A private pool is close to standard on Key Biscayne houses, whether the house is a new two-story build in Tropical Isle Homes, an elevated Mediterranean home in Biscayne Key Estates or a canal house in the Cape Florida sections, and Mashta Island homes are part of the mix as well. Salt air and year-round use are hard on equipment, so ask for the age of the pump, the heater and any screen enclosure, and for the permit history of the pool itself. If children will live in the home, check that the barrier meets Florida's residential pool safety rules. On a rebuilt lot, confirm that the pool was inspected and closed out along with the new house, because an open pool permit on Key Biscayne surfaces in the lien search at closing.
