Do You Need a Permit?

The DBNS Fee Schedule - Permits (as of January 5, 2026) prices structural permits by type and area. "Remodeling, alteration, or repair of Class 2 structures; no addition" is $40 + $150 review + $200 issuance = $390 up to 1,000 square feet. A misc. residential permit is $40 + $100 + $150 = $290. An accessory structure is $40 + $150 + $300; an addition to the house $40 + $150 + $400.

Trade permits are separate: plumbing repair or alteration $153 up to 1,000 square feet, electrical repair or addition $169, heating or cooling $153, combined heating and cooling $185. The electrical section also has its own heating and cooling equipment line ($146, or $178 combined).

The City's paid-fee records settle how common jobs are billed. A deck takes a structural permit at $40 + $150 + $150 plus a $140 Improvement Location Permit, $480 in all. A like-for-like AC replacement takes one heating and cooling permit at the $89 general service fee, with no electrical permit. A kitchen or bath remodel takes the $390 structural alteration permit even with no load-bearing change, plus plumbing and electrical permits: $712. Rooftop solar takes electrical, structural and Improvement Location permits: $699.

You need a permit in Indianapolis for most structural changes and trade work. But the exemption list is longer than many cities. Like for like window and door replacement in the exact same opening skips the permit when a listed contractor does it. Same deal for roof replacement if there's no configuration change, no added dead load, no structural work beyond limited decking and no heat applied material. Worth the detour. Siding over existing sheathing gets exempted too. Sheds 120 square feet or smaller with no foundation or utilities don't need approval. Fences that meet zoning rules are also exempt. You don't need a permit in Indianapolis to replace a water heater if it matches the original venting and fuel type exactly. But a bathroom remodel that moves fixtures or adds electrical will trigger the full set of permits. The Department of Business and Neighborhood Services enforces this through Chapter 536 of the Indianapolis Revised Code. Work begun without an Improvement Location Permit carries a $250 first-offense fee in the city's code enforcement schedule. Check the Homeowner's Building Permit Guide before you tear anything open.

Indianapolis doesn't publish specific doubled fee penalties in the main schedule I reviewed. But they follow standard enforcement under the Indiana Residential Code and local Chapter 536. Unpermitted work often triggers retroactive permits plus fines. Code enforcement usually learns about violations from neighbor complaints or when you try to sell the house. Nobody wants that headache. The city can issue stop work orders and require removal of unpermitted changes. They won't hesitate. Better to pull the permit upfront than explain yourself later.

Indianapolis permits don't expire on a fixed schedule listed in the fee workbook. Work must generally begin within six months and stay active. Check with DBNS for your exact project type. They can revoke inactive permits. Renewals happen through the same department. Don't assume your approval lasts forever.

Contractors usually pull permits in Indianapolis. They carry the license and insurance. Homeowners can pull their own permits for work on their primary residence but they accept full responsibility for code compliance. Most contractors I talk to won't work on a job where the homeowner pulls the permit. It creates liability issues. Read your contract carefully. If a contractor asks you to pull the Indianapolis building permit yourself that's a red flag. Walk away.

Indianapolis prices permits by work area, not construction value. A structural alteration of up to 1,000 square feet is $390 whether the job costs $8,000 or $50,000; larger areas add $25 review and $50 issuance per additional 500 square feet.

The exemption list in Chapter 536 of the Revised Code is long: listed contractors can replace a roof, windows or siding like for like without a permit, an identical water heater needs none, and fixture and cabinet installation and non-load-bearing walls need no structural permit (trade permits still apply). The DBNS fee schedule lists no state surcharge.

How much does a building permit cost in Indianapolis?

A structural alteration permit is $390 for work areas up to 1,000 square feet ($40 application, $150 review, $200 issuance). Plumbing is $153 and electrical $169. The City's own records show kitchen and bath remodels filed with the structural permit even with no load-bearing change, so a remodel with plumbing and electrical work comes to $712.

Do I need a permit to replace a water heater in Indianapolis?

No if it's an identical swap with the same venting arrangement and fuel type. The rules under section 536-201 allow this exemption. Anything different requires a $153 plumbing permit.

Do I need a permit in Indianapolis to build a deck?

Yes for decks more than 30 inches above grade. The City bills a deck on a structural permit at $340 ($40 + $150 + $150) plus a $140 Improvement Location Permit, $480 in all.

Do I need a permit in Indianapolis to replace a roof?

Not if a listed contractor follows the exact conditions in section 536-216. No configuration change, no added dead load and no heat applied materials keeps it exempt. Otherwise the structural permit is $390.

How much is a plumbing permit in Indianapolis?

A standard plumbing trade permit costs $153. That covers most bathroom and kitchen fixture work. The fee stays flat regardless of project valuation.

Why does Indianapolis charge the same permit fee for a $8,000 bathroom and a $50,000 kitchen remodel?

The city bases fees on the square footage of the work area, not project value. Any structural alteration up to 1,000 square feet is $390, so the finishes do not change the fee.
