule or an approval guarantee. After permits are issued, the licensed pro sets the project timeline from the approved plans and the site conditions.
