A man, who was on the top floor, was taken to a local hospital. His injuries are not life-threatening.
"He was conscious and alert, walking, didn't have any obvious injuries," CFD Assistant Deputy Commissioner Mark Nielsen said.
Everyone else in the home was able to get out, fire officials said.
Because of the extreme heat, firefighters were rotated. They got the fire under control around 4 p.m.
"In this kind of heat, it's always an issue. We have to get firefighters out of their bunker gear, that they wear for their protection because it really takes a toll on them. It dehydrates them, and we have to get extra water in them. Literally, about 15 minutes in this kind of gear is their limit. And we have to rotate people constantly," Nielsen said.
