Summary

Dorchester County requires a Special Area Permit before any construction, alteration, or nearby development affecting a National Historic Landmark, National Register property, or culturally significant site listed under Section 11.3.2, including places like Old Dorchester, Middleton Place, and the Summerville Historic District.

These county ordinances apply to unincorporated areas of Dorchester County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Prior to the issuance of a Building, Zoning or Sign Permit by the Department of Planning and Codes Enforcement, a Special Area Permit shall be required for: (a) The construction, erection, reconstruction, exterior rehabilitation, remodeling, alteration, or restoration of any building, structure, or property listed in Sec. 11.3.2 of this Ordinance; (b) Any development that, by the creation of vibration, air emissions, noise or odor, would in all likelihood produce physical alterations to any of the properties listed in Sec.11.3.2 of this Ordinance, or substantially impair the use and enjoyment of such properties or districts by the citizens of Dorchester County; or (c) Any development of properties, that would be visible from the ground level of a landmark or property situated in a designated historic district or from any significant property listed in Section 11.3.2, up to a radius of ten thousand (10,000) feet from such landmark or property.

Full Breakdown

3, Developments Affecting Historic and Culturally Significant Properties, of the Zoning and Land Development Standards Ordinance (Ord. No. 3(a) directs the Zoning Administrator to keep a file, description, designation documents, and map for each listed site. 3(b) includes places like Francis Beidler Forest and the Old Dorchester County Hospital. 4 requires a Special Area Permit, obtained before any Building, Zoning, or Sign Permit, for three triggers: construction or exterior alteration of a listed property itself; development likely to cause vibration, emissions, noise, or odor that could physically alter or impair enjoyment of a listed property; or any development visible from ground level of a listed landmark within a 10,000-foot radius.

5(b) layers on added standards: no structure may exceed three stories or the height of the surrounding tree canopy, whichever is lower, and within 100 feet of the Ashley River or its abutting wetlands, tree removal requires a Landscape Plan prepared by a registered Landscape Architect and approved by the Zoning Administrator.

Violations & Fines

Section 11.3.9 treats unpermitted development activity affecting a listed historic or culturally significant property as creating a risk of irreparable damage, and directs the Sheriff of Dorchester County to order such activity to cease immediately, with the Zoning Administrator and County Attorney authorized to seek immediate injunctive relief. Because this sits within the broader Zoning Ordinance, a conviction otherwise falls under Section 14.2.4's misdemeanor penalty (SC Code of Laws §6-29-950): a fine up to $200 or up to 30 days imprisonment, with each day of continued violation a separate offense, appealable to the Board of Zoning Appeals within 15 days under Section 14.3.1(b).
