Confused about local STR regulations

[Michael Ratterman]

Hi,

I am looking at a few areas in South Florida, it seems every local municipality has its own regulations.  One area is Palm Beach Shores.  The local municipality says no, however there are 100's listed in this area on AirBnB.  

Are these people simply ignoring the city? Do these local Muncipalities enforce the bans on STR's?

Thanks for any insights!
