How Plumbing licensing works in Indiana
In Indiana, plumbing is a licensed trade. That means you can’t legally work as a plumber without meeting the state’s requirements.
According to the Indiana Professional Licensing Agency, plumbers must first complete an approved apprenticeship before applying for a journeyman or plumbing contractor license.
Here are the basic steps:
Apply for an apprenticeship with a union, trade school, or employer that offers a state-approved program.
Complete at least four years of combined classroom and on-the-job training.
Pass the state exam for journeyman or plumbing contractor, depending on your career goal.
Maintain your license by following renewal and continuing education rules.
Plumbing training in Indiana generally fits into one of these categories:
Union apprenticeships Offered through local plumbers’ unions and include paid on-the-job training.
Trade school. Programs Classroom-based with some lab work, often followed by an apprenticeship.

Each route gives you the skills you need to handle residential, commercial, and industrial plumbing systems.
