Where a Colorado master plumber license transfers

Colorado issues a statewide Master Plumber license through the State Plumbing Board in DORA's Division of Professions and Occupations. By examination an applicant must document five full-time years (8,500 hours) of practical plumbing experience on Affidavit of Experience forms, pay a $140 application fee, and score 75% on the PSI-administered Colorado master exam (120 multiple-choice questions, 270 minutes) based on the 2021 IPC/IRC adopted in 3 CCR 720-1. A master plumber may perform and supervise all plumbing work and is the responsible individual for a registered Plumbing Contractor, which is the separate business registration (with $100,000 property damage and $300,000 general liability insurance and workers' compensation compliance) needed to contract for plumbing work; a master may be responsible for only one company. Out-of-state master plumbers may be licensed by endorsement under Board Rule 1.4(B)(1)(a) without the Colorado exam; the Board has no reciprocal agreements. Licenses expire on the last day of February of odd-numbered years with eight CE hours per licence year.
