Yes. Inside the City of Indianapolis, the Department of Business and Neighborhood Services requires a permit for any construction activity related to a plumbing system. Replacing pipe in kind is exempt only up to 20 percent of all the piping in the structure, so a whole-house repipe and most partial repipes need a permit, a rough-in inspection before the walls close, and a final.
Circle City Repipe offers whole-house and partial repipes across Indianapolis and nearby communities. In Indianapolis, that plumbing work is permitted through a state-licensed plumbing contractor registered with the City, and the work is carried out by licensed and insured contractors. This guide covers the rule, the fee, the inspections and how the permit offices around the city differ. The whole-house repiping page covers the job itself.
What the City requires
The Department of Business and Neighborhood Services (DBNS) puts it plainly: any construction activity related to a plumbing system requires a permit. The exceptions are narrow. Replacing fixtures, traps, valves and appliances is exempt, as is a like-for-like water heater. Replacing piping in kind is exempt only when it is no more than 20 percent of all piping in the structure.
Applications go through the City’s Accela Citizens Access portal with the Plumbing Permit Application. The form asks which code the work follows, the Indiana Plumbing Code or the Indiana Residential Code. Statewide, the plumbing code is 675 IAC 16-1.4, the 2012 Indiana Plumbing Code, built on the 2012 International Plumbing Code with Indiana amendments. Its water supply and distribution chapter governs the materials, sizing, valves and testing of a repipe.
Where the 20 percent exemption stops
The exemption exists so that a leak repair does not need paperwork. A pinhole repair, a split section after a freeze or a new length of pipe under one sink replaces a few feet out of hundreds. A whole-house repipe replaces all of it, so it is far past the limit. A partial repipe of one bath group or one floor usually passes it too.
How a particular partial job counts against the limit, and whether a change of material is still “in kind”, is a judgment for DBNS rather than for the person doing the work. When a job sits near the line, it is cheaper to ask before work starts than to find out at a sale or an insurance claim. Homeowners report contractors calling unpermitted work “basic plumbing”; the City’s wording is the test, not the contractor’s.
What the permit costs
DBNS publishes its fees on the City’s license and permit fees page. For a repair, alteration or remodel of an existing home, the fee is set by floor area.
| Where and what | Fee |
|---|---|
| Existing home, up to 1,000 sq ft | $153 |
| Each additional 500 sq ft | $23 |
| Worked examples at 1,500 / 2,000 / 2,500 / 3,000 sq ft | about $176 / $199 / $222 / $245 |
| Multifamily or commercial, up to 10 fixtures | $182, plus $23 for each additional 5 fixtures |
| Reinspection after a failed inspection | $175 |
The worked examples assume whole 500 sq ft steps; DBNS does not state how a partial step is rounded. The permit is a small part of a repipe price. The Indianapolis repipe cost guide shows where it sits among labor, material and patching.
What the inspector checks, and when
The City’s Building Standards require a separate rough-in inspection for plumbing work after installation, but before the pipe is covered or concealed and before fixtures are set. That rule sets the order of every permitted repipe: open the walls, run the pipe, pressure test it, pass the rough-in, then patch and set fixtures. A final inspection closes the permit.
An inspection checks the work against the code at the points the inspector sees: materials, support, valves, connections and the test. It does not judge how neatly the walls were cut or patched. Homeowners report that inspectors see less of a crawlspace than the plumber does, which is one more reason to ask for photos of concealed runs before they are closed. The repiping timeline guide covers how the inspection fits the schedule.

Who can pull the permit
In Indianapolis, plumbing contractors are licensed by the State of Indiana through the Plumbing Commission, and the City requires that license to be registered with it. The registration fee for a business entity is $142. A registered plumbing contractor may obtain a permit for the work that state licensure covers.
Owners are a separate case. State law, IC 25-28.5-1-32, says the plumbing licensing chapter does not apply to the owner occupant of a dwelling of eight or fewer units working on its own plumbing system. The City’s Building Standards let an owner-occupant obtain a permit for work on their own parcel, except work for which state law requires a license. Read together, those rules may let an owner-occupant pull their own permit, but whether DBNS issues it, and on what terms, is worth confirming before any pipe is cut. Homeowners report difficulty finding a plumber willing to pull a permit for work they do themselves, because the permit holder answers for the work.
The service line is a different permit
A repipe starts at the main shutoff inside the house. The buried service line from the street is Citizens Energy Group’s territory for permitting: any modification or replacement needs a Citizens permit, filed by a plumber with an active Citizens bond, and Citizens says the permit takes about 2 to 3 business days after a completed application. A full replacement must be SDR9 polyethylene with tracing wire. The service line and meter pit guide and the Citizens lead service line program guide cover that work.
In the historic districts administered by the Indianapolis Historic Preservation Commission, a permit exemption does not remove a possible need for a certificate of appropriateness. Exterior work such as a new meter pit or wall penetration may need one, confirmed per project.
Outside the City of Indianapolis
Four excluded cities inside Marion County keep their own municipal functions, and DBNS licensing does not cover them. The suburbs have their own building departments.
| Where the house is | Who issues the permit | What is known |
|---|---|---|
| Lawrence | Department of Public Works | A permit is required to install, alter, repair or replace any plumbing system; homeowners may obtain permits in certain circumstances; a hired contractor must be registered with Lawrence. Fee confirmed per address |
| Beech Grove | Clerk-Treasurer’s office, with the Building Commissioner | Plumbing contractors file a certificate of insurance naming the City and a bond. Fee confirmed per address |
| Speedway and Southport | The town or city | Confirmed per address |
| Carmel | Building Safety, Department of Community Services | One permit typically covers a project; plumbing is a listed inspection, and the rough-in must be approved before insulation. Whether a repipe alone needs a remodel permit is confirmed per project |
| Greenwood | Community Development Services | $75 for a residential plumbing permit; any combination of trade permits capped at $225; a plumbing plan is required |
| Westfield | Building Division | Rough-in is one of the listed residential inspections; whether a repipe alone is permitted as plumbing is confirmed per project |
| Brownsburg | Development Services | A permit is required for repairs to plumbing systems; inspections are requested two business days ahead |
| Avon, Fishers, Noblesville, Zionsville | The town or city building department | Confirmed per address |
Who issues the permit is set by the address, not the mailing city. The Lawrence, Beech Grove, Speedway, Carmel and Greenwood pages cover each one in more depth.
Why the permit is worth having
A permit gives the job an independent check at the moment it matters, before the pipe disappears behind the walls. It also leaves a record. A buyer’s inspector, an appraiser or an insurer may ask whether the plumbing was permitted, and a closed permit with a passed final answers that.
