About a dozen Northeastern students were displaced early Monday morning when a three-alarm fire ripped through a mixed-use building on Westland Avenue.

Boston Fire Department Spokesman Steve MacDonald said about 75 firefighters responded to a call around 2:45 a.m. after a fire started in the building at 90 Westland Ave. The six-story structure houses Cappy’s Pizza and Subs, a laundromat and a convenience store on the first level; floors 2 through 6 are apartments primarily occupied by students from Northeastern and surrounding colleges.

“We know there was heavy fire on the top floor,” MacDonald said. “You can’t see it from the street, but the roof has severe damage.” Preliminary estimates by fire officials peg repair costs to the building at around $400,000.

MacDonald says it will be weeks before repairs can be finished to bring the building up to code and all apartments and businesses in the structure will be closed. No surrounding buildings were damaged by the fire.

Renata Nyul, Northeastern director of communications, said in an email that the Student Affairs “We Care” program at the university is organizing housing for displaced Northeastern students.

“We are helping the students with everything appropriate and necessary, including meals, information relevant to landlord/tenant responsibilities and letting faculty know of the students’ challenging situation,” Nyul said.

Nyul did not say how long the university would be offering housing and which residence halls were affected. Most students moved into on-campus buildings during the Labor Day weekend ahead of the first day of classes on Wednesday.

“The focus right now is to do what’s right based on each student’s individual needs and circumstances,” Nyul said. “We are making sure that we have beds for them, meals, support, counseling, etc. as needed.”

BFD officials are still investigating the cause of the Westland Avenue fire.
