Casey Key is a roughly 8-mile barrier island in south Sarasota County, running parallel to the mainland between Nokomis and Osprey, with the Gulf of Mexico on the west and Blackburn Bay and the Intracoastal Waterway on the east (Visit Sarasota County, 2026). It is reached by two bridges only: the historic Blackburn Point swing bridge, a hand-operated 1926 span at the north end, and the Albee Road drawbridge from Nokomis at the south, built in the 1960s (Wikipedia, Blackburn Point Bridge).
The island is almost entirely single-family and owner-occupied, with no high-rises, ranging from older beach cottages to large Gulf-to-bay estates. It is consistently among the most exclusive and private addresses on the Sarasota market, which makes condition, frontage, and elevation, not a headline average, the real drivers of value.
The 2024 hurricane season reframed the island. Hurricanes Helene and Milton flooded homes, toppled trees, drifted sand into houses, and damaged the road and shoreline, leading some owners to tear down and rebuild (Washington Post, October 2024). Sarasota County has since authorized a multiyear, FEMA-backed reconstruction of North Casey Key Road with a permanent seawall, targeted for completion in 2027 (Your Observer, October 2025).
The pitch is privacy and Gulf-to-bay living on a rare barrier island. The work is unglamorous diligence: the FEMA flood zone, base flood elevation, seawall and dock condition, wind and flood insurance quotes, and the access and erosion picture for the exact parcel, all read honestly before you fall for the setting.
