Guests of a party to celebrate the three-year anniversary of 20 Mission, a co-living house, dance and listen to a DJ playing music using silent disco headphones in the building’s courtyard during the party in San Francisco, Calif., on Saturday, March 28, 2015. Around 40 people live in the building, which is a former single room occupancy hotel that had been vacant for several years before being turned into the co-living space. Many residents are start-up entrepreneurs and the community is a mix of temporary occupants and people who have made the space their home on a more long-term basis.
