Community Key Colony Beach

Key Colony Beach is located at mile marker 53.5 on US Highway 1, which is known locally as the Overseas Highway. The city, called the “Gem of the Florida Keys,” is on an island just south of the Overseas Highway connected via a causeway with a very small bridge.


The majority of residences are on canals with quick access to the Gulf or Atlantic Ocean or have ocean views which make the city ideal for fishing and boating activities. In addition to the residences, there are many businesses and recreation in the city, including restaurants, a charter fishing fleet, marina, boat rentals, clothing store, gift shop, dive and tackle shop, liquor store, gas station, convenience store, hotels, 2 playgrounds, bocce courts, pickleball courts tennis courts, shuffleboard, and a 9-hole par-3 golf course.

The city was founded in the early fifties by developer Phil Sadowski, who began dredging around the island, adding to its size and increasing its height to six feet above mean sea level. The city was incorporated in September 1957, and is situated on 286 acres with approximately 1,400 units of housing. Key Colony Beach is governed by five city commissioners elected for two-year, staggered terms. City elections are non-partisan and are held each year on the 2nd Tuesday in March. Thirteen employees assist the city commission including a staff of four in the city clerk’s office, a five-member police department, and a staff of four in the building/public works department. Traditionally, the Mayor also serves as City Administrator, supervising staff and ongoing activities on a day-to-day basis.

Key Colony Beach: An Overview

Key Colony Beach

Key Colony Beach, along with Key West, Marathon, Layton, and Islamorada, make up the five municipalities of Monroe County. Its nearest neighbor to the north across the Overseas Highway is the City of Marathon. Attaching Key Colony Beach to the Overseas Highway is the Sadowski Causeway – the island’s main artery which serves as its sole entry and exit point.

Spanning only 0.65 square miles with 0.44 square miles of it consisting of land, Key Colony Beach, FL is among the smallest municipalities of the county. However, the homes for sale here are among the most luxurious that you will find in the Middle Keys. Sought after primarily for their waterfront location, these houses for sale in Key Colony Beach, FL attract families wanting to have a second home in the tropics, investors wanting to cash in on the surge of tourist arrivals on the island, and snowbirds who prefer the warm sunshine on winters down south instead of the freezing temperatures of the north.

The basic facts

The Florida Keys are largely known for being a popular tourist hub, given their strategic location in the midst of the Gulf of Mexico and the Atlantic Ocean. They offer a lovely coastal setting and a plethora of activities both on land and offshore. However, even in their relative remoteness, they still manage to provide not just simple creature comforts but top-notch shopping, dining, and recreation options. That’s why the tourists always come over to visit, and their constant presence on the islands becomes the primary driver behind the remarkable quality of life in the Keys – from the economy to the real estate.

Key Colony Beach, just like the rest of the Keys, also has the tourism sector serving as a major influence in its growth. This influence extends to the real estate scene, where many homes on the island consist of vacation rentals. That said, a substantial chunk of the homeowner profile (31.5%) is also made up of seasonal residents who rent out their homes to tourists during peak travel seasons. Permanent residents, meanwhile, comprise 68.5% of the total Key Colony Beach households.

Even as the U.S. Census estimated Key Colony Beach’s population size at almost 800, this number may rise and fall depending on the season. Off-seasons are the times when the island is generally quieter and its permanent residents congregate in areas usually swarming with tourists. Their beautiful beaches become theirs to enjoy fully and fishing in or exploring the open sea becomes more relaxed and peaceful.

Most businesses in Key Colony Beach are aligned with the hospitality industry, serving everyone – whether tourist or local – on the island. Those who do have jobs on the island can just walk to their respective places of work as Key Colony Beach is a walker’s paradise. It’s also significant to note that almost 14% of employed residents on the island work remotely which, according to, is quite high in comparison to the rest of the county.

The neighbors

Key Colony Beach, as well as the rest of the Florida Keys, is almost exclusively surrounded by the ocean. As it is set in the Middle Keys, the waters surrounding KCB belong to the Atlantic expanse. These waters provide great boating opportunities and reefs to explore.

It’s not difficult to find urban conveniences when you’re living in or visiting Key Colony Beach as you have the cities of Marathon and Islamorada to turn to for anything from the hottest nightspots to medical facilities and good schools. As mentioned earlier, you only need to cross the Overseas Highway to get to Marathon. Islamorada is farther out with an almost 30-mile stretch between it and KCB but it’s an exciting urban hub with even more options for dining, shopping, and recreation, considering its proximity to the Florida mainland.

The history

In the early 1950s, Key Colony Beach was known simply as Shelter Key, a 97-acre island off the coast of Florida.

By 1957, Phil Sadowski took charge of developing the area to increase its height and size, essentially mitigating the occurrence of flooding during high tides. Though there were discussions to incorporate the island with Marathon, Shelter Key was recognized as its own island after a landmark decision by the Florida Legislature. In turn, this small, independent island came to be known as Key Colony Beach in 1957.

In 1960, the municipality was badly affected by Hurricane Donna but was fortunately granted funding to rebuild. While it took some time for real estate prices to stabilize and improve, it eventually grew into the upscale neighborhood we know today.

Sadowski Causeway, the main road into the island, got its name from KCB’s prime developer. The small island transformed into an exclusive, must-visit community, with a variety of hotels and restaurants to entertain tourists during peak seasons. Key Colony Beach, FL also has a good number of homes for sale to choose from for residential or investment purposes.
