Waterfront on Key Biscayne takes three forms, and each trades in its own market. Along the Atlantic side, condominium buildings such as the Commodore Club, Casa del Mar and Island House sit on the beach itself, so much of this page is apartments with a sand view rather than houses with a dock. Behind the village, houses on the canals of the Cape Florida sections and on Mashta Island face Biscayne Bay. In oceanfront communities such as Key Colony, some units look west instead, toward the Miami skyline across the bay. Before comparing two Key Biscayne waterfront listings, confirm which water each one touches, because a beach building is judged on its reserves and milestone reports while a canal house is judged on its seawall, dock permits and elevation.
