If you're planning to work as a plumber in Indiana, you will need a state-issued license. The Indiana Plumbing Commission sets the rules for all plumbers, from apprentices just starting out to experienced contractors running their own businesses. This guide walks you through the exact requirements, application steps, and fees for obtaining your Journeyman Plumber or Plumbing Contractor license in Indiana.

Do You Need a Plumbing License in Indiana?

Yes, the Indiana Plumbing Commission requires a state-issued license to perform any plumbing work in Indiana. This statewide requirement is mandated by Indiana Code (IC) 25-28.5, and the commission, administered by the Indiana Professional Licensing Agency (PLA), is responsible for issuing all plumbing licenses.

Working without the proper license can lead to significant penalties, including fines and legal action. It is crucial to obtain the correct license before starting any plumbing work.

Types of Indiana Plumbing Licenses

Indiana has two primary license classifications, Journeyman Plumber and Plumbing Contractor, as well as a path for apprentices.

Journeyman Plumber License

A Journeyman Plumber is licensed to perform plumbing work under the direction of a licensed Plumbing Contractor. This license certifies that the holder has the required training, experience, and technical knowledge to install and repair plumbing systems according to state codes.

Plumbing Contractor License

A Plumbing Contractor is licensed to operate a plumbing business in Indiana. This license allows the holder to contract directly with the public, bid on plumbing projects, and employ Journeyman Plumbers and registered apprentices.

Plumbing Apprentice (Registration)

An apprentice is an individual learning the trade through an approved program while working under the supervision of a licensed plumber. This is not a license but a required registration for those on the path to becoming a Journeyman.

How to Get an Indiana Journeyman Plumber License

  • Experience Path 2 (Out-of-State Licensee): If you are licensed in another state, you may qualify by documenting four (4) years of experience in the plumbing trade. This must be verified by a copy of your current, active plumbing license and a signed employer affidavit detailing your experience.
