Authorities are looking for the cause of a house fire in Cedar Falls.

Firefighters were called out at about 3:30pm Tuesday, to a residence in the 2000 block of Olive Street. A couple of tenants at the rental house called the fire department, saying they could smell smoke.

When fire crews arrived, they found the blaze on the porch, with flames moving into the interior of the home.

Cedar Falls firefighters were able to keep the blaze contained, and brought it under control in less than an hour.

No one was injured; the cause remains under investigation.
