Crews responded about 6:30 p.m. today to what became a two-alarm house fire in the 900 block of 112th Street South in Parkland.
The fire appeared to spread to a nearby house, Central Pierce Fire & Rescue Assistant Chief Randy Stephens said.
No one was injured.
He said the fire at both residences is under control, and that investigators are working to determine what caused it.
Utility crews were called to handle a natural gas leak at one of the homes, Stephens said.
A five-gallon propane cylinder involved in the fire was releasing gas, he said, but crews got the tank under control by cooling it down.
“Those are pretty scary situations,” he said.
He said strong winds probably drove the blaze.
“Wind-driven fires spread really quickly,” he said.
