Fire crews battled the blaze at the shop at the corner of North 7th and Emerald streets in Harrisburg starting around 5 p.m., emergency dispatchers say.
Multiple vehicles in a lower level caught fire, keeping half a dozen crews on the scene for hours, according to releases from the various fire departments called.
Cars being moved from the parking lot to allow departments access possibly damaged the hose as many vehicles drove over the Harrisburg Bureau of Fire's hose, according to multiple fire officials accounts from the scene.
Hazmat crews were called to help mitigate chemicals from leaking into a nearby creek, dispatchers say.
One employee at the shop suffered minor burns, Harrisburg Bureau of fire officials say.
The building was "a total loss," Chief Brian Enterline told reporters on Tuesday night.
The fire remains under investigation.
