How to find out whether a property can be used for an STR?

[Rick Dane]

I'm looking at different areas in Florida, I have used apps like AirDNA but I'm finding there are a lot of listings that don't seem to show up there that I see when I use Airbnb itself to look at listings for full house short term rentals. When I compare what I see in Airbnb to what I see when I look for houses for sale on Zillow it has become really confusing to try to understand which houses for sale may be allowed to be short term rentals (ones that allow stays under one month). I wasn't sure if there is a way to check this efficiently? The only option I have in mind is contacting realtors to have them check as they seem to be able to figure this out, however, as I haven't narrowed down my search to one city yet I wanted to avoid having to contact many different realtors if possible. I have generally decided to focus on the west coast of Florida though, assuming I can find something in that region in my budget range, in case that matters as well. Any advice is appreciated.

I realize it's possible to contact each city / county and ask for this info but this seems really time consuming as I think they would be slow to respond and not sure how they would feel if I keep asking them about a bunch of different houses.
