Delaware to Rhode Island: journeyman plumber license reciprocity

Rhode Island issues a statewide Journeyperson Plumber license through the Department of Labor and Training (DLT) Board of Examiners of Plumbers (R.I. Gen. Laws ch. 5-20). Duties transferred to DLT under § 5-20-39; the Department of Business Regulation does not license plumbers. A Rhode Island-trained applicant is admitted to the DLT-administered journeyperson examination after holding a DLT apprentice-plumber registration for at least four years with 8,000 hours of on-the-job training in a five-year period and 576 hours of related instruction, or after specified college/associate-degree plus in-state apprenticeship paths, and paying a $75 nonrefundable application fee (§ 5-20-17). The same section admits an applicant who holds a journeyperson plumber certificate issued under the laws of another state if that state’s requirements are the same as Rhode Island’s — that is an exam-admission rule, not a waiver of the Rhode Island exam. Chapter 20 has no reciprocity or endorsement title, and DLT publishes no partner-state list. Cities issue plumbing permits under § 5-20-26 but do not replace the state license. Irrigator and water-filtration licenses under the same board are separate credentials.

Delaware does not issue a journeyman or journeyperson plumber license. The Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners licenses only master plumbers (and master HVACR / master HVACR restricted), and 24 Del. C. § 1807(c)(1) lets an apprentice, journeyman, mechanic or other person provide plumbing services without a Board license while working under the supervision of a master plumber who is their employer or a full-time employee of the same business. An out-of-state journeyman plumber license therefore has nothing to transfer to in Delaware and is neither required nor recognized as a Delaware credential for employment. Delaware's own 'journeyman's certificate' in 24 Del. C. § 1808(a)(1) is a certificate of completion from a plumbing apprenticeship that meets or exceeds federal BAT/OA standards, issued in any state: it is an experience credential used toward the Master Plumber license, not a license. With that certificate, two years of post-apprenticeship work under a master plumber (or a similar-level licensee in another state) qualifies an applicant for the master exam; without it, seven years of such supervised experience plus the apprenticeship equivalency (bypass) tests are required. Out-of-state journeyman hours gained under a licensed master count toward those master-exam experience requirements.
