Pull up two market trackers for Mount Pleasant this year and you'll get two different stories. Redfin's February 2026 numbers show a median sale price of $831,000, down 7.9 percent from a year earlier, with homes taking 107 days to sell compared to 81 days the year before. Look at a different tracker's spring numbers and the median for the same town jumps past $1.1 million. Both are accurate. Neither is lying to you. And if you're trying to decide whether to buy now or wait for prices to drop further, the gap between those two numbers matters more than either one on its own.
The short version: Mount Pleasant doesn't behave like most Charleston-area suburbs, because it isn't allowed to. The town has spent seven years deliberately limiting how many new homes can be built inside its own borders, and that limit runs through 2029. When supply is capped by ordinance rather than by the market, the usual rules about waiting out a slow season stop applying evenly across the board.
The Ordinance Behind the Headlines
In January 2019, Mount Pleasant Town Council adopted a Building Permit Allocation System, a program that rations new residential building permits on a fixed schedule rather than letting the market issue as many as demand supports. The town extended it in January 2024 for another five years, through 2029. Under the current allocation, the town will issue no more than 2,400 permits for new single-family homes and 500 for multifamily units over that five-year stretch, split into semi-annual batches, with no single subdivision allowed more than 25 single-family permits in any six-month cycle.
The town's own planning department frames the system as a way to keep infrastructure, schools, and roads from falling further behind population growth. Before the caps took effect, Mount Pleasant issued 1,407 new dwelling units in a single year, 2018. The town's goal was to slow annual growth from over 3 percent down to a target of 2.1 percent. The actual result landed lower than the target, bottoming out at 1.29 percent growth in 2020, a year in which just 520 new residences were permitted townwide. A separate, longer moratorium on new apartment and condo construction ran alongside the permit caps from 2017 until it expired at the close of 2024, though the underlying permit ceiling didn't go anywhere when the moratorium ended.
Read the ordinance yourself on the Town of Mount Pleasant's official site, and you'll see the mechanics laid out in plain administrative language. That page is worth five minutes if you're weighing a purchase here, because it's the one document that explains why this market's headline numbers move differently than a neighboring one.
The One Neighborhood That Skips the Line
Here's the detail that surprises most buyers comparing neighborhoods: not every part of Mount Pleasant is under the cap. Carolina Park and Liberty Hill Farm were both exempted when the system was first written, because both developments already had long-term development agreements with the town predating the ordinance. That's why Carolina Park, anchored around Wando High School and a full-service library and hospital campus, has kept adding new construction at a pace the rest of town simply can't match.
Old Village and I'On don't have that exemption, and both are effectively built out anyway. When I'On's first homes went up in 1998, they sold for around $160,000. Those same homes now trade for roughly ten times that. There's no vacant land left inside I'On for the permit system to ration, so its prices move on resale scarcity alone, immune to any supply relief the rest of the town might eventually see. Park West and Dunes West sit somewhere in between: mostly built, with pockets of new attached product still coming online under whatever permits remain in the current cycle.
If you're comparing these neighborhoods on price alone, you're missing the more useful comparison: which ones can still add inventory before 2029, and which ones are permanently capped by geography as much as by ordinance.
What Bracket Are You Actually Shopping In?
The town's median doesn't move as one number. It moves as three separate stories depending on where your budget lands.
| Bracket | Typical range | What's happening in 2026 |
|---|---|---|
| Luxury, mostly waterfront | $2 million and up | Slower sales, longer days on market, real room to negotiate on price and repairs |
| Attached product (condos, townhomes) | $400,000 to $650,000, plus $500 to $800 a month in regime fees | Softening concentrated in listings sitting past 60 days; fresh listings still move |
| Entry-level to mid detached | $700,000 to $950,000 | Still competitive, still seeing multiple offers on anything updated and centrally located |
That middle-of-the-market pattern shows up inside Redfin's own numbers too. The site's average Mount Pleasant house price came in at $880,000 last month, down 8.5 percent year over year, while its median sale price sat lower, at $831,000, down 7.9 percent. An average sitting above the median in the same data set is what happens when a handful of luxury waterfront closings land in the same reporting window as a batch of ordinary detached sales. Look at the Old Village Historic District specifically, where Redfin logged an average house price of $2.85 million last month, down more than 30 percent year over year in a submarket where multiple offers are rare and the total pool of monthly sales is small enough that one or two closings swing the average hard in either direction.
None of this means the town is crashing. A separate January 2026 read put Mount Pleasant's median at $855,000, up 1.12 percent year over year, with only 140 homes sold that month and inventory sitting at a 3.41-month supply. When your entire monthly sample size is under 150 transactions, one heavy month of luxury closings or one light month of entry-level activity moves the headline number more than it would in a larger market. That's not spin. That's arithmetic in a town that has spent seven years making sure the transaction count stays small.
Why the Summerville Playbook Doesn't Transfer
The instinct to wait for a better price makes sense in a market where builders keep adding subdivisions. It's a harder bet here. Compare Mount Pleasant to Dorchester County, home to Summerville, where single-family sales climbed 13.7 percent in early 2026 while the median price held essentially flat near $390,000. That's what unconstrained supply looks like: new product keeps arriving fast enough to absorb demand without pushing the median up. Mount Pleasant can't do that. The permit ceiling is written into town code, the remaining developable land inside the town limits is mostly spoken for outside of Carolina Park and Liberty Hill Farm, and the town's own affordable-housing exemption produced exactly one qualifying project across the permit system's first five-year run, Gregorie Ferry Towns off Highway 41, with townhomes starting at $279,000.
If you're comparing a Mount Pleasant purchase against a Summerville or Cainhoy alternative, the honest version of the tradeoff isn't just price per square foot. It's whether you're buying into a town where new supply can still show up to soften prices, or one where the supply side was legislated shut through 2029 regardless of how the monthly headlines read.
A Few Questions Worth Asking Before You Offer
Does the permit cap mean prices can only go up from here? Not automatically. Specific brackets, particularly luxury inventory over $2 million and aged attached product, are genuinely softening in 2026. The cap limits new supply. It doesn't guarantee demand stays constant, and rate movements or broader economic conditions still affect what buyers are willing to pay.
Are condos and townhomes really the workaround they look like? Partly. Entry prices in the $400,000 to $650,000 range are real, but regime fees running $500 to $800 a month change the monthly math enough that a lower-priced attached home can cost about the same each month as a detached house several hundred thousand dollars higher. Run the full monthly number, not just the purchase price, before assuming attached product is the cheaper path.
What happens when the cap expires in 2029? The ordinance itself doesn't say. Past extensions suggest the town has been willing to renew rather than let the caps lapse outright, and the amount of genuinely developable land left inside Mount Pleasant's borders is limited regardless of what the ordinance allows. Anyone timing a purchase around a 2029 supply release should treat that as a possibility worth watching, not a plan to build around.
Reading a Mount Pleasant listing against a townwide median is like reading a restaurant's average entree price without knowing whether you're ordering the burger or the whole fish. The number on the portal is true. It just isn't the number that applies to your specific offer.
