Good catch & good idea to check. Google maps for "Georgia Fire & Rescue Supply" shows an office location downtown, which streetview shows is a Publix supermarket and Walgreens. But that image is from Dec 2018.
The image you linked is the official business address (per a link in another reply) and it looks like a house, but your street view image is dated 2015.
Either location could have been bought/repurposed/expanded over the last few years. Worth some more DD in case it's people in a house running an internet mail order thing with a mailbox in a supermarket office-closet. The supermarket is sus because there'd be no way to store vehicles and bigger equipment there, it would need to be a garage. The house address has room for garages and equipment.
How about showing the full view where it is obvious that the connected and adjacent property is the business. They probably use the house (hence the handicapped accessible ramp) as the office and the warehouse is for the distribution activities.
