Plumber License from North Carolina to District of Columbia: Does It Transfer? (2026)
Last verified: 2026-07-21 · source: District of Columbia Board of Industrial Trades — Department of Licensing and Consumer Protection (DLCP), Occupational and Professional Licensing ↗
A plumbing license transfers from North Carolina to District of Columbia by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the District of Columbia Board of Industrial Trades — Department of Licensing and Consumer Protection (DLCP), Occupational and Professional Licensing, verify your North Carolina license, and meet District of Columbia's endorsement requirements. The District has no state-to-state plumber reciprocity — the Maryland/Virginia trade reciprocity DLCP publishes applies to electricians, not plumbers. DC waives its journeyman plumber examination only for applicants who prove completion of a nationally-certified apprenticeship program; all other applicants qualify by documenting experience (journeyman: 4 years / 8,000 work hours) and must pass the DC journeyman plumbing exam (open-book on the 2012 International Plumbing Code and 2012 International Fuel Gas Code). The master tier requires 8 years / 16,000 hours and its own exam.
