Firefighters say it started Sunday afternoon in one apartment and almost spread to several others.
Luckily though, firefighters put the majority of the fire out in around 20 minutes.
But it left one apartment burned, and several other neighbors with smoke and fire damage at Newport Apartments off West Loop 250.
Investigators right now think it may have all started in the living room.
They also say it was the apartment's maintenence man's room.
No word on how many people have been displaced.
