According to KTIV-TV, the fire department reported Thursday that a valve in the laundry room was left open by a repairman. Gas vapors filled the home and were ignited by a heat source.

The homeowner, Cuong Phung, his three children and his mother-in-law escaped without serious injury.

City officials have red-tagged the home an uninhabitable because of the damage.
