District of Columbia DC Plumbing License Requirements and Plumber License Verification, Renewal and Application

The District of Columbia DC The Board of Industrial Trades are the ones who you must apply with to become a licensed Plumbing Contractor or Journeyman Plumber in Delaware. The Board of Industrial Trades (Board) was established to protect the public health, safety, and welfare of the citizens of the District of Columbia by ensuring that individuals engaged in such occupations as asbestos workers, electricians, refrigeration and air conditioning mechanics, plumbers, steam & other operating engineers, have the specialized skills and training required to perform such services for the public. The Board license law, which governs plumbers, electricians, refrigeration and air conditioning mechanics, steam and other operating engineers, asbestos workers, elevator mechanics, elevator inspectors (except for those employed by the District of Columbia or by the Washington Metropolitan Area Transit Authority) and elevator contractors is defined by the District of Columbia Second Omnibus Regulatory Act of 1998 (Omnibus), which took effect on April 20, 1999. The Board may establish bonding and insurance requirements, subcategories of licensure, education, and experience requirements for licensure, and other requirements (excerpt from District of Columbia DC The Board of Industrial Trades official web site).
