Casey Key is the quietest expression of Gulf Coast luxury — an eight-mile barrier island south of Siesta Key where a single two-lane road runs beneath a canopy of live oaks and where almost every home sits on private acreage between the Gulf of Mexico and Little Sarasota Bay. There are no condominium towers, no commercial strip, and no through traffic to speak of; the island's defining amenity is the absence of everything that crowds the keys to its north.
Price Range: $3M – $20M+
Casey Key Market Overview
Casey Key trades on scarcity rather than volume. The island holds only a few hundred residences, and in a typical year a small handful change hands — which means pricing is set by the particular parcel far more than by any island-wide average. Gulf-to-bay properties, where a single owner controls beach frontage on one side and dockage on the other, are the island's most sought-after holding and are rarely marketed openly.
Buyers here are almost always second- or third-home purchasers who have already looked at Siesta Key and Longboat Key and decided they want more land, more privacy, and fewer neighbors. Because inventory is thin and turnover is low, the most consequential transactions on Casey Key are often assembled quietly between owners and representation long before a listing exists. That is the market we work in most often on this island.
Land value dominates improvement value on the Gulf side. It is common for a buyer to acquire a mid-century residence for the parcel beneath it and build new, which is why construction-readiness — coastal setback lines, elevation, septic and utility position — matters as much as the existing house when we evaluate a property here.

Living in Casey Key
Life on Casey Key is deliberately unhurried. Days are organized around the water — a morning walk on an unpopulated stretch of beach, a boat out the Venice or Midnight Pass side, an evening on the bayfront as the light goes flat over the mangroves. There is no island commerce, so residents drive north to Siesta Key Village or east to Osprey and Nokomis for provisions and dining.
The island's culture is private to the point of anonymity. It has drawn writers, executives and public figures for decades precisely because a Casey Key address does not announce itself. Homeowners tend to know their immediate neighbors well and the rest of the island barely at all — which is, for most people who buy here, the entire point.
Things to Do
- Walk the uncrowded Gulf beach at first light
- Cross the historic Blackburn Point swing bridge by boat or car

Casey Key FAQs
Frequently asked questions
Is Casey Key a private island?+
Casey Key is not gated, but it functions as one of the most private addresses on Florida's Gulf Coast. A single two-lane road serves the island, there is no commercial development, and most residences sit on large parcels behind mature landscaping. Access from the south is via the historic Blackburn Point swing bridge and from the north via Siesta Key.
What does a home on Casey Key cost?+
Pricing is parcel-driven rather than market-driven because so few homes trade each year. Bayfront homes with dockage generally begin in the mid seven figures, Gulf-front residences on acreage run substantially higher, and rare Gulf-to-bay estates that control both beach and dock frontage represent the top of the island's market. We advise clients on specific parcels rather than island averages.
Can you keep a boat on Casey Key?+
Yes. Homes on the Little Sarasota Bay side typically have private docks with lifts in sheltered water, giving quick access to the Intracoastal Waterway and out to the Gulf through Venice Inlet. Gulf-front homes without bay frontage generally arrange dockage nearby on the mainland or at Blackburn Point.
How far is Casey Key from Sarasota?+
The north end of the island is roughly 20 to 25 minutes from downtown Sarasota depending on the bridge, and about 15 minutes from Venice to the south. Sarasota Bradenton International Airport is a 35 to 40 minute drive.
