Tennessee to Colorado: journeyman plumber license reciprocity
Tennessee does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Colorado's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Licensure by endorsement (all other states; no reciprocal agreements)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
Every out-of-state journeyman applies under the same endorsement rule, because the Colorado Plumbing Board has no reciprocal agreements (the word does not appear in 3 CCR 720-1 or on the DPO plumbing pages). Under Rule 1.4(B)(1)(a) and the DPO Licensure Requirements, the applicant must hold an active journeyman-level license issued and regulated by a state (not a city or county) for at least six months, must have obtained it by passing a comparable state plumbing exam based on the current or previous edition of the plumbing code adopted by the Board (the 2021 IPC; DPO's Licensing Guide phrases this as 'the current or previous version of the International Plumbing Code'), and must have completed a state or federally approved apprenticeship or the four years (6,800 hours) of experience Colorado requires, documented on the Board's Affidavit of Experience forms signed by employers (self-verification is not accepted). The issuing state board completes DPO's Verification of State Licensure form. An applicant who satisfies these conditions is licensed without taking the Colorado exam; anyone who does not (for example a licence gained without an exam, on a non-IPC code, or held under six months) applies by examination, where out-of-state hours still count toward the 6,800-hour requirement.
Wording differences between official sources: the DPO Applications page says the comparable exam must be 'based on the currently adopted Colorado Code', while Rule 1.4(B)(1)(a)(2) and the Licensing Guide accept the current OR previous edition of the adopted plumbing code (IPC). The six-month holding period appears on the DPO Applications page but not in the rule text. Rule 1.4(A)(1) says candidates 'must pass the required examination(s) before submitting an application', whereas the Applications page describes DPO approving the application first and then issuing PSI scheduling instructions; exam-route applicants should confirm the current order of operations with DPO. The $120 application fee is quoted as 'currently' in the DPO Licensing Guide; the PSI exam fee is set in PSI's candidate handbook and was not published on the DPO pages reviewed. C.R.S.

How Colorado licenses journeyman plumbers
Colorado journeyman plumber · “Journeyworker Plumber”
Statewide license
Issued by Colorado State Plumbing Board (DORA Division of Professions and Occupations)
Colorado issues a statewide Journeyworker Plumber license (its name for the journeyman level) through the State Plumbing Board in DORA's Division of Professions and Occupations; the Board also licenses Residential Plumbers (two years / 3,400 hours) and Master Plumbers, registers apprentices, and registers Plumbing Contractors, which must hold or employ a licensed master plumber. By examination a journeyworker needs four years (6,800 hours) of documented practical experience verified on Affidavit of Experience forms by plumbing contractors or employers, a $120 application fee, and a passing score of 70% on the PSI-administered Colorado journeyworker exam (100 multiple-choice questions, 240 minutes) based on the 2021 IPC/IRC as adopted in 3 CCR 720-1. Out-of-state licensees who meet Board Rule 1.4(B)(1)(a) may instead be licensed by endorsement without the Colorado exam; the Board publishes no reciprocal agreements with any state. Licenses expire on the last day of February of odd-numbered years, and renewal requires eight hours of continuing education per licence year (waived until after the first renewal for new exam licensees).
Why Tennessee has nothing to transfer
Tennessee journeyman plumber · “Journeyman plumber (city or county card only)”
Licensed by cities and counties
Tennessee has no statewide journeyman plumber license. The Board for Licensing Contractors licenses plumbing at two other levels only: the Limited Licensed Plumber (LLP), a personal license for projects under $25,000 in municipalities that use the Division of Fire Prevention for permits and inspections (T.C.A. § 62-6-403; photo ID, SSN, Prov LLP trade exam, $75 initial fee; general maintenance under $500 is exempt), and the contractor license with the CMC-A (plumbing) or CMC (full mechanical) classification, a business license required for plumbing work of $25,000 or more. The Board's LLP page tells applicants to check first whether the local government accepts the LLP or runs its own licensing. Journeyman plumber cards therefore exist only where a city or county examines plumbers itself. Metro Nashville's Mechanical, Plumbing, and Electrical Examiners and Appeals Board issues journeyman plumber (and apprentice plumber) certificates; Knoxville registers State Contractors, homeowners, or Unlicensed/State Limited License (LLE or LLP) holders to pull permits and does not publish a separate city journeyman plumber card on that page. An out-of-state journeyman plumber license has no state-level recognition in Tennessee: the Board's trade-exam-waiver form cannot be used for the LLP, and none of the city pages reviewed here publish a reciprocity or exam-waiver path for inbound journeymen.
How local licensing works in Tennessee
How local licensing works. T.C.A. Title 62, Chapter 6 gives the Board the CMC/CMC-A contractor license (business, $25,000 and up, accepted statewide for contracting) and the LLP (individual, under $25,000, only where the State Fire Marshal inspects). Cities and counties that run their own plumbing inspection programs may require a local journeyman or master plumber card instead of, or in addition to, the LLP. Each local card is valid only in that jurisdiction. The Board publishes no journeyman-to-journeyman reciprocity.
Nashville / Davidson County. The Mechanical, Plumbing, and Electrical Examiners and Appeals Board (Metro Code Chapter 2.76) examines applicants for master plumber, journeyman plumber and apprentice plumber certificates and issues those certificates (Codes and Building Safety, 800 President Ronald Reagan Way; 615-862-6500). Expect to sit Metro's exam unless Codes staff confirm otherwise.
Knoxville. Permits are pulled under a State Contractor registration, a Homeowner registration, or an Unlicensed / State Limited License (LLE or LLP) registration. The Plans Review & Inspections page does not describe a city-issued journeyman plumber license. No experience hours published. No out-of-state exam waiver. Accepted only where the Division of Fire Prevention inspects; many larger cities do not use that program.
