Looks like it's a non-issue in Florida.

Paul Hargis sought a special exception use permit to sell guns from his home on Hague Court, a permit the Planning and Zoning Commission had approved in mid December. Residents concerned about the safety and residential nature of their neighborhood urged county commissioners to hear the case, and they agreed.
County Attorney Garth Coller strongly cautioned commissioners about their decision, explaining that state law preempted local governments from establishing any limits on gun use or sales. A provision levies fines of up to $5,000 against public officials who violate the law.
"Never have I seen a more crystal clear preemption in my life,'' Coller told commissioners. "It's crystal clear (state lawmakers) don't want any fingers in this subject.''
