Nevada to Oklahoma: journeyman plumber license reciprocity
Nevada does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Oklahoma'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.
Out-of-state plumbing journeyman without a reciprocity agreement (all states except Arkansas)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A journeyman from any state other than Arkansas has no reciprocity route, because CIB publishes only the Arkansas plumbing agreement and OAC 158:30-5-4 requires a written agreement for the specific license sought. Under OAC 158:30-9-1.4 a journeyman from a state without an agreement, or from a jurisdiction with only local licensing, may request exam equivalency; if the Board has previously approved that jurisdiction's exam as substantially similar, the Oklahoma journeyman exam is waived on a certified letter from the licensing jurisdiction showing a current license in good standing, the license category, an exam score of 70% or higher and no pending discipline. CIB does not publish which jurisdictions' exams have been approved, and no equivalency form exists on the Plumbing Forms page. Otherwise the applicant files the Application for Plumbing Examination with notarized experience affidavits and a copy of the out-of-state license, which 'may expedite processing of the requirements' (OAC 158:30-9-1(k)(3)); out-of-state experience lawfully obtained counts toward the three-year requirement. The applicant pays $75 and must pass the Oklahoma plumbing journeyman exam through PSI with 75%. Oklahoma has no separate law exam for journeymen.
Vendor sites claim Oklahoma plumbing reciprocity with Texas, Colorado and Louisiana; none of those states appears on any CIB plumbing page, on the Plumbing Forms page (which offers only an Arkansas reciprocity application) or in OAC 158:30, so they are treated as default-path states here. Colorado's Plumbing Board has no reciprocal agreements at all. Which jurisdictions' exams the Board has approved for equivalency could not be confirmed from an official page. The exam pass mark is 75% under OAC 158:30-9-1(d), but the equivalency letter only needs a home-state score of 70% or higher. The exam code edition was in transition per CIB's '2026 Building Code Updates and Examination Transition Period' notice.

How Oklahoma licenses journeyman plumbers
Oklahoma journeyman plumber · “Unlimited Plumbing Journeyman”
Statewide license
Issued by Oklahoma Construction Industries Board (CIB), Plumbing Division
Oklahoma issues statewide plumbing journeyman licenses through the Construction Industries Board (CIB) under the Plumbing License Law of 1955 and OAC Title 158, Chapter 30, in Unlimited and Residential categories. An Unlimited Plumbing Journeyman applicant must be 18 and show three years of verifiable experience in the plumbing trade while employed by a licensed plumbing contractor (about 2,000 hours per year, so roughly 6,000 hours; Oklahoma hours count only while registered as an apprentice), or equivalent U.S. military experience, with a Committee-approved 1,000-hour program substituting for two years and a 500-hour program for one year. The applicant pays $75 ($25 application plus $50 initial license), and must score 75% on the Oklahoma plumbing journeyman exam administered by PSI ($92 per portion). CIB has one published plumbing reciprocity agreement, with Arkansas (effective October 21, 2024, journeyman only); other out-of-state journeymen may seek exam equivalency if the Board has approved their jurisdiction's exam, and a current out-of-state license otherwise expedites processing of the experience requirement. Journeymen must work under a licensed plumbing contractor, renew annually ($75) and complete six hours of continuing education every 36 months.
Why Nevada has nothing to transfer
Nevada journeyman plumber · “Journeyman Plumber (county/city card)”
Licensed by cities and counties
Nevada has no statewide journeyman plumber license. The Nevada State Contractors Board (NSCB) licenses plumbing and heating contractors under classification C-1 (NRS/NAC 624), issues licenses only to businesses with a qualifying individual, and its FAQ says it does not license individual journeymen, so an out-of-state journeyman plumber license has nothing to transfer to at the state level and is not needed to work for a licensed C-1 contractor in most of the state. A personal credential exists only under local building codes: Clark County Code Chapter 22.02 requires a plumbing qualified individual or a journeyman plumber on site for permitted plumbing work and issues a renewable county journeyman plumber certificate to people who pass the journeyman exam accepted by the Building Official (plumbing is the one trade for which the county code publishes an experience prerequisite for the exam), and the City of Reno requires anyone installing, altering or adding to a plumbing system to hold a valid journeyman certificate under Reno Municipal Code Title 14. Neither jurisdiction publishes a waiver of its exam for an out-of-state license: Clark County's only equivalency is for a certificate from its accepted testing agency or another Nevada political subdivision within the county, while Reno lets contractors with a reciprocal license from another city, county, state or country work inside the city for 12 months before they must obtain the Reno certification. The City of Las Vegas, Henderson and the rural counties were not surveyed for plumbing cards.
How local licensing works in Nevada
How local licensing works. NRS Chapter 624 licenses only contractors. A C-1 Plumbing and Heating license is issued to a business and qualified by an individual with four years of journeyman-or-higher experience within the past 15 years (NRS 624.260); the NSCB FAQ states that Nevada does not license individual journeymen. Whether a working plumber needs a personal card is decided by each county's or city's building administrative code, and only Clark County and Reno were confirmed to require one for plumbing.
Clark County (unincorporated Las Vegas valley, Laughlin and other unincorporated areas). Clark County Code §22.02.245 issues plumbing permits only to contractors holding an active Nevada C-1 license. §22.02.250(B) requires the permit-holding contractor to employ at least one plumbing qualified individual and to have a qualified individual or a journeyman plumber present in a supervisory capacity while permitted plumbing work is under way. §22.02.255 defines a journeyman as someone who has passed the appropriate journeyman examination accepted by the Building Official and makes the county photo certificate renewable; the plumbing category is the only one in §§22.02.255-.260 for which the code publishes an experience prerequisite before the applicant may sit the exam (the exact number of years could not be re-extracted from the county PDF on 2026-09-16 and should be confirmed with the Department of Building and Fire Prevention). The only equivalency in the code (§22.02.255) is for a current certificate from an accepted independent testing agency or from a political subdivision of Nevada within Clark County, on obtaining the county photo certificate at the holder's expense; there is no provision for other states' journeyman licenses, so an arriving plumber must sit the county-accepted exam. The county's current exam vendor and card administrator for plumbing were not confirmed from an official page.
City of Reno. Reno's Development Services page states that no person may perform installations, alterations or additions to a plumbing system in the city unless done by a holder of a valid journeyman certificate, that apprentice plumbers must carry a card from an approved apprenticeship program, and that the requirement does not apply to homeowners, to contractors who keep an on-site written agreement naming the certified supervisors of their subordinate employees, or to 'contractors with reciprocal licenses from another city/county/state/country' for their first 12 months of work inside the city limits, after which the Reno plumbing certification must be obtained. Out-of-state experience is useful only as evidence toward Clark County's experience prerequisite and, for those who want to contract, toward the NSCB's four-year qualifying-individual requirement.
