How Do You Get a Plumbing License in Utah?

Yes.

Utah licenses plumbers statewide through the Utah Division of Professional Licensing (DOPL).

DOPL's own pages list five plumber license classifications: Apprentice, Journeyman, Master, Residential Journeyman and Residential Master.

The license ladder starts at the bottom rung: Utah plumbing apprentices hold a DOPL Apprentice Plumber license, with the employer signing a Verification of Supervision form, rather than working unlicensed.

DOPL's five plumber classifications are Apprentice, Journeyman, Master, Residential Journeyman and Residential Master.

The Apprentice Plumber license is the entry rung: it has no exam, and the employer signs a Verification of Supervision form.

Journeyman Plumber is reached through supervised hours and a written theory exam plus an in-person practical; Master Plumber adds 4,000 hours of supervisory experience as a licensed journeyman plus the Utah Master Plumber Law and Rule exam.

Two residential classifications — Residential Journeyman and Residential Master — round out the five.

Above the individual licenses sit DOPL's plumbing contractor classes, P200 General Plumbing Contractor and P201 Residential Plumbing Contractor; both require the Utah Business and Law exam and a master plumber classification.

Our research captured each level's entry requirements and exams, not a legal scope statement per classification, so confirm with DOPL what a residential license covers before you rely on the name.

Apprentice Plumber: no exam, and your employer signs a Verification of Supervision form.

Journeyman Plumber: DOPL's application page lists two routes — complete a plumber apprenticeship education program (576 classroom hours) plus 8,000 hours of supervised experience, or log 16,000 hours of supervised experience.

DOPL's exam-information page describes the education route differently (7 semesters and 6,000 hours), so confirm the education-route hours with DOPL before you plan around them.

Residential Journeyman Plumber: 6,000 hours as a licensed apprentice plus a 3-year approved education program of at least 432 classroom hours, or 12,000 hours of supervised experience.

Master Plumber: 4,000 hours of supervisory experience as a licensed journeyman, or an AAS degree plus 2,000 hours.

Utah requires the hours and schooling to be complete before you are approved to sit the journeyman or master exam.

Our research did not confirm Utah plumbing application or license fees — ask DOPL for current amounts.

The journeyman plumber exam runs through Prov.

Journeyman plumber candidates take a written theory exam, which can be taken remotely through Prov's ExamRoom AI, and a practical exam that must be taken in person at an approved Utah Prov testing center.

Residential journeyman candidates take the Utah Residential theory and practical exams, and master applicants take the Utah Master Plumber Law and Rule exam; our research did not capture the exam vendor for those two.

The Apprentice Plumber classification has no exam.

Approval comes first: Utah requires your on-the-job work hours and school hours to be met before you are approved to take the journeyman or master exam.

Our research did not capture a content outline for any Utah plumbing exam — DOPL's plumbing exam-information page is the place to check what each covers.

Utah plumbers need 12 hours of approved CE per licensing cycle, at least 8 of them core.

DOPL states the requirement per licensing cycle; our research did not capture the length of the cycle for plumber licenses or the renewal fee, so confirm both with DOPL before your renewal comes due.

The route our research confirms for out-of-state plumbers is endorsement: DOPL grants plumber licenses by endorsement to holders of equivalent licenses from other states, and it publishes an endorsement map for checking qualification.

One equivalence is explicit: DOPL considers the Canadian Plumber Red Seal Certification equivalent to the Utah Journeyman Plumber license through the endorsement route, where the Red Seal has been held for 1+ year.

Our research captured no Utah agreements naming specific partner states, so check DOPL's endorsement map before you count on another state's license in Utah.

Our research points to a Verify a License tool on DOPL's commerce.utah.gov pages, but we did not find the tool or its address confirmed in the pages we read — start from DOPL's plumbing pages and follow the verify-a-license link from there.

Search it before you take a job arranged under someone else's Utah plumbing license, and again once your own is issued to confirm the record shows the right classification and status.

Gas work carries its own individual credential in Utah, separate from DOPL's plumbing classifications.

Under state rule R156-55a, work on gas piping, combustion-air vents, exhaust venting or altitude derating of gas appliances requires the Certified Natural Gas Technician certification, an individual certification that applies even to HVAC workers.

It is earned through an approved training program — the rule names federal apprenticeships, Utah college apprenticeship programs, trade union apprenticeships, the Rocky Mountain Gas Association (RMGA) and the Home Builders Association of Utah — and the RMGA Gas Appliance Installers exam, or an approved equivalent, with at least 80%.

The plumber shortcut: a current Utah Journeyman or Residential Journeyman plumber license counts as documentation of exemption from the natural gas technician certification.
