Welcome to 439-441 Detroit St., a rare multi-residential property with two VACANT single-family homes, connected by a party wall and situated on two separate lots at the end of a cul-de-sac. Tastefully remodeled with hardwood floors, high ceilings, skylights, updated bathrooms and smart home features (EV charger, smart locks, security cameras), and more. These "Twin Homes" offer great flexibility for owners, investors, developers or multi-generational families. The bonus mezzanine space, currently a gym, laundry room and recreation room, could be expanded or converted into an ADU with a separate entrance. The expansive 3-car garage has almost 18-foot ceilings & multiple windows, offering development potential. Lush landscaped yards with terraces and a large brick patio provide perfect entertainment space. The main entrance to this property is located in front of the Detroit Steps Mini Park, providing a very quiet, picturesque walkway to the Detroit Steps. Located in the Sunnyside neighborhood, close to Glen Park Village, BART, Muni, Parks, freeway access and excellent schools, this property is an ideal blend of convenience and tranquility. A MUST SEE!
