6727 Sunnyslope Ave, Castro Valley, CA 94552
Tucked away in the Castro Valley hills on a sprawling 0.89-acre lot comprised of two separate adjacent parcels, this unique property offers the perfect blend of privacy, space, and natural beauty. Surrounded by abundant wildlife and serene hillside views, the setting feels like your own private retreat—yet remains conveniently close to town. The home features two spacious primary suites, ideal for multi-generational living or hosting guests in comfort. Inside, you’ll find soaring vaulted open-beam ceilings that create an airy, inviting atmosphere, along with central air conditioning for year-round comfort. The heating has two zones and the kitchen has been pre-plumbed with propane if a gas cooktop is preferred. Step outside to enjoy three recently rebuilt decks (one has already been pre-plumbed with propane for your BBQ), providing multiple spaces to relax, entertain, and take in the peaceful surroundings. The home has an attached 2-car garage and it also has a separate driveway leading an attached workshop (approx 9' 8" x 22' 8") and a RV/Boat garage (approx. 11'8" x 22' 8") that are perfect for hobbies, projects, or additional storage. The property is accessed via a private drive with only a handful of neighboring homes, this is a rare opportunity to own a tranquil hillside escape with room to breathe, explore, and truly unwind. The downstairs area has a large office, family room and a full bathroom with a separate entrance and a spiral staircase that connects it to the upstairs living area. There are plenty of separate areas in this home allowing its owner to configure customized usage to meet their specific needs. All section 1 work from the East Valley Termite report dated 9/11/25 has been completed.
