Commerce City, CO Sign Regulations: Window Signs (2026)

Sec. 21-8450 governs permanent window signs and Sec. 21-8550 governs temporary window signs in the Commerce City Land Development Code, sitting in Article VIII, Divisions 4 and 5. Both sign types share the same placement rules: they must be located only in the windows of the unit or space occupied by the business, cannot be displayed above the ground floor level, and cannot be animated. Sec. 21-8550(1)(c) also treats any neon sign connected to an interior electrical outlet as a temporary window sign for coverage purposes.

The two sections set different maximum coverage percentages: Sec. 21-8450(1)(d) caps a permanent, temporary, or combined window sign display at 25 percent of an individual window's area, while Sec. 21-8550(1)(e) sets the cap for the temporary standard at 35 percent of the window. Window signs are not permitted at all in residential zoning districts; the use is limited to commercial and non-residential tenant space. Temporary window signs are not subject to a permit or a maximum number under the code's general temporary-sign framework, unlike other temporary sign types such as banners or inflatable signs, which require permits and carry day limits.

Because window signage is regulated separately from a business's other permanent signage allowance under Sec. 21-8400, it does not count against a tenant's wall sign or freestanding sign area, so long as the window coverage percentage itself is respected.
