Key Colony is a large oceanfront condominium community on Key Biscayne, located along Crandon Boulevard with the Atlantic Ocean directly to the east. The community includes 1,179 homes across several condominium subdivisions and is known for its expansive landscaped grounds, coastal setting, and access to a range of recreational amenities.
Key Colony is not gated and sits in a convenient part of Key Biscayne, close to beaches, parks, local shops, restaurants, and everyday services. The Rickenbacker Causeway provides the primary connection between Key Biscayne and mainland Miami, making destinations throughout the Miami area accessible from the island.
Key Colony consists of four independently operated condominium communities: Tidemark, Oceansound, Emerald Bay, and Botanica. Together, these buildings make up the larger Key Colony residential development along Crandon Boulevard.
The community was designed with a strong connection to its oceanfront setting. Landscaped areas, distinctive architecture, and proximity to the beach give Key Colony a recognizable presence on Key Biscayne. Because each condominium operates separately, association fees, building rules, amenities, and ownership requirements can vary from one property to another.
Key Colony was developed during the late 1970s and early 1980s as Key Biscayne continued to grow as a residential destination. Developer Fritz Scharenberg was responsible for the development, which introduced four distinct condominium communities to the oceanfront portion of the island.
The four buildings—Tidemark, Oceansound, Emerald Bay, and Botanica—were developed as separate condominium communities while sharing the broader Key Colony setting. The development is also recognized for its distinctive architecture and extensive tropical landscaping.
Key Colony offers a combination of community-wide and individual condominium amenities. Access to specific facilities can depend on the condominium association and the residence.
Individual buildings may have additional amenities, including fitness centers, spas, recreation rooms, and building-specific pools or services.
Each condominium association has its own governing documents, fees, rules, insurance requirements, and maintenance responsibilities. Buyers should review the current documents for the specific building and residence before purchasing.
Ocean Village Key Biscayne — Another condominium community on Key Biscayne, with residences near the Atlantic Ocean and the island’s beaches and recreational areas. It offers a different condominium setting while remaining close to Key Colony.
Ocean Lane Plaza — A located along Ocean Lane and provides another established condominium option on Key Biscayne. Its location places residents near the beach, local recreation, and the central areas of the island.
Ocean Drive Manor — A smaller condominium community along Ocean Drive. It provides another residential option near the Atlantic shoreline and other Key Biscayne amenities.

Key Colony is located along Crandon Boulevard on Key Biscayne, Florida, directly adjacent to the Atlantic Ocean. Its location provides convenient access to the island’s beaches, parks, restaurants, shops, and recreational facilities. Mainland Miami is accessible via the Rickenbacker Causeway.
No. Key Colony is not gated. Individual condominium buildings may have controlled entrances, security measures, or other access procedures, but the larger Key Colony community is not a gated subdivision.
Key Colony consists of four condominium communities: Tidemark, Oceansound, Emerald Bay, and Botanica. Each operates as its own condominium association. As a result, fees, rules, building amenities, and ownership requirements can differ between the four communities.
Key Colony offers amenities that include private beach access, swimming pools, tennis courts, landscaped grounds, recreational areas, and a lap pool. Some individual condominium buildings also have their own fitness and recreation facilities. Access to particular amenities depends on the applicable condominium association and property.
Buyers should review the specific condominium association rather than relying only on information about the larger Key Colony community. Association fees, assessments, reserves, insurance, rules, and building-specific amenities can vary between Tidemark, Oceansound, Emerald Bay, and Botanica. Current condominium documents and financial information should be reviewed as part of the purchase process.
