Started mine about three years back, it really does depend on what state you’re in. Mine was a basic retail license + a health/safety inspection and that was it, but my buddy in a neighboring state needed a permanent bond and a bunch more paperwork. Definitely do your homework on your state’s ag/fire marshal office before you sink money in.

Also don’t sleep on the insurance part – a lot of the tent wholesalers won’t even talk to you without liability coverage. That caught me off guard at first.
