Charleston uses form-based zoning in its historic core and certain new neighborhoods, regulating building form, frontage, and street relationship rather than traditional use-based density and setback rules.
Charleston's Zoning Ordinance Chapter 54 incorporates form-based districts in the Old and Historic District, the Upper Peninsula, and certain redevelopment areas. Rather than separating uses by district, form-based zoning regulates building height, frontage type, lot coverage, and street wall presence. This approach preserves the historic urban fabric on the peninsula while allowing mixed-use development. Outside form-based zones, traditional Euclidean zoning applies with single-family, multi-family, commercial, and industrial districts. Planned Unit Developments (PUDs) allow site-specific zoning agreements for larger parcels.
Zoning violations trigger stop work orders, fines $100-$500 per day, and corrective action requirements. Repeated noncompliance can void certificates of occupancy.
