Utah DOPL Plumbing License: Apprentice to Master, Prov Exams, and the Master Plumber a P200 Needs (2026)

Utah DOPL, the Utah Division of Professional Licensing, issues every plumber license in the state: apprentice, journeyman, residential journeyman, master and residential master. If you searched "DOPL plumbing license" and landed here from Idaho, note that Idaho's licensing agency is also called DOPL (the Division of Occupational and Professional Licenses), and its hours, exams and fees are different. Everything below is Utah.

This guide walks the Utah ladder as DOPL and its exam vendor Prov run it today, then covers the step most plumbers hit later: a plumbing contractor license needs a specific person in a specific role. For the full contractor picture see the Utah contractor license requirements, and for every other state see how to get a contractor license in each state.

Utah DOPL, Not Idaho DOPL: Who Issues Utah Plumbing Licenses

Plumbing licenses in Utah come from the Utah Department of Commerce, Division of Professional Licensing. Its office is on the 4th floor of the Heber M. Wells Building at 160 East 300 South in Salt Lake City, and its mailing address is P.O. Box 146741, Salt Lake City, UT 84114-6741. The phone line is (801) 530-6628.

Older forms still say "Division of Occupational and Professional Licensing"; it is the same Utah agency under its current name.

The law behind the license is the Utah Construction Trades Licensing Act, Utah Code Title 58, Chapter 55. The rules that carry it out are Utah Admin. Code R156-55a (the contractor side) and R156-55c, the Plumber Licensing Act Rule, which sets the plumber hour routes, exams, continuing education and apprentice supervision.

A change is coming on January 1, 2027. H.B. 40 from the 2026 General Session restructures the Construction Trades Licensing Act on that date and moves the plumber qualifications into a new section, 58-55-404, which the Utah Legislature's own code site already marks superseded as of that date. The new section reframes several routes in years rather than banked hours: journeyman becomes four years of full-time apprentice training or eight years of division-approved experience, master plumber becomes two years of supervisory experience as a journeyman (or an AAS degree plus one year), and residential master becomes two years of supervisory experience as a residential journeyman. Each also keeps an expedited-licensure path the commission will define by rule. Until January 1, 2027, the section numbers and hour figures cited on this page are the law in force, and this page will update again once the new section takes effect.

The Five Utah Plumber Licenses

DOPL's exam page lists five plumber license classifications. The residential track has its own journeyman and master and asks for fewer hours, so a plumber who works on houses may never need the unlimited license.

Notes on the table

• Practical exam: a master candidate who already passed the Utah Plumber Practical for a journeyman or residential journeyman license does not take it again, per the DOPL exam page.
• Hour crediting: no more than 3,000 hours count toward licensure in any 12 month period, per Utah Admin. Code R156-55c-302a(8) and the plumber application.

Apprentice Plumber: Where the Hours Start

The apprentice license is the entry point, and DOPL requires no exam for it. What it does require is an employer: your employer completes and signs the Verification of Supervision form, naming your supervising plumber, and the application carries a $116 non-refundable processing fee payable to DOPL.

Register early: every hour that counts toward journeyman has to be earned as a licensed apprentice.

Under Utah Code 58-55-302(3)(e), a licensed apprentice plumber works under the immediate supervision of a licensed master, residential master, journeyman or residential journeyman plumber. Beginning in the fourth year of training, an apprentice may work without supervision for up to eight hours in any 24 hour period.

R156-55c-401 caps the ratio at three licensed apprentices under immediate supervision per licensed supervisor, on residential and non-residential projects alike. The same rule lets a plumbing contractor meet the supervision requirement by contracting with a licensed professional employer organization that employs licensed plumbers.

Journeyman Plumber Requirements

DOPL's journeyman application page lists two routes to the unlimited working license:

1. Complete a plumber's apprenticeship education program of 576 classroom hours, log 8,000 hours of licensed plumbing experience under a licensed journeyman or master plumber, and pass the Utah Plumbing Theory and Practical exams.
2. Log 16,000 hours of licensed plumbing experience under a licensed journeyman or master plumber, and pass the same two exams.

The statute frames the same choice in years: four years of full-time training in an approved program, or eight years of full-time experience approved by the division (Utah Code 58-55-302(3)(c)). R156-55c-302a(3) sets the hour figures above and adds a third route for residential journeymen moving up: 2,000 hours of non-residential work as a licensed apprentice plus the fourth year, 144 hours, of the program.

Testing before you finish school. DOPL's exam information lists a separate test eligibility route for school route candidates: completion of the first semester of the fourth year of the program, enrolled in the second, with at least 6,000 hours logged. That comes from R156-55c-302b(4)(b). That is when you may test, not when you may be licensed; the license still needs the finished 576 hour program and 8,000 hours.

A program counts as finished only with at least 72 classroom hours each semester and a score of 75 percent in each class (R156-55c-302a(6)). Prov's competency exams can also satisfy the education requirement or set your placement in a program (R156-55c-302c).

A Canadian Red Seal plumber who has held it at least one year can apply for journeyman by endorsement, per DOPL's plumbing FAQ, which treats the Red Seal certification as equivalent to the Utah Journeyman Plumber license.

Residential Journeyman Plumber: The Utah Residential Plumbing License

The residential track is shorter, and for a company doing single-family work it is often the right credential rather than a consolation prize. Utah law defines a "residential building" for these licenses as a single or multiple family dwelling of up to four units (Utah Code 58-55-102(43)).

DOPL's residential journeyman page lists two routes:

• 6,000 hours as a licensed apprentice under a licensed journeyman or master plumber, plus a 3 year approved program of at least 432 classroom hours; or
• 12,000 hours of full-time work in a maintenance or repair trade, at least 9,000 of them in plumbing (R156-55c-302a(4)(b)).

Either way, you pass the Utah Residential Plumbing Theory Exam and the Utah Plumber Practical Exam.

Master Plumber and Residential Master Plumber

Master Plumber. R156-55c-302a(1) sets two routes: at least 4,000 hours of work experience and 4,000 hours of supervisory experience as a licensed journeyman, or an Associate of Applied Science degree (or a similar degree from a school recognized by the Council for Higher Education Accreditation, CHEA) plus 2,000 supervisory hours as a licensed journeyman. The two 4,000 hour categories may be earned at the same time, and supervisory hours must be earned as a W-2 employee. Both routes end with the Utah Master Plumber Law and Rule Examination.

Residential Master Plumber. R156-55c-302a(2) mirrors it: 4,000 work hours and 4,000 supervisory hours as a licensed residential journeyman, or the AAS degree plus 2,000 supervisory hours. DOPL's own apply-for-residential-master-plumber page and its exam information page both name the same Utah Master Plumber Law and Rule exam for this license, plus the Utah Plumber Practical if not already passed.

The master exam is a law and rule exam, not a trade exam. It covers Utah construction trade statutes, DOPL rules, labor law, safety reporting and other state regulations, and the pass mark is 75 percent.

You pass it before you apply. DOPL's master page states, "All applicants will be required to pass the Utah Master Plumber Law and Rule exam," and its exam page adds that an application should not be submitted until all required exams are passed and other licensing requirements are met.

Utah Plumbing Exams With Prov

Utah plumbing exams are administered by Prov, Inc., under contract to the Plumbing Board. Prov's redesigned Utah Plumbing Candidate Information Bulletin (Document UT UtahPlumbing CIB 2026.10.20, effective October 20, 2026) sets the numbers below.

Notes on the exams

• Written content: the Journeyman theory exam weighs drain, waste and vent work heaviest (20 of 100 questions), then water supply (15) and indirect and special waste (10), with the 2024 International Plumbing Code among the open-book references, per the Prov bulletin.
• Practical content: one PVC assembly and one copper assembly, worth 37 points each, and one of the two includes a rolling offset. Candidates bring their own tools and materials and may not share them; the exam is scored to the same 70 percent standard as the written exams, not pass or fail.
• Results: Prov's scoring system grades the exam immediately on completion and forwards results to DOPL automatically.
• Retakes: a failed exam can be retaken after 30 days at the same fee. Utah Admin. Code R156-55c-302b(5) sets the wait at 120 days following any failure after the sixth. Prov's current bulletin text states a shorter 90-day wait in that same spot, so confirm the live figure with DOPL or Prov before relying on it.

Registration now needs a UtahID. Every candidate must hold a UtahID, the state's digital identity account, created free at id.utah.gov, and must register with Prov using the email tied to that UtahID. Since January 19, 2026, every first-time candidate must also attach the Verification of Plumber Experience form to the Prov registration. Graduates of an approved Utah trade program stay in pending status until their school authorizes them to proceed, and out-of-state trade program candidates also attach official transcripts.

Where you test. Prov runs 25 written-exam testing centers across Utah, from Cedar City to Logan to West Jordan. Practical exams are given only at three of those sites: Salt Lake Community College's Redwood Campus in Salt Lake City, Ogden-Weber Technical College in Ogden, and Dixie Technical College in St. George. Online reschedules and cancellations are free up to 3 days before the exam date; after that the exam fee is forfeited.

What the Journeyman Theory exam actually tests. The 100-question exam weights drain, waste and vent work heaviest at 20 questions, followed by water supply at 15, indirect and special waste at 10, plumbing math at 9, plumbing safety at 9, and smaller blocks on fuel gas, water heaters, plumbing fixtures, pipe and fittings, hydronics, plumbing drawing, structural penetration and insulation, and basic valves. The Residential Theory exam swaps in a fire sprinkler section and trims a few of those categories, but keeps drain, waste and vent and water supply as the two heaviest blocks.

Remote written testing. Prov is authorized to proctor the written theory and law and rule exams remotely through Examroom.ai, for any candidate whose computer meets the minimum camera, browser and internet requirements, not only out-of-state applicants. The practical exam still has to be taken in person at one of the three Utah practical sites.

For how the national testing vendors differ in scheduling and rescheduling, see our guide to scheduling a contractor exam with PSI, Prov, or Pearson VUE.

Fees, Renewal and Continuing Education

Every figure below is set by DOPL or Prov and can change, so confirm it on the current form before you pay.

Renewal cycle. Utah plumbing licenses renew by November 30 of even years. DOPL emails a renewal notice 90 days before expiration; fees are non-refundable. Working after a license expires is unlawful conduct under Utah Code 58-1-501 and 58-1-502.

Continuing education. Each two year cycle requires 12 hours of approved CE: at least 8 hours of core education, and the other 4 either core or professional (R156-55c-304). Core topics include the adopted International Codes and Utah amendments, the Americans with Disabilities Act, medical gas and NFPA 13D and 54, hydronics and wastewater treatment, and OSHA training. Professional topics include energy conservation, management training, new technology, plan reading, lien laws and government regulations.

Licensed in Another State: Endorsement, Not Reciprocity

DOPL's plumber pages offer licensure by endorsement, not reciprocity. Each plumber license has its own endorsement map on DOPL's site showing which states DOPL treats as equivalent.

If your state is on the map, send DOPL a Verification of Licensure from your home board showing at least one year of active licensure in good standing. Master Plumber applicants by endorsement still pass the Utah Master Plumber Law and Rule exam at 75 percent or greater.

If your state is not on the map, you meet the Utah requirements above, and out-of-state hours may still count when your home jurisdiction verifies them.

A Plumber License Is Not a Plumbing Contractor License

You can hold a Utah Master Plumber license and still not be able to contract for plumbing work in your own company's name. To bid and contract, the business needs a contractor license in the right classification. DOPL lists two for plumbing among its general contractor classifications:

• P200, General Plumbing Contractor
• P201, Residential Plumbing Contractor

The statute ties each one to a master credential. Under Utah Code 58-55-302(1)(e)(v), a residential plumbing contractor must be a licensed master plumber or master residential plumber, and a plumbing contractor must be a licensed master plumber. DOPL's current contractor application (v20260327) says it in one line: electrical and plumbing classifications require the qualifier to hold the trade's Master License.

Notes on the contractor license

• Experience: a qualifier with two years on a Utah contractor license, a construction management degree, a Utah professional engineer license or a passed NASCLA commercial exam can satisfy it instead, per the DOPL general contractor page.
• Insurance: the certificate must name DOPL as certificate holder and cover your full scope of work for the entire time the license is active (R156-55a-302d), per the current contractor application.
• Fees: the $1.00 is the Electronic Reference Library surcharge. Processing fees are non-refundable. An unincorporated applicant pays $20 more for each owner holding less than 8 percent.
• Registrations: a business entity registers with the Utah Division of Corporations and holds a federal EIN.
• Financial responsibility: the application asks about judgments, liens, tax liens and child support delinquencies in the last eight years and bankruptcy in the last seven, for the applicant, the proposed qualifier and every owner and officer. A bond may be required before the license issues (Utah Code 58-55-306 and R156-55a-602).
• Specialties: a contractor may add up to three specialty trade classifications.
• Timing: DOPL's contracting FAQ says it cannot promise a processing time, and asks applicants to call if they hear nothing after four weeks.

For how Utah compares nationally, see contractor bond requirements by state and contractor insurance requirements by state.

The Qualifier Rules in Utah's Own Words

Utah Code 58-55-304 lets DOPL license a business entity only through an individual qualifier. The qualifier must be an owner, officer or manager who exercises material authority over the contracting business: making the substantive technical and administrative decisions on licensed work, handling hiring, discipline and direction of employees, and holding no other job that conflicts with those duties.

Utah Admin. Code R156-55a-304 puts numbers on that authority:

• Paid time: the qualifier is paid for at least 12 hours of work per week for the licensee. If all owners and employees together work fewer than 50 hours a week, the minimum can drop, but never below 20 percent of the total hours worked.
• Owner qualifiers: pay may take the form of profit distributions or dividends, but only with at least 20 percent ownership of the licensee.
• Officer or manager qualifiers: the rule states that pay "shall be in the form of W-2 wages."
• Several companies: a qualifier may not serve more than three licensees at one time unless the qualifier proves material authority over each business and the Commission and the Division grant written approval.

DOPL's contractor application turns that rule into a checkbox. On the Qualifier Affidavit, under "Select Qualifier's Business Entity Position," there are exactly two options: Owner of at least 20% or W-2 Employee in Management Position. There is no third box.

DOPL's contracting FAQ treats an arrangement in which a company contracts on a license held by someone outside the company as two class A misdemeanors: aiding and abetting for the license holder, and contracting without a license for the company. The only legal way to work under a license is as an officer or W-2 employee of the licensed contractor.

The statute also carries a reward for a clean record. Under Utah Code 58-55-304(5)(c), a plumbing business entity that has kept its license for five consecutive years without violations may meet the qualifier requirement at renewal by recording an active employee's name and license number from the trade, unless more than 50 percent of its ownership changed hands during those five years.

The qualifier angle for a company owner. That is what a qualifying agent is: the licensed master plumber whose credential your P200 or P201 stands on, working inside your company as an owner or a full time W-2 employee who actually supervises the work. If you have the crews and the jobs but no master plumber on staff, our team places qualifying agents as W-2 employees in exactly the role Utah's form describes: start at hire a qualifying agent, or look at contractor qualifier services built for exactly this gap. Before signing any arrangement, read can a qualifying agent be a 1099 contractor.

If you hold the master license yourself and want to understand the role from the other side, see become a qualifying agent.

When Your Master Plumber Leaves

Utah gives you a clock, and it is short. DOPL's contracting FAQ says that when a qualifier leaves a licensed contractor, both the qualifier and the licensee must notify DOPL in writing within 10 days of the last day of employment. The licensee then has 60 days from that date to replace the qualifier.

The statute sets the consequence. Under Utah Code 58-55-304(6) and (7), if notice is given, the license stays in force for 60 days after the qualifier's last day, and the statute's own text says it "shall be automatically suspended" if no replacement qualifier is in place by then. A licensee that never sends the notice can face immediate suspension on a finding of good cause.

DOPL adds the point every plumbing company owner should keep in mind: the license stays with the company; it does not belong to or travel with the qualifier. Build the plan before you need it: the contractor qualifier contingency plan.

The Licensing Steps in Order

1. Register as an apprentice. Your employer signs the Verification of Supervision form; file with the $116 fee.
2. Choose your track. Residential (432 classroom hours and 6,000 hours) or unlimited (576 classroom hours and 8,000 hours), or an experience only route.
3. Log hours carefully. No more than 3,000 hours count per 12 months, all under licensed supervision.
4. Create a UtahID, then register with Prov. Attach the Verification of Plumber Experience form, wait for school authorization if you trained in Utah, and watch for the 3-day reschedule cutoff once you book.
5. Pass both exams, then apply with the $116 fee.
6. Earn master hours. 4,000 work and 4,000 supervisory hours as a journeyman (they may overlap), or 2,000 supervisory hours with an AAS degree.
7. Pass the Master Plumber Law and Rule exam at 75 percent, then apply for the master license.
8. Stand up the contractor license. Finish the 30 hours of pre-licensure education, pass the Utah Business and Law exam, secure the liability coverage and file for P200 or P201 with a master plumber qualifier.
9. Renew on time. Plumber licenses by November 30 of even years; contractor licenses by November 30 of odd years.

Frequently Asked Questions

Is Utah DOPL the same as Idaho DOPL? No. Utah DOPL is the Division of Professional Licensing in the Utah Department of Commerce. Idaho's Division of Occupational and Professional Licenses is a separate agency with its own plumbing board, exams and fees.

What does a Utah residential plumbing license cover? The plumbing trade limited to residential buildings, which Utah law defines as dwellings of up to four units. A residential master can qualify a P201 Residential Plumbing Contractor, but not a P200.

How long does it take to become a licensed plumber in Utah? About four years on the school route (576 classroom hours and 8,000 hours) or eight years on experience alone (16,000 hours). The residential journeyman runs about three years with schooling (6,000 hours) or at least six years without (12,000 hours). A master license adds 4,000 work and 4,000 supervisory hours as a journeyman, which may overlap, or 2,000 supervisory hours with an AAS degree.

Can I take the Utah plumbing exam before my hours are done? Usually not. DOPL's plumbing FAQ says on-the-job hours and school hours or grades must be met before you are approved to test. The one exception is the school route journeyman, who may test after the first semester of the fourth year and 6,000 hours (R156-55c-302b(4)(b)). Every candidate also now needs a UtahID and, since January 2026, the Verification of Plumber Experience form at registration.

Does Utah accept an out-of-state plumbing license? Often, by endorsement. Check DOPL's endorsement map for your license level and send a Verification of Licensure showing at least one year of active licensure in good standing.

What does it cost to get a Utah plumbing license? Board and vendor fees: $116 to DOPL, and $78 to $85 per exam to Prov depending on whether you test by computer or paper, plus $74 to renew. A P200 or P201 adds the contractor fees, courses and insurance.

Can one master plumber qualify more than one company? Up to three at one time under R156-55a-304; more needs proof of material authority over each business and written approval from the Commission and the Division.

Who can replace an old underground water line in West Valley City? For plumbing work inside a building, hire a P200 or P201 contractor and check the license on DOPL's verification search. For a water line running farther out toward the street or a city meter, ask the West Valley City building department or public utilities office where the licensed trade's scope ends and the city's own easement work begins; Utah's own code does not spell out a fixed distance, so do not rely on one.

Do I need a Utah plumber license to work on my own home? Homeowner work on your own residence is treated differently from contracting for others. Confirm with DOPL and your local building department before assuming an exemption.

Where do I take the practical exam if I live near Ogden? Ogden-Weber Technical College, one of three sites in Utah where the Utah Plumber Practical is given; the other two are in Salt Lake City and St. George.
