Codes, exemptions & field inspections
Build to the adopted code. Verify every exception.
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Inspection lane
Building Safety staff review plans, issue permits, and perform inspections. For construction and inspection questions, call 217-753-6760; the county advises contacting the appropriate municipality first for zoning requirements, and the county has IGAs with listed municipalities.
Minor-work playbook
Understand what may be exempt—and what is not.
The fee schedule identifies ag-exempt permits for Category 1 agricultural storage facilities, although electrical, plumbing, and HVAC permits may still be required. Possible waivers include qualifying owner-occupied hardship residences, natural-disaster or total-loss-fire projects, unoccupied government accessory structures, and construction supporting a disabled veteran's disability; eligibility is subject to the stated conditions and administrator or statutory approval.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.

Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Verify the builder before the contract is signed.
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
Keep the parcel rules beside the building plans.
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.
