Drive down I'On Avenue on Sullivan's Island and you'll still see them: hand-lettered yard signs reading "Stop Timeshares on Sullivan's." A resident named Tim Emrich and his wife put up the first ones back in 2022, after a company called Pacaso started selling shares in a home a few doors down. Two hundred signs later, the town's Board of Zoning Appeals ruled against Pacaso seven to nothing. Case closed, or so it seemed.
It wasn't. In February 2026, the South Carolina Court of Appeals reversed that decision, and the reversal turned on a distinction that matters more to Sullivan's Island buyers than almost anything else happening in the market right now.
The ban was never about turnover. It was about the word "rental."
Sullivan's Island has prohibited short-term vacation rentals since 2001. That ordinance is a big part of why the island feels the way it does: no rotating renters, no weekend party houses, a town that reads as year-round residents and longtime second-home families rather than a vacation circuit. It's also part of the pitch for paying island prices. If you're comparing Sullivan's to Isle of Palms, where short-term rentals are licensed and common, the absence of rental turnover here is often the whole point.
The Pacaso case tested what that ban actually covers. SC Lighthouse, LLC bought the I'On Avenue property and split ownership into shares, up to eight owners per home, each holding a fractional interest through the LLC rather than a lease or a nightly booking. Owners pay Pacaso a $99 monthly fee for a scheduling app called SmartStay that coordinates who stays when. Stays run one to two weeks. Nobody pays to occupy the property they already own a piece of.
The town's zoning administrator, Charles Drayton, decided in 2022 that this was a vacation rental in substance, whatever it was called on paper. The Board of Zoning Appeals agreed. So did the circuit court in 2023. Then, in a 2-1 opinion written by Chief Appellate Judge H. Bruce Williams, the Court of Appeals disagreed with all three:
"We find SC Lighthouse's method of ownership, while uncommon in the Town, does not constitute commercial use of the property. Only the owners and their guests ever use the property, and the owners do not pay to stay at their own property."
That's the mechanism. A short-term rental requires a landlord-tenant relationship and a payment for temporary lodging. Fractional ownership has neither. The court wasn't ruling that Pacaso is good or bad for the island. It was ruling that the town's ordinance, as written twenty-five years ago, never anticipated a structure where the "renters" are actually deeded co-owners.
Why this isn't a one-off
If this were a single house on I'On Avenue, it would be a curiosity, not a market fact worth building a decision around. It isn't a single house. According to the Charleston Trident Association of Realtors, there were 29 active fractional-ownership listings on the Charleston Trident MLS as of March 5, 2026, spread across the barrier islands, with Sullivan's Island among them.
Fractional ownership itself isn't new to this coastline. It's been part of Isle of Palms and Wild Dunes for two decades. What's new is a court decision confirming that this specific structure survives an outright rental ban, on an island where that ban is the strictest in the Charleston area. That's a green light other sellers and platforms can read just as clearly as Pacaso did.
For a buyer, the practical question isn't whether the house next door is technically violating an ordinance. It's whether "no short-term rentals" still means what you think it means when you're comparing it against Isle of Palms's licensed and metered rental market or Mount Pleasant's more conventional single-family turnover. On paper, Sullivan's Island still has zero rentals. In practice, a property can now be owned by up to eight unrelated households, professionally managed, with a new occupant arriving every one to two weeks, and the ordinance has nothing to say about it.
What to actually check before you write an offer
The fix here isn't legal advice. It's due diligence that takes an afternoon.
- Ask your agent whether the property, or any property within view of it, is held in fractional or co-ownership through an LLC. This shows up in title work and in how the listing is marketed, not in the square footage sheet.
- Ask whether a property is professionally managed through a platform like Pacaso, since that management fee and scheduling structure is exactly what the court examined.
- Don't treat "no rentals allowed" language in a listing as confirmation that occupancy will be stable. It confirms the town's ordinance category, not the ownership structure.
- If you're weighing Sullivan's Island specifically because the no-rental rule is central to your decision, ask how many fractional-ownership properties currently exist on the street or in the immediate area, not just the island-wide count.
None of this makes fractional ownership disqualifying. Plenty of buyers on other islands have used it successfully for years. It just means the old assumption, that an outright STR ban guarantees uniform occupancy, no longer holds cleanly on Sullivan's Island the way it used to.
The ruling didn't end the fight
This is worth sitting with before you treat the court's decision as the final word. The vote was 2-1, not unanimous. It's an unpublished opinion, which in South Carolina means it isn't binding precedent for future cases, even similar ones. Town Administrator Joe Henderson declined to comment on the outcome when the ruling came down, citing ongoing litigation, and the town had the option to petition for a rehearing or push the case further. Emrich, for his part, said the fight belonged in front of the South Carolina Supreme Court. As of this writing, it isn't clear whether the town pursued that path, and the broader question of how the ordinance should treat co-ownership models remains unsettled at the state level.
That uncertainty cuts both ways for a buyer. It means the current legal landscape could shift again, either toward more fractional ownership if the ruling stands unchallenged, or back toward a tighter ban if the town amends its ordinance to explicitly address co-ownership, which several observers following the case have suggested is the more durable fix compared to relying on a court's interpretation of decades-old language.
The thesis, plainly
Sullivan's Island's rental ban is still real. What it protects against has narrowed. The ordinance stops a landlord from renting a house by the week. It does not, as of this ruling, stop eight owners from splitting a deed and rotating through the same house on a schedule that looks, to the neighbors, almost identical. If you're paying a premium for Sullivan's Island specifically because you believe the island guarantees a stable, single-family-occupied street, that guarantee is narrower today than it was in January 2026, and the market has already noticed with 29 listings built on that narrower reading.
FAQ
Is fractional ownership the same as a timeshare? Legally, no, and that distinction is exactly what the court relied on. A timeshare typically involves a right to use a property for a set period without full ownership. Fractional ownership through structures like Pacaso involves an actual deeded interest, however small, in the property itself. The court found that difference significant enough to place fractional ownership outside the town's definition of a vacation rental.
Does this ruling apply to other Charleston-area islands? The case is specific to Sullivan's Island's ordinance language and is not binding precedent elsewhere, since it's an unpublished opinion. Isle of Palms and other islands have their own short-term rental frameworks, and fractional ownership has operated on Isle of Palms and in Wild Dunes for years under different rules.
Can an HOA or neighborhood covenant restrict fractional ownership even if the town can't? Potentially. This ruling addressed the town's zoning ordinance specifically. Private covenants and deed restrictions are a separate legal question, and a property's specific HOA documents, where they exist, would need to be reviewed independently.
Will Sullivan's Island change its ordinance because of this? That's a decision for town council, not something this ruling resolves on its own. Buyers should treat the current legal picture as active rather than settled and confirm the latest ordinance language directly with the town before making occupancy assumptions.
