Treasure Island at a glance
Local notes: Treasure Island
A barrier-island beach town between St. Pete Beach and John's Pass, with canal-front homes, low-rise condos and vacation rentals.
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.
Condos are a big part of the Treasure Island market. Florida's post-Surfside condo safety laws require milestone structural inspections and fully funded structural reserves for many buildings. Review the association's reserve study, milestone reports and any special assessments before you buy or list.
