Sullivan's Island Short-Term Rental Rules: What Buyers Should Know

"We find SC Lighthouse's method of ownership, while uncommon in the Town, does not constitute commercial use of the property."

The Post and Courier reported that the line comes from a South Carolina Court of Appeals opinion issued February 18, 2026, in Pacaso, Inc. & 2 SC Lighthouse, LLC v. Town of Sullivan's Island. It reversed a circuit court ruling and, with it, unsettled something almost every buyer on the island assumes is fixed: that Sullivan's Island simply does not allow short-term rentals, full stop, end of conversation.

If you are shopping for a second home here and the rental income is part of the math, the math just got more complicated. Not because the island suddenly allows Airbnbs. It doesn't. But because the rules governing what counts as a rental, who gets to keep operating one, and what happens when you buy a house that currently has one, are less settled than the listing sheet implies.

The ban's history matters

Sullivan's Island has long prohibited short-term rentals. Everyone who's spent five minutes researching the island knows this part. What gets glossed over is how the ordinance affected properties that were already operating as vacation rentals when it passed.

The ruling that reopened the gray zone

The Pacaso case is where this gets more interesting, and more current.

Pacaso is a company that sells fractional ownership shares in homes, typically one-eighth interests, with each co-owner getting scheduled weeks throughout the year and Pacaso handling the logistics. As ABC News 4 reported, a property at 3115 Ion Avenue, held by an entity called 2 SC Lighthouse, LLC, was set up this way. Neighbors objected. A resident named Tim Emrich organized a group called Stop Pacaso, arguing the arrangement functioned exactly like a vacation rental even if the paperwork called it something else. The town's zoning administrator agreed and issued a violation. The Board of Zoning Appeals backed that decision, unanimously, in a meeting Emrich later described to ABC News 4 as two hours of "sort of spirited back and forth."

Pacaso and the property owner appealed. And, as Lucky Dog News reported, the South Carolina Court of Appeals sided with them in a split 2-1 decision in February 2026. The South Carolina Court of Appeals based its reasoning on a distinction that sounds technical but has real teeth: the people staying in the home were owners, not tenants, and without a landlord-tenant relationship or a payment for temporary lodging, the court found the town's own definition of a short-term rental didn't apply. The court also found the Board of Zoning Appeals had overstepped by applying restrictions that weren't in the original violation notice.

Here's what that means in practice. The island's ban on rentals still stands. What no longer stands, at least for now, is the assumption that fractional or co-ownership models automatically fall under that ban. A court has ruled that this arrangement is not, by the plain language of the current ordinance, a commercial rental.

This is not fully settled. As The Real Deal reported in April 2026, Pacaso's litigation with the town is still ongoing, and towns that lose a ruling like this typically respond by rewriting the ordinance rather than accepting the outcome. If you're buying on Sullivan's Island because you value knowing exactly who lives around you, this is a case worth tracking rather than treating as closed.

What the scarcity is actually telling you

Now for the number that gets misread every time someone pulls it up. Short-term rental data for Sullivan's Island covering June 2025 through June 2026 shows revenue per listing up 18 percent and average daily rate up 9.5 percent. Read on its own, that looks like booming demand. It isn't, or at least not primarily.

Over the same period, active listings on the island fell 11.5 percent, down to 46, while occupancy actually dipped slightly. That combination, rising revenue per unit alongside a shrinking pool of units, is a supply story, not a demand story. The island isn't attracting more renters. It may be losing rental properties as owners convert them back to full-time residential use. What's left commands a scarcity premium.

If you're evaluating a property because of its existing rental income, this table is the honest version of that pitch. You are not buying into a growing market. You are looking at a shrinking pool of rental listings.

What this means if you're the one closing

Before you write an offer on anything advertised with existing rental history on Sullivan's Island, get answers to these in writing, not verbally from the listing agent:

1. Is there an active, town-issued vacation rental license tied to this specific address, and what is its status today?
2. If the appeal is fractional or co-ownership structure, has legal counsel reviewed whether the current court ruling actually applies to your intended use, given that the case is still being litigated?
3. Are there separate HOA or covenant restrictions on the property that are stricter than the town's ordinance?

None of this is legal advice, and the Pacaso litigation could look different by the time you're at the closing table. What it should tell you is that "rental potential" on Sullivan's Island is not a fixed feature of the house. It's a status that has to be actively verified.

A few questions worth asking directly

Does the February 2026 ruling mean I can now legally operate a traditional Airbnb on Sullivan's Island? No. The ruling addressed a fractional ownership structure specifically. The town's underlying ban on rentals remains in place for standard vacation rental use.

Is the Pacaso case finished? Not fully. Reporting from April 2026 describes the litigation as ongoing, and the town could still pursue further appeal or revise its ordinance in response.

Sullivan's Island still trades on being the quiet island, the one without hotels or chain restaurants or a rotating cast of weekend renters next door. That reputation is intact. What's changed is that the legal architecture holding it in place has a live crack in it, and if rental income or neighborhood character is part of why you're buying here, that crack is worth understanding before you sign anything, not after.
