State License
STATE Master PlumberDC DOB
Plumbing contractors operating in Washington, D.C., must adhere to a strict regulatory framework managed primarily by the Department of Buildings (DOB). All plumbing work, ranging from minor repairs to major installations, requires the oversight of a licensed Master Plumber who holds a valid District license. Compliance begins with ensuring your business is properly registered and that you maintain a 'Clean Hands' status regarding local tax obligations.
Permitting is a critical component of the process; work performed without a permit is subject to stop-work orders and significant fines. Contractors are responsible for scheduling inspections at various stages of the project to verify adherence to the International Plumbing Code as adopted by the District. Failure to maintain proper documentation or to secure necessary permits can result in the revocation of licensure and legal penalties.
