Fire broke out in a Massachusetts Institute of Technology fraternity house on Bay State Road Friday night, forcing students in neighboring houses outside as temperatures dipped into the teens.

No one was injured in the single-alarm blaze, which started on the fourth floor of the Beta Theta Pi house at 119 Bay State Road around 10:30 p.m., according to Boston Fire Department spokesman David Walsh.

The house had been vacant for several days because the heat had not been working, Walsh said. He added that the house sustained about $100,000 in fire and water damage.

Five fire trucks blocked traffic on Bay State Road as students shivered on the sidewalks and sought refuge from the cold in the Towers lobby.

MIT graduate student Peter Russo, who was standing in front of 111 Bay State Road, said he saw what appeared to be a bay window in flames at the rear of the house.

“It looked like sparks were floating down across the row of houses,” he said.

MIT junior Christina Fry, who lives at 111 Bay State Road, said firefighters ordered the residents of her house to pull the fire alarm and evacuate.

College of Arts and Sciences sophomore Ata Gurpinar of 117 Bay State Road, who was clad in an undershirt and jacket, said he smelled smoke and was ordered to leave his house along with other residents.

Sal Sordillo, a Metropolitan College graduate student who lives at 115 Bay State Road, said he smelled smoke in his house around 10:30 p.m.

The cause of the fire is still under investigation, Walsh said.
