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
The Hamilton County Plan Commission applies the Hamilton County Unified Development Ordinance, amended July 10, 2023, together with applicable Indiana building requirements; the current public page does not identify a specific 2026 state-code edition.
Inspection lane
Submit an electronic permit application through the Plan Commission page and contact the office at 317-776-8490 for required inspections or special-use building appointments. The county contains nine planning jurisdictions, so confirm that the project lies in the Hamilton County Plan Commission area rather than a municipal planning area.
Minor-work playbook
Within the Hamilton County Plan Commission jurisdictional area, no building permit is required for replacement of windows or doors, interior decorating, exterior painting, or replacement of roof shingles. Normal maintenance and repairs such as roofing, flooring, plumbing/heating repairs, insulation, and minor opening replacements are also listed as fee/permit-exempt. Farm structures still require a special agricultural accessory permit, although detailed construction plans may not be required.
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
Submit an electronic permit application through the Plan Commission page and contact the office at 317-776-8490 for required inspections or special-use building appointments. The county contains nine planning jurisdictions, so confirm that the project lies in the Hamilton County Plan Commission area rather than a municipal planning area.
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.

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.
