Firefighters responded at about 2:52 a.m., according to an email from Puget Sound Fire spokesperson Pat Pawlak.
Seven fire apparatus responded along with two command vehicles and three support vehicles, Pawlak said. In addition to Puget Sound Fire, Valley Regional Fire Authority, King County Medic One, Kent Police and the Zone 3 Fire Cadets also responded.
“Firefighters extinguished the fire in approximately 45 minutes,” Pawlak said. “There was damage to the roof structure and interior damage due to removing the sheetrock ceiling for fire extinguishment.”
There were no injuries.
Pawlak said the cause was determined to be incendiary.
“An incendiary fire is a fire that is started but not necessarily a crime,” Pawlak said. “An example is a cooking or warming fire.”
Pawlak said the investigator does not know why the fire was started or who started it, but he could see materials that had burned outside and spread from the parking lot to the building.
It is not considered arson, which is a crime, because the fire was not intentionally set to start the building on fire, Pawlak said.
