Firefighters arrived to find flames coming from a home on Lake Shore Boulevard.
The fire apparently started in the carport just before 8:30 a.m. Residents said they heard an explosion and attempted to tackle flames with an extinguisher before firefighters arrived.
Two women who lived in the home and their two dogs made it out of the house safely.
It took about 25 minutes for firefighters to put the fire out. No surrounding homes were in danger.
The women said they will stay with neighbors while damage is accessed and the state Fire Marshal's investigation continues on how the fire started.
Alan Lesley, the homeowner who was not home when the fire started, said he thinks foul play is involved. He said a month ago someone broke into the carport and he roughed him up. At that point, Lesley said, the man said he'd be back.
In between that incident and the fire, Lesley said one of his cars was broken into. Both times, he filed a police report.
The state Fire Marshal's Office confirmed the fire did start in the carport, and it could be a case of arson.
