Glendale, AZ Sign Regulations: Window Signs (2026)

311(K) governs window signs as a distinct Building Sign category: 'No permit required,' but 'The area covered by window signs shall not exceed thirty percent (30%) of the exterior window area,' with window area counted as one continuous surface until an architectural or structural element divides it, and mullions do not count as a divider. The same 30% cap applies separately to required doors: window signs on required doors cannot exceed 30% of the glass area of that door. The section closes two coverage loopholes: perforated or semi-opaque window graphics, such as one-way vision film, count toward the 30% cap exactly the same as fully opaque paint or vinyl, and any sign placed inside a building specifically to be viewed from the public right-of-way is treated as a window sign subject to the same limit even if it is not physically attached to the glass.

Window signs are only allowed for multi-family and non-residential uses, and only on the ground floor; they cannot be used on individual multi-family tenant windows. 311 that allow internal or external lighting. 307(A)(3), using the smallest rectangle enclosing the sign copy and any distinctive background.
