Mount Prospect, IL Sign Regulations: Political Signs (2026)

Section 7.202 exempts certain signs from the general provisions of the Mount Prospect sign chapter and from its permit requirements. Subsection D, Noncommercial Temporary, closes with a list of examples that names political signs next to park district, school or church events, proud union home signs and holiday decorations. Political signs are therefore measured by the rule printed for that group, not by a separate election-sign rule.

On single-family residential properties, the total area of all such signs on a lot cannot exceed sixteen square feet. The signs are allowed for a period not to exceed ninety days, and they are removed within three days after the conclusion of a special event, except as otherwise required by state or federal law. A sign that does not meet the temporal requirements of the subsection requires a permit.

On other properties the tests are per sign. Each sign cannot exceed sixteen square feet in area or six feet in height from the finished floor elevation of any relevant space, and no more than one sign is allowed per street frontage. The sign must be located on private property and cannot be attached to any parking light pole or tree, and multi-tenant properties must attach the sign to the wall of their establishment. It comes down within three days after it no longer meets its intended purpose, and in any event stays up no longer than ninety days.

Other rules in the chapter still bite. Section 7.201 prohibits signs on light poles and any sign located in or extending over the public right of way unless the Village Board authorizes it, so a yard sign cannot go in the parkway.
