Window Sign. 1. Window signs are permitted for all nonresidential uses in all districts. 2. All window signs, whether temporary or permanent, are limited to no more than 30% of the surface of each window area. Window area is counted as a continuous surface until divided by an architectural or structural element. Mullions are not considered an element that divides window area. 3. An illuminated window sign is permitted but limited to a maximum area of six square feet. This is included in the maximum 30% calculation. Such sign cannot flash. 4. Window displays of items sold in the store are not considered window signs.

Full Breakdown
Zoning Code Sec. N permits window signs for all nonresidential uses in every zoning district, but caps coverage at 30% of the surface of each window area. The ordinance defines 'window area' as a continuous surface counted until it is divided by an architectural or structural element, and it specifically states that mullions, the thin strips separating window panes, do not count as dividers, so a multi-pane storefront window is still measured as one continuous surface for the 30% calculation. Illuminated window signs are allowed but face an added cap: a maximum of six square feet, a limit that is folded into, not added on top of, the overall 30% ceiling.
An illuminated window sign also cannot flash. Merchandise displayed in a store window, such as products for sale arranged for viewing, is not counted as a window sign at all and falls outside these limits entirely. Because the rule applies only to nonresidential uses, a home occupation window is not subject to the 30% cap under this section. Businesses in the C-MX, MU-T, industrial, and other commercial districts most commonly rely on window signs for sale announcements, menus, and seasonal promotions within these bounds.
Violations & Fines
A window sign that exceeds 30% of the window surface, or an illuminated window sign larger than six square feet or one that flashes, is a zoning violation subject to the Zoning Officer's enforcement process and the City's general penalty under Sec. 1-17: up to a $2,000 fine, 90 days in jail, or 90 days of community service.
