Summary
In unincorporated Charleston County, a fence over 6 feet tall triggers the general building permit requirement under the county's adopted building code. Fences at or under 6 feet are exempt from that permit under Sec. 4-20, § 105.2, but the exemption never waives compliance with zoning setbacks or other ordinance provisions the Building Official still enforces.
105.1 Required Permits. Any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure, or to erect, install, enlarge, alter, repair, remove, convert or replace any electrical, gas, mechanical or plumbing system, the installation of which is regulated by "this code", or to cause any such work to be done, shall first make application; to the Building Official and obtain the required permit. ... 105.2 Work exempt from permit. Exemptions from permit requirements of "this code" shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of this code or any other laws or ordinances of this jurisdiction. Permits shall not be required for the following: Building: 1.One-story detached accessory structures used as tool and storage sheds, playhouses and similar uses, provided the floor area does not exceed 120 square feet (11 m 2 ).2.Fences not over 6 feet (1829 mm) high.

Full Breakdown
Charleston County adopted its current building code by Ordinance No. 2283 on March 26, 2024, codified at Chapter 4 of the County Code. 1 requires anyone who intends to construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure to first file an application with the Building Official and obtain a permit before starting work. 1 requirement and needs Building Official sign-off before construction starts. 2 is explicit that an exemption 'shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of this code or any other laws or ordinances of this jurisdiction,' so a permit-exempt fence still has to meet whatever height, setback, or vision-clearance standards apply under the county's separate zoning rules. 5). 4.
Violations & Fines
Building work performed without a required permit, including an over-height fence installed without Building Official approval, is a misdemeanor under Sec. 4-30, § 115.1.1. Absent a more specific penalty, § 115.4.1 subjects the violation to the maximum fine and jail time a South Carolina magistrate's court may impose, and § 115.1.3 makes each day the violation continues a separate offense. The county may also seek injunctive relief to force compliance.
