Charleston, SC Fence Regulations: Height Limits (2026)

Table 3.1 of the zoning ordinance sets Charleston's baseline height, area, and setback regulations, and Footnote 16 to that table carries the fence rule. Outside Board of Architectural Review (BAR) jurisdiction, a residential fence or freestanding wall may not exceed six feet. Inside a residential zoning district that falls under BAR review, the city's historic and older neighborhoods, the limit is seven feet for the fence panel and eight feet for a masonry pier. The ordinance grandfathers what is already built: an existing fence or wall may be restored, or extended in length, up to the height it already has, even if that exceeds the current cap.

A second, separate limit governs corners. Section 54-351 bars any fence, wall, shrubbery, sign, or other obstruction between three and fifteen feet in height from standing inside the vision clearance triangle, measured back fifteen feet from the intersection of two street or railroad rights-of-way and connecting those points. Traffic and directional signs are exempted. Section 54-506(e) allows a narrow exception for a corner-lot building that replaces one removed within the prior twelve months to keep the same side-street position, but that exception does not touch the vision-triangle obstruction ban itself.

Homeowners in a BAR district need a certificate of appropriateness before building or replacing a fence past six feet; those outside BAR jurisdiction still need a permit under Section 54-903 before construction begins. The Zoning Administrator, in the Department of Planning and Preservation, reviews plans and can require a fence to be lowered or moved if it violates the height cap or blocks the corner sightline.
