Clemson's short-term rental ordinance was, according to the city's own summary, "enacted in 2015 in response to concerns about permitting short-term residential rentals." That's the whole backstory. What it does in practice is cap every registered short-term rental at 25 rental days per calendar year, per dwelling. Not per season. Not per football schedule. Per year.
That single number is the reason a lot of out-of-market buyers arrive in Clemson with a spreadsheet that doesn't survive contact with the city's zoning office. The pitch usually goes something like this: buy a house within walking distance of campus, rent it out for home games, parents' weekend, graduation, maybe a few Master's-adjacent weekends in Augusta traffic overflow, and let the nightly rate cover a meaningful chunk of the mortgage. Seven home Saturdays a year, a couple of three-night graduation stretches, and the math looks fine on paper. It falls apart the moment you check how many nights of short-term occupancy the city will actually let you register.
Two Rental Ordinances, Not One
Clemson runs two separate rental systems, and buyers who assume they're the same thing tend to get surprised. The long-term Rental Housing Ordinance, adopted by City Council in 2000 and updated multiple times since, covers single-family houses, duplexes, and townhouses rented for standard lease terms. Owners need a permit, an annual inspection, and a $125 fee, and the permit cycle runs from July 1 through June 30 each year. Maximum occupancy is set by the zoning district the property sits in, not by a fixed number tied to bedroom count, so the city's Zoning and Codes Administrator is the one who can confirm what a specific address actually allows.
The Short Term Rental Ordinance is a different program entirely, built for the 2015 concerns mentioned above rather than for long-term leasing. Registration and inspection run on their own cycle, from April 15 to April 14, with a separate annual fee. Owners have to post a visible sign, keep a guest log, and if the property isn't owner-occupied, designate a responsible person within a set radius of the city who can be reached if something goes wrong. These aren't cosmetic requirements. They're the mechanism the city uses to keep short-term rentals from quietly turning a residential block into something closer to a hotel row, and the 25-day annual cap is the part of that mechanism that actually limits revenue.
The Cap That Kills the Football-Weekend Spreadsheet
Run the calendar and the cap gets tight fast. A three-night stay for each of seven home football Saturdays already burns 21 of your 25 days, before graduation weekend, before Family Weekend, before anything else. Buyers who plan around a full home schedule plus a few university event weekends will hit the ceiling before the semester is over, and the city's ordinance doesn't offer a seasonal exception or a larger allotment for university-adjacent addresses. The cap is the same whether the house is three blocks from Memorial Stadium or on the edge of town.
Occupancy adds a second constraint on top of the day count. For owner-occupied short-term rentals, the city caps occupancy at two persons per bedroom plus two additional occupants, up to ten people total, which is generous enough for a group of alumni splitting a game weekend. For non-owner-occupied properties, though, occupancy follows the zoning district instead, and in a number of Clemson's residential zones that limit runs as low as two unrelated occupants. An investor buying a four-bedroom house purely as a short-term rental, with no plan to live there, may find the zoning district caps the guest count well below what the bedroom layout would suggest, regardless of what the 25-day allowance would otherwise permit.
Two Price Numbers That Don't Agree
Buyers layering rental math onto a purchase price also run into a second kind of friction: which price to actually use. Over the three months ending in May 2026, homes in Clemson sold at a median of $424,000, up 16.1 percent from the same period a year earlier, with homes moving in an average of 49 days. That's a hot, fast-moving number built from actual closed transactions in a narrow window.
Zillow's broader home value index, which smooths across a much wider set of properties and a longer time horizon, put the average Clemson home value at $410,904 as of the end of July 2026, up only 1.2 percent over the prior year. The two numbers aren't contradicting each other so much as measuring different things. The three-month transaction median captures whatever mix of homes happened to sell recently, which in a lower-volume month can be skewed by a handful of larger or newer properties. The broader index is closer to what a typical Clemson home, sampled across the whole market, is actually worth. A buyer using the recent transaction median as their appraisal benchmark risks anchoring to a hotter number than the comps will support, especially if the recent sales sample was thin. Sixty-three homes sold in Clemson in May 2026, down from 99 in the same month a year before, which means that 16.1 percent year-over-year jump is riding on a smaller, and potentially less representative, set of closings than it was built on the year prior.
Who's Actually Buying Here
The buyer pool behind those numbers has a shape worth understanding before you price a listing or plan a resale timeline. Looking at the fourth quarter of 2025, 45 percent of people searching for Clemson homes were also looking to move out of the area, while the other 55 percent wanted to stay within the same metro. Of the buyers coming from outside the region entirely, Atlanta sent more house-hunters into Clemson than any other metro, followed by Asheville and Washington.
That matters for two different kinds of sellers. If you're marketing a property to the local, staying-in-metro half of that buyer pool, the pitch is about proximity to campus, walkability, and daily convenience. If you're positioning for the incoming Atlanta or Asheville buyer, the pitch is closer to relocation and second-home framing, since that buyer is coming from outside the market and evaluating Clemson against wherever they're leaving. An agent who treats both halves of that buyer pool the same way is leaving positioning on the table.
The Long-Term Permit as the Practical Alternative
For buyers whose numbers don't work under a 25-day cap, the long-term rental path is usually the more realistic strategy, and Clemson's academic calendar makes the timing fairly predictable. This year's cycle ran fall move-in from August 12 through 15, spring move-in from January 3, and spring move-out in early May, and that same rhythm repeats every academic year. A property registered under the long-term Rental Housing Ordinance, with its annual permit and inspection cycle running July through June, lines up naturally with that turnover pattern, and it sidesteps the day-count ceiling entirely since long-term leases aren't subject to the short-term cap.
The tradeoff is that long-term tenancy income looks different from short-term nightly rates, and the zoning-based occupancy limits still apply. A buyer deciding between the two models is really deciding between a smaller number of high-rate, tightly capped nights and a steadier, lower-rate lease that runs most of the year. Neither is inherently better. They're just different instruments, and the ordinance that governs each one is the reason the choice matters more in Clemson than it would in a market without a university calendar shaping demand.
A Few Direct Questions
Does the 25-day cap apply to the property or to the owner? It's tied to the dwelling itself, so owning multiple registered short-term rentals doesn't pool the day count across them, but each individual property is still limited to 25 days a year.
Can I live in the house part-time and rent it the rest of the year? That's closer to a second-home purchase than a straight investment property, and it can come with more favorable financing. Freddie Mac's conforming guidelines allow up to 90 percent loan-to-value for a second home, which can lower the upfront cash needed compared to a dedicated investment-property loan. The occupancy math also shifts in your favor, since owner-occupied short-term rentals get the more generous two-per-bedroom-plus-two allowance instead of the tighter zoning-based limit.
What if I only want student tenants on a normal lease? That's the long-term Rental Housing Ordinance, not the short-term program, and it comes with its own permit, its own annual inspection, and its own zoning-based occupancy cap. The city's Zoning and Codes Administrator can confirm the specific limit for an address before you make an offer, which is worth doing at the offer stage rather than after closing.
The city keeps its rental rules published for exactly this reason. You can review the details directly on Clemson's Rental Housing page before writing an offer that assumes more rental flexibility than the ordinance actually allows.
If you're weighing a Clemson purchase against how the numbers actually pencil out under the city's rental rules, Southern Real Estate and Development can walk through the permit paths, the zoning-based occupancy limits for a specific address, and what the current comps really support before you write an offer.
