Summary
In unincorporated Greenville County, a window sign placed within 12 inches of the glass is exempt from a sign permit, but County Code § 19-42(c) caps combined exempt and permitted window signage at 20 percent of the window area. Bigger storefront displays count as permitted signs and fall under the Business Use Area table's 20 percent, 225-square-foot ceiling in § 19-55(b)(4).
(a) General.
(3) No exempt sign shall be located within twenty-five (25) feet of the property line or street right-of-way whichever is greater.
(4) No copy on an exempt sign shall exceed six (6) inches in height.
(c) Exempt window signs.
(1) Exempt window signs may be placed within twelve (12) inches of the window, on the interior of the window or the exterior of the window.
(2) Exempt window signs in combination with permitted window signs shall not exceed twenty (20) percent of the window area.
Full Breakdown
Chapter 19's Article III exempts a narrow category of signs from the county's sign permit under § 19-32, and window signs are one of them. Under § 19-42(c), an exempt window sign can sit on the interior or exterior of the glass or anywhere within 12 inches of it, but exempt window signage combined with any permitted window sign on that same pane cannot exceed 20 percent of the window area. The exemption also carries the article's general conditions: no exempt sign, window signs included, may sit within 25 feet of the property line or the street right-of-way, whichever is greater, and copy on an exempt sign cannot exceed 6 inches in height.
Once a business wants window signage beyond the exempt 20 percent threshold, that signage becomes a permitted sign requiring a county permit. In Business Use Areas, § 19-55(b)(4)'s sign table caps permitted window signs at up to three per property, 20 percent of the window area, 225 square feet maximum, and no higher than the roofline. Residential Use Area properties get no separate window sign allowance at all outside a home occupation's own signage rule. Because window signs are measured against the glass itself rather than the building's wall area, a business with several storefront windows can spread its coverage across multiple panes as long as each pane individually stays within the percentage cap.
Violations & Fines
The Codes Administrator or a designee enforces Chapter 19 and can issue a written notice of violation for window signage that exceeds the exempt or permitted coverage limits. Under § 19-32(f), a first violation draws a civil penalty of up to $200, and the owner gets seven calendar days to correct it or submit an acceptable correction plan before a second citation issues. Each day a violation continues after that is a separate offense, punishable by a civil penalty of up to $2,000 per day, with the right to contest the citation before the county magistrate.
