San Francisco
San Francisco presents some of Northern California's most demanding surveying conditions: steep hillside lots, tightly packed row houses, and a property record system shaped by the 1906 earthquake and fire. We bring deep local knowledge to every SF project, from Pacific Heights to the Bayview.
Explore RegionEast Bay
The East Bay spans two counties and an extraordinary range of terrain — from bay-front flatlands to the rugged East Bay Hills, across the Hayward Fault and into the suburban valleys of Contra Costa County. We survey properties throughout Oakland, Berkeley, Walnut Creek, Fremont, and dozens of communities in between.
Explore RegionNorth Bay
The North Bay encompasses Marin's coastal hills, Sonoma's wine country, and Napa's legendary vineyards — a landscape defined by rolling terrain, agricultural heritage, and strong land conservation policies. Our surveys serve vintners, ranchers, homeowners, and developers across three counties with distinct regulatory environments.
Explore RegionSacramento
The Sacramento region sits at the confluence of the American and Sacramento Rivers, where California's agricultural heartland meets the Sierra Nevada foothills. From downtown Sacramento's historic grid to new master-planned communities in Elk Grove, Folsom, and Roseville, we provide precise surveying services adapted to the Capital Region's unique conditions.
Explore RegionSouth Lake Tahoe
Surveying at Lake Tahoe combines alpine terrain, heavy regulatory oversight from the Tahoe Regional Planning Agency (TRPA), and a limited seasonal work window. At 6,225 feet elevation, the Tahoe Basin demands a surveyor who understands mountain conditions, TRPA coverage requirements, and the unique challenges of working in one of America's most protected landscapes.
