Frequently asked questions

The details matter. Here's how Troia Construction navigates permitting, project delivery, and client communication across San Diego County.

Where do you work?

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

How long do ADU permits take in San Diego County?

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.

How are ADU utilities and tie-ins handled?

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.

Do ADUs require additional parking?

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.

What setbacks should I expect for an ADU?

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 allowable building envelope.

How do coastal overlays impact ADU approvals?

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.

How long does an ADU build usually take?

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

Can you help me understand ADU financing options?

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

Do you only build ADUs?

ADUs are a core specialty, but we also deliver custom residences, multifamily improvements, and boutique commercial builds. We frequently partner with clients on targeted trade scopes such as framing, foundations, roofing, and siding.

How hands-on are the founders?

Robert and Angelos attend weekly site walks, lead subcontractor coordination, and handle key client updates personally. They remain involved from preconstruction through turnover.

What is your founders’ pledge?

Founder accountability, weekly status updates with photos, transparent budget tracking, and rapid decisions on site. If you call, a founder answers.

Do you work with outside design teams?

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