Treasure Island vs St. Pete Beach for Retirement: Costs, Housing & Lifestyle Compared
Treasure Island and St. Pete Beach are adjoining Pinellas County barrier-island cities, and both are genuinely age-concentrated retirement markets still working through real, still-unfolding recovery from Hurricanes Helene and Milton in 2024. Treasure Island is the smaller of the two, roughly 6,584 residents with an estimated 40.6% age 65-plus, cultivating a quieter, more residential, retro-styled character than some neighboring beach towns, with roughly 2,000 homes and businesses damaged by the back-to-back 2024 storms. St. Pete Beach is a larger, more historically prominent city of roughly 8,879 residents with a median age of 60.4 and 38.5% age 65-plus, anchored by the landmark "Pink Palace" Don CeSar Hotel and the National Register-listed Pass-a-Grille Historic District, whose flagship hotel closed for roughly six months after the 2024 storms and whose $125-126 million beach renourishment project was still finishing as recently as early 2026. Choosing between them largely comes down to whether a retiree wants Treasure Island’s quieter, smaller-scale residential feel, or St. Pete Beach’s deeper historic identity and marina culture at Pass-a-Grille. Both cities also illustrate the same structural reality facing every Pinellas County barrier island: near-universal FEMA high-risk flood-zone exposure, elevated windstorm and flood insurance costs, and real post-Surfside condo-safety inspection and reserve-funding pressure on older buildings. Neither city has a hospital or a dedicated 55-plus community within its own limits, so residents of both rely on mainland St. Petersburg facilities for full-service healthcare and on St. Petersburg-area developments for age-restricted housing options. The core difference between them is scale and identity rather than fundamentals: Treasure Island trades on being the quieter, more residential alternative, while St. Pete Beach trades on genuine national name recognition and historic depth.
| Dimension | Treasure Island | St. Pete Beach |
|---|---|---|
| Population | Roughly 6,584 (2020) | Roughly 8,879 (2020) |
| Median age | Not separately reported, though the 65-plus share suggests a comparably older population to St. Pete Beach | Roughly 60.4 years |
| 65+ population share | Roughly 40.6%, one of the more age-concentrated populations among Tampa Bay’s beach communities | Roughly 38.5% |
| Community character | A quieter, more residential, retro-styled barrier island, less heavily commercialized than some neighboring beach towns, particularly in the Sunset Beach neighborhood | A historically prominent, nationally recognized beach city anchored by the landmark Don CeSar Hotel and the Pass-a-Grille Historic District |
| Historic district status | No National Register historic district identified in this research | The Pass-a-Grille Historic District, listed on the National Register of Historic Places in 1989, with roots as a fishing/resort settlement since the 1880s-1900s |
| Signature landmark | No single nationally recognized landmark identified; the island’s identity centers on its beach and retro coastal character broadly | The Don CeSar Hotel ("Pink Palace"), opened 1928, closed roughly six months after the 2024 storms and did not resume reservations until April 2025 |
| 2024 hurricane damage | Hurricanes Helene and Milton together damaged roughly 2,000 homes and businesses on the island | Nearly 5 feet of storm surge from Helene alone; the city collected roughly 2.1 million cubic yards of storm debris, described as the largest volume ever collected there |
| Recovery status as of 2026 | Recovery work continuing across the island, including the landmark Thunderbird Beach Resort’s full reconstruction as a planned four-story property | A $125-126 million, roughly 2.5-million-cubic-yard county beach renourishment project was still finishing as recently as early 2026 |
| Median home sale price | Not separately reported in this research; condo and single-family pricing varies widely by building age and Gulf-front proximity | Roughly $605,000 (2026), down about 5.5% year-over-year, with homes taking a median 83 days to sell versus 45 a year earlier |
| Flood insurance exposure | Almost entirely within mapped FEMA flood zones as a low-lying barrier island; buyers should assume meaningful flood risk on essentially any address | Virtually every parcel falls into FEMA high-risk AE or VE zones; waterfront properties reportedly run $5,000-$9,000/year, with VE-zone structures potentially exceeding $10,000-$12,000/year |
| Hospital access | None on the island; residents rely on facilities in St. Petersburg and greater Pinellas County a short drive across the causeway | None on the island; residents rely on HCA Florida Pasadena Hospital, St. Anthony’s Hospital, and the Bay Pines VA Medical Center across the bridge |
| Walkability | Genuinely walkable along its compact Gulf Boulevard commercial strip and beachfront, with a citywide park system designed so every neighborhood sits within walking distance of a park | Walk Score rates the city 80/100 ("Very Walkable"), lower than downtown St. Petersburg, reflecting a more spread-out Gulf Boulevard outside the compact, genuinely walkable Pass-a-Grille core |
| Boating/marina culture | John’s Pass, at the island’s northern tip, connects the Intracoastal Waterway to the open Gulf, supporting recreational boating and a longstanding charter-fishing fleet | Pass-A-Grille Marina, established 1966, provides access to Shell Key, Egmont Key, and Boca Ciega Bay, anchoring a genuine working marina culture |
| Beach-ranking recognition | No specific national beach-ranking identified in this research | Tripadvisor’s #1 U.S. beach in 2021, though by 2026 rankings, neighboring Clearwater Beach held that spot and St. Pete Beach ranked around #7 among Florida beaches per USA Today |
| 55-plus community options | No dedicated age-restricted community identified within city limits; the area’s retiree population is broadly distributed rather than concentrated in a single development | None within city limits; the area’s 55-plus communities (Terrace Park of 5 Towns, Boca Ciega Point, Village Green) sit in St. Petersburg proper, a short drive away |
| Municipal footprint | Roughly 5.3 square miles, most of it water, limiting the range of in-town amenities compared with larger Pinellas cities | Occupies most of Long Key, a larger barrier island footprint incorporating several formerly separate communities including Pass-a-Grille |
| Airport access | St. Pete-Clearwater International Airport (PIE) roughly 12 miles / 25 minutes; Tampa International (TPA) roughly 25 miles / 40 minutes | St. Pete-Clearwater International Airport (PIE) roughly 21 miles / 35 minutes |
| Property tax structure | A municipal millage layered on top of Pinellas County’s countywide rate and school/special-district levies | City millage set at 3.0913 mills for 2025/2026, plus Pinellas County general fund and school board millage layered on top |
| Condo/HOA fee pressure | Post-hurricane special assessments are a genuine, statewide-documented consideration for Florida condo owners under post-Surfside SIRS rules | Older condo stock (much built 1960s-1980s) squarely subject to Milestone Inspection and Structural Integrity Reserve Study mandates, with regional HOA fee growth reported at 17.2% year-over-year |
| Homestead exemption and Save Our Homes cap | The standard Florida homestead exemption ($51,411 for 2026) and Save Our Homes 3%/CPI cap apply to primary residents | The same statewide homestead exemption and Save Our Homes cap apply to primary residents |
| Distance between the two cities | Directly adjacent to St. Pete Beach, immediately north | Directly adjacent to Treasure Island, immediately south |
| Housing product range | Single-family Gulf-front and canal-front homes, condo/apartment buildings, and beachfront resort/rental properties | Gulf-front and bay-front condominiums and mid-rise buildings, canal-front single-family homes, and historic cottages and bungalows in Pass-a-Grille |
| New construction activity | Meaningfully active in the wake of 2024 hurricane damage, including the Thunderbird Beach Resort’s full reconstruction as a four-story property | Limited given the island’s built-out, historic character; most activity is renovation or storm-recovery rebuild rather than new greenfield construction |
| Golf availability | Not a defining feature; golf options are available on the nearby Pinellas County mainland | No golf course within city limits; the nearest notable club, Isla Del Sol Yacht & Country Club, is across the water in St. Petersburg |
| Arts and culture | Centers on beach and retro coastal character rather than a defined arts district; residents look toward St. Petersburg for deeper cultural offerings | On-island offerings limited mainly to Pass-a-Grille’s historic architecture and small galleries; major institutions like the Dalí Museum sit across the bridge |
| Origin and incorporation | Modern character dates to the post-World War II boom; formally incorporated in 1955 | Incorporated 1957 through consolidation of several separate communities, including the much older Pass-a-Grille settlement dating to the 1880s-1900s |
| Traffic/evacuation routes | Seasonally heavy traffic along Gulf Boulevard and across causeway connections, particularly during peak winter and spring tourist months | Corey Causeway and Pinellas Bayway serve as primary evacuation routes and a real chokepoint during storm evacuations or peak-season traffic |
| Overall summary | The right choice for retirees who want a quieter, smaller-scale, more residential barrier-island community | The right choice for retirees who want genuine historic depth and national name recognition, provided they accept a still-incomplete recovery timeline |
| Best overall fit | Retirees who prioritize a laid-back, less commercialized beach-town feel over deeper historic prestige | Retirees who prioritize the Pass-a-Grille historic district and the Don CeSar’s national name recognition |

Treasure Island
A small, retro-styled Gulf-front barrier island city in Pinellas County with a genuinely age-concentrated population and a laid-back, residential feel distinct from busier neighboring beach towns — but one still visibly rebuilding from the direct hits it took from Hurricanes Helene and Milton in 2024.
St. Pete Beach
An incorporated Gulf-front barrier-island city formed by the 1957 merger of several small beach communities, home to the historic "Pink Palace" Don CeSar Hotel and the Pass-a-Grille Historic District — still working through a genuine, multi-year recovery from Hurricanes Helene and Milton (2024), not a fully closed chapter as of 2026.
