Codes, exemptions & field inspections
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.
Regulatory framework
2012 International Building, Existing Building, Fire, Mechanical, Fuel Gas, Property Maintenance, and Residential Codes; 2024 Illinois Energy Conservation Code effective November 30, 2025; 2014 Illinois Plumbing Code; 2011 NEC; applicable fire, accessibility, EV-charging, zoning, subdivision, and stormwater requirements.
Inspection lane
Call 309-558-3771 to schedule. Requests made after 10:00 AM are generally scheduled for the next business day. The general contractor is responsible for arranging the final inspection and occupancy approval.
Minor-work playbook
Subject to zoning approval and floodplain limitations: fences up to 6 feet; one-story accessory buildings up to 70 square feet in a floodplain or 120 square feet outside it; painting, papering, and similar finish work; prefabricated pools up to 18 inches deep; retaining walls up to 4 feet; and wall-supported residential awnings projecting up to 54 inches.
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.
Inspection pipeline
Request with lead time
Call 309-558-3771 to schedule. Requests made after 10:00 AM are generally scheduled for the next business day. The general contractor is responsible for arranging the final inspection and occupancy approval.
Preserve access
Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
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
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.

Field sequencing matters
Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.
When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.
Closeout file
Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
