Update 2, 8:10 p.m.

The fire at N Fessenden Street and N Oswego Ave is under control at 8:10 p.m.  Crews are still on scene and, according to Public Information Officer Paul Corah, will probably be there all night to make sure all hot spots are extinguished.

Portland Fire & Rescue was called to the scene at 6:22 p.m.  The fire rapidly extended into the building's cockloft and facade, and a second alarm was called at 6:39 p.m.  A few minutes later, the incident commander ordered all firefighters out of the building when crews reported that heat was building up inside and the fire went through the roof.

Nine engines, two trucks, and a rescue unit responded to the fire.  An air unit and rehab unit supported the firefighters.  About 60 personnel responded, including safety officers and investigators.  Investigators state that it is unlikely that they will be able to enter the building before morning.
