The first thing a King Street shopkeeper will tell you about Charleston is that the city does not run on a single clock. Spoleto crowds fill the sidewalks in late May while a rental two blocks off the Battery sits half-booked in January, and both of those facts are true about the same zip code in the same year. Hosts who file Charleston under one tidy number, borrowed from a beach town two bridges away or a StaySTRA roundup that never mentions Category 1 parking, end up pricing a market they have not actually looked at.

This report exists to give Charleston hosts and buyers a standalone read on the peninsula city — not Folly Beach, not Isle of Palms, not the leftover Mount Pleasant figure that keeps getting mistaken for the city mean. Two independent data sources disagree on the annual number here, and rather than split the difference into a fake average, this report names both, dates them, and lets a host decide which one matches the listing they actually run. This is not legal advice.

What the numbers actually say

AirROI's Charleston, SC extract, covering August 2025 through July 2026 and last updated August 8, 2026, puts the typical active listing at about $65,541 in annual revenue across 1,924 tracked units. Occupancy on that sample runs 48.9%, average daily rate is $432, and RevPAR comes in at $219. Entire home or apartment listings make up 89.8% of that supply, houses account for 51.7% of it, and the average listing sleeps 5.1 guests. Supply on the peninsula grew 6.6% year over year on that same extract, and the typical guest books about 61 days out.

StaySTRA's 2026 investment roundup reports a different Charleston: roughly $84,843 a year, built from an ADR near $420 and occupancy around 55%, across a sample of about 2,136 listings. That is meaningfully higher than the AirROI figure, and the two samples are not the same size, the same window, or necessarily the same geography — StaySTRA does not publish the same peninsula-specific detail AirROI does. This gap is wide enough that averaging the two would produce a number neither source actually reported. The honest move is to hold them as a range — call it roughly $65,500 to $85,000 depending on source and vintage — and re-check both pages before repeating either figure in a listing description or an investor conversation.

A third number that gets mistaken for Charleston's is Mount Pleasant's. AirROI's Mount Pleasant page, same August 2025–July 2026 window, shows about $52,782 a year on 460 tracked listings, occupancy 50.3%, ADR $329. That is a real number for a real market — it just is not this one. Mount Pleasant sits across the Cooper River, has its own zoning desk, and its ADR runs roughly $100 lower than the peninsula's. Filing it as Charleston's mean flattens two different towns into one, and it undersells what a well-positioned peninsula listing can actually charge.

Why the range exists instead of one number

Part of the spread between AirROI and StaySTRA is almost certainly sample composition. AirROI's 1,924-listing extract skews toward entire-home units in a market where 89.8% of active supply is already whole-house or whole-apartment stock, which tends to pull ADR toward the middle of the market rather than the high end. StaySTRA's larger sample and higher ADR figure could reflect a different scrape date, a different geographic boundary, or simply a different mix of listing types weighted toward premium historic-district units. Neither source is wrong on its face — they are measuring overlapping but not identical things.

What both sources agree on, even where the dollar figures diverge, is that Charleston commands a premium ADR relative to most Southeast coastal markets, and that the peninsula's booking window runs long — guests are planning Charleston trips roughly two months out, which gives a host real room to adjust pricing and minimum stays before a date locks in.

The regulatory frame the AirROI scrape does not carry

AirROI's own listing for Charleston includes a generic "low regulation" tag, and that line is doing real damage if a host takes it at face value. The City of Charleston runs one of the more structured residential short-term rental frameworks in the region, built around a simple governing idea: the host has to prove the property is their primary residence, verified through Charleston County's 4% legal-residence assessment. Investment properties — homes the owner does not live in — are not eligible for the city's residential Categories 1 through 3 at all. That single fact reshapes who this market is actually open to.

Category 1 covers the Old and Historic District on the peninsula, and it is narrow: the unit has to sit in a structure individually listed on the National Register, the city caps it at one STR unit per property, and it requires off-street STR parking on top of the household's own parking. Category 2 covers the rest of the peninsula, outside both the Old and Historic District and the Short Term Rental Overlay, and it requires the building to be at least 50 years old, again capped at one unit with its own parking stack. Category 3 is the off-peninsula city footprint — West Ashley, James Island, Johns Island, Daniel Island — also capped at one unit per property.

There is a fourth lane worth knowing about even though it is not the residential path: the Short Term Rental Overlay, a commercial strip centered on Cannonborough-Elliotborough, where commercial STR and bed-and-breakfast operations run under zoning rules that are entirely separate from the 4%/primary-residence categories. A host researching "Charleston STR rules" who lands on Overlay language without knowing it does not apply to a residential Category 1–3 property is reading the wrong page for their situation.

This is not legal advice — a host should confirm parcel eligibility, category, and permit status directly with the City of Charleston before listing a property, and questions about the category framework can start with the Citizen Services desk at 50 Broad Street or shorttermrental@charleston-sc.gov.

Calendar shape: where the money actually concentrates

On the AirROI extract, April is the strongest revenue month, with March and May close behind — a spring run that peaks right as Spoleto Festival USA opens. Spoleto runs May 22 through June 7 in 2026, a 17-day stretch per the festival's own site, and it anchors a genuine demand spike layered on top of an already-strong spring season. The softest stretch on the same extract falls in January, with February and July also reading as shoulder months — July's dip driven less by a lack of visitors than by Lowcountry humidity pushing some leisure travel toward the coast or indoors.

A host pricing a full year off a single blended ADR is leaving April and May money on the table and overpricing January. The shape of Charleston's calendar rewards a listing calendar that tightens minimum stays around Spoleto and early spring, then actually drops price and minimum-night requirements in the January trough rather than holding peak-season rates through a month that will not fill at that price.

Supply growth and what a 6.6% increase actually means

The AirROI extract shows Charleston's active listing count growing 6.6% year over year, which is a meaningful but not runaway pace for a market this established. That growth is happening against a supply base that is already 89.8% entire-home or entire-apartment units — this is not a market where a spare room is competing for attention. New entrants are, by and large, listing whole houses or whole apartments into a field of whole houses and whole apartments, which means differentiation has to come from something other than unit type.

Average guest capacity across the sample sits at 5.1, which tracks with Charleston's mix of Charleston Single houses, carriage houses, and multi-bedroom off-peninsula homes rather than studio-style units. A listing built for two guests is competing in a smaller lane than the market average suggests, and a listing that can credibly sleep six or more is closer to the center of demand than a host might assume from national Airbnb marketing, which tends to spotlight smaller urban units.

None of this changes the underlying math — it just means a host weighing whether Charleston is "getting crowded" should look at what kind of supply is actually growing. A 6.6% increase in whole-home listings inside a market already dominated by whole-home listings is a story about more competition within the same lane, not a story about a fundamentally new kind of listing stock entering the picture.

A host's self-diagnosis: which number is actually yours

Neither $65,541 nor $84,843 is a promise, and the more useful exercise than picking one is asking which sample a given listing more closely resembles. A whole-house or whole-apartment Category 1, 2, or 3 property, professionally photographed, priced to move in the January trough rather than held at peak rates, sits squarely inside the kind of listing AirROI's 1,924-unit extract is built from — that figure is the more conservative, better-documented anchor for a typical operator in this market.

A listing that skews toward the top of the market — a fully renovated Charleston Single in the Old and Historic District, a carriage house with a private courtyard, or any property that routinely commands rates well above the $432 blended ADR — has a real case for expecting something closer to StaySTRA's higher figure, but that case has to be earned through actual booking history, not assumed from the address alone. A host who has not yet tested peak Spoleto pricing, has not built review volume, or is still calibrating minimum-stay rules around the January hole has not yet demonstrated which end of the range their property belongs in.

A quick self-check: does the listing sleep close to the market's 5.1-guest average, or is it a smaller unit competing against a supply base that is 89.8% entire-home stock? Is the property eligible under Categories 1 through 3 as a verified primary residence, or does it depend on the separate commercial Overlay path? Has the host actually priced the spring run — March through Spoleto's early-June close — at a premium, or is a single blended rate quietly leaving April money on the table? Answering these honestly does more to locate a specific property inside the range than any citywide average can.

Year one versus year three: how the range actually gets earned

A brand-new Charleston listing with no operating history has no business assuming it will land at StaySTRA's end of the range in its first twelve months. Year one is largely about calibration — learning where the property actually sits relative to the spring peak, the Spoleto spike, the July humidity dip, and the January trough, and building the review count that later lets a listing command a rate above the blended market ADR. Treating AirROI's more conservative, better-itemized figure as the year-one target, rather than the headline number from either source, sets an expectation a new listing can plausibly clear.

By year two or three, a listing that has correctly priced its calendar — protecting the spring and Spoleto weeks, discounting the January hole instead of holding peak rates through it, and accumulating enough reviews to rank well in search — has a legitimate path toward the higher end of the range, and in a strong year, toward or past StaySTRA's figure. That trajectory is not automatic. It is the direct result of a host doing the work this report and its companion posts describe: matching listing copy to the categories the city actually recognizes, pricing the calendar to the shape of demand rather than a flat annual rate, and treating each season's actual performance as the input for the next season's pricing rather than repeating the prior year's numbers by default.

The practical takeaway for anyone comparing their own results against this report a year from now: a property that is underperforming even the conservative AirROI range after a full calendar cycle likely has a fixable problem — pricing, photos, category mismatch, or a calendar that is not respecting the spring-versus-January split — rather than a market that quietly changed. Charleston's demand shape is well-documented enough, across two independent sources, that a listing tracking meaningfully below both figures is usually telling a host something about execution, not about the city.

Reading the two-source gap as a buyer, not just a host

For a host who already owns a Charleston property, the AirROI-versus-StaySTRA gap is mostly an exercise in caution — pick the source that best matches your listing type and stay skeptical of either extreme. For someone evaluating whether to buy into this market, the gap matters more, because it changes the return math meaningfully depending on which figure gets plugged into a pro forma. Underwriting off StaySTRA's $84,843 and landing closer to AirROI's $65,541 is the kind of gap that turns an attractive number into a disappointing first year.

The more defensible approach for a prospective buyer is to treat AirROI's figure as the conservative anchor — it is the more heavily documented of the two, with a published sample size, occupancy, ADR, and RevPAR all itemized on the same page — and treat StaySTRA's higher number as an upside case rather than a baseline expectation. A property that clears the AirROI range comfortably and might reach the StaySTRA range in a strong year is a much safer bet than a property that needs the higher number just to pencil.

It is also worth remembering that both figures describe averages across hundreds or thousands of listings with wide variation in location, condition, and marketing quality. A well-photographed, well-priced Category 1 property in the Old and Historic District with strong reviews is not obligated to perform at either average — it can outperform both, just as a poorly marketed listing in the same category can underperform. The market report sets the range; the individual listing's execution decides where inside that range — or outside it — a given property actually lands.

What this means for a host or buyer sizing the market

A buyer or host evaluating Charleston in 2026 has two honest numbers to work from, not one comfortable blend: AirROI's roughly $65,541 on a 1,924-listing base, and StaySTRA's roughly $84,843 on a differently-built sample. Neither should be presented as gospel, and neither should be quietly rounded up or down to match a pitch. The more useful exercise for an individual property is pulling that property's own trailing twelve months, if it has operating history, and comparing that actual performance against both ranges rather than assuming either one applies directly.

The regulatory layer matters just as much as the revenue layer here. A number this strong is only reachable if the property actually qualifies under Categories 1, 2, or 3 — or sits in the Overlay under a commercial path — and an investment property that does not meet the primary-residence test is not eligible for the residential lane at all, regardless of what any revenue estimator projects for the address.

This report is meant to be a starting point, not a substitute for a host's own numbers. A property with even six months of operating history has more predictive power for that specific address than either citywide average, and the next post in this series walks through how to turn that history into listing copy, pricing bands, and a calendar strategy that fits Charleston's actual demand shape instead of a generic Southeast coastal template.

Frequently Asked Questions

How much does a Charleston, SC Airbnb actually make in a year?

Two credible sources disagree. AirROI's August 2025–July 2026 extract shows about $65,541 a year across 1,924 active listings, occupancy 48.9%, ADR $432. StaySTRA's 2026 investment roundup shows about $84,843 on a larger, differently-built sample. Treat this as a range tied to two dated sources rather than one fixed figure, and re-check both before quoting a number.

Is Charleston's short-term rental market the same as Mount Pleasant's?

No. Mount Pleasant sits across the Cooper River with its own zoning desk and its own AirROI figure — about $52,782 a year on 460 listings, ADR $329, in the same window used for Charleston. That is a real number for a different town. Filing it as Charleston's mean understates what the peninsula actually charges.

Does the City of Charleston really require a host to live in the property?

For the residential Categories 1 through 3, yes. The city verifies primary residence through Charleston County's 4% legal-residence assessment, and investment properties that do not meet that test are not eligible for those residential categories. This is not legal advice — confirm eligibility directly with the city before listing.

What is the difference between Category 1, 2, and 3 in Charleston?

Category 1 covers the Old and Historic District peninsula and requires the structure be individually listed on the National Register. Category 2 covers the rest of the peninsula outside that district and the Overlay, requiring a building at least 50 years old. Category 3 covers off-peninsula city areas like West Ashley, James Island, Johns Island, and Daniel Island. All three cap a property at one STR unit.

What is the Short Term Rental Overlay and does it apply to my house?

The Overlay is a commercial strip centered on Cannonborough-Elliotborough where commercial STR and bed-and-breakfast operations run under separate zoning rules. It is not the same framework as the residential Categories 1 through 3, so a homeowner outside that commercial strip should not assume Overlay rules govern their listing.

When is Charleston's slowest month for bookings?

January reads as the clear trough on the AirROI extract, with February and July also running softer than the spring peak. July's softness tracks with Lowcountry humidity more than a lack of visitors overall.

Should I use AirROI's 'low regulation' tag when deciding whether to list in Charleston?

No. That generic tag does not reflect the city's actual framework — the primary-residence requirement, the three residential categories, and the separate commercial Overlay are all real constraints that a blanket regulation label misses entirely.

Is Spoleto Festival actually worth building a calendar around?

Spoleto runs May 22 through June 7 in 2026 and lands right at the tail of Charleston's strongest natural season, April through May. It is worth protecting on the calendar, but a host should verify exact festival dates and event details on the organizer's own site each year rather than assuming they repeat.

How does Charleston's booking window compare to a typical beach market?

The AirROI extract shows a roughly 61-day typical booking window for Charleston, which is longer lead time than many drive-to beach markets see. That gives a host more runway to adjust pricing and minimum stays before a date locks in.

Can an investment property owner still list in Charleston at all?

Not under the residential Categories 1 through 3, which require primary-residence status. An investor should confirm directly with the City of Charleston whether the Short Term Rental Overlay's commercial path applies to their specific parcel — this is not something to assume from a general reading of the rules.
