National housing analysts continue to debate why homebuilders across America aren’t building more homes despite years of warnings about housing shortages. A recent analysis by HousingWire noted that builders nationally now face a different problem: too much completed inventory and not enough buyers.
Here in the Charleston region, however, the story is far more complicated.
The truth is that the Charleston metro area is no longer one housing market. It has effectively become two distinct and increasingly disconnected markets — one characterized by scarcity, exclusivity, and soaring prices, and another struggling with oversupply, slower sales, and in some cases, declining values.
And local zoning and planning policies are a major reason why.
Charleston County: A Market Defined by Scarcity
In many of Charleston County’s most desirable communities — Mount Pleasant, downtown Charleston, Isle of Palms, Sullivan’s Island, Daniel Island, and much of West Ashley — development restrictions, limited land availability, lengthy approval processes, neighborhood opposition, and increasingly stringent zoning regulations have dramatically constrained new housing supply.
The result has been predictable.
Prices have continued to rise, inventory remains relatively tight, and homeownership in many Charleston County communities has become increasingly unattainable for middle-income families.
For many buyers, especially those seeking homes below $750,000, the answer is simple: they can’t afford Charleston County anymore.
So they leave.
Berkeley County: The Other Extreme
Unfortunately, the pendulum swings sharply in the opposite direction once you cross county lines.
Large portions of Berkeley County, particularly Summerville, Cane Bay, Moncks Corner, Goose Creek, and surrounding areas, have experienced an unprecedented building boom over the past decade.
Thousands upon thousands of homes have been added, with additional large-scale developments continuing to come online.
The consequence? Inventory in many northern submarkets has risen substantially.
In numerous neighborhoods, sellers are now competing against both resale inventory and aggressive builder incentives on brand-new homes. Price reductions have become increasingly common, marketing times have lengthened, and certain communities are experiencing stagnant or even declining home values.
In effect, builders may have created the very oversupply problem that national economists now warn about.
The Traffic Problem Is a Housing Problem
Charlestonians often discuss traffic as if it exists independently from housing policy.
It doesn’t.
The region’s infamous congestion is, in many ways, a direct result of our zoning extremes.
When Charleston County restricts housing production through stringent zoning, density limitations, and lengthy entitlement processes, workers and families are pushed farther from employment centers.
Meanwhile, when Berkeley County approves large-scale subdivisions at a pace infrastructure struggles to match, residents often find themselves commuting 30, 40, or even 50 miles each day.
The result is exactly what we see today:
Longer commutes.
Overcrowded roads.
More congestion on Interstate 26, Highway 17A, Clements Ferry Road, Highway 41, and US 52.
And increasing frustration for residents across the region.
Simply put, we have created a metropolitan area where jobs, housing, and transportation planning are increasingly disconnected.
The Missing Middle
What Charleston desperately needs is balance.
The region doesn’t need unlimited growth everywhere, nor does it need development paralysis.
Instead, local leaders should focus on creating more “missing middle” housing options — thoughtfully designed townhomes, cottages, condominiums, duplexes, and mixed-use developments located closer to employment centers and existing infrastructure.
Strategic density in appropriate locations could help relieve pressure on both housing affordability and transportation networks.
Without such changes, Charleston risks continuing down a path where the peninsula and coastal communities become the exclusive domain of the ultra-wealthy while northern suburbs absorb ever-expanding growth and increasingly uneven housing performance.
That isn’t healthy for buyers.
It isn’t healthy for sellers.
And it certainly isn’t healthy for regional mobility.
The Charleston region has long benefited from growth. But growth without coordinated planning ultimately creates winners, losers, and gridlock.
Increasingly, that’s exactly what we’re seeing.
The question now is whether local policymakers are willing to acknowledge that Charleston’s housing market has already split in two — and whether they are prepared to do anything about it.
