A fire nearly destroyed a house on the 2700-block of Eaton Street on Missoula's south side. No one was in the house at the time and no one was injured.
It was reported about 11:30 Tuesday morning.
Fire investigators believe the fire started in the basement.
"It was leading to the main and upper story," said fire investigator Adam Sebastian. "We got here and it was a fully-involved fire."
Missoula firefighters arrived on the scene late Tuesday morning to find smoke coming from all sides of the home, which appears to be being remodeled.
