First thing is to find out WHO does the inspection and enforcement. Here in FL you may wind up dealing with either the state or the county. If, for example, you "rent" your commissary space from a non-profit or church (ie. VFW) then you'd fall under the county inspectors. If you rented from a catering truck central commissary or a restaurant, you'd be inspected and such by the state inspectors.
I found out a ton of info from both the state website and the county. They are quite similar (duh!) and then I spent about an hour with an inspector and her supervisor going over the pages for "mobile food sevice" and catering. They were quite helpful and I asked some questions that had them scratching their heads, too.
