About Sunset Key

Sunset Key, a 27-acre private island off the coast of Key West, originated in the mid-1960s as a man-made landmass created by the U.S. Navy through dredging operations. Originally named Tank Island, it was intended to serve as a strategic Cold War-era fuel storage depot in response to the Cuban Missile Crisis. Although the Navy planned twelve large fuel tanks, only two were constructed, and they were never utilized for their intended purpose. In 1986, the federal government auctioned the island, leading to the dismantling of the tanks in 1988. The site was redeveloped in the 1990s, with the original, unused fuel lines repurposed to carry modern utilities. Renamed Sunset Key in 1994, the island evolved into an exclusive, car-free residential and resort community characterized by its privacy and distinctive architectural cottages.

The area functions as a quiet residential enclave defined by its pedestrian-friendly design and exceptional scenic beauty. With no heavy industry and limited commercial activity, the neighborhood maintains a calm, semi-rural character that prioritizes privacy and high-end aesthetic appeal. The demographic profile is notably diverse, attracting a mix of young adults, families, and retirees who value the island's seclusion and its well-maintained green spaces.

Prospective residents should consider the trade-offs associated with island living, including moderate flood risks and limited public pet amenities compared to the mainland. However, the area benefits from high levels of health insurance coverage and access to the well-funded Monroe County School District. This neighborhood is best suited for those seeking a secure, quiet, and highly accessible environment that remains connected to the broader Key West community while offering a distinct sense of isolation.
