86 Golden Gate Avenue is a ±4,726 SF downtown San Francisco development opportunity zoned C-3-G with a 120-foot height limit, offered at $3,000,000. The site's form-based residential density carries no fixed unit cap, and individual units may reach up to 4,000 SF, giving a future developer significant flexibility for a mid-rise residential or mixed-use program without a ground-floor retail requirement. The property sits within San Francisco's Downtown Adaptive Reuse Program and Revitalization Financing District, which waives inclusionary and impact fees and provides up to 30 years of incentive payments for qualifying downtown residential development — a meaningful boost to feasibility in a city facing a structural housing shortage. For buyers seeking a lower-cost, near-term path, the existing ±11,180 SF Category A historic building (built 1918, facade retention required) offers a renovate-and-reposition alternative for retail, creative office, or institutional use, while preserving optionality for future ground-up development. The location is among the most transit-connected in California — two blocks from the Civic Center / UN Plaza station serving every BART and Muni Metro line, with Market Street rapid transit, UN Plaza, and Union Square all within walking distance. Combined with active nearby redevelopment (including the 901 Market office-to-housing conversion) and potential assemblage with the adjacent 64 Golden Gate Avenue parcel, 86 Golden Gate Avenue offers investors and developers two distinct paths to value in the heart of San Francisco's Civic Center / Mid-Market corridor.
