Rancho Santa Margarita Custom Home Construction
A single cohesive master-planned community (a 5,000-acre plan begun in 1984, incorporated 1996 as a self-contained urban village); Dove Canyon is the premier tier — 24-hour guard-gated, roughly 1,200 homes around a private Jack Nicklaus golf course — with Rancho Cielo a smaller gated enclave and the balance large-lot family tracts under SAMLARC master-association governance. Avorino builds throughout Dove Canyon, Rancho Cielo, Melinda Heights, Robinson Ranch, and Trabuco Highlands. Avorino runs hillside custom homes end-to-end. Soils + geotechnical engineering and retaining-wall design land in the package before drawings finalize, so foundation specs are sized against the actual soils report — not the flat-lot template.7+ years of Orange County experience · 150+ completed projects · 4.8 Yelp average across 35+ reviews.

Custom and high-end remodel work concentrates in guard-gated Dove Canyon and Rancho Cielo, where sub-association architectural committees impose stricter window, paint, and finish rules than the rest of RSM on top of SAMLARC master-association review (twice monthly); foothill lots require slope and grading consideration. Avorino operates in Orange County under General-B License #1107538, with 7+ years of OC experience and a 4.8-star Yelp average across 35+ reviews. Architecture, structural engineering, permitting, construction, and the tiered warranty all sit under one roof — one accountable builder from first conversation through final handover.
Avorino's design-build model means architecture, structural engineering, Title 24 calculations, and soils (where Rancho Santa Margarita lots require it) all sit under one roof. You sign once at the start; the coordination across disciplines runs through one office.
Submittal, plan-check comments, resubmittal, and final inspection all run through one office. Avorino builds drawings against how Rancho Santa Margarita handles slope engineering, retaining wall design, and drainage built into the foundation phase, not bolted on after, so the set walks in ready for what the city checks.
Cabinetry, stone, tile, paint, fixtures, appliances — every line item picked against a written allowance log so the bid doesn't drift during construction. Rancho Santa Margarita clients see the finish board before demolition starts.
Every Avorino build ships with a tiered construction warranty: 1-year fit & finish (paint, trim, mirrors, flooring, cabinets, countertops), 4-year systems (plumbing, electrical, HVAC), 10-year structural. Same Avorino team you started with takes the warranty call.

“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 we build in Rancho Santa Margarita (4)
Soils + geotechnical engineering, retaining design, view-line preservation — landed up-front.
Cantilevered volumes, hillside structural engineering carried in-house.
Classical proportions with restrained ornament. Finish carpentry the contemporary palette can't match.
Whole-house gut renovations that read as new construction when tear-down is impractical.

Rancho Santa Margarita permit reality
Avorino drafts the drawings for single-family custom builds against Rancho Santa Margarita'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 city allows.
Rancho Santa Margarita lot profile
At the base of Saddleback Mountain against the Cleveland National Forest — foothill terrain throughout, with Robinson Ranch set directly into the Santa Ana Mountain foothills.
