A rare four-bedroom footprint in the El Sobrante highlands... Four bedrooms in just over a thousand square feet is an unusual find at this price point in the East Bay. The layout works hard — room for a growing household, a dedicated home office, or space that adapts as your needs change. One full bath serves the home... and a lot with real room. At 7,500 square feet, the parcel offers far more outdoor space than the home’s footprint suggests. Room for gardens, play space, outdoor dining, or future expansion — with mature surroundings typical of the El Sobrante hills. Groundwork already in place... A separate structure sits in the rear yard: approximately 125 square feet on a finished slab, with electrical already installed. Whether you envision a studio, workshop, home office, or something more ambitious, a meaningful piece of the work is done. Buyer to verify permit status and any accessory dwelling unit potential with Contra Costa County. The El Sobrante Valley setting... Quiet, established, and closer to everything than you’d expect. San Pablo Dam Road handles daily shopping and errands minutes away. Kennedy Grove Regional Recreation Area and San Pablo Reservoir put hiking, picnicking, and open space at your doorstep. I-80 and Highway 24 make Berkeley, Richmond, and points beyond a straightforward commute. Served by West Contra Costa Unified School District.
