ATF officials responded to the fire scene at an abandoned building at Park Boulevard and Empire Street.
The fire broke out just before 8:00 p.m.
The 30,000 square foot commercial property had faded lettering that read Royal Auto Upholstering.
There's no indication yet how this started, or if it's connected in any way to three larger fires over the past two weeks.
It took fire crews a little more than a half hour to put the blaze under control.
No injuries were reported.
