A barrier-island beach town between St. Pete Beach and John's Pass, with canal-front homes, low-rise condos and vacation rentals.
Treasure Island is home to about 6,553 residents in Pinellas County. The median home value is $621,600, 67% above the typical Pinellas community, and half of homes were built in 1970 or earlier. About 74% of occupied homes are owner-occupied.
Hurricane Helene's 2024 storm surge flooded many homes on Pinellas barrier islands. Under the National Flood Insurance Program's substantial-damage rule (the "50% rule"), a heavily damaged or heavily renovated older home may have to be elevated or brought up to current flood code. That affects price, insurability and renovation plans, so ask for permits, damage determinations and an elevation certificate.
