Custom home builder in Orange County.

Coastal Orange County builds typically run $450 – $900+ per finished square foot depending on lot complexity, finishes, and structural ambition. We tell you on day one which range your project will land in — and what specifically would push it to the next range.

Plan on eighteen-to-twenty-four+ months from final design to certificate of occupancy on a typical OC custom; complex hillside or estate-scale work runs longer. We map your project against that range during the first call so you can sequence other commitments around it.

Yes. Most of our custom homes start with the client's architect already engaged. We coordinate, we don't compete; design fees stay between you and the design firm.

Written, priced, signed before work starts. The single biggest source of custom-home regret is verbal field changes that get billed three months later — we make that physically impossible by routing every change through paper.

Final walkthrough plus the tiered warranty — 1-year fit & finish, 4-year systems, 10-year structural — and a warranty binder. Same Avorino team on the phone for warranty work, no 1-800 routing, no runaround. Most of our clients call us back for a second project — that's the relationship we underwrite.
