Last verified: 2026-07-21 · source: Colorado State Plumbing Board — Department of Regulatory Agencies (DORA), Division of Professions and Occupations ↗
A plumbing license transfers from Michigan to Colorado by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Colorado State Plumbing Board — Department of Regulatory Agencies (DORA), Division of Professions and Occupations, verify your Michigan license, and meet Colorado's endorsement requirements. Colorado has no bilateral state-to-state reciprocity; it licenses out-of-state plumbers by endorsement, accepting successful completion of a comparable state plumbing examination (based on a plumbing-code edition adopted by the Colorado board) in lieu of the Colorado examination, provided the applicant currently holds an active license in the endorsing state and meets the apprenticeship/experience requirement; applicants who cannot document a comparable exam must qualify and pass the Colorado examination.

Verdict
Licensure by endorsement
Michigan is not among the states Colorado names for an automatic exam waiver, so this move runs on the Colorado State Plumbing Board — Department of Regulatory Agencies (DORA), Division of Professions and Occupations's individual endorsement or equivalency review rather than a guarantee. Colorado has no bilateral state-to-state reciprocity; it licenses out-of-state plumbers by endorsement, accepting successful completion of a comparable state plumbing examination (based on a plumbing-code edition adopted by the Colorado board) in lieu of the Colorado examination, provided the applicant currently holds an active license in the endorsing state and meets the apprenticeship/experience requirement; applicants who cannot document a comparable exam must qualify and pass the Colorado examination. Bring your Michigan license, proof that it is active and in good standing, and your apprenticeship and exam records — and get any discretionary exam or experience credit in writing before you rely on it.
