Brookhaven, GA Sign Regulations: Window Signs (2026)

Chapter 21 of the Brookhaven Code defines a window sign broadly. Under § 21-2 it is any sign placed inside a window, within two feet of a window, or upon the window panes or glass, either inside or outside the building, that is visible from the exterior of the structure. The same definition sets the cap: window signs shall not cover more than 30 percent of the total window area per façade of a business. Section 21-62(2) repeats the cap in the list of prohibited signs, which includes window signs that exceed 30 percent of the total window area per façade of a business. The chapter defines façade as the exterior wall of a building or tenant space.

Window signs are exempt from the permit requirement under § 21-60(1), but the exemption keeps them subject to all other provisions of the chapter. Section 21-66(7) adds that window signs are only allowed on the ground floor of a building.

The dimension tables in § 21-72 print different window figures. Table 21-72(a), for nonresidential uses not developed as a planned commercial center, lists the window sign column at 10% of the window space. Table 21-72(b), for a lot developed as a planned commercial center, lists 30% of the window space for buildings under 50,000 sq. ft. and 10% of the window area for buildings 50,000 sq. ft. or over. Both tables print N/A for the maximum number of window signs. A planned commercial center is a commercial, office, industrial or mixed-use development with a common entry from a public street that is managed as a whole. Because the 30 percent definition and the table figures are printed side by side in the same chapter, a business owner planning window graphics should ask the director of the community development department which figure applies to the lot before printing anything.
