San Diego ADUs, built by the owner.
From North Park to Point Loma, Troia builds detached ADUs, garage conversions, and junior ADUs across the City of San Diego, with the owner on site from permit to keys.
Why build an ADU in San Diego?
San Diego has some of the most ADU-friendly rules in California. The City’s ADU Bonus Program lets qualifying lots in transit priority areas build more than one ADU, turning a single backyard into real rental income or multigenerational space.
We handle the parts that trip people up: load calculations, sewer tie-ins, and Development Services plan check. Because we self-perform the framing, your structure goes up square and on schedule instead of waiting on a rotating cast of subs.

Approvals in San Diego.
Permits run through the City of San Diego Development Services Department. Most ADUs are reviewed ministerially on a 60-day clock, and the City’s Bonus ADU Program can unlock additional units on transit-served lots. We prepare the submittal, carry it through plan check, and keep you posted at every milestone.
We handle drawings, submittal, plan-check responses, and inspections, so you get a finished ADU instead of a paperwork project.
