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.
Housing stock in Treasure Island
Treasure Island has about 6,192 housing units. 44% are single-family homes and 34% are in buildings with 10 or more units, and 1% are mobile or manufactured homes. 75% of homes were built before 1980 and 6% were built in 2000 or later. The median resident is 62.7 years old. About 29% of all housing units are held for seasonal, recreational or occasional use, one of the highest shares in Pinellas. Expect second-home owners, snowbirds and vacation-rental investors in the buyer pool.
With 75% of homes built before 1980, insurer questions about roofs, wiring (including older panels) and galvanized or cast-iron plumbing are routine.
What drives insurance prices in Treasure Island
- Home age. The median build year here is 1970. That predates the 2002 Florida Building Code, so expect underwriters to ask about roof age, wiring and plumbing.
- Roof age and shape. This is often the single biggest factor in Florida. Hip roofs and newer roofs rate better.
- Wind mitigation features. Roof straps, impact openings and secondary water barriers earn credits that insurers must offer by Florida law.
- Flood. Standard homeowners policies exclude flood. Coastal and low-lying parts of Treasure Island make a separate flood quote essential.

Frequently asked questions
Does homeowners insurance cover flooding in Florida?
No. Flood is a separate policy, through the NFIP or a private flood carrier.
Will I need a 4-point inspection in Treasure Island?
Likely, for older homes. The median home here was built in 1970, and many carriers require a 4-point once a home is roughly 25–40 years old, depending on the carrier.
How does the 50% rule affect homes in Treasure Island?
If a home's damage or planned improvements reach 50% of the structure's market value, NFIP rules generally require it to meet current flood elevation standards. That can mean elevating or rebuilding. Ask the local building department for any substantial-damage determination on the property.
