A fire at a fourplex in Alderwood Manor Thursday morning injured one man and displaced 14 residents.

Dispatchers received multiple calls at 11:40 a.m. reporting smoke and flames coming from the two-story, four-unit building in 20400 block of 28^th Ave. W in unincorporated south Snohomish County east of Lynnwood.

“Firefighters treated a man who was exposed to smoke and flames. He was transported by medic unit to Swedish/Edmonds Hospital. His injuries did not appear to be life-threatening,” said Leslie Hynes, public information officer for Snohomish County Fire District 1. “Five people safely exited the burning building.”

Smoke was visible as firefighters approached the scene. The first crew to arrive quickly called for a second alarm to bring in more resources to contain the flames, which had already engulfed the back wall of two units. About 40 firefighters from Fire District 1, Lynnwood and Bothell were on the scene at the peak of the fire. They had the fire under control within 20 minutes, but remained on the scene throughout the afternoon dealing with hot spots.

The fire caused heavy damage to two of the four units. Other units had smoke damage. All four units are uninhabitable as a result of the fire. A total of 14 residents – including six children – have been displaced. Support 7 and Red Cross are providing assistance. None of the residents had insurance.

The cause of the fire remains under investigation by the Snohomish County Fire Marshal’s Office.
