On August 14, 2026, a Ninth Judicial Circuit judge looked at Folly Beach's three-year-old short-term rental cap and the fee that funded it and called the fee "an improper tax disguised as a fee." With that, the 800-license cap that had governed who could legally rent an investment property on the island collapsed, at least for now. The city says it plans to appeal and is weighing a moratorium on new licenses while a separate rental study continues.
If you are shopping for a beach house anywhere on this coast right now, that ruling should catch your attention even if you have no interest in Folly Beach. It is the clearest possible proof of something buyers routinely miss when they compare listings: the price on the sign tells you what the house costs. It tells you almost nothing about what you are allowed to do with it once you own it. That answer lives in a rulebook that sits underneath the listing, and on this stretch of coastline, the rulebook changes every few miles, and sometimes every few months.
Why a Ruling in Folly Beach Matters on Islands That Have Nothing to Do With Folly Beach
Folly Beach's saga is worth walking through once because it shows how unstable these rules can be even after they look settled. Voters approved the 800-license cap on investor-owned rentals by a 78-vote margin in a 2023 referendum, when the island already had 1,125 rental properties on the books, or 43 percent of its housing stock. The cap survived one legal challenge in February 2026, when the South Carolina Court of Appeals ruled it was a business regulation rather than a zoning change. It did not survive a second, different challenge over how the cap was funded, which is the one that succeeded in August.
None of that happened because Folly Beach residents changed their minds. It happened because two separate lawsuits attacked the ordinance from two separate angles, years apart, and the second one worked. A cap can look permanent for three years and then not be permanent at all. That is the mechanism worth understanding before you assume any single island's current rule will still be the rule by the time you close.
Five Islands, Five Rulebooks
Zoom out from Folly and the pattern gets even more visible. Charleston's barrier islands do not share one short-term rental policy. Each town wrote its own, on its own timeline, often after its own referendum fight.
| Location | Current rental posture | What a buyer needs to know |
|---|---|---|
| Sullivan's Island | Rentals under 30 days banned since 2002 | Only a small number of grandfathered pre-2002 properties may still rent short-term, and that status does not transfer to a new owner |
| Isle of Palms | No cap on investor licenses | Voters rejected a 1,600-license cap in November 2023, with 54 percent opposed, but the petition that forced that vote came from more than 30 percent of registered voters, so the question can resurface |
| Kiawah Island | Capped in designated zones, administered through the town and the Kiawah Island Community Association | As of December 31, 2025, only 88 licenses, or 17 percent, remained available in the capped areas, out of more than 1,300 issued |
| Seabrook Island | Restricted through a designated Short-Term Rental Overlay District | The town formally mapped the overlay district in 2024, layering zoning on top of licensing |
| Folly Beach | Cap struck down August 14, 2026, appeal and possible moratorium pending | The rule that governed the island for three years is currently in legal limbo |
Five islands within roughly a 45-minute drive of each other, and five different answers to the question "can I rent this out." That is not a footnote. It is the variable that determines whether a purchase functions as an income property, a personal retreat with occasional rental income, or a personal retreat with no rental income at all.
The Ban That Makes Sullivan's Island the Most Expensive Address in the Region
Sullivan's Island closed the door on short-term rentals entirely back in 2002, and that single fact does a lot of work in explaining its price. For full-year 2025, the Charleston Trident Association of Realtors put the island's median sale price at $4.2 million, the highest in the region, even though sales volume fell 20.5 percent and the median itself dropped 15.7 percent from the year before. Move the window to the first five months of 2026 compared with the same period in 2025, and the median jumps to $4.75 million, up 21.8 percent. Both numbers are accurate. They just describe different stretches of a market where sales are thin enough that a handful of transactions can swing the median hard in either direction.
What holds steady across both windows is who is buying. When a rental income strategy is off the table by law, the only buyers left are people who want the house for themselves, and that pool skews toward buyers who do not need the property to pay for itself. Scarcity of use, not scarcity of land, is doing a good part of the pricing work here.
Isle of Palms Bet Against a Cap. The Bet Isn't Settled.
Isle of Palms sits a few miles away with the opposite policy. No cap exists on investor rental licenses, and voters confirmed that stance decisively in 2023. The market has responded the way you would expect a rental-friendly, cap-free coastal market to respond. CTAR data put IOP's full-year 2025 median sale price at $2.66 million, up 32.5 percent year over year, on 132 closed sales. Looking at January through May 2026 against the same months a year earlier shows a smaller but still meaningful gain, with the median at $2.195 million, up 8.4 percent, alongside a 32.4 percent jump in transaction volume.
That freedom is not unconditional everywhere on the island, though. Wild Dunes, the gated resort community on IOP's northern tip, runs its own economics on top of the city's rules. Owners there pay a 2026 annual community assessment of $983 per dwelling, plus an additional $100 rental access fee specifically for using the home as a short-term rental. A real estate transfer fee applies at purchase too, currently 1 percent of the sale price, rising to 1.25 percent starting September 1, 2026. None of that requires a license lottery. It is simply the private toll for renting inside a community that layers its own charges on top of a city policy that otherwise has no cap at all.
And the no-cap stance itself is not guaranteed to last. The 2023 petition that forced a referendum came from more than 1,100 residents, over 30 percent of registered voters, organized around exactly this issue. A buyer underwriting a purchase on the assumption that IOP will always be the easy island is underwriting against a policy that has already been challenged once and lost by a margin narrow enough to matter.
Kiawah's Math Runs Through a Gate, Not a Zoning Map
Kiawah Island layers two separate gatekeepers on top of each other. The town issues short-term rental business licenses, and it caps the total number available in designated areas. As of the end of 2025, only 88 of those licenses, 17 percent of the total pool, remained available. Separately, the Kiawah Island Community Association administers eligibility by security gate, with rentability generally tied to whether a property sits between the island's first and second gates, and KICA maintains its own cap on active licenses for single-family homes on top of that. A property can be geographically eligible and still be stuck behind a licensing waitlist, or licensed and still fall inside a community that restricts rentals regardless of zone.
That scarcity sits underneath a median list price for single-family homes running between $1.8 million and $2.1 million as of spring 2026, with oceanfront estates reaching into the $5 million to $15 million range. Seabrook Island, next door, took a different route entirely, formally mapping a Short-Term Rental Overlay District in 2024 rather than relying on a simple numeric cap, and it has built a reputation as the quieter, more residential option of the two, with average home values surpassing $1 million as of spring 2026.
What to Verify Before You Write an Offer
The pattern across all five markets points to the same practical lesson: rental eligibility is a due diligence item, not an assumption you can read off a listing description. Before you write an offer on a coastal property with any rental income built into your plan, confirm:
- Whether the specific parcel currently holds an active rental license, and whether that license is transferable to a new owner or dies with the sale
- Whether the license sits in a capped zone with a waitlist, and how long that waitlist currently runs
- Whether a private HOA, resort association, or community overlay layers its own fees or restrictions on top of the town's rule
- Whether the town's current policy has been the subject of a recent referendum, petition, or lawsuit, since that history is often the best predictor of whether the rule is stable or contested
- Whether the appeal or moratorium period, where one exists, could affect your ability to obtain a license after closing rather than before
A Few Direct Questions Worth Answering
If I buy in Folly Beach right now, can I count on getting a rental license? Not with certainty. The cap that governed licensing for three years was struck down in August 2026, the city has said it intends to appeal, and a moratorium on new licenses is under consideration. Anyone counting on rental income there this year is buying into an open legal question, not a settled rule.
Does a "no cap" policy mean the rule will never change? No. Isle of Palms has no cap today, but that policy survived a referendum by a margin of 54 percent, forced onto the ballot by a petition that over 30 percent of registered voters signed. A policy with no cap can still be a policy under active pressure.
Are Kiawah and Seabrook interchangeable for rental purposes? Not really. Kiawah runs a gate-zone system with a numeric license cap that is nearly full in its restricted areas, while Seabrook relies on a mapped overlay district that tends to limit short-term rental activity more broadly. The mechanics, and the odds of getting a license at all, differ meaningfully between the two.
Regulatory frameworks like these shift on their own timelines, driven by referenda, lawsuits, and council votes that have nothing to do with any single closing date. A price that looks like a bargain next to its neighbor is sometimes a bargain precisely because it cannot generate the income the listing photos imply. If you are weighing a barrier island purchase and want someone who tracks these rules island by island, not just island by price, King & Society can walk you through what a specific parcel is actually allowed to do before you make an offer on it.
