About each permit
Certificate of Zoning Compliance
Zoning Code §40-11-2 provides that no new use or structure may be established, and no existing use or structure enlarged, altered or put into operation, until a certificate of zoning compliance has been issued. Under §40-1-3 the Zoning Code applies to all unzoned municipalities and to all unincorporated properties in St. Clair County except those occupied by Scott Air Force Base. The Zoning Code's Schedule of Filing Fees (Ord. No. 18-1203) sets the application at $30, and the Building & Zoning Department page states "EFFECTIVE JANUARY 2020 ZONING COMPLIANCE LETTERS WILL HAVE A FEE OF $30.00." The department's Building Permits page lists the completed Application for Certificate of Zoning Compliance, with its $30 fee, among the items needed for a building permit. Initial certificates are valid for one year and may be renewed for successive one-year periods (§40-11-3).
Commercial Building Permit
The Building & Zoning Department issues building permits for commercial and industrial construction in unincorporated St. Clair County and, under contract, in East Carondelet, Fayetteville, Freeburg, Lenzburg, Marissa, Millstadt, New Athens and St. Libory. The department's Building Permits page states that a commercial or industrial permit requires one set of plans and specifications designed by an architect licensed and registered in the State of Illinois, with the seal on every sheet, and that a permit is invalid 12 months after it is issued, with one extension of up to 180 days. The fee for commercial and industrial construction is set by County Code §7-1-50 according to the estimated cost of construction, and the department's page directs applicants to Chapter 7 for the commercial and industrial fee schedule; contact the Building & Zoning Department at (618) 825-2528 for the amount for a given project. A business inside any other city or village applies to that municipality instead.
