New York to District of Columbia: journeyman plumber license reciprocity

The District of Columbia issues a person-held Journeyman Plumber license (the Board also licenses journeyman gasfitters as a related specialty) through the Board of Industrial Trades in the Department of Licensing and Consumer Protection (DLCP), the same board that licenses electricians and refrigeration mechanics. Under D.C. Code § 47-2853.122 a journeyman plumber must have worked as an apprentice plumber or gasfitter at least 8,000 hours over at least 4 years (a mechanical-engineering degree plus 2 years of practical experience verified by a licensed master, or comparable experience the Board accepts, also qualifies) and then pass the PSI-administered exam, unless the applicant presents a national certifying organization's journeyman plumber certificate that waives both the exam and the subsection (b) experience path. Fees are a $65 application fee and a $110 license fee for a term of up to 2 years; plumber and gasfitter licenses expire March 31 of even-numbered years. The Board publishes a Maryland plumbing reciprocity bulletin; the Reciprocity section of the board page still describes only Maryland and Virginia electricians. No District-law exam applies to journeyman plumbers (§ 47-2853.12(c)(3)).

New York has no statewide plumber licence at any level: the Department of State's Division of Licensing Services regulates 35 occupations and none of them is plumber, plumbing contractor, journeyman plumber or master plumber. Journeyman-level plumbing credentials therefore exist only where a city or county ordinance creates them, and they are not interchangeable. New York City's Department of Buildings issues a Journeyman Plumber / Fire Suppression Piping Installer registration (employees work under a licensed Master Plumber; the registration is not an independent contracting licence). Westchester County issues a Journey-Level plumber licence (exam application $25, licence and renewal $75) that is required to work as a plumber anywhere in the county, including Yonkers. Rochester publishes a Plumbing Licensing programme on its Licensed Trades page but does not list class names or fees on that page. An out-of-state journeyman plumber licence has no state-level recognition in New York; the arriving worker must satisfy the city or county where the work will be done, and in New York City that typically means working under a licensed Master Plumber while holding (or obtaining) the city journeyman registration.
