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
Where Lee County has no separate building code, plan review uses the most current International Building Code or International Existing Building Code, the Illinois Energy Efficient Building Code or Illinois Stretch Energy Code, Illinois Accessibility Code, Illinois Plumbing Code, applicable fire rules, and the most current National Electrical Code.
Inspection lane
Contact Building Official Joe Bay at 815-288-3109 or jbay@countyoflee.org for inspection arrangements. Commercial structures must obtain required inspections and approvals before permit approval; commercial inspection certificates are obtained through Casper's Home Inspections at 815-440-2146. Do not begin after online submission alone: only an approved placard and approval letter authorize work.
Minor-work playbook
The county does not publish a broad cosmetic exemption list on its current permit page. Fences and pools use separate applications; qualifying agricultural structures may receive special treatment under applicable law, but applicants must confirm requirements with the office. Government agencies still must submit an application even when no fee is charged.
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
Contact Building Official Joe Bay at 815-288-3109 or jbay@countyoflee.org for inspection arrangements. Commercial structures must obtain required inspections and approvals before permit approval; commercial inspection certificates are obtained through Casper's Home Inspections at 815-440-2146. Do not begin after online submission alone: only an approved placard and approval letter authorize work.
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.
Open planning reference ↗Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
Lee County Building and Zoning Office 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 815-288-3109 (Building Official); 815-288-3643 (Building and Zoning Office).
The county states applicants are contacted within 1-3 business days after online submission; complete commercial plans are subject to plan review and may require third-party 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.
