What Are South Carolina Impact Fees?
The South Carolina Development Impact Fee Act (S.C. Code §§ 6-1-910 et seq.) governs local impact fees, requiring capital improvements plans and limiting fees to a development's proportionate share. Utility capacity fees from commissions of public works and regional sewer authorities add the utility side.
Coastal growth — Charleston's tri-county market, Myrtle Beach's Horry County, and Hilton Head's Beaufort County — drives the state's most substantial fee programs. South Carolina figures on impactfees.org are model estimates for early budgeting; verify adopted schedules and utility capacity fees locally.
South Carolina figures are illustrative estimates from our statewide cost model — calibrated to local construction costs and community size — rather than verified fee schedules. Use them for early budgeting and site comparison, and see our methodology for how estimates are built.
