Last verified: 2026-07-21 · source: Michigan Department of Licensing and Regulatory Affairs — Bureau of Construction Codes (BCC), Plumbing ↗
A plumbing license transfers from Washington to Michigan by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Michigan Department of Licensing and Regulatory Affairs — Bureau of Construction Codes (BCC), Plumbing, verify your Washington license, and meet Michigan's endorsement requirements. Michigan does not reciprocate with any state and waives its journey plumber exam for no one: every applicant, in-state or out, must pass Michigan's written AND practical (hands-on) journey plumber examinations. An out-of-state plumber may receive credit for out-of-state experience — documented on the BCC Out-of-State License Verification form — toward the 6,000-hour eligibility requirement to be approved to sit for the exam, but the examination is mandatory..
