A small fire in the crawl space of a Haight Street bar believed to be under control later erupted in the walls and the attic, needing 45 firefighters to extinguish it.
At 2:30 p.m. Friday, four hours after the fire at Martin Macks Bar & Restaurant was reported and 3.5 hours after the single-alarm blaze was initially thought to have been controlled, firefighters were keeping a “fire watch” at the building, San Francisco Fire Department spokeswoman Mindy Talmadge said.
One fire engine and one truck were initially sent to the fire at Haight and Clayton streets and officials cut through the floor using saws to reach the flames, Talmadge said.
After the blaze flared up again, four engines, two trucks and 45 officials — including the fire chief — were dispatched.
The surrounding blocks were shut down and Muni re-routed.
