Summary
Within Berkeley County's arterial road overlay corridors, window signage is folded into the wall-sign limit: combined wall and window coverage can't exceed 20 percent of the wall it's displayed on, per County Code of Ordinances § 10.3.3(B).
(B)Wall signs. Wall signage is permitted at the rate of one square foot of signage per linear foot of building width of that wall to which the signs are attached. No single wall sign may exceed 200 square feet. The aggregate wall signage plus window signage will not exceed 20 percent of that wall area to which the signs are attached.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 37).
Full Breakdown
2 (parcels fronting I-26, I-526, US 17A, US 52, US 176 and the other named county arterials). Wall signage is permitted at one square foot of sign area per linear foot of the building wall width to which the signs attach, and no single wall sign may exceed 200 square feet. " Window signs are therefore not measured against a separate window-only limit; they draw down the same 20-percent-of-wall ceiling as painted or mounted wall signs. 3(C): no more than one displayed at a time, no more than six in any 12-month period, each capped at 12 square feet, banners limited to messages like "Grand Opening" or "Sale," and any temporary sign restricted to 30 consecutive days on display.
A business stacking permanent wall graphics, window decals and a banner promotion on the same storefront wall has to keep the combined coverage, permanent and temporary alike, inside that 20 percent ceiling. The rule was adopted with the rest of the overlay subchapter under Ordinance No. 09-11-55 (2009) and later amended by Ordinance No. 10-10-34 (2010).
Violations & Fines
Section 10.3.3 carries no dedicated fine schedule, so an oversized wall-plus-window sign display falls to the county's general penalty at § 1-8: up to a $500.00 fine, up to 30 days imprisonment, or both, with each day of continued violation treated as a separate offense. The zoning administrator's office reviews sign permits and enforces the overlay's signage article.
