Two teens called in fire at about 1 a.m.
Tualatin Valley Fire and Rescue responded to a fire at 11795 S.W. Tualatin Road at 1:12 a.m., Thursday morning.
When crews arrived, one of the garages attached to the five-unit townhouse was engulfed inflames.
Firefighters were able to keep the fire from spreading to other units, while ensuring that the occupants of all five units had been evacuated.
The call came in from two young adults who were awake at the time of the fire. They reported having noticed an "acrid" smell from the second level of their townhouse, according to TVF and R spokesman Walt Peck.
Shortly after, they heard what they thought was the garage door opening.
The two youths walked downstairs, Peck said, thinking they would be greeting a family member coming home from work, but when they opened the door leading into the garage and found thick smoke covering the garage floor, and the glow of a flame.
By the time TVF and R arrived on the scene, Peck said, the pressurized flames had blown out the front door of the garage.
One townhouse sustained significant smoke damage, while a second had minor smoke impacts, Peck said.
Residents of all five townhouses were temporarily displaced as utilities were shut off. Nine adults, three children and a cat have received shelter assistance from the Red Cross.
No one was harmed in the fire.
A TVF and R fire investigator is currently investigating a cause for the fire.
