ADU Services in Coronado, CA.

Homeowners along Alameda Boulevard, in the Coronado Cays, and throughout The Village are building ADUs for a straightforward reason: this island has almost no rental inventory and enormous demand. Navy families rotating through NAS North Island need housing that doesn't exist at scale. Adult children priced out of a market where median home values sit near $1.8M need a place to land. And multigenerational families who already own here want to keep their parents close without sacrificing privacy. ADUz, designer Alma Sanchez and licensed build partner The Rock Remodel (CA 1042918), handles design, permits, and construction on the island. We know Coronado's historic preservation expectations, its city jurisdiction quirks, and the kind of housing stock that actually shapes what you can build here.

Coronado is its own city, not unincorporated San Diego County, so permits run through the City of Coronado's planning department rather than the county. That matters because the city has a strong historic preservation culture, particularly in The Village where Victorian and Craftsman homes from the early 1900s sit on lots that may carry design review requirements. An ADU on one of those properties needs to respect massing, roofline, and materials, the city will push back on something that reads as an addition dropped from a different era. In the Coronado Cays, where the housing stock skews newer and lots are often larger with waterway access, the constraints shift more toward setbacks and HOA rules than historic review. Coronado Shores condos are a different animal altogether and rarely support ADUs. For most Village and Cays single-family homeowners, a detached backyard unit or a thoughtfully designed garage conversion is where the conversation starts. Demand near Orange Avenue and the NAS North Island perimeter stays high year-round, so the rental case here is unusually strong.
