The downtown Everett building where a woman died Sunday in an apartment fire had been condemned and work was underway to fireproof the stairwell.
But city spokeswoman Meghan Pembroke said Monday the fire was apparently unrelated to the work.
Pembroke says the city had ordered the work Nov. 20 and residents were allowed to stay in the five-story Hodges Building while it continued.
The cause of the fire is under investigation but police spokesman Aaron Snell told The Daily Herald there were no signs of a crime, although arson investigators were involved in the work.
The two-alarm fire broke out before 7 a.m. in the 90-year-old building. Firefighters found the body. The Red Cross is helping residents who were displaced because utilities in the building were shut off.
