General contractor work in Rancho Santa Margarita, CA by Ulloa Construction

CSLB Lic. #1144906 — Serving Orange County

General Contractor in
Rancho Santa Margarita, CA

Serving Rancho Santa Margarita and all surrounding South Orange County communities.

Rancho Santa Margarita is one of South Orange County's newest incorporated cities — a master-planned community built largely in the 1980s and 1990s around the man-made Rancho Santa Margarita Lake, featuring a network of planned neighborhoods, excellent schools, and a strong HOA-governed community identity. Ulloa Construction serves Rancho Santa Margarita (zip code 92688) with kitchen remodels, bathroom renovations, flooring installations, interior updates, and room additions. We work throughout RSM's neighborhoods including Tesoro, Melinda Heights, Dove Canyon, and the areas surrounding the town center.

Rancho Santa Margarita homes built in the late 1980s and early 1990s are entering their prime renovation window — kitchens and baths that are functionally sound but aesthetically dated, and interiors that benefit from updated flooring, lighting, and modern finishes. Our team holds CSLB License #1144906 and is experienced coordinating with Rancho Santa Margarita's HOA design review process. We serve RSM alongside neighboring Mission Viejo, Coto de Caza, Laguna Hills, and Aliso Viejo.
