The flames erupted somewhere on the second floor of the building on West 91st St. near Broadway just before 6 p.m. Friday.
All residents got out safely. They say smoke quickly filled the hallways and even their homes.
"Luckily I was in the staircase and there was other people coming down and they told me that there was a fire, but you could smell like all the smoke," said Leah Estrada.
The cause of the fire is under investigation.
