If you want to start a steady career in plumbing, Minnesota has several good training options. In this trade, skills matter more than degrees. You'll need hands-on training, classroom instruction, and a state license if you want to work legally.

Here's how to get started and where to train.

Minnesota Plumbing License Requirements

In Minnesota, plumbers must be licensed by the Minnesota Department of Labor and Industry (DLI). To start as a licensed plumber, you'll need to first work as an apprentice under a licensed journeyman.

Minnesota Rule: "All individuals performing plumbing work in Minnesota must be licensed or registered with the DLI." 1

Basic licensing steps:

  1. Register as a plumber's apprentice with the DLI.
  2. Complete the required on-the-job training hours under a licensed plumber.
  3. Complete related technical instruction (usually at an approved school).
  4. Apply for the journeyman plumber exam and pass it.

How Long Does Plumbing Training Take?

Most aspiring plumbers in Minnesota spend 4-5 years in an apprenticeship program. School training can range from a few months to two years, depending on the program type.

Program Type Typical Length Includes Hands-On Training?
Certificate 6-12 months Yes
Diploma 1-2 years Yes
Apprenticeship 4-5 years Yes, OJT + classroom
