Isle of Palms Short-Term Rental Rules: What Buyers and Investors Need to Know
If you're considering buying an investment property on the Isle of Palms, short-term rental regulations should be one of the first things you investigate.
Unlike some Charleston-area communities that have moved toward tighter restrictions or caps on vacation rentals, Isle of Palms has continued to allow short-term rentals throughout the city.
But that doesn't mean every property automatically qualifies.
The City has a specific licensing system, zoning requirements, occupancy limitations and renewal requirements that can have a major impact on the value and income potential of a property.
Isle of Palms Does Allow Short-Term Rentals
The City of Isle of Palms defines a short-term rental as a dwelling rented for three months or less. Property owners who rent residential units—including houses, condos and apartments—are required to obtain an Isle of Palms short-term rental business license.
This is an important distinction for buyers.
You shouldn't assume that because a property is located on a popular vacation island it automatically has the right to operate as an STR.
The property's zoning, existing license and compliance with the City's requirements all need to be verified.
Isle of Palms Rejected a Proposed STR Cap
One of the biggest differences between Isle of Palms and Folly Beach is what happened when the communities considered limiting the number of investor-owned vacation rentals.
In November 2023, Isle of Palms voters rejected a proposed cap of 1,600 short-term rentals.
The measure would have limited the number of investor-owned STRs while exempting owner-occupied rentals from the cap.
The referendum failed, with approximately 54% of voters voting against the proposed limitation.
That means Isle of Palms did not move forward with that proposed citywide cap.
This is particularly important when comparing the Isle of Palms market with nearby Folly Beach.
Folly Beach adopted an 800-license cap through referendum, which has now become the subject of a significant legal battle. Isle of Palms voters, on the other hand, rejected a proposed cap.
But There Are Still License Caps in Certain Areas
This is where things get a little more complicated.
Although Isle of Palms does not have the proposed citywide investor cap, the City's zoning ordinance contains Short-Term Rental Zones and license caps within those zones.
The City's code establishes specific STR zones and provides for maximum numbers of properties that can be licensed for STR use within those zones. Licenses are generally distributed on a first-come, first-served basis, with existing license holders receiving preference for renewal when they remain in good standing.
So when evaluating a property, the question isn't simply:
"Are short-term rentals allowed on Isle of Palms?"
The better question is:
"Is this specific property eligible for a short-term rental license, and does it already have one?"
That distinction can make a substantial difference in an investment analysis.
Existing STR Licenses Can Be Extremely Important
If you're purchasing an Isle of Palms property that is already being operated as a legal short-term rental, you want to carefully investigate the property's licensing history.
The City requires STR licenses to be renewed annually, with the license year running through April 30. The City's regulations give existing license holders preference for renewal when the license is in good standing.
This means the license isn't simply something to think about after closing.
It can be an important part of the property's investment profile.
Before purchasing, I would want to confirm:
Is there currently a valid STR license?
Is the license in good standing?
Has the property had any violations?
Is the license associated with the property or the owner?
What happens to the license when ownership changes?
Is the property located within an STR zone?
Is the property's current use consistent with its zoning?
What are the property's permitted occupancy limits?
These questions should be answered before making an offer based on projected rental income.
Occupancy Rules Matter
Isle of Palms also has specific occupancy regulations.
The City's ordinance establishes maximum overnight occupancy based on factors including the number of bedrooms and the size and history of the property. Different rules can apply depending on whether the property had a valid STR license before June 22, 2010, whether it was constructed after that date, and whether it has subsequently been altered or reconstructed.
That history can matter.
For example, two houses with the same number of bedrooms and similar square footage may not necessarily have identical permitted occupancy.
That's another reason I would not rely solely on an Airbnb listing or the number of guests a previous owner accommodated.
Legal occupancy and advertised occupancy aren't necessarily the same thing.
Wild Dunes Is Another Layer
If you're considering a property inside Wild Dunes, there's another issue to investigate.
Wild Dunes properties can be subject not only to the City of Isle of Palms' regulations but also to private community or association restrictions.
In other words, even if the City allows the property to operate as a short-term rental, private covenants or association rules may impose additional restrictions.
This is an important distinction throughout the Charleston area:
Government approval does not override private restrictions.
A buyer should review the applicable HOA or community documents before assuming an STR is permitted.
What Makes Isle of Palms Interesting for Investors?
From an investment standpoint, Isle of Palms is particularly interesting because it remains one of the Charleston area's strongest vacation-rental markets while avoiding the citywide investor cap that voters rejected in 2023.
That doesn't eliminate regulatory risk.
But it does mean that the market currently looks very different from places such as Folly Beach, where the legality of the existing cap is now being litigated.
For buyers, that can create an interesting opportunity—but it also makes due diligence extremely important.
What Should You Look for When Buying an Isle of Palms STR?
If you're buying specifically for short-term rental income, I'd put these items at the top of the checklist:
1. Verify the STR license
Don't simply accept the seller's statement that the property is "Airbnb approved."
Verify the license directly with the City.
2. Verify the zoning
Determine which zoning district the property is located in and whether the STR use is permitted there.
3. Determine whether the property is within an STR zone
The City's regulations establish designated STR zones and associated licensing caps.
4. Verify occupancy
Determine the property's legally permitted overnight occupancy rather than relying on the number of guests shown in a rental listing.
5. Review the property's rental history
Look for previous violations, complaints, license suspensions or other compliance issues.
6. Check HOA and community restrictions
This is especially important for condos and properties within communities such as Wild Dunes.
7. Understand what happens after the sale
Before assigning a value to an STR license, determine exactly how the City's rules treat a change in ownership.
8. Run conservative numbers
Don't base your purchase price on a best-case Airbnb projection.
Consider occupancy, management fees, cleaning costs, insurance, taxes, maintenance, utilities, HOA fees and the possibility of future regulatory changes.
Isle of Palms vs. Folly Beach
The contrast between these two neighboring beach communities is fascinating.
Isle of Palms:
Voters rejected a proposed 1,600-property cap in 2023. The city continues to license STRs, subject to its zoning, licensing and occupancy regulations.
Folly Beach:
Voters approved an 800-license cap in 2023, but a 2026 court ruling found the referendum-based cap illegal. The city has appealed and is considering a temporary moratorium while it works through the legal and regulatory issues.
For investors, these are two very different regulatory stories happening just a few miles apart.
And that is exactly why Charleston-area buyers need to understand the rules on a property-by-property basis.
The Bottom Line
If you're looking at Isle of Palms as a short-term rental investment, I would not characterize the market as "unrestricted."
It is better described as a regulated STR market without the proposed citywide investor cap.
The City requires licenses, has designated STR zones, regulates occupancy and has mechanisms for enforcement and license renewal.
At the same time, Isle of Palms remains an attractive market for vacation-rental investors because voters rejected the proposed 1,600-license cap in 2023.
For anyone considering buying an Isle of Palms property, the most important thing is to determine what the property can legally do today—and what rights, if any, come with the property when it changes hands.
That information can be worth tens or even hundreds of thousands of dollars when you're evaluating the value of a vacation-rental property.
