A single-family house was evacuated in the Lakeview neighborhood after a floor partially collapsed.
Monday’s collapse rendered the building, in the 100 block of Margaret Avenue, unsafe for the five people living there, according to Ed Sweeney, deputy director of the San Francisco Department of Building Inspection.
The occupants included two young children, three members of two older generations of the same family and four cats and dogs, according to Sweeney.
Nobody was injured in the collapse.
Sweeney said he red-tagged the building because its first floor is no longer supported by a needed vertical beam.
“They’ll have to get an engineer’s report and a building permit to do the repairs,” he said. “It’s going to be a little bit costly — probably around $60,000 or $70,000.”
Water apparently had been seeping into the building’s ground-floor garage for years. That floor crumpled into a six-foot subterranean crawl space.
“The joist supporting the floor just collapsed into the crawl space,” Sweeney wrote in a statement following the incident. “It was dark and damp and because of the water seepage a perfect place for termites.”
All five residents arranged Monday night accommodations with family or friends, according to Red Cross spokesman Barry Gruber. Insurance is expected to cover the cost of repairs, he said.
