What Casey Key is actually like
Casey Key is an eight-mile barrier island in Sarasota County, less than a quarter mile wide in places, with the Gulf of Mexico on one side and Little Sarasota Bay and Blackburn Bay on the other. A single winding two-lane road, Casey Key Road, runs its length beneath oaks, palms, and sea grapes. There are no high-rises and no commercial strip on the island itself.
Two bridges connect the key to the mainland: the 1920s-era one-lane Blackburn Point swing bridge from Osprey at the north end, listed on the National Register of Historic Places, and the Albee Road drawbridge from Nokomis at the south end. The island is unincorporated Sarasota County, and addresses carry Nokomis or Osprey.
The housing stock is nearly all single-family. It runs from mid-century beach cottages and renovated bayfront homes with docks to Gulf-front estates and rare parcels that stretch from the Gulf to the bay. A small cluster of low-rise condominiums sits near the south end by Nokomis Beach. Since the 2024 hurricanes, new elevated construction has been reshaping stretches of the island.
Public life concentrates at the south end, where Nokomis Beach — Sarasota County's oldest public beach — and North Jetty Park at Venice Inlet anchor the island. North of there, Casey Key settles into a quiet residential rhythm of driveways, dune walkovers, and dock lights on the bay.

Life in Casey Key
Life on Casey Key is organized around the water — beach on one side, bay and Intracoastal on the other — with daily conveniences a short drive away in Nokomis, Osprey, and Venice.
- Nokomis Beach, Sarasota County's oldest public beach, anchors the island's south end and hosts a long-running sunset drum circle, traditionally on Wednesday and Saturday evenings.
- North Jetty Park at Venice Inlet offers fishing, picnic shelters, and one of the Gulf Coast's few consistent surf breaks.
- Bayside homes front the Gulf Intracoastal Waterway along Little Sarasota Bay and Blackburn Bay, and Venice Inlet gives boaters direct deep-water access to the Gulf of Mexico.
- Casual waterfront dining sits at both bridge landings — Casey Key Fish House at Blackburn Point and Pop's Sunset Grill on the Nokomis side of the Albee Road drawbridge.
- Oscar Scherer State Park, the Legacy Trail, and Historic Spanish Point — now a campus of Marie Selby Botanical Gardens — are minutes away on the Osprey–Nokomis mainland.
- Downtown Venice is roughly 15 minutes away, downtown Sarasota about half an hour, and Sarasota-Bradenton International Airport (SRQ) under an hour by car.
What we watch for buyers in Casey Key
- Virtually all of Casey Key sits in a FEMA special flood hazard area. Budget for flood and windstorm coverage from day one, and request the elevation certificate early — it drives both insurability and premium.
- Hurricanes Helene and Milton (2024) damaged many island homes. On any resale, review the permit history, how repairs were documented against FEMA's 50% substantial-improvement rule, and whether the home now meets current elevation code.
- Gulf-front improvements — pools, seawalls, additions — typically require state permitting seaward of the Coastal Construction Control Line, which adds time and design constraints.
- Bayside water depths vary along Little Sarasota Bay and Blackburn Bay. Verify controlling depth at the dock, your vessel's draft, and the opening schedules of the two drawbridges before assuming easy Gulf access via Venice Inlet.
- Casey Key Road is a two-lane island road fed by a one-lane swing bridge at the north end, and the island sits in a coastal evacuation zone — factor storm-season logistics into ownership plans.
The Wave Estates Group in Casey Key
Casey Key transactions turn on details that never appear in listing photos: flood zone and elevation data, the permit trail behind post-2024 repairs, the FEMA 50% rule's effect on renovation plans, dock depths and bridge clearances, and Coastal Construction Control Line constraints on Gulf-front work. The Wave Estates Group, led by Valentina Kvamme and brokered by Preferred SHORE Real Estate in downtown Sarasota, works that due diligence line by line — coordinating elevation certificates, insurance quotes, and inspections before contingencies expire. The team times listings to the winter buyer season, works with clients in English and Russian, and covers the full Sarasota–Manatee–Charlotte coast, so Casey Key sellers get exposure beyond the island and buyers get honest comparisons with Siesta Key, Manasota Key, and the Venice keys.

Where is Casey Key, Florida?
Casey Key is an eight-mile barrier island in Sarasota County, Florida, set between the Gulf of Mexico and the Little Sarasota Bay–Blackburn Bay stretch of the Intracoastal Waterway. It lies south of Siesta Key and north of Venice, about 15 miles from downtown Sarasota. Two bridges connect Casey Key to the mainland: the historic one-lane Blackburn Point swing bridge from Osprey at the north end and the Albee Road drawbridge from Nokomis at the south end. Most island addresses read Nokomis or Osprey.
How much does it cost to buy a home on Casey Key?
Casey Key is one of the most expensive addresses on Florida's Gulf Coast, though the range is wider than many buyers expect. The most attainable entry points are the small number of condominiums and older cottages near the island's south end by Nokomis Beach. Bayfront homes with docks occupy the middle of the market, while Gulf-front estates and rare Gulf-to-bay parcels command some of the highest prices in the Sarasota region. Because Casey Key inventory is limited and some sales happen off-market, current pricing is best confirmed with a local agent rather than portal estimates.
Do you need flood insurance on Casey Key?
Effectively yes. Virtually all of Casey Key lies within a FEMA special flood hazard area, so lenders require flood insurance on financed purchases, and carrying it is prudent even in cash deals. Casey Key buyers should also budget for windstorm coverage and request the home's elevation certificate early, since elevation relative to base flood elevation drives both insurability and premium. Newer elevated construction on Casey Key generally insures more favorably than older ground-level cottages.
Are there condos on Casey Key?
Very few. Casey Key is almost entirely single-family, with no high-rises anywhere on the island. A small number of low-rise condominium and cottage-style communities cluster near the island's south end around Nokomis Beach, and they represent the lowest-priced way to own on Casey Key. Buyers who want a larger condominium selection typically compare nearby Venice Island, Nokomis, and Siesta Key alongside Casey Key.
What is boating access like from Casey Key?
Boating is one of Casey Key's core advantages. Bayside homes front Little Sarasota Bay and Blackburn Bay along the Gulf Intracoastal Waterway, and many have private docks and lifts. Venice Inlet, at the island's southern tip beside North Jetty Park, provides direct deep-water access to the Gulf of Mexico. Because bayside depths vary, Casey Key buyers should verify controlling depth at a specific dock, their vessel's draft, and the opening schedules of the Blackburn Point swing bridge and the Albee Road drawbridge before closing.
What schools serve Casey Key?
Casey Key is served by Sarasota County Public Schools. Island addresses are commonly zoned for Laurel Nokomis School, a K-8 campus in Nokomis, and Venice High School. Pine View School in nearby Osprey, Sarasota County's application-based gifted magnet, is a short drive from the island's north bridge, and private options operate in Venice and Sarasota. School attendance zones can change, so buyers should confirm current zoning for a specific Casey Key address directly with the district.
Can you build a new home or rebuild on Casey Key?
Yes. Much of Casey Key's newest construction follows the 2024 hurricane season, when Helene and Milton damaged many older ground-level homes on the island. New and substantially improved homes on Casey Key must meet current FEMA elevation standards, and renovation of older homes is limited by the 50% substantial-improvement rule unless the structure is brought into full compliance. Gulf-front projects typically also require state permitting seaward of the Coastal Construction Control Line. Sarasota County land-use rules keep the island low-rise and residential, so new construction on Casey Key means single-family homes, not condo projects.
How is Casey Key different from Siesta Key?
Casey Key and Siesta Key are neighboring Sarasota County barrier islands with distinct characters. Siesta Key has a village of shops and restaurants, extensive condominium stock, steady visitor traffic, and the well-known public Siesta Beach with its quartz-sand shoreline. Casey Key, a few miles south, is almost entirely single-family, has no commercial district and no high-rises, and concentrates its public beach access at the south end at Nokomis Beach and North Jetty Park. Buyers seeking walkable amenities and rental-oriented condos usually compare Siesta Key first; buyers seeking privacy, direct beach frontage, and Gulf-to-bay estates usually look to Casey Key.
