How to Become a Plumber in Illinois


Becoming a plumber can be a very rewarding career path for many people. It is an honorable profession and one that stays in demand year-round.

The path to becoming a licensed plumber is not very difficult, provided you are prepared to put in the work. You need to complete an apprenticeship with a licensed plumber before you can get certified yourself.

There are different requirements for becoming a plumber in different states. Read on to find out everything you need to know about becoming a plumber in Illinois.

Qualifications for Becoming a Plumber in Illinois

There are 3 different kinds of plumbing licenses you can apply for. They are, in order of seniority, the apprentice license, plumber license, and contractor license.

There is currently no reciprocity of plumbing licenses in Illinois with other states, so plumbers certified in other states will need to get certified by the Department of Public Health in Illinois if they wish to ply their trade in Illinois.

The only exception is for Chicago plumbers—they can submit an application for reciprocity in Illinois and they won’t need to go through the certification process in Illinois. It costs $150 to submit the application.

Here are the basic requirements for each level of plumbing certification in Illinois:

Plumbing Apprenticeship Requirements

An apprenticeship program is the first step towards becoming a certified plumber. Being an apprentice means that you are learning the skills required to become a plumber by working under a licensed plumbing professional.

You cannot be an apprentice for more than 6 years. A licensed plumber needs to sponsor you for you to be eligible for an apprenticeship. If you have a plumber’s sponsorship and fulfill the following requirements, you can start your plumbing apprenticeship:

  • Be 16 years of age or older
  • Have sponsorship proof
  • Filled out the apprentice plumber licensing form
  • Pay the $100 fee through money order or check

After completing your apprenticeship, you can sit for the licensing exam to become a licensed plumber. You need to give the exam within 6 years of starting your apprenticeship, otherwise, your apprenticeship will be revoked.

Plumbing License Requirements

Most states in America have a journeyman’s license and master certifications for plumbers, but Illinois does not offer any such certification. Once an apprentice meets the following requirements, they can obtain a plumbing license:

  • Be a citizen of the United States or be in the process of becoming one
  • Have at least 4 years of experience working as an apprentice
  • Possess proof of their apprenticeship
  • Have finished a minimum of 2 years of high school or hold equivalent qualifications
  • Have attended an accredited plumbing course at a trade school, college or university
  • Filled out the application for the plumber’s license examination
  • Paid the $175 application fee

According to the Department of Public Health, you only need 4 years of experience as an apprentice to be eligible for the plumber licensing exam.

However, if you are part of a union, you need at least 5 years of apprenticeship experience. Apprentices also need to complete over 1,200 classroom hours according to union laws in Illinois.

Illinois residents pay a $175 fee, but if you reside outside of Illinois, the application will cost you $225.

Chicago is the only state with a plumbing license reciprocity in Illinois. Since the journeyman certification is acceptable in Chicago, licensed journeyman plumbers can work here.

Plumbing Contractor Requirements

Plumbing contractors are plumbers qualified to work more complex plumbing jobs. They can install or construct water systems, act as consultants for planning structural changes in the plumbing system and supervise plumbers.

They usually have many licensed plumbers and apprentices working for them. If you plan on establishing a plumbing company or wish to enter into a partnership with other plumbers, you need a contractor’s license.

The following requirements are necessary for obtaining a plumbing contractor’s license in Illinois:

  • Be a licensed plumber
  • Fill out the registration application for plumbing contractors
  • Pay the $150 application fee

Retired Plumbing License

Plumbers who want to retire from the trade can acquire a retired plumbing license. Having a retired plumbing license means that you are still state-certified and considered competent for plumbing jobs.

If you ever want to renew your plumber’s license to reinstate yourself as a plumber, you will be able to do so at a reduced cost. It makes a lot more sense to get a retired plumbing license than to renew an expired plumbing license.

It is important to note that retired plumbing licenses are only proof of competence, it does not mean that you can sponsor apprentice plumbers or supervise plumbing jobs.

Individuals who are 62 years of age or older or those physically unable to work as a plumber can apply for a retired plumbing license. You will be asked to surrender your plumber’s license to obtain a retired plumbing license.

License Renewal

Plumber licenses are not valid indefinitely. They need to be renewed every year by the Illinois Department of Public Health.

April 30th of every year is the last date to renew plumbing licenses. The good news is that the renewal of licenses can be done online, which saves everyone a lot of trouble.

Plumbers must keep in mind that they are required to state whether they have defaulted on child support payments or not—even if they don’t have any children. This information is mandatory for the license renewal application.
