Delaware to Indiana: journeyman plumber license reciprocity

Indiana licenses plumbers statewide through the Indiana Plumbing Commission, which is administered by the Professional Licensing Agency (PLA) under IC 25-28.5-1. The Commission registers Plumbing Apprentices and approves apprenticeship programs and schools, and it issues Journeyman Plumber and Plumbing Contractor licences to individuals, a Temporary Plumbing Contractor licence, and a Corporate Plumbing Business registration for entities. Applications, renewals and licence verification are handled online in MyLicense One with an Access Indiana account. The Indiana journeyman examination is administered by the testing vendor PROV, and initial licence fees are prorated by whether the licence is issued in an odd or even year of the two-year cycle. Indiana's statute contains a reciprocity section (IC 25-28.5-1-19) and a nonresident provision (IC 25-28.5-1-12), so an out-of-state journeyman applies to the Commission rather than to any city or county.

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.
