In 2016, "The Guardian" reported that the average SRO rents in San Francisco's Chinatown are increasing from $610 in 2013, to $970 in 2015 (the average rent for all rental housing was $3,907). The increase in SRO rents is due to the shift away from renting to Chinese immigrants towards "college graduates, single adults and white people". In 2016, about 60% of San Francisco's supportive housing tenants lived in SRO hotels. Newspaper reporters found "chronic maintenance issues, health code violations and frustrated residents" at some of these SRO hotels, typically built a century ago, including the Crosby Hotel in Tenderloin, which had "vermin infestations", no power, leaking pipes, and an elevator that was unreliable. Following numerous complaints, the owners of the Crosby Hotel spent $700,000 to repair and upgrade the building. The problems in the city's old SRO hotels are "old buildings with aging infrastructure filled with traumatized or dysfunctional people who sometimes can be destructive or neglectful through hoarding, attracting vermin or willfully damaging property". The Henry, another SRO hotel, is also being improved, with staff giving it new paint, an atrium area, WiFi and computers.
