Overview

Fully Vacant. Two Units. Endless Possibilities. Rare opportunity to own a fully vacant 2-unit building in coveted Noe Valley, perfectly situated where Bernal Heights and the Mission meet. Each 2-story unit offers 3 bedrooms and 2.5 baths, expansive living/dining rooms, and open kitchens designed for gathering. Large picture windows and skylights fill the homes with natural light that reflects off hardwood floors. Main levels include powder rooms and in-unit laundry, while upstairs bedrooms share updated baths. The back unit features a serene bedroom with a private deck. A coveted 2-car garage provides rare convenience, and the lifestyle outside your door is just as appealing. Enjoy the best of Noe Valley, with boutique shopping, cozy cafs, acclaimed restaurants, and the year-round Saturday Farmers' Market. Explore Bernal Heights Park for sweeping views, savor Mitchell's Ice Cream next door, or dive into the Mission's buzzing dining and nightlife. Whole Foods, BART, tech shuttles, and quick access to 101/280 make city living seamless. Two vacant homes, one unbeatable location -- and a rare opportunity to fast-track condo conversion and unlock long-term equity potential in one of San Francisco's most desirable neighborhoods.
