St. Clair County, IL Code Violation Reporting: How to Report (2026)

Any resident who believes a property in unincorporated St. Clair County violates the Zoning Code files a written complaint with the Zoning Administrator under Sec. 40-11-8. The Administrator must record the complaint, investigate promptly, and institute appropriate corrective action if a violation is confirmed. If the Administrator finds a violation by inspection or complaint, Sec. 40-11-5 requires a written Corrective Action Order naming the premises, describing the violation, stating the remedial action and deadline to correct it, and giving the alleged violator the right to a conference with the Administrator and a stated deadline and procedure to appeal.

Section 40-11-6 requires the order be served personally, by certified mail to the last known address, or posted conspicuously on the property. Where the Administrator determines a violation poses an imminent peril to life or property, Sec. 40-11-7 lets the Administrator act immediately without notice or hearing to alleviate the condition. Ignoring a corrective action order risks revocation of any Certificate of Zoning Compliance on the property and the fines set out in Sec. 40-11-10. The County Board sets filing fees for permits and procedures under this Code by resolution (Sec.

40-11-9); those fees fund administrative costs, are paid to the County Treasurer, and are non-refundable. Complaints and corrective action orders under this Division apply to unincorporated county territory only; Belleville, East St. Louis, O'Fallon, Fairview Heights, Swansea, Cahokia Heights, and Mascoutah enforce their own municipal codes.
