Charleston Short-Term Rental Rules: A Neighborhood-by-Neighborhood Guide
What Buyers, Sellers & Investors Need to Know About Short-Term Rentals in the Charleston Area
If you've ever looked at buying a property in Charleston as a vacation rental, you've probably discovered something very quickly:
Short-term rental rules in Charleston are complicated.
And there isn't one set of rules for the entire Charleston area.
A property in Downtown Charleston can have completely different requirements from a property just a few miles away in West Ashley. A home in James Island could be governed by the City of Charleston, the Town of James Island, or unincorporated Charleston County depending on its exact location.
The same is true on Johns Island.
And then you have separate municipalities such as Mount Pleasant, North Charleston, Sullivan's Island and Folly Beach—each with its own regulations.
This matters enormously if you're buying a property specifically for short-term rental income.
A property that looks like a great Airbnb investment on paper may not actually be eligible for a short-term rental permit.
So, if you're considering a Charleston-area investment property, don't just ask, "Can I do a short-term rental here?" Ask exactly which jurisdiction governs the property, what the zoning is, whether a permit is available, and whether that permit can be transferred or renewed.
Here's an overview of the major Charleston-area markets.
1. Downtown Charleston
Downtown Charleston has some of the most restrictive—and location-specific—short-term rental regulations in the area.
The City of Charleston divides residential short-term rentals into three categories.
Category 1: Old & Historic District
Category 1 applies to properties within the City's Old and Historic District.
For a residential short-term rental to qualify, the STR unit must generally be located in an existing structure or accessory building that is individually listed on the National Register of Historic Places.
Only one short-term rental unit is permitted per property, and an additional off-street parking space is required.
Category 2: Other Parts of the Peninsula
Category 2 generally applies to residential properties on the Charleston peninsula outside the Old and Historic District and outside the Short-Term Rental Overlay.
Again, only one residential STR unit is allowed per property, and an additional off-street parking space is required.
There's another important requirement: the STR unit must be located in a building that is at least 50 years old.
Commercial STRs
There is also a commercial STR category within the City's designated Short-Term Rental Overlay and certain commercial zoning districts.
Commercial STRs don't have the same owner-occupancy requirement as residential STRs, which makes them particularly important to investors.
However, the commercial property must meet the City's zoning requirements and other restrictions. Up to nine STR units may generally be permitted on one lot before an accommodations-use approval is triggered.
The Big Takeaway
Downtown Charleston is not a market where you should assume that any house can legally become an Airbnb.
The property's age, historic status, zoning, location within or outside the overlay and owner-occupancy status can all matter.
2. West Ashley
West Ashley is interesting because the answer depends on which side of the jurisdictional line the property is on.
If the property is inside the City of Charleston, West Ashley falls under the City's Category 3 residential STR rules.
Category 3 includes West Ashley, James Island, Johns Island and Daniel Island that are within the City of Charleston.
Under the City's Category 3 rules, a residential property may generally have one STR unit, and the property must provide an additional off-street parking space beyond the parking required for the existing use.
For example, a single-family home requiring two parking spaces would generally need three spaces if it has an STR unit.
The City also requires a short-term rental permit and business license.
Most importantly, the City of Charleston's residential STR system is based on owner-occupied primary residences, with the property generally needing to qualify for the County's 4% legal-residence tax exemption. Investment properties are generally not eligible for residential STR permits, although commercial STRs in the appropriate overlay/zoning districts are treated differently.
But here's the catch:
Not all of West Ashley is inside the City of Charleston.
If you're looking at a property in unincorporated Charleston County, you may be dealing with the County's Limited Home Rental, Extended Home Rental or Commercial Guest House regulations instead.
That can produce a very different investment opportunity.
3. James Island
James Island is another area where buyers need to be careful about jurisdiction.
There are properties within the City of Charleston, properties within the Town of James Island, and properties in unincorporated Charleston County.
Those three situations should not be treated as interchangeable.
For properties within the City of Charleston, James Island is Category 3 and follows the City's residential STR requirements.
For properties in unincorporated Charleston County, the County's STR regulations apply.
The County currently recognizes three primary STR categories:
Limited Home Rental (LHR)
Owner-occupied properties may rent for up to 72 days per calendar year, with individual stays of no more than 29 consecutive days.
Extended Home Rental (EHR)
Owner-occupied or non-owner-occupied properties may rent for more than 72 but no more than 144 days per calendar year, provided the property qualifies under the applicable zoning and receives the required approvals.
Commercial Guest House (CGH)
These are properties in certain commercial zoning districts and may have substantially different requirements and rental-day limitations.
All Charleston County STR properties require a zoning permit and business license, and the permits must be renewed annually.
For an investor, that distinction can be huge.
A $700,000 house in one jurisdiction might have very different rental potential from a similar $700,000 house a few blocks away.
4. Johns Island
Johns Island follows the same basic jurisdictional issue as James Island.
If the property is within the City of Charleston, it falls under the City's Category 3 regulations.
If it is in unincorporated Charleston County, the County's STR regulations apply.
The City's Category 3 rules allow one residential STR unit per property and require an additional off-street parking space.
In unincorporated Charleston County, the property must qualify under the applicable zoning district and STR category.
The County's rules are particularly important for investors because an Extended Home Rental can be available to non-owner-occupied properties, subject to zoning and approval requirements, and can allow up to 144 rental days per year.
This is one reason I wouldn't lump "Johns Island" into one single STR category when analyzing an investment.
The exact parcel matters.
5. Daniel Island
Daniel Island is also included in the City of Charleston's Category 3 area.
That means the City's Category 3 residential STR requirements generally apply to properties within the City.
The property can generally have no more than one residential STR unit and must provide the required additional off-street parking.
However, Daniel Island has another consideration that buyers should investigate carefully:
Private restrictions.
Even if a property is legally eligible under the City's STR ordinance, an HOA, condominium association or other private covenant may impose additional restrictions.
In other words:
City approval does not automatically mean HOA approval.
That is an important distinction when purchasing a condo or property within a planned community.
6. Mount Pleasant
Mount Pleasant has its own short-term rental permitting system.
Property owners who want to use a residential home, accessory dwelling or portion of a home as a short-term rental are required to have a short-term rental permit and business license.
And Mount Pleasant has implemented a permit/wait-list system, making availability of a permit an important consideration for buyers.
The Town's current STR page states that owners interested in renting their homes, ADUs or bedrooms on a short-term basis can request placement on the STR wait list.
That makes Mount Pleasant very different from simply buying a property and assuming you can immediately begin operating it as an Airbnb.
Buyers should verify:
Whether the property currently has an STR permit
Whether that permit can continue after a sale
Whether the property is eligible for renewal
Whether the property is on the Town's wait list
Whether the HOA permits STRs
Whether the property has a valid Certificate of Occupancy
Mount Pleasant's regulations have also evolved over the years, so relying on an old listing description that says "Airbnb allowed" isn't enough.
7. North Charleston
North Charleston has its own STR ordinance and permitting process.
Short-term rentals are allowed as a conditional use of legally established dwelling units, subject to specific requirements.
Some of the requirements include:
Maximum occupancy of two people per bedroom
Maximum of eight overnight guests
Required off-street parking
No street parking for STR guests or owner vehicles during the rental
No weddings, parties or similar events
A city STR permit
An active business license
Posting the STR registration number
Payment of applicable taxes
Annual renewal
A local contact who can respond and be on-site within 30 minutes when required
The City states that a separate STR permit and business license are required for each STR unit. STR permits are renewed annually by February 28, while the associated business license is renewed by April 30.
North Charleston is therefore another market where the economics of a potential STR need to be evaluated together with the property's zoning and permit status.
8. Sullivan's Island
Sullivan's Island has its own vacation-rental regulations and is considerably more restrictive than many people realize.
The Town requires a Certificate of Zoning Compliance and Vacation Rental Business License for a property to operate as a vacation rental.
The regulations also establish occupancy, parking and rental-period requirements.
Among the current requirements, vacation rentals generally must have a written lease, provide off-street parking for vehicles associated with the rental and have a minimum rental period of three continuous nights. Occupancy is limited to no more than 12 occupants, with additional restrictions on total people gathered at the property.
The Town can also suspend or revoke a vacation-rental authorization for violations.
And there is an especially important provision for investors: the Town's ordinance provides that abandoning the vacation-rental use for 12 consecutive months can result in loss of the right to continue using the property as a vacation rental.
That means buyers should never assume that a property that was once operated as a vacation rental automatically retains that right indefinitely.
9. Folly Beach
And then there's Folly Beach—which currently has perhaps the most significant STR story in the Charleston area.
Folly Beach voters approved an 800-license cap on non-owner-occupied/investor short-term rentals in 2023.
But in August 2026, a Charleston County judge ruled that the voter-approved cap was illegally adopted because the referendum process was improperly used for matters involving business licenses and taxation.
The judge also struck down the City's short-term rental registration fee as an unauthorized tax.
This does not mean that Folly Beach is suddenly an unrestricted STR market.
As of August 19, 2026, City Council voted to appeal the ruling and moved toward a temporary moratorium on most new STR applications while the City's ongoing STR study is completed.
This is one market I'm watching very closely.
Depending on the outcome of the appeal and the City's eventual replacement ordinance, the value of existing STR properties—and the opportunities available to future investors—could change significantly.
For now, I would consider Folly Beach a highly uncertain regulatory environment rather than assuming that the 800-property cap is permanently gone.
The Most Important Lesson for Charleston-Area Buyers
If you're considering purchasing a property as a short-term rental, don't start with Airbnb. Start with the jurisdiction.
Before you make an offer, determine:
1. Who governs the property?
Is it:
City of Charleston?
Town of Mount Pleasant?
City of North Charleston?
Town of Sullivan's Island?
City of Folly Beach?
Town of James Island?
Unincorporated Charleston County?
2. What is the zoning?
A property may be located in an area where STRs are common but still be in a zoning district where the use isn't permitted.
3. Is there currently an STR permit?
If there is, determine exactly what type of permit it is and whether it survives a sale.
4. Is the permit transferable?
Never assume this.
A short-term rental license can be one of the most valuable characteristics of an investment property, but its value depends on the rules governing that particular license.
5. Does the HOA allow it?
A city or county permit doesn't override private covenants.
6. How many days can you actually rent?
"STR allowed" and "STR allowed 365 days a year" are two very different investment propositions.
Charleston County, for example, has a 72-day category, a 144-day category and a commercial category with different rules.
7. What happens if the rules change?
This is perhaps the most important question of all.
Short-term rental regulations across the Charleston area have changed substantially over the past several years, and several municipalities continue to evaluate their policies.
Why This Matters When Buying Charleston Real Estate
I've seen buyers look at a property and calculate their purchase decision based on projected Airbnb income without first confirming whether the property can legally operate as an STR.
That's backwards.
The legal ability to generate the income needs to be established before the income is used to justify the purchase price.
And this is particularly important in Charleston because two homes that look nearly identical on a map can have completely different rental rules based solely on their jurisdiction, zoning or HOA restrictions.
The Charleston area continues to be one of the country's most popular vacation destinations, so I don't expect the conversation around short-term rentals to disappear anytime soon.
Instead, I expect the regulations to continue evolving.
For buyers, sellers and investors, the smartest approach is to understand the rules before making a purchase decision—not after.
Thinking About Buying a Charleston-Area Investment Property?
If you're considering buying a property specifically for short-term rental income, I'd be happy to help you evaluate the property from a real-estate perspective—including the jurisdiction, existing rental status, potential rental strategy and how regulatory changes could affect the investment.
And if you're already a Charleston-area property owner considering selling, the STR status of your property may be an important part of its marketability and value.
