Tucked at the end of a quiet court in North Napa's Bel Air neighborhood, this rare property offers two fully detached homes on one lot, each with its own driveway and private yard. Ideal for multi-gen living, rental income, or flexible use. The main home is single level and features 4 beds, 2 baths, a renovated kitchen open to the living room, a separate family room with wood-burning fireplace and yard access, newer roof, fresh paint, and updated lighting. Two bedrooms open to the yard, plus a finished shed offers space for an office, studio or extra storage. Privately set at the rear, the newly built ADU has never been lived in and lives like a modern retreat, with 1 bedroom and 1 bathroom on the main level, and 2 ensuite bedrooms upstairs with hill views and skylights. A large slider in the ADU's living room opens to the private yard, enhancing indoor-outdoor flow. Light-filled, functional layout with quality finishes. Close to schools, parks, shopping, The Vine Trail, and easy Hwy 29 access, this is one of Napa's best values. Live in one, rent the other, or share both!
