Ask what a short-term rental license is actually worth on Isle of Palms, and the honest answer is: not much on its own. It's paperwork. Ask the same question a few hundred yards away on Sullivan's Island, across Breach Inlet, and the answer flips entirely. The Post and Courier reports that short-term rentals are prohibited on Sullivan's Island.
Same barrier island chain. Same marsh grass and pluff mud. Two completely different assets.
That difference matters more than most listing sheets let on, especially for anyone comparing Isle of Palms to its neighbors while shopping for a home with rental flexibility. The instinct is to treat "can I rent this house short-term" as a yes-or-no zoning question. The real question, once you look at how these four towns actually govern rentals, is whether the license itself carries value independent of the house, or whether it's simply a formality that comes with the address.
The Referendum That Left Isle of Palms Uncapped
In November 2023, Isle of Palms voters decided a question that still shapes the market today: whether to cap investment short-term rental licenses at 1,600, as The Post and Courier reported. The referendum came after a resident petition and a 5-4 city council vote that sent the issue to the ballot rather than adopting it outright. When the votes were counted, the cap failed, opposed by 54.5 percent of voters.
That single result is why Isle of Palms remains, structurally, an outlier among its neighbors. There is no ceiling on how many short-term rental licenses the city will issue. The license isn't scarce.
Debate over protecting quieter residential pockets of the island has continued.
What "No Cap" Actually Buys You at Closing
Here's where the practical friction shows up. A buyer who has shopped Folly Beach or Mount Pleasant, where licenses are capped, sometimes assumes every Charleston-area beach town works the same way, and treats an existing rental license as something the seller is handing over as part of the deal.
The island's own numbers back this up. In the city's most recent short-term rental license analysis for the 2025-2026 license year, roughly 682 of the island's 3,129 single-family dwelling units carried a rental license, close to 22 percent. Condominiums run higher, since much of that inventory in Wild Dunes and the former hotel-adjacent buildings along the beachfront was built with rental use in mind from the start. The point isn't the exact percentage. It's that even with zero cap and no scarcity pressure, most single-family owners on the island still aren't renting short-term. Plenty of buyers are choosing a full-time or seasonal residence, not an investment vehicle, which should temper any assumption that every house for sale here is priced with rental income baked in.
What a buyer actually needs to check on Isle of Palms isn't whether a license exists. It's whether the specific address can support one under the city's occupancy formula (tied to bedroom count and available parking), whether the neighborhood's HOA or regime document layers on stricter rules than the city allows, and whether the property has a clean compliance history. The city's 2025 ordinance update changed how many founded complaints trigger a license revocation hearing and clarified that garbage-related complaints don't count toward that total, a small but real detail for anyone buying a property with an active rental history.
Three Doors Down, Three Different Rulebooks
Move off Isle of Palms and the entire framework changes.
Community | Short-term rental policy | What it means for a buyer |
|---|---|---|
Isle of Palms | No cap on licenses since a 2023 referendum to limit them failed | License is a compliance step |
Sullivan's Island | Short-term rentals prohibited | Rental use is essentially off the table |
Mount Pleasant | Capped at 400 permits | Check the local rental rules before making an offer |
Folly Beach | Cap-based system, reworked in September 2026 when city council repealed and reinstated the ordinance with a new flat fee replacing the old income-based fee structure | The cap remains the gating factor, but the cost of holding a license just changed, which is worth confirming before underwriting any rental income |
Sullivan's Island took the most restrictive path of any of these markets, banning short-term rentals outright rather than capping them. Mount Pleasant chose a fixed number, 400, and closed the door once that number filled.
Folly Beach offers the freshest example of how quickly these rules can move. According to The Post and Courier, on September 8, 2026, the city council took the unusual step of repealing its own rental cap ordinance and reinstating it in the same session, this time dropping the income-based fee that had layered on top of the standard business license fee. The city had collected more than $1.5 million in registration fee revenue in 2025 under the old structure, so this wasn't a minor housekeeping change. One council member argued publicly that the island needs rental reform without needing a cap at all, a debate that isn't fully settled even after the vote.
None of this makes one town better than another. It means the four markets aren't interchangeable the way a quick scroll through listings might suggest, and the difference shows up specifically in how a rental-minded buyer should approach due diligence in each one.
The Question Worth Asking Before You Write an Offer
On Isle of Palms, the useful question isn't "does this house have a rental license." It's "what do city rules allow at this specific address, and does the HOA or regime document allow it."
On Mount Pleasant or Folly Beach, the question flips: does an existing license convey with the sale, is it in good standing, and what would it cost to replace if it didn't transfer, given that new licenses may not be available at all. On Sullivan's Island, the honest question is whether short-term rental use is even part of the plan, since it almost certainly isn't an option outside the rare grandfathered address.
Disclosure paperwork can be a starting point, but it won't tell a buyer whether a permit is scarce or a formality. That distinction only becomes clear once you know which town you're standing in.
A Few Straight Answers
What should a buyer check about a short-term rental license on Isle of Palms? Check the city's current licensing requirements for the specific property.
If I buy a house on Mount Pleasant or Folly Beach hoping to rent it short-term, can I count on getting a license? Not automatically. Mount Pleasant has a 400-permit cap, and Folly Beach operates under its own cap structure that was just reworked in September 2026. In both cases, whether an existing license conveys with the specific property is something to confirm in writing before making an offer.
Is there any way to rent short-term on Sullivan's Island? Short-term rentals are prohibited on Sullivan's Island.
Do HOA or regime rules matter even where the city allows short-term rentals? Yes, and this is one of the most commonly missed details. A property can meet every city requirement on Isle of Palms and still be restricted by a stricter HOA or regime document. Always review the governing documents alongside the municipal rules.
Rental rules on these islands are set locally and can shift with a single council vote, so treat every figure here as a starting point for your own verification, not a substitute for it.
