The Rule That Built Sullivan's Island's Price Premium Just Met Its First Real Test

Drive down I'on Avenue on Sullivan's Island and you will pass yard signs that read "Stop Timeshares on Sullivan's." They have been there for years, planted by a resident named Tim Emrich after a California company called Pacaso bought a house on the street and began selling it in eighths. The signs are still up. They are up because in February 2026, a South Carolina appeals court ruled that Emrich's side lost.
That ruling matters to anyone comparing Sullivan's Island to its neighbor across Breach Inlet, Isle of Palms, because it touches the one mechanism that has quietly done more to shape Sullivan's Island pricing than any dune, porch, or live oak canopy: the island's ban on short-term rentals.
Both islands sit off Mount Pleasant. Both face the Atlantic. Both carry flood risk that any buyer's insurance agent will flag in the first phone call. Yet in 2025, Sullivan's Island closed the year with a median sale price around $4.2 million according to Charleston Trident Association of Realtors data, while Isle of Palms closed near $2.66 million, up sharply for the year but still a fraction of its neighbor's number.
That gap is not simply "Sullivan's is nicer." Isle of Palms has its own oceanfront estates, its own golf resort at Wild Dunes, its own stretch of Millionaire's Row. The gap has more to do with who is allowed to buy, and why.
Sullivan's Island banned short-term vacation rentals around 2001, a restriction old enough that most current buyers have never known the island any other way. Isle of Palms took the opposite path. It permits licensed short-term rentals, with occupancy limits, parking rules, and a required 24-hour contact for complaints. That single difference in policy has produced two different buyer pools for two decades. Sullivan's Island attracts people planning to live in the house or hand it down. Isle of Palms attracts that buyer too, but also the investor underwriting rental income against the mortgage.
Inventory reflects the split. Sullivan's Island typically has fewer than 20 to 30 active listings at any given time, a market so thin that a single high sale can swing the median. Isle of Palms carried well over a hundred active listings as of late 2025. One island trades in a trickle. The other trades in a stream.
The case that just tested this arrangement involved a property owned by an entity called 2 SC Lighthouse, LLC and managed through Pacaso, a company that sells fractional shares of vacation homes, letting buyers purchase one-eighth or one-quarter interests and split calendar time among owners. In October 2022, the town's zoning administrator, Charles Drayton, notified Pacaso that the arrangement violated the island's rental ban. The town's Board of Zoning Appeals agreed. So did the Charleston County Circuit Court.
Pacaso and the LLC appealed again, represented in part by attorney and Charleston City Councilman Ross Appel, arguing that selling ownership shares is not the same as renting a room. On February 18, 2026, the South Carolina Court of Appeals sided with them in a 2-1 decision. The court's reasoning turned on a distinction that sounds technical but carries real weight: the people staying in the house are owners, not tenants. There is no landlord-tenant relationship and no payment for temporary lodging, so the town's definition of a short-term rental, written decades before fractional platforms existed, does not reach the arrangement. As one finding in the case record put it, the ownership structure "does not constitute commercial use of the property."
The opinion is unpublished, meaning it does not set binding precedent for future cases. But it stands as the current legal word on how Sullivan's Island's ordinance applies to fractional ownership, and the town cannot enforce its old rule against this business model unless it rewrites the rule itself.
The town has started that process. Planning Commission records from March 2026 show a workshop specifically to discuss proposed amendments to the zoning ordinance sections that define rentals, a direct response to the ruling. Whether that amendment closes the gap the court identified, or invites another round of litigation, is not yet settled.
If you are weighing a purchase on Sullivan's Island against one on Isle of Palms, the Pacaso ruling is not a footnote. It is a live variable in the exact mechanism that has kept Sullivan's Island prices where they are.
The island's premium has rested on more than scarcity. It has rested on the promise that your neighbors are homeowners, not a rotating set of eighth-share guests. That promise, in the eyes of the Court of Appeals, has a legal seam. A well-structured co-ownership arrangement can currently sit on a single-family lot and function, day to day, closer to a small hotel than a household, without technically breaking the town's ordinance.
For a buyer this raises a few practical questions worth asking before you write an offer, not after:
None of this changes the fundamentals that make Sullivan's Island desirable. Fixed land supply, strict architectural review, and a low-turnover market are not going anywhere. But a buyer who assumes the "no rentals, ever" story is airtight is working from an outdated picture. The more accurate picture, as of August 2026, is that the rule exists, is actively enforced against traditional short-term rentals, and has one court-recognized exception that the town is actively trying to close.
Isle of Palms buyers, by contrast, are underwriting a market that has never pretended to be rental-free. If you want licensed rental income as part of your ownership calculus, that conversation is straightforward on Isle of Palms and legally uncertain on Sullivan's Island. If you want the opposite, a neighborhood insulated from that kind of turnover, Sullivan's Island still delivers it more reliably than almost anywhere else in the Lowcountry. Just know the insulation has a documented crack in it right now.
One more detail worth knowing before you run numbers on either island: Charleston County completed a property reassessment in 2025, and South Carolina taxes owner-occupied primary residences at a 4 percent assessment ratio, exempting them from school operating millage, while second homes and investment properties are assessed at 6 percent. That difference compounds the ownership-structure question. A fractional share, a rental property, and an owner-occupied home are not just different lifestyles. They carry different tax treatment, and the county assessor's office can give you a property-specific estimate before you close.
Can I still buy a home on Sullivan's Island and rent it out short-term? No, unless the property was operating as a rental before the island's ban took effect around 2001 and has maintained that status continuously. The February 2026 ruling did not overturn the short-term rental ban itself. It found that one specific ownership structure, fractional co-ownership through a platform like Pacaso, falls outside the ban's legal definition.
Does this ruling apply to Isle of Palms or other Charleston islands? No. It interprets Sullivan's Island's own zoning ordinance. Isle of Palms already permits licensed short-term rentals under its own rules, so the fractional ownership question does not carry the same stakes there.
Is the ruling final? It is the current governing decision, issued by the South Carolina Court of Appeals in a 2-1 split. It is unpublished, which means it is not binding precedent for other cases, but it controls how Sullivan's Island's ordinance is read today. The town's Planning Commission began discussing a zoning amendment in response the following month.
Should this change how I think about buying on Sullivan's Island? It should change what you ask, not necessarily what you decide. A buyer's agent who understands this history can help you check ownership structure on a specific listing and its neighbors before you commit, which is a different level of diligence than a standard title search.
Sullivan's Island and Isle of Palms both reward patience and the right local read.
