No one on the ground was injured.
Video from CBS New York showed the fire and police responding to a heavily wooded area.
Authorities arrived at the crash scene to find that fire had engulfed two industrial buildings near the Carlstadt Department of Public Works building.
Emergency responders spent more than an hour extingushing the fire, which police said torched cars in the parking lot. Police said 13 vehicles also were damaged.
Monday's crash of a Learjet approaching Teterboro Airport killed two crew members and damaged buildings in an industrial area.
The Learjet 35A, a twin-engine jet often used for business or personal travel, crashed at 3:30 p.m. about one-quarter mile (0.4 kilometer) from the busy hub for corporate aviation near NY, according to an emailed statement from the U.S. Federal Aviation Administration.
The cause of the crash is unclear, although some details have begun to surface.
In 2009, a plane taking off from Teterboro crashed into a sightseeing helicopter over the Hudson River, killing all nine people in the two aircrafts.
FAA records show the 1981 Learjet was registered to A&C Big Sky Aviation LLC of Billings, Montana, in 2014.
"It could have hit us and could have took our homes out", he said. According to CNN, the airport is used for general and business aviation.
It wasn't immediately known how many people were aboard the Learjet 35 when it went down around 3:30 p.m. Monday near Teterboro Airport in New Jersey.
The aircraft was being flown by Trans-Pacific Jets, a charter aircraft company based in Honolulu, the jet's owner said in an interview. That crash led to a series of safety board recommendations regarding air traffic controllers.
