No one was injured in a Sunday morning house fire on Fairchild Street but the blaze did damage the home, according to the Baton Rouge Fire Department.

A rear wall of the house in the 1800 block of Fairchild Street caught fire with flames eventually spreading underneath the structure before it was brought under control just after 9:30 a.m., a half hour after firefighters arrived, Baton Rouge Fire Department spokesman Curt Monte said in a news release.

All three residents were home when the fire broke out but escaped uninjured, Monte said. Investigators estimated the damage to the house was about $29,000, including extensive damage to the rear wall and floor joist, Monte said.

The cause of the fire remains under investigation, Monte said, but investigators do not suspect it was arson.

The Red Cross came out to the home to offer assistance to the residents.
