Five people were displaced Wednesday morning by a fire that broke out in a single-family house in San Francisco, according to fire officials.

The two-alarm fire at 475 Vienna St. was reported by fire officials at 12:15 a.m. on Twitter.

Both homes on either side of the house sustained light damage and there were a total of 16 residents from all three homes who were affected, according to San Francisco fire spokesperson Lt. Jonathan Baxter.

There were no reports of injuries.

The American Red Cross was responding to assist the displaced residents, Baxter said.
