What does a custom home actually cost 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.

Can you work with my architect?

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.

How are change orders handled?

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.

What happens after we move in?

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.

How much does a custom home cost in Orange County, and how long does it take?

Orange County custom homes typically run $450–$900+ per finished square foot, with most projects landing between $900K and $5M+ all-in.

The six phases of an Avorino custom home build in Orange County
Phase	What happens
Discovery + program	We meet at the site or at your kitchen table. Goals, constraints, the version of the house you actually want to live in — captured in writing before drawings start.
Design coordination	We work directly with your architect (or one we introduce). Drawings, structural, mechanical, finishes — coordinated so trades don't fight each other in the field.
Pre-construction	Engineering, surveying, geotechnical, soils. Permits submitted, comments resolved. Constructability flagged in writing before a single trade arrives.
Vertical construction	Foundation, framing, mechanical, electrical, and plumbing, envelope. Weekly progress reports, one builder on point through every trade.
Finish work	Cabinetry, stone, tile, paint, finish carpentry. The trade where rushed jobs reveal themselves; ours reads as careful.
Walk + warranty	Punch close, final inspection, owner walk-through, then the tiered warranty (1-year fit & finish, 4-year systems, 10-year structural). The same Avorino team on the phone after move-in as before it.
