Project questions
Frequently asked questions for Hamilton County
Who handles permitting for this jurisdiction?
Hamilton County Plan Commission is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
How should I begin an application?
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 317-776-8490.
How long might review take?
A typical review timeline was not verified. Ask the agency for its current completeness and review estimate.
How are inspections scheduled?
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.
Which codes and exemptions should I review?
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. 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.
