Life on Casey Key
Casey Key is a barrier island off Nokomis in southern Sarasota County. It's home to Nokomis Beach, Sarasota County's oldest public beach. The historic Blackburn Point Bridge, a swing bridge built in 1925–26 and listed on the National Register of Historic Places, connects the island's north end to the mainland. See our Nokomis and Venice guides for the nearby mainland.
Home Types and Prices
Casey Key homes are primarily residential waterfront properties, and prices vary widely.
Redfin and Realtor.com don't publish Casey Key–only market pages. For ZIP code 34275, which includes Casey Key and much of mainland Nokomis, Redfin reported a median sale price of $494,855 in September 2026 (up 4.4% year over year), with 258 homes sold. That ZIP median is driven mostly by mainland sales and doesn't reflect island prices, which are typically far higher. Ask us for Casey Key–specific comps.
