A brief history
The island gets its name from a 1918 real estate stunt: developer Bill McAdoo buried wooden chests and announced a treasure discovery near the first hotel (built 1915 by Whitey Harrell, who called it "Coney Island") to attract investors. The scheme worked well enough to brand the place permanently. The towns of Sunset Beach, Boca Ciega, Treasure Island, and Sunshine Beach were incorporated by Special Act of the Florida Legislature on May 3, 1955. Most of the current housing stock went up in the postwar boom years of the 1950s through 1970s, when modest CBS ranch homes filled the interior streets and cottages lined the Gulf-side blocks.
The housing mix
Concrete block ranch homes from the 1950s–70s are the most common type on interior streets — typically 3 bedrooms, 2 baths, and 1,400–1,800 square feet, priced $450K–$750K. Canal-front homes with private dockage start around $800K and climb past $2M for direct Gulf access. Gulf-front condos in low-rise buildings along Gulf Boulevard run $500K–$1.5M. Post-Hurricane Idalia rebuilds (elevated, newer construction) are increasingly visible and price above $1.2M. Nearly all structures on the island are in FEMA Zone AE or VE, so flood insurance is a non-negotiable line item — budget $1,500–$5,000+ per year depending on the elevation certificate.
Who lives here
Retirees and second-home buyers are the dominant buyer profile, drawn by beach access and the slower pace of a small-city island. Full-time families make up a smaller segment, with children often enrolled in the Pinellas County Schools choice/magnet system rather than the zoned Azalea schools. Remote workers appear in the buyer mix, particularly for canal-front homes where a dock doubles as office scenery. Most buyers arrive from elsewhere in the Tampa Bay metro or relocate from Northern states seeking year-round Gulf access without committing to a larger-city footprint.

Frequently asked about Treasure Island
Where does the name "Treasure Island" come from?
The name traces to a deliberate 1918 marketing hoax. Real estate developer Bill McAdoo buried wooden chests and announced that treasure had been unearthed near Whitey Harrell's beachfront hotel — then the only structure on the island. The publicity stunt attracted investors and the name stuck. The area was formally incorporated as the City of Treasure Island by Special Act of the Florida Legislature on May 3, 1955.
What flood zone is Treasure Island in?
Nearly the entire island is in a FEMA Special Flood Hazard Area. Gulf-front properties are typically in Zone VE (coastal high hazard with wave action), requiring the highest flood insurance premiums — often $1,500–$5,000+ per year. Interior and canal-front properties generally fall in Zone AE (high hazard, no wave action). Flood insurance is mandatory for any property with a federally backed mortgage. Post-Hurricane Idalia (2023), properties meeting the substantial damage threshold (repair cost ≥ 49% of structure value) must be elevated to current flood standards before repair. Always pull the specific elevation certificate before making an offer.
What schools serve Treasure Island?
Treasure Island falls under Pinellas County Schools. The zoned schools are Azalea Elementary (PreK–5), Azalea Middle School (6–8), and Boca Ciega High School (9–12), which offers an IB program. Pinellas County's open choice and magnet system lets families apply for placements at higher-rated schools across the district. Many Treasure Island families participate in the choice lottery, particularly at the elementary level. Confirm current school boundaries with Pinellas County Schools before writing an offer.
How does Treasure Island compare to Madeira Beach and St. Pete Beach?
Madeira Beach — directly to the north across John's Pass — has a denser tourist commercial strip and draws more day-trippers to the boardwalk. St. Pete Beach, to the south, has a larger resort presence and higher concentration of vacation rentals. Treasure Island sits in the middle: less commercial than Madeira Beach, less resort-oriented than St. Pete Beach. Full-time residents favor it for the quieter downtown and the residential-first land use. Condo investors often prefer St. Pete Beach for rental yield; homeowners often prefer Treasure Island for neighborhood feel.
What is the current market like for Treasure Island homes?
As of April 2026, the median listing price in Treasure Island is approximately $700,000, down roughly 11% from a year prior. Homes are averaging around 97 days on market — elevated compared to the broader Tampa Bay metro. Rising flood insurance costs and post-Idalia insurance availability challenges are the primary headwinds. Canal-front and Gulf-front properties are taking longer to sell than inland ranches. If you're budgeting for a Treasure Island purchase, add flood insurance ($1,500–$5,000+/year) and windstorm insurance to your carrying-cost model.
