Hackettstown firefighters had the fire extinguished within 45 minutes Sunday afternoon, said Fire Chief James Taylor.
The cause is unknown in what led a detached garage to ignite into flames Sunday afternoon in Hackettstown.
Fire Chief James Taylor said the blaze, which began shortly before 1 p.m., had started as a brush fire and spread to a fence and the detached garage at 127 Mountain Avenue.
Firefighters worked to keep the flames from spreading to the home, which was three feet away from the detached garage. Taylor estimated it took firefighters 30 minutes to get the blaze under control and 45 minutes to completely extinguish it.
There were no reported injuries. Taylor was unsure if the homeowners were home during the time of the fire.
Taylor said the garage was mainly used as a workshop area and was used for storage -- not vehicles. Nothing was flammable inside, he said.
The cause of the blaze remains under investigation by the Hackettstown Fire Department.
