Johnson City provided little new information Monday about why it attempted to shut off power at the Haven of Mercy homeless shelter last Friday. The city did provide a copy of an order issued by Chief Building Official Jeff Canon, which repeats a section of city code that states the chief building official has the authority to disconnect power and other utilities if they pose a danger to inhabitants. The order asks that service be disconnected from the property, located at 123 W. Millard St., until itâs cleared by a city inspector. Reached Monday afternoon, Canon directed a Johnson City Press reporter to the cityâs media relations department.
