Key Biscayne, FL Homes for Sale

Key Biscayne is a village on a seven-mile barrier island in Miami-Dade County, Florida (ZIP 33149), connected to the mainland and Brickell by the Rickenbacker Causeway, and incorporated in 1991. Ponce de León named Cape Florida in 1513, and the Cape Florida Lighthouse, first built in 1825, still stands inside Bill Baggs Cape Florida State Park at the island's southern tip. Homes include oceanfront and bayfront condominium towers, townhomes, and single-family homes on residential streets, many of them first built by the Mackle company beginning in the 1950s. The Village is entirely within a Special Flood Hazard Area and participates in the National Flood Insurance Program's Community Rating System, and oceanfront parcels may sit seaward of Florida's Coastal Construction Control Line, so elevation, flood insurance, and permits should be reviewed before every offer. Crandon Park, with its Atlantic beach, golf course, marina, and the Marjory Stoneman Douglas Biscayne Nature Center, and Bill Baggs Cape Florida State Park take up much of the island.
