Inspection lane
Contact building@johnsoncounty.in.gov or 317-346-4350 for permit assistance and inspections.
Minor-work playbook
Understand what may be exempt—and what is not.
The public county pages do not publish a complete minor/cosmetic exemption list; properties inside municipalities are outside county jurisdiction and should use the municipal authority.
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.
