The details matter.

Our headquarters is at 243 Prospect Street in La Jolla, California. We serve all of San Diego County, including La Jolla, Del Mar, Encinitas, Carlsbad, Oceanside, and Chula Vista, and continue north through Orange County.

Yes. Troia Construction holds California Contractors State License Board (CSLB) license #1151054. We are a fully licensed General B contractor qualified to perform residential and commercial construction across California.

Most jurisdictions now target 60-day reviews, but coastal overlays or design review boards can extend timelines. We shepherd submittals, respond to plan check comments, and keep you informed of every milestone.

We coordinate electrical load calculations, gas sizing, sewer tie-ins, and water pressure requirements. Our field teams execute trenching, conduit runs, and service upgrades so your ADU integrates cleanly with the primary residence.

State law has relaxed parking mandates when your property is within a half-mile of public transit or includes a garage conversion. We verify local ordinances and, when required, plan compliant on-site spaces without compromising design.

Detached ADUs typically require four-foot side and rear setbacks, while attached units follow primary-structure standards. We confirm zoning overlays early so your design maximizes the allowable building envelope.

Projects inside the California Coastal Zone can trigger extra reviews. We collaborate with planners, prepare supplemental coastal documentation, and manage hearings to keep your permit on track.

Construction durations range from four to seven months depending on scope and site access. We build detailed schedules, maintain owner-level oversight, and communicate weekly progress updates.

We guide clients through lender conversations, highlight construction-to-permanent loans, and share best practices for leveraging home equity while keeping carrying costs predictable.

No. As a licensed General B contractor, ADUs are a core specialty, but we also deliver custom homes, major remodels, and additions. The one trade we self-perform and offer as a standalone scope is structural framing. Every other trade is coordinated and managed under our general contract rather than sold individually.

The owner attends weekly site walks, leads subcontractor coordination, and handles key client updates personally. Direct involvement from preconstruction through turnover is how we maintain accountability on every project.

Absolutely. We collaborate with architects, interior designers, and engineers throughout California and can recommend partners suited to your project’s scope and aesthetic.
