A fire that gutted most of a three-story apartment complex was caused by an outdated heating system, fire officials said Monday.
The Superior Apartments, 302 S. Second, caught fire early Sunday. Flames spread quickly through the upper floors of the building and forced 15 people to evacuate.
No one was injured in the blaze, but the building was considered a total loss, sustaining more than $250,000 in damage.
Sandpoint Fire Chief Don Keck said it appeared the fire started in a second-floor apartment on the northeast corner of the complex. Investigators said they believe the fire was caused by a hot water boiler system used to heat the building. The fire is being ruled accidental.
