Counties in Florida that allow full-time on own property?

We were looking to do this 3 years ago and found nothing. We even found land with a building we wanted to use, but could not live there fulltime with/without a building or even if we built something there. I have heard of the 5-acre rule in other states, but not Florida. I, too, heard a 2 counties in Florida that allowed it but never found it myself.

We elected to buy in a motorhome community which allowed us our 2 RV's, a 40' and a 22', 2 cars and a trailer. Down to just one RV now.
