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
N/A for a current 2026 code edition. The official county permit information states that permits are approved by the County Engineer; applicable Illinois state and local requirements also govern.
Inspection lane
The official permit form does not publish an inspection-booking procedure. Permits are submitted to the Supervisor of Assessments Office and approved by the County Engineer; contact 618-435-9800 for current instructions.
Minor-work playbook
The official county permit sheet requires permits for permanent structures, additions, mobile/manufactured homes, and permanently affixed decks or porches. Portable buildings, portable carports, and other portable structures smaller than 12 by 14 feet do not require a permit. A separate permit is required for each structure.
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
The official permit form does not publish an inspection-booking procedure. Permits are submitted to the Supervisor of Assessments Office and approved by the County Engineer; contact 618-435-9800 for current instructions.
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.
No verified planning reference link is listed; ask the agency for the parcel-specific source.
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
Franklin County Supervisor of Assessments Office / County Engineer is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
No verified online portal was located in the reviewed public materials. Contact 618-435-9800 and request the current application route before preparing a final submittal.
A typical review timeline was not verified. Ask the agency for its current completeness and review estimate.

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.
