A two-alarm fire caused $100,000 damage today to a South Boston commercial building undergoing conversion into a Foodies Urban Supermarket, officials said.
The fire is believed to have started in the basement, but then traveled up the walls and into the roof of the one-story brick building at the 230 West Broadway, said Boston Fire Department spokesman Steve MacDonald.
A single sprinkler head nearest the flames did activate, but the sprinkler did not completely extinguish the fire, he said.
“The fire got above the sprinkler and into the wall, and traveled up a little bit,’’ MacDonald said. “Once it got into the walls, it was just hard to get at where the fire was. They had to open the walls and put a couple of holes in the roof.’’
The fire started in electric utility closet in the basement, officials said.
MacDonald said there were a large number of workers at the property at the time, but no injuries were reported.
