Fire raced through a vacant Fair Lawn home late Wednesday afternoon.
The blaze broke out in the rear of the 1½-story Oak Street house around 4:45 p.m. and quickly spread, responders said.
Within minutes of firefighters' arrival, it went to three alarms.
All interior firefighters were removed and a defensive operation was ramped up, under cold, windy conditions that didn't make things any easier.
They still knocked the fire down in under an hour and declared it under control minutes later.
No injuries were immediately reported.
Firefighters from Saddle Brook, Glen Rock, Elmwood Park, Rochelle Park, Garfield, Hawthorne , and Paramus provided mutual aid either at the scene or in coverage.
The house, built in 1958, has a "For Sale" sign out front but was reportedly under contract.
Authorities were investigating, although they didn't suspect anything suspicious.
