Beaufort County, SC Sign Regulations: Window Signs (2026)

Section 5.6.180 of the Community Development Code establishes the Window Sign Type, defined as lettering "applied directly on the inside of a window." Subsection B sets the coverage math: "Per Shop front Bay 25% max. Per Shop front 15% max." A business may cover up to a quarter of any single storefront bay with window lettering, but total window signage across the whole shop front cannot exceed 15 percent of that frontage. Dimensionally, each window sign is capped at "Width 5' max." and "Height 36" max."

Placement rules require signs to sit at or above eye level and to be "applied directly to the inside of the glass," ruling out signs suspended or floated inside the window. The code discourages a common shortcut: "Applied plastic or vinyl cut letters are strongly discouraged." It also requires that "window signs must have a clear background," meaning opaque backing panels behind the lettering are not allowed. The provision notes the format is meant for "small professional offices" and storefronts with several divided window openings, cautioning that "repetition should be done with great care to ensure that the entrance to the business is clearly marked" when the same message repeats across multiple panes.

Window signs sit within Division 5.6 (Signs) of the Community Development Code, so violations run through the same general sign permitting and enforcement machinery, including the permit-tag and impoundment procedures of Section 5.6.70.
