Jacksonville
Jacksonville-St. Augustine
Two-county barbell. Mainland Jacksonville (Duval) is YELLOW with cheap entry + Mayo Clinic MTR demand floor. Jax Beach is the ADR engine ($293 ADR / 58% occ). St. Augustine HD is functionally closed (HP-1 = monthly minimum) but St. Augustine Beach + unincorporated St. Johns (Ponte Vedra) ride The Players Championship March surge. Atlantic + Neptune Beach are RED.
FL preempts outright bans, but pre-2011 ordinances grandfathered. Neptune Beach + Atlantic Beach have grandfathered prohibitions on STR <90d. Jacksonville (Duval) requires registration but allows STR by-right where residential is allowed. St. Augustine HP-1 (Historic) caps at one rental per month (functional ban). St. Johns County permits with 10-guest cap.
