Your Orange County general contractor.

A general contractor is responsible for the whole build: scheduling and managing every trade, pulling permits, coordinating inspections, controlling the budget, and delivering the finished result. Avorino also carries the design and engineering in-house, so there is one contract and one point of accountability instead of four.

Yes. Avorino holds California State License Board General-B License #1107538 and is bonded and insured. Every project is contracted and built by Avorino, not brokered out to a rotating set of subs.

Splitting it means you own the coordination and the gaps: the architect's drawing meets the builder's price only after you have paid for both, and change orders live in the seam. Design-build puts design, engineering, and construction on one contract, the price is set before you break ground, and the company that drew it is the company that builds it.

It depends entirely on scope. As reference: ADUs typically run $85K–$440K+, additions and renovations vary widely by size and finish, and ground-up custom homes start in the high six figures. Avorino quotes a fixed-price design-build contract after a scope review, so the number you sign is the number at the warranty handover.

Avorino works across 37 Orange County cities and communities: from the coast (Newport Beach, Laguna, Dana Point) through central OC (Irvine, Tustin, Costa Mesa, Santa Ana) to north county (Anaheim, Fullerton, Yorba Linda) and the south master-plans (Mission Viejo, Ladera Ranch, Rancho Santa Margarita).

Yes. Avorino runs every submittal, plan-check correction, and inspection through one office across all 37 OC cities. You sign once at the start; permitting and inspections run through us from there.
