Private Islands in South Florida: A Buyer’s Guide to the Keys, Biscayne Bay, and the Island-Address Alternative

Private-island shopping in South Florida sits at the intersection of romance and regulation. Inventory exists, but it is thin and often marketed through portals and boutique channels; pricing spans widely, and the true differentiator is not just shoreline or sunset exposure, but what you can legally build, dock, insure, and maintain. This guide outlines the micro-markets most often associated with “island living” in the Florida Keys and Biscayne Bay, then translates the state’s ownership and permitting realities into a due-diligence framework. Finally, it offers a pragmatic option for buyers who want the island feel with a more predictable operational burden: the island-address residence in Miami’s most refined waterfront buildings.
