Do you need a license to do plumbing in Michigan?
Yes, you must hold a plumbing license to perform any plumbing work in Michigan. Licenses are issued by the Michigan Department of Licensing and Regulatory Affairs (LARA).
Earning your license allows you to legally perform plumbing work, such as installing or repairing plumbing fixtures, replacing pipe systems, and cleaning drains. With a license, plumbers can work on both residential and commercial projects.
You’ll need to start the licensing process with a plumbing apprenticeship. As you continue to earn experience, you can apply for higher-level licenses that allow you to do more types of work with less supervision until you have your master plumbing license. To run your own plumbing business, you’ll need to get your Michigan plumbing contractor license.
Types of plumbing licenses in Michigan
Michigan offers three types of plumbing licenses that vary in the type of work you’re allowed to do:
- Apprentice: able to perform limited duties under the supervision of a journeyman or master plumber
- Journeyman: an entry-level license that allows individuals to work independently under the supervision of a master
- Master: highest license level that allows individuals to supervise journeymen, pull permits for projects, or run their plumbing businesses
Applicants must first register as an apprentice to start earning experience.
Michigan plumbing license requirements

How do I get a Michigan plumbing license?
It takes around three years to earn a journeyman license and five years to earn a master license. The plumbing license application process varies depending on the path plumbers take to meet the experience requirement. The process is as follows:

- Gain the necessary experience: Applicants must complete three years of work experience as an apprentice to be eligible for the journeyman license. To qualify for a master license, applicants must have completed two years of work as a licensed journeyman. For a contractor license, applicants must hold a master plumbing license.

You can also complete the application forms online through the LARA portal.

Requirements for business owners
If you’re looking to start a plumbing business, you’ll need to take a few additional steps beyond receiving your license. Only those with a master license can operate a plumbing business.
When starting a business, you’ll first need to establish the structure in which you’ll operate. You can choose from business structures such as an LLC, sole proprietorship, or partnership. Once you decide on your business structure, you’ll need to choose a name and register your business with your local government.
You’ll need to meet the following requirements to start your business:
- Get the necessary insurance: Business owners must obtain general liability, worker’s compensation, and commercial automobile insurance. In Michigan, business owners must maintain at least $300,000 in property damage insurance and $100,000 in general liability insurance.
- Obtain the necessary permits: The specific permits you need will depend on the local jurisdiction of the location where the project will take place. Check with your local Building and Codes office to determine the specific permits you’ll need.
On average, it costs around $10,000 to get all the tools, equipment, and insurance needed to start a plumbing business. If needed, you can apply for a small business loan to help cover the initial costs. You can also check with your local government to see if any small business grants are available.
