Fires damaged residences on Price and Vesson avenues Sunday, and one of them displaced six people, firefighters said.
Trucks were dispatched about 7:40 p.m. to 2501 Vesson Ave., where an attached shed was aflame.
Fire spread up the side of the two-story building and into a bedroom in a second-floor apartment and the attic, Deputy Chief Chris Iannuzzi said.
Firefighters called the Red Cross to help three adults and three children find places to stay, Iannuzzi said.
Never miss a local story.
Earlier, firefighters found smoke and flames coming out of an apartment in a one-story building at 403 Price Ave., the chief said.
That fire was reported just after 5 p.m.
No one was home at that apartment, Iannuzzi said.
Investigators were trying to determine how both fires started, he said.
