Plumbers in Minnesota can work under several distinct classifications, each of which requires its own license.

Whichever you want to get, a prospective plumber must make an application to the state, and provide a proof of sufficient experience per state guidelines.

They must then pass an exam and renew their license every two years.

Journeyman and Master Plumber is the two plumbing licenses available through the Minnesota Department of Labor and Industry.

Minnesota Plumbing License Reciprocity

It is good to hear that Minnesota has plumbing reciprocity agreements with North Dakota and South Dakota.

This means that licensed plumbers can apply for reciprocity without an exam if they hold a license of the same level or higher.

Their existing license must be current and must have been held for at least a year to be accepted.

Furthermore, it is necessary that they pay a $50 fee.

We consider it worth mentioning that there is a requirement that they must not previously fail a plumbing licensing examination in the state of Minnesota.

Minnesota Master Plumbing License Requirements

To become a master plumber in Minnesota, you need to be lawfully qualified to contract for plumbing and installations and to conduct the business of plumbing and be familiar with the laws and rules.

A master plumbing license is possible to achieve only if a person completes the set requirements.

He/she has to have five years of in-field experience which is added to at least one of the following: 

  • A journey worker plumbing license with the state
  • A restricted master plumbing license along with a plumbing code compliance bond, which has been on file with the state for at least 5 years
  • A license from another state which falls under Minnesotan plumbing reciprocity guidelines

They must submit an application to the state and a $50 application fee, and pass the appropriate exam.

Minnesota Plumbing Journeyworker License Requirements

In Minnesota, the term “journeyworker” is used in place of “journeyman.” But the definition is the same.

This is an individual who is engaged as an employee or is working under the direction of, a master plumber in the practical installation of plumbing.

If you want to get a journey worker plumbing license, you must complete the following requirements:

  • Provide proof of registration as an apprentice plumber
  • Provide proof of holding a current restricted journey worker license or restricted master license for at least two years
  • Provide proof of at least 7,000 hours of in-field experience over the course of four years
  • Provide proof of at least 2,000 hours in-field experience with water distribution system installation AND at least 2,000 hours in-field experience with drain, waste, and vent system installation AND at least 1,000 hours in-field experience with fixture installation
  • Submit an application form and a $50 fee
  • Take the appropriate exam

Plumbing Master and Journeyworker Exam

When you send the application for the exam you want to take and it is accepted, you can schedule the wanted exam at one of the designated examination sites and pay a $120 examination fee which is the same for both a master and journeyworker plumber exam.

The master plumber test has a greater focus on administrative issues and you can find several online resources to prepare you for the exam.

Minnesota Plumbing Apprenticeship Requirements

In Minnesota, plumbing apprentices are unlicensed plumbers.

To become an apprentice, work experience is not required.

You just need to pay a fee that is $14.

You can do all plumbing work as an apprentice, but it requires direct supervision under a licensed plumber.

During the training period, you must have 7000 hours of practical experience, and those hours are related to three categories: 2000 hours on water distribution system installation, 2000 hours on drain, waste, and vent system installation, and 1000 hours on fixture installation.

After four years of this training, you are eligible to take the journeyman exam.

You must renew your Minnesota plumbing license every two years by paying a fee of $128.

Plumbers need health and disability insurance.

Those who work in an organization will have employers who may handle these benefits, while an independent worker needs to purchase your own plan or get coverage through a union.

Plumbers need liability insurance in case of damage to a client’s property.

Should I Join a Union?

Many plumbers wonder whether joining a union will be helpful.

In the plumbing trade, the Plumbers and Gasfitters Union 34 has a five-year, paid apprenticeship program and journeyman test preparation.

Many plumbers depend on a local union as it helps them with health insurance and other benefits.

Unions are also beneficial as they negotiate work contracts at larger organizations.


A plumber’s pay rate highly depends on his or her license level and location, as well as experience.

At the starting level, a registered unlicensed plumber, which is an apprentice, will make about $15 per hour.

However, the average pay for a journeyman or master plumber in Minnesota is $30.82 per hour, meaning that their average salary is around $58,701.
