Home Improvement Costs in South Carolina

Labor and material costs in South Carolina run 6% below the national average, based on our regional cost index.

Updated August 2026

Figures below apply our South Carolina regional index to each guide’s national range. The index comes from the U.S. Bureau of Economic Analysis’s Regional Price Parities by State — a real, sourced government figure, not a guess — though it measures overall regional price levels rather than construction costs specifically. See our methodology for how it’s used and its limitations.

Labor market

Below the national average, with coastal areas (Charleston, Myrtle Beach) running higher than inland parts of the state.

Climate considerations

Hurricane and wind exposure along the coast requires wind-rated roofing in many jurisdictions; humid summers keep AC demand consistently high.

Permitting

Coastal counties have wind-mitigation requirements that add inspection steps beyond a standard remodel permit.
