Caddo Parish, LA Sign Regulations: Window Signs (2026)

Section 9.6 of the Caddo Parish Unified Development Code lists the sign types that are allowed without going through the sign permit process, and window signs are one of them. Under subsection C.11, window signs are permitted for all non-residential uses in every zoning district, whether the sign is a permanent decal or a temporary paper poster taped up for a sale. The coverage limit applies to both: no window sign, temporary or permanent, may cover more than 30% of the surface of each window area.

The Code defines window area as a continuous glass surface that runs until it is broken up by an architectural or structural element, such as a wall or a change in the building facade; mullions, the thin dividing bars within a single window unit, do not count as a dividing element, so a multi-pane storefront window is measured as one continuous surface for the 30% calculation rather than pane by pane. Window signs may be lit either internally or externally, and there is no numeric cap on how many window signs a business can display so long as the combined coverage across each window stays under the 30% threshold.

Because window signs fall under the no-permit list in Section 9.6, a business does not need a sign permit application, but the sign still has to meet every general standard in Article 9, including the ban on flashing or moving signs and the prohibition on sign copy that could be confused with a traffic control device. The Zoning Administrator, who enforces the sign article under UDC Article 19, can order removal or correction of a window sign that exceeds the coverage limit.
