Coto de Caza New Construction Contractor
A guard-gated, roughly 5,000-acre master-planned community (opened 1986) in unincorporated Orange County — no city hall, county-governed — and one of OC's oldest and most expensive gated communities, with a strong equestrian identity and premium lot values. Avorino builds throughout The Village, Los Ranchos Estates, Hillsboro, Atherton, and Weatherly. Avorino's hillside ground-up builds carry the geotech work, retaining design, drainage plan, and hillside-grading sign-off up-front. Foundation engineered against the soils report — no surprise underpinning during framing.7+ years of Orange County experience · 150+ completed projects · 4.8 Yelp average across 35+ reviews.

Governance runs three layers deep — the Coto de Caza Master Association, a neighborhood sub-association, and an Architectural Review Board that must approve virtually any exterior change (paint, landscaping, hardscape, pools). Because it's unincorporated there is no city planning department, so OC County handles permitting while the homeowners association and ARB function as the de facto local design authority; several tracts sit on large equestrian-zoned lots. Avorino has 7+ years of OC ground-up experience under General-B License #1107538 — single-family residences, multi-unit residential, small-format commercial, and ADU pairings on existing lots. Architecture, structural engineering, surveying, soils, permitting, construction, and the tiered warranty under one roof.
Geotechnical soils report, retaining-wall engineering, drainage plan, and hillside-management compliance landed up-front. Foundation engineered against the soils report — no surprise underpinning during framing.
Architecture, structural engineer of record, soils + geotechnical engineer, surveyor, and Title-24 energy coordinated before drawings finalize. Drawings get to plan check the first time — not the third.
OC Development Services submittals, comment rounds, resubmittals, fees, and inspection scheduling — run through one office as a single coordinated track, comments resolved in writing.
Fixed-price design-build contract with line-item costs + written allowances. Real-time cost visibility during design phase; selection sign-off before construction; weekly progress reports through Certificate of Occupancy.

“These are the best people in the business. I used Avorino to build my own ADU. They beat every single price I got and on top of that did an excellent job finishing it in no time. Truly the best of the best — highly recommended.”

What ground-up actually takes in Coto de Caza.
Coto de Caza permit reality
Avorino drafts the drawings for ground-up residential and small commercial against Coto de Caza's published code. The variable is which plan checker draws your set and what they flag — the set is built for that, so comments resolve in one round where the county allows.
Coto de Caza lot profile
Rolling hills and canyons in the Santa Ana Mountain foothills — oak groves, two major ridgelines, and elevations of roughly 700-900 ft.

Yes. Avorino carries California General-B License #1107538 and delivers ground-up new construction in Coto de Caza end-to-end: design, structural engineering, permits, and construction under one roof. As the Coto de Caza new construction contractor and general contractor on your project, Avorino owns the schedule and the outcome, rather than coordinating a chain of subcontractors you'd manage yourself.
Coto de Caza ground-up typically lands at $425 – $700 / sqft+ depending on lot complexity, finish level, and structural ambition. Avorino quotes a fixed-price design-build contract, the bid you sign is the bid you sign.
Plan on 14 – 22+ months from initial design through certificate of occupancy. The variance is permitting + soils, not vertical construction. We tell you on day one which side of that range your project lands on, and what would push it up.
Yes. Avorino coordinates the architect of record, structural engineer, soils + geotechnical engineer, and surveyor. You see one project schedule and one point of accountability; the consultants invoice Avorino directly. Hillside-management compliance and retaining engineering are part of the same package.
A tiered warranty — 1-year fit & finish, 4-year systems, 10-year structural — handled by us. The same Avorino on the phone after Certificate of Occupancy as before it.
Neither the way people assume. Coto is on sanitary sewer run by Santa Margarita Water District (treated at its Chiquita plant), not septic and not OC San, so the OC San capacity charge doesn't apply. What does drive cost is the Very High Fire Hazard Zone (WUI construction, OCFA review) and hillside grading on estate lots. Avorino carries the fire and grading work.
