Oregon to Connecticut: master plumber license reciprocity
Oregon does not issue a statewide master plumber license, so there is nothing to transfer. Here is Connecticut'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.
Contractor (P-1) by equivalent out-of-state license (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A master plumber or plumbing contractor licensed in any other state applies under DCP's 'Plumbing Contractor - Equivalent Out of State License' path. DCP reviews a single out-of-state license for equivalency to the P-1: the hours table requires 576 classroom hours matching Exhibit A and 12,000 on-the-job hours (8,000 plus two years / 4,000 as a licensed journeyperson). The applicant submits a copy of the license, official license verification, the laws and regulations that set the requirements met to obtain it, and the scope of work, with the non-refundable $150 application fee. If approved, CGS 20-333 and 20-334a(a)(1) still require the Connecticut contractor examination before the $150 initial license is issued—the origin license does not waive the trade exam. An applicant whose license is not found equivalent is not approved on this path and must document comparable journeyman service and training instead (CGS 20-334a(a)(1)(A)). DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction.
DCP's contractor out-of-state page gives two classroom-hour figures for the P-1: its example sentence says an equivalent license 'must have required 720 classroom hours and 12,000 hours of on the job training', while its hours table lists 576 classroom hours with 12,000 on-the-job hours. DCP's Exhibit A course list for the P-2 apprenticeship totals 720 hours (20 courses of 36 hours). Confirm the figure that applies to your license with DCP at [email protected]. The PSI candidate bulletin states that every contractor must pass both a trade exam and the Business and Law exam; a passed exam stays valid for two years.

How Connecticut licenses master plumbers
Connecticut master plumber · “P-1 Unlimited Plumbing Contractor”
Statewide license
Issued by Connecticut Department of Consumer Protection, Occupational and Professional Licensing
Connecticut has no license titled 'master plumber'; the top-tier personal credential is the P-1 Unlimited Plumbing Contractor, issued by DCP to an individual and permitting all plumbing and piping work under CGS 20-330 (permits and contracting with the public). Limited contractor classes cover narrower scopes (J-1, J-3, P-7, P-9, PP-1, SP-1). A new P-1 applicant needs two years as an unlimited licensed journeyperson or equivalent experience and training; the out-of-state equivalency table is 12,000 OJT hours (8,000 plus two years / 4,000) and 576 classroom hours matching Exhibit A. CGS 20-334a(a)(1)(A) lets out-of-state journeyman service count if DCP finds it comparable, and still requires the contractor examination. CGS 20-333a would allow an exam waiver only if the origin state reciprocates, and DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction. Fees are a $150 application fee and a $150 initial/renewal license fee; licenses expire annually on October 31.
Why Oregon has nothing to transfer
Oregon master plumber
No individual license at this level
Issued by Oregon Building Codes Division (Department of Consumer and Business Services) / State Plumbing Board
Oregon has no master plumber license and no other person-held plumbing credential above journeyman. ORS 693.095 permits the State Plumbing Board to adopt rules for a 'supervising plumber' license, but no such rule exists in OAR chapter 918, division 695, and the Building Codes Division's license table lists only the Journeyman Plumber (JP) and three limited specialty licenses (residential water-heater, water-treatment and solar heating and cooling installer) as individual plumbing licenses; the Journeyman Plumber is therefore the highest license an individual can hold. The business-side credential is the Plumbing Business (PB) license under ORS 447.040, issued by the Building Codes Division to a firm that already holds a Construction Contractors Board (CCB) license: the owner or corporate officer files the Contractor/Business License Application (form 440-2888) with a $150 non-refundable fee and the CCB number, no signing supervisor or qualifying-person experience is designated for a plumbing business, no exam is taken, and the license renews on a three-year cycle (all PB licenses next expire July 1, 2029). A plumbing business license 'does not authorize the contractor to work as a journeyman plumber,' and the business may not let anyone perform journeyman work without an individual JP license. An out-of-state master plumber therefore has nothing to transfer to at this level: to work with the tools they obtain the Journeyman Plumber license through the journeyman path (Idaho or Montana reciprocity, or experience credit plus the Oregon exam), and to contract they register a business with the Secretary of State, license it with the CCB, and add the $150 BCD Plumbing Business license.
