A police officer and a witness spotted the fire early Friday morning at a home on Uhlan Court, off South Broadway near Red Mile Road.
We're told a mother and her two children live at the home, but weren't at home at the time.
When the police officer and witness arrived at the scene, they knocked on the front door of the home to see if anybody was inside.
They couldn't go inside because the fire was so bad.
Neighboring houses had to be evacuated, but weren't damaged.
No one was injured.
The investigation into what caused the fire continues.
