A second-alarm fire broke out at Cabrillo Street and 16th Avenue in the Inner Richmond at 2:53 p.m. on Monday, the San Francisco Fire Department said.
One adult was rescued from the three-story complex and is in critical condition, officials added. One firefighter suffered minor injuries. The fire initially started as a first alarm but was later upgraded to a second alarm.
"It was originally located on the second floor with flames shooting out the second floor window of the [left] side of the building," a fire department spokesperson said, adding that the fire quickly escalated to the third floor.
The blaze also prompted an "avoid the area" warning, sent out by the San Francisco Department of Emergency Management. The fire department spokesperson added that it is still an active scene and it is currently not known how many people will be displaced from the building.
