Who needs a plumbing license?
Plumbers and plumbing contractors generally need a license, often tiered (apprentice, journeyman, master). Most states license plumbing at the state level.
A plumbing contracting business may need a separate company registration in addition to the individual license.
District of Columbia specifics
DC licenses plumbers and gasfitters through the Board of Industrial Trades; those licenses expire March 31 of even-numbered years.
Why a lapse hurts
Working on an expired plumbing license risks fines, failed inspections, and liability, and permits typically require an active license.
Letting it lapse can pull you off jobs and may require re-examination or reinstatement fees.
How renewal works
Renew with your state plumbing or contractor board before expiration, pay the fee, and complete any required continuing education.
Cycles are commonly one to three years; keep your CE records for renewal.
Never miss this renewal again
Add your plumbing license and every other permit to Renovo and get automatic reminders before each one expires. Free for one business.
