Dorchester County, SC Fence Regulations: Height Limits (2026)

7 of the Zoning and Land Development Standards governs fences and walls in every district except jails and penitentiaries, which are exempt outright. A general provision applies to all fences: for any fence within twenty-five feet (25') of a lot line, the finished side of the fence must face that lot line, so neighbors and the street see the finished face rather than the structural rails or posts. Height limits then vary by use. Residential uses are capped at a maximum height of eight feet (8'), except where a taller fence is required for screening in the affected district.

Commercial front-yard fences and walls are capped at the same eight feet (8') within required and provided front yards, while commercial side- and rear-yard fences and walls may rise to ten feet (10'), two feet taller than what is allowed facing the street. Civic and institutional uses are held to the residential standard of eight feet (8'), while agricultural and industrial uses are permitted the full ten feet (10') on every side, reflecting the larger equipment and livestock containment needs of those uses. These are maximum heights measured for the fence or wall as constructed; a property owner who wants a taller residential fence for screening purposes must show it falls within a screening requirement specifically imposed by the district, since the general 8-foot cap is otherwise fixed.
