A two-alarm fire in Potrero Hill on Thursday morning gutted one home and left two neighboring residences with considerable structural damage.
The fire began at 911 Minnesota Ave. at approximately 10 a.m., and spread to the two adjacent homes at 909 and 913 Minnesota, said firefighter Jim Bardem, who headed the response.
By the time firefighters arrived at the scene, 911 Minnesota Ave. was fully involved with flames, said Bardem. The blaze was totally contained by 11:43 a.m.
The fire displaced nine residents from the three homes, although no one suffered serious injury. The Red Cross is housing two of the displaced residents, while the rest are with family members
Fire department spokeswoman Lt. Mindy Talmadge said a man, whose name was not revealed, was home at 911 Minnesota Ave. at the time of the fire. He heard smoke alarms going off, but did not leave immediately, apparently because he was searching for his mother, who authorities believe was at church during the inferno, said Talmadge.
The man was transferred to San Francisco General Hospital, but was released later in the day with no serious injuries, said Woody Baker-Cohn of the American Red Cross.
The cause of the fire is under investigation, said Talmadge.
