The blaze erupted inside an empty Riverside Drive apartment near W. 82nd St. around 5:45 a.m. and quickly spread to adjoining apartments, the FDNY said.
Firefighters were seen pulling people out of a third-story window onto a tower ladder and down to safety.
There was no one in the home where the fire started, officials at the scene said. The flames were put out around 7:15 a.m.
Seven residents and five firefighters were taken to area hospitals, all with minor injuries.
