Upgraded Mission Dolores Mixed-Use Property

3901 18th Street presents an exceptional opportunity to own a well-maintained corner retail property in the heart of San Francisco's Mission Dolores neighborhood. The building features two ground-floor retail units, both secured with brand-new long-term leases beginning September 1, 2025. Tenancy includes a long-standing massage business and a highly regarded salon opening soon in the prominent corner space, ensuring stability and visibility. A versatile upstairs unit, complete with a full bathroom, offers flexibility for office use, a small art studio, or storage. The property has been thoughtfully upgraded with ADA-compliant entry and restrooms, recently replaced electrical systems, high ceilings, abundant natural light, and open floor plans. Significant capital improvements include a steel seismic retrofit and a new concrete perimeter foundation, providing long-term structural security. Surrounded by neighborhood amenities and well-served by public transportation, this property combines strong tenancy, prime location, and turnkey condition, making it a rare investment opportunity in one of San Francisco's most desirable districts.
