QUINCY (WGEM) -- A multi-unit house on Quincy's north side was damaged by fire Tuesday morning.
Investigators say the fire was contained within 30 minutes of crews arriving on scene.
Quincy Fire Deputy Chief Steve Salrin said the tenant who lived in the attic unit called for help after she returned to home to the fire at 635 Spruce St. just after 6 a.m.
She was able to get out of the house uninjured, and no one else was inside.
Deputy Chief Bernie Vahlkamp said no one rented the first floor unit.
He said there was evidence of people going in and out of the first floor space, including fresh food, but that likely had no bearing on the cause of the fire.
He said crews were able to determined the fire started in the attic.
Fire investigators later reported the fire was caused by electrical problems in the ceiling of the second floor.
Fire officials said the home had water damage throughout, and fire and smoke damage in the attic.
He said the home was salvagable, but would likely require a new roof.
