Areas We Serve in the East Bay and Bay Area, California
Taragano Design and Build is a licensed design-build contractor, CSLB #1143420, based in Concord, California. From here, we build across the East Bay and the greater Bay Area. We serve four counties: Contra Costa, Alameda, Marin, and San Francisco. Wherever you are, one team handles your design, permits, and construction.
We do every kind of residential work. But we are known best for three: home additions, whole-house remodels, and ADUs. Those are the projects that change how a family lives, and the ones we are proudest to build.
Where We Focus: Danville, Lafayette, Orinda, San Ramon & Walnut Creek
Five cities are the heart of our work. In each one, we have built real projects and know the local rules by heart. If you live here, you are in the best possible hands.
Danville
Home additions, whole-house remodels, and ADUs across Danville and the San Ramon Valley. We know the Town’s Permit Center and the Garden Cottage ADU program. See our Danville page.
Lafayette
Lafayette lots are large and often sloped, which is where we shine. Additions, full remodels, and ADUs up to 1,200 square feet. See our Lafayette page.
Orinda
Orinda means hillside sites and wildfire zones. We handle the geotechnical work most builders avoid. Additions, whole-house remodels, and ADUs. See our Orinda page.
San Ramon
From Windemere to Gale Ranch, we build additions, remodels, and ADUs across San Ramon, including HOA neighborhoods. We manage HOA approvals for you. See our San Ramon page.
Walnut Creek
One of our busiest markets. Additions, whole-house remodels, and ADUs from Northgate to Saranap, and garage conversions are a local specialty. See our Walnut Creek page.
More East Bay Cities We Serve
We also build throughout the East Bay. That includes Concord, our home base, plus Alamo, Moraga, Pleasant Hill, and the Blackhawk community. We build additions, remodels, ADUs, kitchens, and baths across all of them.
Beyond the East Bay
Our work reaches past Contra Costa County. We build in Berkeley and Oakland, where we have completed major additions and full remodels. We also serve San Francisco and Marin County, including Sausalito, Tiburon, and Mill Valley.
The Counties We Cover
We are licensed to build across four Bay Area counties. In Contra Costa County, we cover the whole I-680 corridor and the Lamorinda area. In Alameda County, we serve Berkeley, Oakland, and nearby cities. We also work in Marin County and the City and County of San Francisco.
