Firefighters responded after 9:30 a.m. to a house on Dukhobar Road, near Crow Road and West 11th Avenue.
The fire marshal is still investigating the cause of the fire, but the people living there think it was an electrical problem.
The three people renting the house were inside the home at the time. One of them woke up, saw flames and tried to put them out, but then got everyone out of the house. No one was hurt.
The property owner thinks the house is a total loss.
