That’s when they told her to run.
Martinez ran to the fire department, which was across the street, and began to bang on the doors as she called 911.
Firefighters were able to extinguish the flames in about 10 minutes, but the damage is estimated to be about $200,000.
Boston 25 News also learned that several firefighters suffered minor injuries, but are all expected to fully recover.
There were eight adults and two children in the building, including Martinez and her parents.
They were all forced to find another place to sleep overnight, but are all thankful of the 11-year-old’s actions.
The cause of the fire remains under investigation.
