I think someone should investigate why it took a year to permit this change of use from Credit Union to Residential Group Housing, which should be Principally Permitted in the Use District C-3-G of the address at 12 Mint Plz. According to the sfchronicle article linked, “James Stallworth, CEO of Brownstone Shared Housing, said the city’s planning department was unresponsive for around nine months as the company sought to bring the project up to code.” But sfplanning disputed this: “Dan Sider, the planning department's chief of staff, said claims that the department was unresponsive were “utter nonsense” and said Stallworth only filed an application in July after “months of noncooperation.”” So which was it? Is San Francisco still failing to approve housing in a timely manner, or did the Brownstone drag thier feet?
