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
For unincorporated Peoria County, the published current-code sheet lists the 2018 International Building, Residential, Existing Building, Mechanical, Fuel Gas, and Fire Codes; 2021 Illinois Energy Conservation Code; 2017 National Electrical Code; 2018 Illinois Accessibility Code; and the current Illinois Plumbing Code, Part 890.
Inspection lane
All permits require inspection, with the number and type varying by project. Use the county Building Inspections guidance or call 309-672-6915; digital submittal questions may be sent to buildingpermits@peoriacounty.org.
Minor-work playbook
The county FAQ says permits are required for sheds over 200 square feet and decks over 25 square feet; smaller examples may not require a building permit, but applicants should confirm with Planning & Zoning. Pools, fences, demolitions, new homes, additions, repairs, and applicable electrical, HVAC, and plumbing work require permits.
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
All permits require inspection, with the number and type varying by project. Use the county Building Inspections guidance or call 309-672-6915; digital submittal questions may be sent to buildingpermits@peoriacounty.org.
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.

Project questions
Peoria County Planning & Zoning / Building Inspections is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 309-672-6915.
Once a complete, code-compliant submittal is received, residential review usually takes 2-3 business days and commercial review averages 14 business days; some permits can be issued the same day without plan review.

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.
