A three-alarm fire in San Francisco's Castro District burned two buildings Saturday and displaced a dozen people, a fire lieutenant said.
Firefighters responded to a report of a working fire at 15th and Church streets around 4:10 p.m. Saturday, San Francisco fire Lt. Robert Lopez said.
The incident was quickly upgraded to a second alarm after crews found the fire burning between two buildings, and about 10 minutes later a third alarm was called. The blaze was under control at 5:23 p.m.
The fire caused an estimated $1 million damage to property and $250,000 to contents at a three-story building on Church Street, fire officials said.
A two-unit apartment building also involved in the fire sustained an estimated $100,000 in property damage and $50,000 in damage to contents.
A third building to the rear of the three-story building sustained water damage stemming from the fire.
The American Red Cross was called to assist 12 adults displaced by the fire, and the San Francisco Department of Animal Care and Control responded to care for a cat that suffered smoke inhalation.
No other injuries were reported.
A total of 104 firefighters responded to the blaze, fire officials said.
