2977-2979 21st Street, San Francisco, CA 94110

Property Description

Notably the building where OpenAI first took shape, 2977-2979 21st Street is a rare 1885 Victorian mixed-use property in a prime Inner Mission location, offering a compelling blend of character, income, and owner-user potential. Situated near Treat and 21st, the building includes a stunning, fully remodeled two-level owner's unit delivered vacant, a tenant-occupied garden flat ready for future vision, and a leased commercial storefront with vintage curb appeal. Unit 1 (2977A) is a modern two-level penthouse spanning approximately 1,800+ sq ft with 3 bedrooms and 2 full baths. The space features soaring vaulted ceilings with exposed beams, wide-plank flooring, and an airy open layout. The top-floor primary suite opens to a private deck overlooking the garden, with potential for future roof deck access. Previously rented for $7,000 and now delivered vacant, it presents an ideal opportunity for owner-occupiers or premium rental income. Unit 2 (2977) is a charming 1-bedroom garden flat with direct outdoor access, currently tenant-occupied and offering immediate income with long-term upside through renovation. Unit 3 (2979) is an approximately 600 sq ft commercial storefront, leased and providing steady income, with strong visibility in a vibrant, high-foot-traffic corridor. This property works equally well as an investment or for buyers seeking to live in the penthouse while collecting income. Surrounded by some of San Francisco's best dining, cafes, and culture, and with easy access to transit, BART, and major commuter routes, this is a standout opportunity in one of the city's most desirable and evolving neighborhoods.
