Issued by DC Board of Industrial Trades (Department of Licensing and Consumer Protection)

The District's highest person-held plumbing credential is the Master Plumber/Gasfitter license issued by the Board of Industrial Trades (DLCP); a Master Gasfitter specialty also exists. A Plumbing Contractor license is a separate business credential that must name a designated DC-licensed master and post a plumbing and gasfitting bond. Under D.C. Code § 47-2853.122(c) a master applicant must hold a valid journeyman plumber or gasfitter license, or have met the journeyman subsection (b) requirements, and have worked as a journeyman plumber or journeyman gasfitter for at least 4 years, then pass the PSI-administered master exam. Fees are a $65 application fee and a $120 master license fee for a term of up to 2 years ($155 on renewal); licenses expire March 31 of even-numbered years. The Board publishes a Maryland plumbing-professionals reciprocity bulletin; no Virginia plumber reciprocity is named on the board page.
