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
The department coordinates plan approvals and inspections through completion and occupancy. Required building inspections include site setbacks, excavation, foundation/reinforcing, slab, framing, insulation, above-ceiling work, and final inspection before occupancy; contact 419-221-5243 or use the department's Franklin Information Systems services.
Minor-work playbook
Understand what may be exempt—and what is not.
The official process guide exempts detached storage sheds under 120 square feet, ground-level patios, residential cabinets, backyard recreational play equipment, gutters, and limited minor electrical repairs. HVAC replacement is exempt unless ductwork or system operation is modified.
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.
No verified planning reference link is listed; ask the agency for the parcel-specific source.
