Income-producing opportunity in Napa's coveted Alphabet Streets, just steps from Downtown. 1620 Spencer Street offers two fully separate residences on one parcel: a 2-bed, 1-bath main house and a newly built, never-occupied detached 1-bed, 1-bath ADU. Lease both for dual rental income, or live in one and let the other help pay the mortgage. The ADU sits privately at the rear of the property with its own entrance and private courtyard, plus an in-unit washer/dryer and split-system heating and cooling. It is a truly independent, rent-ready unit awaiting its first tenant, and it is also well suited to multigenerational living, guests, or a home office. The main house blends character with thoughtful updates. Original hardwood floors run through the living room and both bedrooms. The updated kitchen features a farmhouse white ceramic sink, stone tile flooring, a subway tile backsplash, and charming light fixtures, with a dedicated laundry area nearby. The refreshed bath offers tile floors, lime-washed walls, and modern fixtures. Major systems are done, including HVAC, an updated electrical panel, and owned solar, which keeps operating costs and near-term capital expenses low. Outside, the backyard offers entertaining space, a hobby vineyard, and room for alfresco dining. Heritage tree-lined streets and close proximity to Downtown Napa's acclaimed restaurants, tasting rooms, boutique shopping, live entertainment, and year-round events drive strong tenant demand. Two units, updated systems, owned solar, and a prime near-Downtown location, all in one purchase.
