Sign Regulations in North Charleston, SC

If you live in North Charleston or are thinking about moving there, sign regulations are one of those things you probably won't think about until they affect you directly. North Charleston has 2 specific rules on the books covering different aspects of sign regulations, and some of them might surprise you.

Digital Billboards

North Charleston bans construction of any new billboard, digital or static, under its zoning code, with narrow relocation rights only into designated billboard plazas along freeways and arterials.

Key details: Rule: New billboards banned citywide. Existing billboards: May continue if legally permitted. Relocation: Only within designated billboard plazas. Threshold: Display face over 32 sq ft. Enforcement: Zoning administrator (director).

Erecting an unpermitted billboard is enforced by the zoning administrator; violators must remove the sign, and decisions may be appealed to the Board of Zoning Appeals before circuit court review.

Compared to other cities, North Charleston takes a harder line on digital billboards. The enforcement and penalty structure reflects that.

Window Signs

In North Charleston's commercial and industrial districts, combined wall and window signage on any building facade can't exceed fifteen percent of that facade's area, under Appendix A, Zoning Regulations Section 8-11(e)(2). The cap applies to wall-plus-window signage together, not window signs alone, across the ON, B-1, B-2, CRD, M-1 and M-2 zones.

Key details: Facade coverage cap: 15% of facade area, wall plus window combined. Applicable zones: ON, B-1, B-2, CRD, M-1, M-2 districts. Wall sign projection limit: No more than 12 inches from the wall. Height limit, first-story use: Cannot rise above the second-story window sill. Measurement rule: Window and wall sign modules combine in one calculation.

A facade that exceeds the combined 15 percent wall-and-window cap is out of compliance the moment it's installed, and the director can deny or revoke the sign permit under Section 8-4(h). A sign left nonconforming or abandoned more than 45 days after abandonment draws a fine of up to $500 plus up to 30 days' imprisonment under Section 8-6(c), with each additional day treated as a separate offense.
