Set on a private, sunny street-to-street lot in Mill Valley, 12 Alturas Way blends classic charm with effortless indoor-outdoor living. Terraced gardens and a generous sun deck create the kind of setting that feels both welcoming and secluded. Inside, an enclosed porch leads to a bright living room with hardwood floors and open-beam ceilings, flowing into a remodeled kitchen and comfortable open floor plan. A large bay window frames wide Tam Valley views. Two bedrooms and a full bath complete the main level. Downstairs, the spacious primary suite offers a large walk-in closet, a private bath, and sliding glass doors that open directly to an expansive deck. The home is approximately 1,380 square feet plus storage, a laundry room, and ample parking. The 4,800-square-foot lot includes a second entrance at 909 West California Street, adding flexibility, privacy, and future potential. Minutes to Tam Junction with easy access to 101, 15 minutes to the beach, and a quick hop to Miller Avenue and downtown Mill Valley. A home you won't want to miss.
