WEST JORDAN — An early morning fire caused heavy damage and displaced seven people, but no one was injured.

The fire started just before 2 a.m. in a garage near 3300 West and 9000 South. There were no vehicles in the garage, but there were plenty combustible materials such as boxes and other items being stored, said West Jordan Assistant Fire Chief Marc McElreath. A pool table in the garage was also destroyed.

Crews arrived to find the garage fully involved. Firefighters were forced to open the roof and prevented the flames from spreading inside the attached house.

A family of two adults and three children lived in the upstairs and another couple rented the basement, McElreath said. There were no working smoke detectors in the house.

"They were awakened by the smell of burning plastic. They were lucky," he said.

The fire was brought under control in about 15 minutes. Damage was estimated at $100,000. The garage was destroyed, and the house suffered some smoke, water and structural damage. The occupants will be staying with friends and relatives until it is fixed, McElreath said.

The cause of the fire was still being investigated Friday, but McElreath said the leading theory was too much cluttered material around a hot light fixture was ignited.
