Carlsbad ADUs, built by the owner.
Carlsbad’s larger lots and family neighborhoods are ideal for detached ADUs. Troia builds them across La Costa, Aviara, and Olde Carlsbad, owner-led from foundation to finish.
Why build an ADU in Carlsbad?
Carlsbad tends to have more room to work with than the dense coastal villages to the south, which opens up genuinely spacious detached ADUs, home offices, and multigenerational suites. We use that space to build units that feel like real homes, not add-ons.
With strong schools and a steady rental market, Carlsbad ADUs serve double duty as flexible family space now and an income-producing asset later. We build to a standard that supports both.

Approvals in Carlsbad.
Carlsbad is its own city and reviews ADUs through its Community Development department, with western Carlsbad partly in the Coastal Zone. We tailor the submittal to Carlsbad’s requirements and handle coastal review where it applies.
We handle drawings, submittal, plan-check responses, and inspections, so you get a finished ADU instead of a paperwork project.
