Permit Requirements in Indianapolis, IN: What Residents Actually Need to Know

If you live in Indianapolis or are thinking about moving there, permit requirements are one of those things you probably won't think about until they affect you directly. Indianapolis has 4 specific rules on the books covering different aspects of permit requirements, and some of them might surprise you.

Deck & Patio Permits

Indianapolis requires a building permit for decks over 30 inches above grade or over 200 sq ft. Patios at grade do not need permits. Covered structures always need permits. Guardrails required on decks over 30 inches above grade.

Key details: Permit Threshold: >30" above grade or >200 sq ft. Patios at Grade: No permit needed. Covered Structures: Always need permit. Guardrails: Required over 30 inches.

Building without a permit: stop-work order and fines. May require retroactive permitting.

Shed & Outbuilding Permits

Indianapolis requires a building permit for sheds over 200 square feet. Sheds 200 sq ft or under are generally exempt if detached, single-story, and without utilities. Zoning setbacks apply to all sheds.

Key details: Permit Threshold: Over 200 sq ft. Under 200 sq ft: Exempt (no utilities). Location: Rear/side yard only. Portal: Accela Citizen Access.

Building without a required permit: stop-work order and potential fines. May require retroactive permitting or demolition.

Fence Permits

Indianapolis generally does not require permits for residential fences 6 feet or under. Fences over 6 feet require a building permit from BNS. All fences must comply with zoning setback and height requirements.

Key details: No Permit: 6 ft or under. Permit Required: Over 6 ft. Front Yard: 4 ft max. Pool Fence: Min 48 inches.

Non-compliant fences: notice of violation. May be required to modify or remove.

Indianapolis is more permissive than most cities when it comes to fence permits. That said, there are still limits.

Renovation Permits

The Indianapolis Department of Business and Neighborhood Services (DBNS) issues all residential renovation permits in Marion County. Kitchen and bathroom remodels almost always need a plumbing permit (any drain/supply line change), an electrical permit (any new circuits or service changes), and a mechanical permit for HVAC or kitchen exhaust changes. A separate Structural Permit is required for any load-bearing wall removal, additions, or change of use.

Key details: Permit Agency: Indianapolis DBNS. Code Adopted: Indiana Residential Code (2020 IRC) per 675 IAC 14-4.4. Plumbing Permit: Required for drain/supply/fixture relocations. Electrical Permit: Required for new circuits, panel/service changes. Structural Permit: Required for load-bearing changes, additions, conversions.

Doing renovation work in Indianapolis without required permits is a violation of the consolidated Marion County Building Code. DBNS may issue a stop-work order, require after-the-fact permitting (at significantly higher fees), and require exposing concealed work for inspection. Unresolved violations are cited to the Marion County Hearing Officer and can result in liens on the property under IC 36-7-9.

The Bottom Line

Indianapolis's permit requirements rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Indianapolis is broadly strict or permissive.
