Overview

1231-1233 4th Avenue is a well-maintained, two-unit building located in the heart of San Francisco's sought-after Inner Sunset neighborhood. Both units are delivered vacant. The property has benefited from recent improvements, including fresh interior and exterior paint along with kitchen and bathroom updates, offering a move-in-ready opportunity with long-term flexibility. Both units feature hardwood floors, formal living and dining rooms, excellent natural light, and in-unit laundry. The lower unit is configured as a spacious two-bedroom with the flexibility to function as a three-bedroom. The upper unit offers three bedrooms with formal living and dining rooms or can be utilized as a four-bedroom residence, and includes new stainless steel kitchen appliances. A lush private yard provides a peaceful outdoor retreat, while the two-car garage includes additional bonus space at the rear, offering potential for expansion, home office, gym, or future ADU considerations (buyer to verify). With both units delivered vacant, this property presents an exceptional opportunity for an owner-occupant to occupy the entire building or create a flexible multi-generational living setup. Ideally situated near Golden Gate Park, Irving Street's dining and shopping corridor, UCSF, and major transit lines, this Inner Sunset property combines location, condition, and versatility in one compelling offering.
