The four-alarm blaze broke out around 9 a.m. in the abandoned, boarded-up building on Fair Street near Straight Street.
It quickly consumed the upper floors of the 2½-story structure and eventually collapsed the roof.
All visible flames were knocked down within 90 minutes as firefighters continued to douse hot spots. A demolition crew was summoned to raze the building.
Among those providing mutual aid were firefighters from Clifton and Hawthorne.
A firefighter was taken to St. Joseph’s Regional Medical Center with an undisclosed injury.
