A row of Glendale Heights townhouses were damaged in an Tuesday afternoon fire that brought more than a dozen area fire departments to the scene.
Three homes were involved in the blaze, which caused extensive damage to at least one unit on the 1800 block of Hickory Lane, according to fire officials.
The fire broke out around 3 p.m., and was under control by about 4:30 p.m., officials said.
The fire spread from one townhouse to the adjacent homes to the north and south, leaving all three uninhabitable due to the damage, said Bloomingdale Fire District Batallion Chief Scott Koehn.
The cause of the blaze remained under investigation Tuesday night.
Koehn said no residents were home during the fire, and there were no reported injuries.
He said a natural gas line leading to the back of the home ignited, which fed the fire, but investigators were not sure if that was the cause.
There were no indications the fire was suspicious in nature, according to Koehn.
Firefighters from Carol Stream, Addison, Hanover Park, Roselle, Itasca, Lombard, West Chicago, Glen Ellyn, Winfield, Streamwood, Bartlett, Elk Grove, Bensenville and the Glenside Fire District assisted the Bloomingdale Fire District.
