Maryland Plumbing Code and Legislation
The state-level plumbing standards in Maryland are primarily governed by the Maryland Board of Plumbing, which operates under the Maryland Department of Labor. The state adopts model codes published by the International Code Council (ICC) to establish minimum installation standards for plumbing systems, including potable water, drain-waste-vent (DWV) systems, and fuel gas piping.
While Maryland establishes statewide standards, it is important to note that certain jurisdictions, specifically Baltimore County and areas served by the Washington Suburban Sanitary Commission (WSSC), maintain their own independent licensing requirements and may enforce their own specific plumbing codes. Practitioners should always verify the specific code edition and any local amendments with the local authority having jurisdiction (AHJ) where the work is being performed.
