In Marion County, Indiana, plumbing permit requirements are generally handled by the county-level building and safety divisions.

Generally, any construction activity related to a plumbing system requires a permit in Indianapolis (which is consolidated with Marion County). There are, however, several exceptions. Permits are not typically required for the "replacement in kind" of piping, as long as the replacement piping meets the same specifications and capacity as the original, and no more than 20% of the total piping in the structure is replaced. Additionally, replacing appliances, fixtures, traps, and valves, or replacing a water heater with an identical model, usually does not require a permit. Initial connections or reconnections of plumbing to a mobile home not on a permanent foundation and located in a licensed mobile home park are also exempt.
For specific requirements and to apply for permits, it is recommended to consult the relevant county or city building department. Some resources indicate that for unincorporated areas of Marion County, the Building Inspection Division reviews plans and issues permits. For incorporated cities that contract with Marion County, the specific city's building department or plan commission would be the point of contact.
Rules for Properties in Unincorporated Areas
Marion County has direct responsibility for issuing all permits in the unincorporated areas of the county. This means that for plumbing work on properties not within an incorporated city's limits, you will need to go through the Marion County Building Inspection Division or a similar county-level authority. This division reviews construction and remodeling plans for these areas and enforces building codes.

State Statutes and Plumbing Codes in Indiana
Plumbing regulations in Indiana are established through a combination of state statutes and administrative rules. The primary regulatory framework for plumbing installations is found in the Indiana Administrative Code (IAC), specifically under Title 675, which is managed by the Fire Prevention and Building Safety Commission. These rules adopt national model codes as a base, which are then modified by Indiana-specific amendments to address local requirements and standards.
It is important to note that while the state sets minimum standards, local jurisdictions may have additional requirements or stricter ordinances. Furthermore, the licensing of plumbing professionals—including contractors and journeymen—is governed by Indiana Code (IC) Title 25, Article 28.5, and is administered by the Indiana Plumbing Commission.
Primary State Agencies
- Fire Prevention and Building Safety Commission: This body is responsible for the adoption and maintenance of the state's building and plumbing codes (found in 675 IAC). They oversee the technical standards for construction and installation.
- Indiana Plumbing Commission: Operating under the Indiana Professional Licensing Agency (IPLA), this commission is responsible for the regulation, examination, and licensing of plumbing professionals in the state.
