Elegant Nob Hill Triplex with Renovated Flats, Parking & Bonus Studio! Perched atop iconic Nob Hill just one block from the Fairmont and across from the Cable Car Museum this elegant 1912 building offers timeless charm with updated interiors and incredible flexibility. The property features three spacious flats totaling approx. 4,500 sq ft, plus garage parking for 3 small cars and a bonus studio with full bath. The top two flats are vacant and recently renovated with updated kitchens, stainless appliances, engineered hardwood floors, in-unit laundry hookups, and two bedrooms plus a fainting room (ideal for guest space or office). Formal living and dining rooms, fresh paint, and split baths complete each home. The lower flat is tenant-occupied with stable, long-term rental income. The garage level was expanded with permits in 2005. All units have updated electrical and no knob-and-tube. With expansion potential and a premier location surrounded by cafs, landmarks, and transit, this is a rare opportunity for investors or owner-users alike. Come early!
