Full Breakdown
St. Clair County's sign regulations (Article VII, Ch. 40) do not name political or campaign signs. Such signs are treated as a "Temporary Sign": an advertising device or display "intended for a temporary period of display; such as decorative displays for holidays or public demonstrations" (Sec. 40-7-3(I)). Maximum temporary sign area is 48 sq ft, and "Temporary signs shall not remain in place for a period of more than thirty (30) days," extendable once by the zoning official. General sign rules (Sec. 40-7-2) bar placement within 10 feet of any lot line and in public right-of-way. These county rules apply to unincorporated land only; municipalities regulate signs within their limits.
Violations & Fines
Signs exceeding the size or time limits or placed in the setback/right-of-way violate Article VII and can be ordered removed with penalties.
