6401 Tassajara presents a rare opportunity to acquire approximately 1,432 acres of agricultural land in the eastern Contra Costa County foothills, immediately adjacent to the San Ramon and Dublin city boundaries. Comprised of three parcels and zoned A-80 (Exclusive Agricultural District), the property offers a unique combination of large-scale land ownership, established ranch infrastructure, and proximity to some of the Bay Area’s most affluent residential communities. The ranch includes rolling terrain, open grazing land, natural water sources, and elevated areas with expansive valley views. Existing improvements include fencing, corrals, water storage facilities, watering troughs, wells, and access to electricity, supporting ongoing agricultural operations. The northern portion of the property encompasses approximately 837 acres of rangeland currently utilized for livestock grazing, while the southern acreage includes an existing homesite and an additional development area suitable for agricultural-related uses, subject to applicable regulations and approvals. Located just minutes from San Ramon, Dublin, major retail centers, and the Dublin/Pleasanton BART Station, the property benefits from convenient access to regional transportation and urban amenities while maintaining the privacy and character of a working ranch. The surrounding area is anchored by major employers, established residential neighborhoods, and continued economic activity throughout the Tri-Valley region. The property is enrolled in the Williamson Act and features a combination of conservation-protected acreage and productive agricultural land, creating an opportunity for ownership of a significant landholding within one of Northern California’s most supply-constrained regions. With its scale, location, existing infrastructure, and long-term agricultural utility, 6401 Tassajara offers buyers the chance to secure a substantial foothill ranch asset in close proximity to the Bay Area’s major population and employment centers.
