PHOTOS: 3 homes catch fire in West Englewood blaze

CHICAGO (WLS) -- A firefighter was hurt and 18 residents were displaced after an extra-alarm fire in the city's West Englewood neighborhood.

The fire broke out at 1:10 a.m. Thursday in the 7300-block of South Paulina. The fire started in one home, then spread to the neighboring homes on either side, the Chicago Fire Department said.

Chicago firefighters called for an extra alarm due to weather and freezing conditions, however, frozen hydrants were not an issue, CFD said.

One firefighter was taken to Christ Hospital in Oak Lawn after he fell. He's in good condition and expected to be released, CFD said.

No residents were injured. Warming buses and the Red Cross were on the scene.

The cause of the fire is still under investigation. One homeowner says she smelled smoke before the fire actually started and that the fire department checked it out. Firefighters said they could smell burning plastic, but couldn't find the source of the smell and left. A short time later, the fire spread to the home and other homes.

The homeowner stayed at her mother's house nearby to be safe and was awakened a couple of hours later when she heard a commotion outside.

"I heard a lot of noise from the street, like ambulance and police sirens. I jumped up and ran to the door and saw police running to the house. I called out and said this is my house, my house, my house! They asked who's in the house now. I said nobody's there now, " said homeowner Janice Hooper.

Thirteen adults and five children were displaced by the fire.
