Oceanside ADUs, built by the owner.
Oceanside pairs coastal access with some of North County’s best ADU value. Troia builds detached ADUs, garage conversions, and rental units across the city, owner-led throughout.
Why build an ADU in Oceanside?
Oceanside has grown into one of the smartest places in the county to build an ADU. Land still pencils, rental demand is strong with the beach and Camp Pendleton nearby, and the city has been actively encouraging more housing.
We build Oceanside ADUs as serious investments: separate metering where it makes sense, durable exteriors for the coastal climate, and layouts that rent well year-round. Owner-led means your budget and schedule stay tight.

Approvals in Oceanside.
Oceanside is its own city and processes ADUs through its Development Services, with shoreline areas in the Coastal Zone. We prepare the submittal to Oceanside standards and manage any coastal review for your parcel.
We handle drawings, submittal, plan-check responses, and inspections, so you get a finished ADU instead of a paperwork project.
