Property Description

This bright and contemporary Richmond District duplex presents a rare opportunity just steps from Golden Gate Park. Newly built in 1994, both units offer three bedrooms, two full bathrooms, a sun‑filled living room, a formal dining room, a spacious kitchen. Additional in‑unit laundry in the top floor, modern comforts seldom found in the neighborhood's older housing stock. Thoughtfully designed floor plans, abundant natural light, and strong rental potential make this property an excellent choice for both owner‑occupants and investors. The street‑level bonus space adds even more versatility, offering a flexible room with an adjoining playroom and a full bathroom perfect for guests, extended family, or creative use. Additional highlights include a large garage with extensive storage and potential expansion opportunities (buyers to verify with the City), along with a charming, low‑maintenance backyard ideal for relaxation or outdoor entertaining. With its unbeatable location and versatile layout, this is a rare chance to own a contemporary multi‑unit home in one of San Francisco's most desirable communities.
