Summary

In unincorporated Forsyth County, a window sign on a commercial or industrial lot may not exceed 30 percent of the individual window frame it is mounted on, per the Sign Ordinance's zoning-district performance table. The South Forsyth Overlay District is stricter, capping window signs at 20 percent of the total window area under the Unified Development Code.

These county ordinances apply to unincorporated areas of Forsyth County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Full Breakdown

Chapter 66 of the Code of Ordinances (the county's Sign Ordinance) sets window-sign coverage as part of its performance-standards tables for each zoning district. Section 66-113 states that "any sign, regulated by this ordinance, shall comply with the requirements outlined for the zoning district in which the sign is located," and the Commercial or Industrial Zoning Districts table under that section fixes the window-sign standard at "not to exceed 30% of any individual window frame," listed alongside the district's 140-square-foot aggregate sign-face allowance. A separate table for Neighborhood Shopping, Urban Village, Master Planned and Pedestrian-Oriented districts instead limits window signage to 30 percent of total transparent glass area (excluding doors) or one square foot per linear foot of street frontage, whichever is less, and treats any window graphic with lettering taller than one inch mounted within four feet of the glass as a regulated window sign.

15(A) extends Sign Ordinance coverage to displays visible from the property line, not just the public right-of-way, for commercial property in that overlay. Outside a monument sign or an electrically connected sign, a general sign permit is still required under § 66-61 unless the sign type is specifically excluded from the article, with applications filed with the Department of Planning and Community Development under § 66-62. None of this reaches the city of Cumming, which administers its own separate sign code; these standards govern only unincorporated Forsyth County.

Violations & Fines

Erecting or displaying a window sign that exceeds the applicable 30 percent (or 20 percent, in the South Forsyth Overlay) coverage cap is a violation of Article II of Chapter 66. The Director of Planning and Community Development can require correction or removal of a noncompliant sign, and under § 66-101, a sign that does not meet current standards loses its right to be replaced except in conformity with the current article. A permit obtained on a false or omitted material statement can be revoked under § 66-64, and the sign must then come down.

Frequently Asked Questions

How big can a window sign be in unincorporated Forsyth County?
On commercial or industrial lots, window signage cannot cover more than 30 percent of the individual window frame it occupies, under the zoning-district table incorporated by Code of Ordinances § 66-113. Different caps apply in shopping/village districts and the South Forsyth Overlay, so check which district the property sits in.
Are window sign rules different in the South Forsyth Overlay District?
Yes. Unified Development Code § 12-13.15(B) limits window signs there to 20 percent of the total area of each window, tighter than the countywide commercial standard, and the overlay's applicability clause reaches displays visible from the property line, not only the road.
Do these limits apply inside Cumming?
No. Cumming is Forsyth County's only incorporated city and enforces its own sign code. These window-sign coverage limits come from the county's Chapter 66 Sign Ordinance and the county UDC, which govern only unincorporated Forsyth County.
Does a window sign need a county permit?
Under § 66-61, a sign permit is required for signs in the county unless the type is specifically excluded from the article, with applications filed through the Department of Planning and Community Development per § 66-62. Monument signs and electrically connected signs additionally need a building permit under § 66-63.
