Coronado ADUs, built by the owner.
On Coronado, where lots are tight and standards are exacting, Troia builds discreet, high-quality ADUs and guest quarters, with the owner personally leading every job.
Why build an ADU in Coronado?
Coronado is a small, historic island community where character and detailing matter enormously. ADUs here have to be quiet additions that fit the streetscape. We approach them with the craftsmanship and restraint the island expects.
Space is at a premium, so Coronado ADUs are often refined guest quarters, studios, or above-garage units rather than sprawling builds. We make every square foot work and keep the construction footprint considerate of close neighbors.

Approvals in Coronado.
Coronado is its own city with its own review standards, and the island lies within the Coastal Zone. ADU projects here typically involve both city review and coastal considerations. We prepare for Coronado’s specific expectations and manage the process end to end.
We handle drawings, submittal, plan-check responses, and inspections, so you get a finished ADU instead of a paperwork project.
