A three-alarm fire engulfed four buildings in the vicinity of 17th and Valencia streets and displaced at least 20 residents, according to the Red Cross.
The fire that began at around 6 p.m. was under control as of 8 p.m., but two firefighters and one resident were injured, according to Patricia Peper of the Red Cross. The extent of their injuries is unknown at this time.
Peper added that the displaced residents have found shelter with family or friends, with the exception of a family of four and their pet. They will most likely be checked into a hotel south of San Francisco because the Outside Lands music festival has caused a shortage of vacancies in the city, she said.
Emergency in SF reported earlier that the fire was upgraded because of its complexity, and dozens of firefighters have responded to it. The cause of the fire is unknown.
Stay tuned for updates.
