The heavily-involved blaze on Harrison Street near Myrtle Avenue began as two alarms at around 9:15 a.m.
Heavy fire in the rear of the building eventually began consuming the rest of the 2½-family house -- eventually blowing through the roof -- while spreading to two others.
The blaze appeared knocked down a couple of times before eventually being declared under control around 11 a.m.
A firefighter sustained what was characterized as a minor injury. Reports of a rescue couldn't immediately be confirmed.
Mutual aid responders, either at the scene or in coverage, included firefighters from Carlstadt, Clifton, East Rutherford, Garfield, Hackensack, Paterson, Rutherford and Wallington.
