447 Minna

447 Minna, sometimes referred to as the historic Dempster Building or CAST 447 Minna, is a multidisciplinary arts and community venue in San Francisco’s South of Market (SoMa) neighbourhood. Located at 447 Minna Street, between 5th and 6th Streets near Powell Street BART, it offers around 1,700 square feet of flexible space including a black box theatre, conference room and box office within a 10,200-square-foot building at the heart of the 5M development.

The venue typically hosts small-scale performances, theatre, experimental work, film screenings, exhibitions, rehearsals, figure-drawing sessions, conferences, company offsites, workshops, pop-ups and community gatherings, and serves as the regular home for the SF Neo-Futurists’ show "The Infinite Wrench". Built in 1907 as the Dempster Building, it first functioned as a printing facility, later becoming a Hearst Corporation photo archive and test kitchen. Donated to the Community Arts Stabilization Trust (CAST) in 2019, it underwent major renovation from 2020 and reopened in March 2022 as an affordable arts and cultural centre focused on SoMa communities, particularly Filipino and LGBTQIA+ residents.
