In 2026, a professional paver driveway in Charleston and Mt. Pleasant typically costs between $12 and $35 per square foot. For a standard 600-square-foot two-car driveway, homeowners should budget $7,500 to $22,000. These costs are driven by Charleston’s unique requirement for advanced soil stabilization (to counter settling) and strict municipal ordinances regarding impervious surface limits and historic district aesthetics.
2026 Charleston Pricing by Material
Because Charleston has a more diverse architectural landscape, material choice often hinges on your specific neighborhood’s requirements.
- Traditional Pavers: $12 – $20 per sq. ft.
- Antique & Clay Brick: $18 – $30 per sq. ft.
- Permeable Pavers: $20 – $32 per sq. ft. (Essential for meeting Charleston County’s strict 40% impervious surface limits).
- Historic Cobblestone: $35 – $60+ per sq. ft. (Labor-intensive restoration-grade work).
Technical Challenge: The “Pluff Mud” Foundation
In Charleston, the “base” is the most expensive part of the project. Unlike the sandy, self-draining soil of the Southern Lowcountry, Charleston’s silty clay is prone to “heaving” and settling.
1. Advanced Soil Stabilization
To prevent your driveway from sinking or rutting, a professional Charleston install in 2026 requires:
- Sub-grade Excavation: Removing 12–14 inches of soft soil.
- Triaxial Geogrid: A high-strength structural grid placed beneath the stone base to distribute vehicle weight across the soft soil.
- Thickened Base: A minimum of 8–10 inches of compacted GAB (Graded Aggregate Base).
2. The 40% Lot Coverage Limit
The City of Charleston and Mt. Pleasant enforce strict Maximum Impervious Surface Coverage (typically 40%–45% of the lot). If your new driveway pushes you over this limit, you must use Permeable Pavers or face a “Zoning Variance” process that can take months.

Frequently Asked Questions (FAQ)
Do I need a permit for a driveway in Charleston?
Yes. You will typically need a Zoning Permit and, if your home is in a designated district, a Board of Architectural Review (BAR) or Design Review Board (DRB) approval. Additionally, any new curb cut requires an Encroachment Permit from the City or SCDOT.
Frequently Asked Questions
Poured concrete slabs are rigid. When Charleston’s soft soil shifts, concrete cracks. An interlocking paver system is flexible; it moves with the soil without losing structural integrity. If a tree root or “Pluff Mud” pocket causes a dip, individual pavers can be lifted, the base re-leveled, and the same pavers reinstalled.
Yes, but only if they are Permeable Pavers. Under current Charleston County Stormwater Manuals, permeable systems with an open-graded stone reservoir are often credited as “pervious,” allowing you to stay in compliance without reducing the size of your driveway.
The humidity can lead to “Lowcountry Green” (mold/mildew). We recommend using SEK-SureBond Polymeric Sand to lock out moisture and weeds, followed by a professional cleaning and sealing every 3 years to protect against UV and salt-air erosion.
