Property Description
Reimagined for modern living with a 4 bedroom, 3 bath main home and 1 bedroom permitted ADU! 18977 Patton has been expanded on, and brought to its exceptional full potential over the last 7 years by the owner for the owner. You know what that means - thoughtfully designed curated finishes meant for the enjoyment of those whom have owned it, not just for resale. Inside, bright open living spaces connect easily to the outdoors, with a large living room that has french doors that open into the fenced in front play yard. A large dining room beyond that also opens up to the back yard, while the kitchen anchors the space and stands out with stainless steel appliances, a gas range with pot filler and custom hood, and a farmhouse-style stainless steel sink. Warm wood tones, modern fixtures, and playful tile choices give the home a polished but inviting feel. The first-floor primary suite has a boutique hotel-esque feel and features a walk-in closet with hidden stairs leading to a bonus lower-level flex space, plus a spa-inspired bath with concrete collective terrazzo tile, brass finishes, stand alone soaking tub, oversized glass shower, and dual vessel sinks. A second bedroom and full spa-like tranquil bath are also on the main level, along with a dedicated laundry room with washer/dryer hookups. Upstairs are two additional bedrooms with high ceilings, large closets and a third full shower over tub bathroom. Outside, contemporary modern siding siding, dark-framed windows and trim, a pavers courtyard, privacy fencing, mature trees, and decomposed granite create a clean, low-maintenance setting with multiple areas to relax or entertain. The detached 1-bedroom ADU includes its own full kitchen with stainless steel refrigerator, microwave, electric oven, and dishwasher, plus a full bath and in-unit washer/dryer, heat and AC, and separate PGE meter —ideal for extended family, guests, office use, rental opportunity, or flexible independent living. Dont miss the side yard with additional storage shed, a dog washing station and veggie beds! Castro Valley is known for its strong community feel, well-regarded schools, and easy access to outdoor recreation, Lake Chabot Regional Park, and nearby open space. Shops, restaurants, BART, and commuter routes are all within convenient reach, offering a great balance of neighborhood comfort and East Bay connectivity.
