Property Description
A rare investment opportunity or the perfect owner-occupant property in the heart of SoMa. Live in one unit and collect rental income from the other while enjoying the character and charm of a bygone San Francisco era. Built during SoMa's Edwardian period, long before much of the surrounding neighborhood took shape, this well-maintained two-unit building sits on an exceptionally quiet side street while remaining close to everything the city has to offer. Rich with original character and period details, the property seamlessly blends historic charm with modern upgrades. The lower unit features a beautifully remodeled two-bedroom, two-bath floor plan, along with a large bonus room that could easily serve as a third bedroom, home office, or guest space. The spacious chef's kitchen is equipped with stainless steel appliances, abundant cabinetry, stone countertops, and a classic subway tile backsplash. Sunlight pours into the front living room and front bedroom during the morning hours, while the rear bedrooms enjoy warm afternoon light. Start your day with coffee on the private rear deck overlooking the yard. And yes, there is ACTUALLY a backyard in SoMa. The expansive outdoor space offers a rare urban retreat with endless possibilities for gardening, entertaining, or simply relaxing outdoors. The upper unit is a spacious two-bedroom apartment that is currently tenant occupied, providing immediate rental income. Both units feature in-unit laundry, and the property includes a massive basement storage area. Commuters will appreciate the property's unbeatable location, with convenient access to 101 and 80 freeways, multiple Muni lines, and Civic Center BART. Daily errands are a breeze with Costco, Trader Joe's, Victoria Manalo Draves Park, restaurants, cafes, and neighborhood amenities all within walking distance. Experience the perfect blend of historic San Francisco character, income potential, outdoor space, and urban convenience. This is SoMa living at its finest.
