Valuation limits
South Carolina's Real Property Valuation Reform Act generally limits taxable-value growth to 15% over five years at reassessment; the cap is removed for an assessable transfer of interest and generally does not cover new construction, additions, or improvements. Owner-occupied legal residences use the 4% assessment ratio; other real property generally uses 6%.
