California to North Dakota: journeyman plumber license reciprocity
California does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is North Dakota'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 journeyman without a reciprocal agreement: application for the North Dakota journeyman examination (all states except SD, MN, MT)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
NDAC 62-02-01-01(2) provides that 'Applicants who are journeyman plumbers in other states who desire to work in this state in localities where a state journeyman license is required may make application for a journeyman examination and license,' with proof of the origin journeyman license 'vouched for as provided on the application blank.' The Board's FAQ adds that the applicant must meet NDAC chapter 62-02-01, must document four years and 7,600 hours as an apprentice working under a licensed master plumber, and must verify the out-of-state license 'by state endorsed letter which must state the type of license held, issue date of said license, whether the license was obtained through examination and whether or not the license is current.' Experience earned in states or localities that do not license plumbers is documented on the previous-practical-experience verification signed by the master plumber plus notarized letters from present and previous employers stating dates, hours and extent of work. The applicant pays the $50 application fee and $50 exam fee, must sit within six months of approval, and needs 70% on the five-part board-administered journeyman exam (2018 North Dakota Plumbing Code); the $100 journeyman license fee is paid on passing. NDCC 43-18-13.1 lets the Board register nonresidents without examination when their state's requirements are substantially equivalent and that state grants similar privileges, but the Board's published practice limits no-exam licensure to its three written agreements.
There is no separate law or rules exam; the journeyman exam covers the plumbing code and basic principles of plumbing (NDAC 62-02-01-03). The FAQ requires a 'state endorsed letter' to verify an out-of-state license, so a city-issued origin license is not recognized as a license, although the underlying hours can still be claimed through the master-signed verification and notarized employer letters used for non-licensing jurisdictions. NDAC 62-02-01-01(1) also offers a 'journeyman examination screening test' route (oral/written test plus a state-inspector report on an installation) for tradespeople with five years and 9,500 hours from localities without state licensing.

How North Dakota licenses journeyman plumbers
North Dakota journeyman plumber · “Journeyman Plumber”
Statewide license
Issued by North Dakota State Plumbing Board
North Dakota issues a statewide Journeyman Plumber certificate and license through the North Dakota State Plumbing Board under NDCC chapter 43-18 and NDAC chapter 62-02-01; a license is required wherever there is a public water or sewer system, and a journeyman may run a plumbing business only in cities under 1,000 population and rural areas. A new applicant must have served four years and 7,600 hours as a registered apprentice under a licensed master plumber (1,900 hours per year; accredited plumbing-school graduates earn credit by grade average), then pass the board-administered journeyman exam - five parts, two closed book and three open book, five hours, based on the 2018 North Dakota Plumbing Code - with 70%. Fees are a $50 application fee, a $50 exam fee and a $100 journeyman license fee; licenses expire every December 31 and renew for $100, with 2 to 4 hours of continuing education required in each two-year period ($40 board session). Exams are given every other month in Bismarck and Fargo and a failed exam carries a six-month wait. Journeymen from South Dakota, Minnesota and Montana may be licensed without examination under the Board's written reciprocity agreements; all other out-of-state journeymen apply for the North Dakota examination, with their origin license vouched for on the application.
Why California has nothing to transfer

Licensed by cities and counties
Issued by City and county building departments (no statewide journeyman plumber license)
California does not issue a statewide journeyman plumber or master plumber license. The only state plumbing credential is the C-36 Plumbing Contractor classification from the Contractors State License Board (CSLB), which is a contractor license qualified by a named individual, not a personal tradesperson card. Business and Professions Code §7053 takes wage employees outside the Contractors State License Law, so a plumber who works for a C-36 contractor needs no CSLB license; California's personal electrician certification (Labor Code §108) has no plumbing counterpart. Some cities and counties still examine and card journeyman plumbers (certificate of competency / journey-level plumber) for work in that jurisdiction. Those cards are not statewide, are not issued by CSLB, and an out-of-state journeyman plumber license is not recognized by any state board. An arriving journeyman should ask the building department where the job is whether a local plumber card is required and sit that city's exam; contracting independently requires a C-36 license, described at the master level.
How local licensing works in California
No state journeyman. CSLB's C-36 page and fee/reciprocity materials describe only contractor licensing. B&P §7053 leaves employed plumbers unlicensed at the state level. There is no DIR-style plumber certification.
How local cards work. Cities that still license individual plumbers typically issue a certificate of competency or journey-level plumber card after documented experience and a local exam. The card does not authorize contracting (that is C-36). Cards are not portable statewide; a Los Angeles card does not satisfy San Francisco, and vice versa. San Francisco DBI 'certificate-competency' redirected to the SF.gov Department of Building Inspection hub without the certificate list. City of San Diego /development-services/permits/contractor-licenses returned HTTP 404. Other cities and some counties may also card plumbers.
