Casey Key
A hidden barrier island of Old Florida estates between Nokomis and Venice.
Overview
Casey Key is a narrow, largely undeveloped barrier island connected by a swing bridge, known for its lack of high-rises, celebrity-favored privacy, and some of the most secluded beachfront real estate on the Gulf Coast.
Lifestyle
Private beach walks, boating and fishing from private docks, and an extremely quiet, low-key pace with almost no commercial development on the island itself.
Housing options
Waterfront single-family homes and estates, generally from $1.5M to $10M+, with very limited inventory.
Pros
- Extreme privacy and exclusivity
- No high-rise development permitted
- Gulf-to-bay lots on a narrow island
- Strong long-term value
Considerations
- Very limited inventory
- No on-island shopping or dining
- Swing bridge can mean waiting for boat traffic
- Flood insurance and construction costs are significant
- Public schools here are part of Sarasota County Schools, which earned an A from the Florida Department of Education for 2025-26, its 23rd A in a row. School zoning changes, so verify the assigned schools for any address with the district before you buy.
Lifestyle fit
Privacy-focused luxury buyers who want a true barrier-island estate without the density of Siesta Key or Longboat Key.
