Because the majority of streets in TV are public, "No Soliciting" signs at entrances are just a friendly suggestion/request and have no enforcement basis either by the developer or county.
The counties do require licensing for door-to-door sales activity. And it is enforceable.
Is there any real difference between the tossing of monthly newsletters in our driveways and someone hanging door-hangers? I don't think there is.
If you don't want sales reps/door-hangers you will need to have a "No Trespassing" or "No Solicitation" sign on your private property. Problem is that sign may be a violation of your TV covenants.
We have chosen to worry more about getting a decent tee time….
