A garage fire that occurred in the 22800 block of Northeast Union Hill Road in unincorporated King County outside of Redmond has been determined to be arson by investigators.

Sgt. Cindi West with the King County Sheriff’s Office said the fire occurred around 12:30 a.m. on Monday and was contained to the garage, which is not attached to the house.

West said Tuesday morning that the garage and everything inside, including two cars, were declared a total loss. No one was home at the time.

West said the fire is still under investigation and is unable to release any more details other than that it was intentionally set.

“It’s an arson, but nothing  has been released at this point,” she said.

About 18-20 firefighters from the Redmond and Duvall Fire departments, along with Eastside Fire and Rescue responded to the fire, which had fully engulfed the garage by the time firefighters arrived, according to Redmond Fire Cap. Don Sanderson.

Sanderson said firefighters could smell a gasoline odor when they arrived. One firefighter did injure his knee while battling the blaze and was transported to a local emergency department as a precaution. Sanderson called the injury “minor” and said the firefighter is expected to make a full recovery.
