Indiana Plumbing License: Everything You Need to Know

The plumbing industry in Indiana is expanding, providing a promising career path for skilled professionals. This guide covers all the essentials for obtaining your Indiana plumbing license, including license types, requirements, salaries, apprenticeship options, and renewal processes.

What plumbing work can be done without a license?

In Indiana, all professional plumbing work requires a license. Apprentices are the only exception, but they must work under the direct supervision of a licensed plumber.

What are the different types of plumbing licenses available in Indiana?

Indiana offers a structured path to becoming a licensed plumber through three main license levels:

• Apprentice Plumber License
  • Requirements:
    • Must be at least 17 years old to apply.
    • Complete a minimum of four years in a state-approved plumbing apprenticeship program.
    • Accumulate 576 hours of classroom training and 1,900 hours of fieldwork each year.
    • Submit an apprenticeship application with proof of training.

• Journeyman Plumber License
  • Requirements:
    • Complete a state-approved apprenticeship with at least 7,600 hours of training.
    • Pass the journeyman plumber exam administered by the Indiana Plumbing Commission.
    • Submit proof of experience and pay the $25 application fee.
  • Scope of Work: Journeymen follow state codes, test components, and install plumbing supplies for residential and commercial projects.

How to get a plumbing license in Indiana

Most licensed plumbers in Indiana begin their careers as apprentices. The Indiana Plumbing Commission is responsible for providing licenses to state plumbers. Before becoming a plumber, you must do an apprenticeship. 

The apprenticeship requires 576 hours of training in a school setting and 1,900 hours of fieldwork each year for 4 years. You also need to complete 7,600 hours of training in the field and on the job. Several technical schools in Indiana offer apprentice training, including AC/C Tech and Mechanical Skills, Inc.

Checklist for Obtaining a Plumbing License

To become a licensed plumber in Indiana, you’ll need to progress through three key licensing levels, each with specific experience and examination requirements. Here’s a breakdown of the steps and qualifications needed for each license:

1. Apprentice Plumber License
   • Be at least 17 years old and complete the application process.
   • Complete four years of school and fieldwork, totaling 7,600 hours of training.
2. Journeyman Plumber License
   • Complete the apprenticeship, pass the journeyman exam, and submit proof of experience.
3. Master Plumber License
   • Work as a journeyman plumber, pass the master exam, and apply with proof of experience.

Educational Costs

Your educational costs will depend on both the plumbing program and the school. Online programs often charge less than $1,000 per year but do not include any fieldwork opportunities. Career and vocational schools offer certificate programs that cost up to $3,000 per year. Most community colleges offer financing options, such as payment plans and loans.

Plumbing Exams

To get a journeyman license, you must pay a $25 application fee. You’ll also take an exam after completion of your fieldwork and apprenticeship. Contractors must take a similar exam that focuses on sewage and drainage systems for residential and commercial properties. The contractor license requires an application fee of between $50 and $100. Exams are available from the International Code Council (ICC) with online registration. The ICC website also offers free resources to help you prepare for the exams.

Criminal Background

A criminal background check is part of the licensing process. Though felons can apply for an Indiana plumbing license, it depends on the type of crime. For example, crimes against people may block someone from getting a license.

Should I join a union?

Joining a union can offer several benefits for Indiana plumbers:
