Full Breakdown

Sangamon County's zoning ordinance lists window signs among the sign types exempt from a zoning permit, alongside construction signs, directional signs, temporary signs, nameplates, and government notices. County Code Section 17.62.050 requires only that exempt signs still conform with the ordinance's other general provisions: maintenance, prohibited types, and district lighting rules. The county sets no separate percentage-of-glass or square-footage cap for window signs specifically. This section applies only in unincorporated Sangamon County; Springfield, Chatham, Rochester, Sherman, Riverton, Auburn, Pawnee and Divernon each administer their own sign codes inside their corporate limits.

Violations & Fines

No permit fee or zoning-administrator sticker is required for a window sign, but ignoring the ordinance's maintenance and prohibited-sign rules can still draw a citation from the county zoning administrator.
