Isle of Palms,
Treasure Island Homes for Sale

Isle of Palms is a single-family waterfront island in Treasure Island (ZIP 33706), set on the Boca Ciega Bay and intracoastal side of the barrier-island city. It is one of the dredged-fill residential islands built out through the 1950s for direct water access, so most homes sit on a canal or open-bay lot with a seawall and a private dock rather than on a dense interior grid.

The appeal here is boating and water, not a master-planned amenity package. Many homes carry a dock with a boat lift and quick, deep-water access out toward John's Pass and the Gulf of Mexico, and the streets are quiet and residential rather than commercial. Homes range widely in size and vintage, from original mid-century ranches to rebuilt and elevated newer construction, so condition and elevation vary meaningfully from one property to the next.

Crucially for a buyer, the City of Treasure Island zones Isle of Palms primarily RU-75, which presumes a property is a tourist dwelling only if it sees more than two changes of occupancy in a 12-month period. In practice that makes the island an owner-occupied and long-term or seasonal market rather than a weekly vacation-rental block, which is the opposite of the rental-driven condo corridors elsewhere on the beaches. Confirm the zoning and any rental rules for the exact address before you assume use.

The honest read is that the water and the structure do the work. On a Gulf-side barrier island you are buying a flood-zone home, so the seawall age and condition, the finished-floor elevation, the dock and lift, and any post-storm repair history matter as much as the floor plan. Two similar-looking homes can carry very different true costs once you price the insurance, the elevation, and the waterfront infrastructure.
