Welcome to our home page. The Maryland State Board of Plumbing licenses and regulates individuals who provide or assist in providing plumbing and gas services in Maryland. The Board also issues natural gas fitter licenses to qualified individuals who are non-plumbers. Both of these types of licenses are required for work throughout the state except for Baltimore County and the areas served by the Washington Suburban Sanitary Commission (WSSC). These two jurisdictions issue their own licenses and have their own plumbing code. The State Plumbing Board also issues a certificate to qualified individuals who are non-plumbers to provide propane gas services throughout the entire state.
