Investigators are at the scene this morning trying to determine the cause.
Smoke and flames were first spotted at Auburn Way South Storage, 917 Auburn Way South, about 6:30 p.m. By 8 p.m., the blaze had been upgraded to a four-alarm call and more than 70 firefighters from multiple agencies responded.
A Metro bus was brought in to use as a cooling station for firefighters, who were rotated in and out of the rotation due to the extreme heat.
The facility houses 11 storage buildings. The fire was contained to one building, which contained 105 units. Twenty were not being rented at the time of the fire, according to the facility’s owner.
Firefighters doused the flames by 11 p.m., Valley Regional spokeswoman Kimberly McDonald said.
It took longer to extinguish the blaze because the building was built before city code required sprinklers, she added.
One injury was reported to a firefighter who suffered a finger laceration.
