How Charleston County Property Assessments Work

Charleston County property assessments follow South Carolina’s market value standard, meaning appraisers estimate the price a parcel would bring on the open market. Appraisers compare each parcel to recent comparable sales, then adjust for location, square footage, condition, and improvements. Agricultural parcels may qualify for a special use value based on income-producing capacity rather than market price. Mobile homes are titled through the South Carolina Department of Motor Vehicles and are valued separately from real estate.

Assessment Components

1. Market value: estimated open-market selling price
2. Capped value: limited-growth figure used for tax purposes
3. Taxable value: amount subject to millage after exemptions
4. Use value: agricultural value based on production capacity

Each component plays a specific role in the final tax bill. The capped value is what most residential owners actually pay tax on, the market value serves as a reference for limit enforcement.
