District of Columbia Plumber License Renewal

Last reviewed October 2026 · 6 min read

Every District of Columbia plumbing, gasfitting and combined plumbing/gasfitting license from the DC Board of Industrial Trades (apprentice, journeyman, master and contractor) expires on March 31 of an even-numbered year, whenever it was issued, so the next deadline is March 31, 2028. You renew online through DLCP (the Department of Licensing and Consumer Protection) before the license expires. DLCP's fee schedule lists two-year renewals at $110 for an apprentice or journeyman, $155 for a master and $180 for a contractor, with a $50 late renewal fee; ask DLCP how long a late renewal stays open. Contractors and their designated masters also keep $5,000 surety bonds that must run to the same March 31.

At a glance

Who needs it: DC law defines a plumber as anyone who designs, installs, repairs or removes plumbing fixtures, brings or extends a water supply through pipes in any building or premises, or connects or repairs drainage to a sewer or drain, and a gasfitter as anyone who designs, fabricates, installs, tests or operates nonindustrial gas appliances and piping from the meter to the appliances. Unless licensed, nobody may call themselves a plumber, licensed plumber, journeyman plumber, journeyman gasfitter, master plumber or master gasfitter in DC
Licenses: Plumbing, gasfitting, or combined plumbing/gasfitting licenses for apprentices, journeymen and masters, and contractor licenses for companies. Apprentices work only under the direct personal supervision of a licensed master plumber/gasfitter or master gasfitter
Renews every: 2 years. Whenever it was obtained, every plumbing and gasfitting license expires on March 31 of an even-numbered year. Next: March 31, 2028
Renewal notice: DC law has DLCP mail a renewal notice by first class mail to your last known address at least 30 days before the license expires, or earlier if the rules say so, and DC's general licensing rules say at least 60 days. Not getting it doesn't relieve you of renewing on time
Deadline: Before the license expires: under DC law it can be renewed for another term before it expires if you apply on time, pay the renewal fee and meet the other requirements
Renewal fee: DLCP's fee schedule lists two-year renewals at $110 for an apprentice, $110 for a journeyman (all types), $155 for a master (all types) and $180 for a contractor. DLCP says fees aren't refundable, even if you withdraw the application
Late renewal fee: DLCP's fee schedule lists a $50 late renewal fee. DC's general licensing rules allow a late renewal within 60 days after expiration, after which you must apply for reinstatement. Ask DLCP before you count on it
Continuing education: DC law lets the Board set continuing education as a condition of renewal, and a renewal must show you met any it has set. None of DLCP's plumbing pages we checked names any hours: ask DLCP before you renew whether any apply to your license
Renew: Online through DLCP's renewal application for occupational and professional licenses; DLCP's online services sign in through a free Access DC account. A company's point of contact can renew and pay on a licensee's behalf. DLCP asks every occupational licensee for a photo and recommends uploading a recent one with the renewal. Licenses are sent by email
Bonds: A plumbing/gasfitting contractor needs a $5,000 surety bond for the company and a $5,000 bond for its designated master. The bonds must expire with the license, on March 31 of an even year, so renew them with it
Designated master: A contractor license needs a designated DC-licensed master, who supervises the work and confirms the designation from their own account
If it expires: Don't work on an expired license. DC law reinstates a license if you apply within 5 years after it expired, meet the current renewal requirements, pay the reinstatement fee and meet the Board's reinstatement requirements, which under DC's rules include showing you're fit to resume practice (DLCP lists $110 for an apprentice or journeyman, $155 for a master and $180 for a contractor). After 5 years you apply as a new applicant. DLCP's form is the Industrial Trades Reinstatement Application
Inactive status: You can ask to go inactive (DLCP lists $110 for an apprentice or journeyman and $155 for a master). You pay no renewal fee and may not practice while inactive. Under 5 years inactive you can come back by paying the fee and meeting the current renewal requirements; after 5 years you're treated as a new applicant unless the Board finds reasonable cause or excusable neglect
Display: DC law asks every licensee to display the license conspicuously, or keep it on file, at each place of business or employment, and to tell DLCP of a change of home, business or employment address
Contact: DLCP Occupational and Professional Licensing, 1100 4th Street SW, 2nd Floor, Washington, DC 20024. Phone (202) 671-4500

DC's electricians (November 30 of odd years) and refrigeration and air conditioning mechanics (September 30 of even years) renew with the same Board on their own dates.

How to renew

Check your license expires March 31, 2028 (every DC plumbing and gasfitting license expires March 31 of an even year). Watch for DLCP's renewal notice, and keep your address current with DLCP so it reaches you.
Ask DLCP whether any continuing education applies to your license this cycle: none of its plumbing pages names any hours.
Contractors: renew the company's and the designated master's $5,000 surety bonds so they run to the same March 31, and confirm your designated master's license is current too.
Renew online through DLCP before March 31, upload a recent photo, and pay $155 for a master, $110 for a journeyman or apprentice or $180 for a contractor.
Missed it? Stop plumbing and gasfitting work and ask DLCP right away whether you can still renew with the $50 late fee (DC's general licensing rules allow 60 days) or must file the Industrial Trades Reinstatement Application. DC law allows reinstatement within 5 years after the license expired; after that you start over as a new applicant.

The license isn't the only thing expiring

Most lapses that cost contractors work aren't the license itself. They're one of these, renewing on a different date:

Your company's and designated master's plumbing and gasfitting bonds, which must expire with the license on March 31 of an even year
Your apprentices' licenses, which expire on the same March 31
General liability insurance policy
Workers' compensation policy (or exemption)
Certificates of insurance (COIs) you've given to clients and GCs
Commercial auto insurance

LicenseLedger keeps every one of those dates in one place and emails you before each one expires, with reminders far enough ahead to finish CE and paperwork.
