Wyoming, MI Sign Regulations: Window Signs (2026)

Section 90-708 of the Wyoming Zoning Ordinance sets the window sign rules for nonresidential districts. Subsection (1)(c) points to Table 90-708-2, and that table marks a permanent window sign as permitted (P) in all seven districts: B-1, B-2, B-3, RO-1, I-1, I-2 and I-3. Section 90-701 defines a window sign as a sign located in or on and affixed to a window that is intended to be viewed from the outside. A permanent sign that is not affixed directly to a window, or that is positioned next to a window so it is visible from outside, counts as a wall sign instead and falls under the wall sign allowance.

The area cap is the number that matters. Table 90-708-2 says the total of all window signs and banners cannot exceed 15% of the total wall frontage area per business, and footnote (e) to Table 90-708-4 repeats that the total of all window signs, temporary and permanent, cannot exceed 15 percent of the total wall frontage area. Footnote (i) makes window signs and wall banners share one pool: the wall frontage area taken up by both together cannot exceed 15 percent. Under section 90-705, when lettering or logos are printed, painted or mounted on a window, the sign area is measured by enclosing the edges of the letters and logos in a parallelogram or rectangle.

Permits split by sign type. Section 90-708(1)(a) requires a sign permit for every permanent sign, and section 90-712 sends applications to the building official on city forms, with a fee set by city council resolution. Table 90-708-4 lists the temporary window sign (paper or fabric) as Permit Required: N, with a permitted duration of "No maximum" subject to footnote (f). Footnote (f) requires temporary window signs that are faded, yellowed, ripped, non-taut or otherwise damaged to be removed immediately.

Section 90-703 exempts two small window items from the permit requirement: incidental signs (two signs per business, two square feet in total) about credit card acceptance, restrooms or smoking, and "Help wanted" signs up to six square feet and four feet high. Businesses on the Form Based Code district frontages (Crescent Street, Michael Street south to Prairie Parkway, Division Avenue and new private or platted roads) follow a separate division. Its section 90-2014 requires surface applied window signs to be professionally painted or applied letters, corporate logos, symbols or designs, and bans neon channel signs.
