Garage Conversion in Coronado
Planning a high-end garage conversion in Coronado? Coronado has compact, high-value lots, many with older homes and alley access, so attached units and garage conversions are common options. Proactive Edge Developments is a CSLB-licensed San Diego County general contractor. We convert garages end to end, handle the City of Coronado permit process, and include a free 3D rendering so you see the result before we start.
Permits for a garage conversion in Coronado
Coronado regulates ADUs under Municipal Code 86.56.105, requires a separate ADU application, and runs a Pre-Approved ADU Program. Source: City of Coronado, Coronado Municipal Code 86.56.105.
Coastal Zone: parts of Coronado are inside the California Coastal Zone. Projects there can need a coastal development permit on top of the building permit, which adds review time. We check your parcel before design starts.
State timeline: when there is already a home on the lot, California law (Gov. Code §66317) requires the city or county to approve or deny a complete ADU application within 60 days.
We prepare the plan set, submit it, answer plan-check corrections, and schedule every inspection through final sign-off.
What your Coronado garage conversion includes
- Garage-to-ADU conversions. Convert your existing garage into a fully permitted, rentable accessory dwelling unit at a fraction of new-build cost.
- Lower cost, faster build. Because the structure exists, garage conversions are typically the most affordable path to added square footage in San Diego.
- Code-compliant & permitted. We handle egress, fire separation, utilities, and all San Diego permitting requirements for a legal conversion.
- Free 3D rendering. Visualize your converted space before construction begins — included free for every new client.
Featured project: the Curlew St lot split
At 3680–3682 Curlew St in San Diego, we added a second story to the main house and converted the garage into a separate unit. The owner now has two rentable addresses on one lot. It's the project we point Coronado homeowners to first, because it shows our permitting, structural, and finish work in one place.
