Malden firefighters responded to a fire at 68 Thatcher St. at about 9 p.m. Monday.
The fire was under a porch but spread to the walls of the house, according to Malden Deputy Fire Chief Leonard Dunn III.
Firefighters worked for more than an hour to extinguish the flames, he said.
No injuries were reported, and the occupants of the home were put up at a local motel.
The cause of the fire is under investigation, Dunn said.
Monday night was a busy one for Malden firefighters, as there was also a kitchen fire on Hurd Street and a medical emergency on the West End at about the same time, he said.
