Checking a plumber in the Washington area
Plumber licenses in District of Columbia
Plumbers are licensed by the state.
Who licenses: DC Department of Licensing and Consumer Protection (DLCP), Board of Industrial Trades
License types: Apprentice Plumber/Gasfitter, Journeyman Plumber/Gasfitter, Master Plumber/Gasfitter, Plumbing Contractor.
Businesses: The Board of Industrial Trades issues a separate Plumbing Contractor license (renewed every two years, with a plumbing and gas fitting bond form on file).
Check a license: govservices.dcra.dc.gov
Confirm the company's DC Plumbing Contractor license and the plumber's journeyman or master license on DLCP's online license verification before hiring.
We could not confirm every detail from District of Columbia’s own sources, so treat this as a starting point and check with the agency.
Sources: dlcp.dc.gov, dlcp.dc.gov, dlcp.dc.gov. Checked October 2026 from official sources. This is not legal advice.
Plumber licenses in Maryland
Licensing is split between the state and local governments.
Who licenses: Maryland State Board of Plumbing (Maryland Department of Labor)
License types: Master Plumber/Gas Fitter, Journey Plumber/Gas Fitter, Apprentice Plumber/Gas Fitter, Master Natural Gas Fitter, Journey Natural Gas Fitter, Apprentice Natural Gas Fitter.
Businesses: Journey and apprentice plumbers work under the direction and control of a licensed master plumber; the Board's requirements page does not list a separate plumbing contractor license.
Local rules: WSSC Water runs its own plumber and gasfitter licensing within its service district (it reciprocates Maryland State, Baltimore County and Virginia licenses), and Baltimore County issues its own gas fitter licenses.
Check a license: dllr.state.md.us
Verify the plumber's Maryland license with the Board of Plumbing's online search, and if you are in the WSSC Water service area, also check WSSC's plumber lookup.
We could not confirm every detail from Maryland’s own sources, so treat this as a starting point and check with the agency.

License types: Residential Plumber (tradesman), Journeyman Plumber (tradesman), Master Plumber (tradesman), Class A / B / C Contractor with Plumbing (PLB) specialty.

Check a license: dpor.virginia.gov
