    About this House

    Rarely available, this 8,190 SF vacant homesite sits along a deep water canal on Duck Key, with open ocean views that are simply priceless. The lot already includes a concrete dock, boat lift, and seawall, giving boaters immediate deep water access without the wait or expense of new construction. That same seawall will provide lasting storm and wave protection for whatever home is built here.

    Because a home previously stood on this site, the lot is ROGO exempt, meaning you can build without competing in Monroe County's growth ordinance lottery, a rare and valuable advantage in the Florida Keys.

    Located next to Hawks Cay Resort, residents enjoy easy access to dolphin swims, dining by a Michelin rated chef, and a full service marina. Duck Key sits centrally in the Middle Keys, close to luxury restaurants, the Grassy Key sandbar, deep drops for offshore fishing, clear Bahamian like waters, nearby reefs for lobstering and reef fishing, and the Islamorada Humps for tuna.

    Weekly rentals are not permitted on the island, preserving a quiet, residential feel with more full time locals than tourists. Bring your builder and bring your vision, this is a rare opportunity to create your dream home on one of the best kept secrets in the Keys. Schedule a viewing today.
