Michigan's plumbing industry is regulated by the Department of Licensing and Regulatory Affairs (LARA) through its Bureau of Construction Codes (BCC), requiring a specific license for nearly all plumbing work. This guide outlines the official pathways from Apprentice registration to Journey Plumber, Master Plumber, and Plumbing Contractor designations, detailing the precise requirements for each step to ensure you can get licensed correctly and legally.
Do You Need a Plumbing License to Work in Michigan?
Yes, Michigan requires a specific license for any individual performing plumbing work, with credentials issued for apprentices, journey plumbers, master plumbers, and plumbing contractors. The Michigan Department of Licensing and Regulatory Affairs (LARA) and its Bureau of Construction Codes (BCC) oversee all licensing and registration for the plumbing trade to ensure work meets state safety and quality standards. The scope of regulated work is defined by the Michigan Plumbing Code and state statutes.
Michigan Plumbing License Tiers & Requirements
The Bureau of Construction Codes issues four primary credentials for plumbing professionals, each with distinct requirements that build upon the previous level.
Plumbing Apprentice (Registration)
An individual learning the trade must be registered as a Plumbing Apprentice with the state. This registration allows them to work and gain the required experience under the direct supervision of a licensed Journey or Master Plumber. Active registration is the first step in the licensing pathway.
Journey Plumber License
To become a licensed Journey Plumber, you must first gain extensive hands-on experience as an apprentice and then pass a state examination.
- Experience: Applicants must document at least 6,000 hours of practical experience in plumbing installation, attained over a period of no less than three years as a registered plumbing apprentice. This work must be supervised by a licensed Master or Journey Plumber.
- Examination: Candidates must pass the state-administered Journey Plumber examination.
Master Plumber License
The Master Plumber license represents the highest level of technical qualification for an individual plumber in Michigan.
- Experience: Applicants must hold a Journey Plumber license and document at least 4,000 hours of experience working as a journey plumber. This experience must be gained over a period of no less than two years immediately preceding the date of the application. Any lapses in your Journey Plumber license during this two-year period will not meet the requirement.
- Examination: Candidates must pass the state-administered Master Plumber examination.
Plumbing Contractor License
A Plumbing Contractor license is required for any business entity that offers plumbing services to the public.
- Master Plumber Requirement: The business must either be owned by a licensed Master Plumber or employ at least one full-time licensed Master Plumber who is designated as the master plumber of record. This individual is responsible for the proper supervision and control of all plumbing work performed by the company.
- Business Registration: The business must be properly registered to operate in Michigan.
- Insurance: The contractor must meet state insurance requirements.
Michigan Plumbing License Application Process (Step-by-Step)
The process involves gaining the necessary experience, applying to the state for examination approval, passing the exam, and then submitting the final application for your license.
Step 1: Meet and Document Experience Requirements
Before applying, ensure you meet the specific experience thresholds for the license you are seeking. For a Journey Plumber license, this means 6,000 hours over three years as a registered apprentice. For a Master Plumber license, it means 4,000 hours over two years as a licensed Journey Plumber. Meticulously track and document this experience, as it must be verified.
Step 2: Apply for Examination Approval through LARA/BCC
Submit an application to the Bureau of Construction Codes to get approval to sit for the exam. Use the appropriate form for your license tier, such as the Application for Plumbing Examinations (BCC-329) for Master Plumbers or the Journey Plumber Application for journey-level candidates. You will need to provide supporting documentation, including affidavits or other proof of your qualifying experience.
Step 3: Schedule and Pass the State Examination
Once LARA/BCC approves your application, you will receive instructions on how to schedule your examination.
- Testing Service: The Michigan plumbing examinations are administered by a third-party testing service on behalf of LARA. Per the Bureau of Construction Codes, this service is currently PSI.
- Scheduling: You can schedule the written portion of the exam by contacting PSI directly at 1-855-579-4635 or through their website.
- Exam Content: The exams are computer-based and cover topics such as the Michigan Plumbing Code, practical plumbing knowledge, and trade-specific calculations.
Step 4: Submit Final License Application & Pay Fees to LARA/BCC
After passing your exam, you will complete the final steps to have your license issued.
- Application Fees: Pay the required license fee directly to the State of Michigan.
- Plumbing Contractor: $300.00
- Master Plumber: $300.00
- Journey Plumber: $40.00
- Payment: Follow the instructions on the application for acceptable payment methods.
Step 5: Secure Required Insurance (Plumbing Contractors Only)
If you are applying for a Plumbing Contractor license, you must provide proof of the following to LARA/BCC:
- Worker's Compensation Coverage: File evidence of active worker's compensation insurance.
- Certificate of Liability Insurance: Submit a certificate of liability insurance. The specific minimum coverage amounts are set by the Bureau; confirm the current requirements with the LARA/BCC licensing section before purchasing a policy.
- Responsible Master Plumber: Identify the licensed Master Plumber who will serve as the master plumber of record for the business.

Renewing Your Michigan Plumbing License

Michigan Plumbing License Reciprocity
Michigan does not have a general reciprocal plumbing license agreement with any other state. However, out-of-state applicants may be evaluated on a case-by-case basis. The Bureau of Construction Codes (BCC) has a process to review applications from individuals who hold a "substantially equivalent" license from another jurisdiction. If your prior training, experience, and examination are deemed equivalent to Michigan's standards, you may be approved for licensure. Contact the LARA/BCC licensing section directly to inquire about this process before applying.
