How to get a plumber license in Oregon
State law and licensing-board sources · Last reviewed October 11, 2026
Journeyman level 7,700 hours on the job + state exam What's a journeyman?
Oregon licenses plumbers through the Building Codes Division (BCD). Under state law you can't work as a journeyman plumber without a journeyman plumber (JP) license, and an apprentice plumber must be in a state-registered apprenticeship and work under a licensed journeyman. The usual route is a four-year registered apprenticeship, then a 4-hour, 64-question open-book exam for the JP license. [1][2][3]
New to the trade?
Starting from zero in Oregon
In Oregon, plumbing is done by licensed journeymen and by apprentices: state law bars a plumbing contractor from letting anyone work as an apprentice plumber unless they meet the state apprenticeship law. So your first step is to apply to a registered plumbing apprenticeship; BOLI's plumber program list shows each program and whether it's taking applications. Most Oregon programs ask that you be 18 and have a high school diploma or GED. [1][7][8][18]
High school diploma or GED
Required. Oregon's statewide minimum standard for plumber apprenticeships, which every registered plumbing program must meet, calls for a high school diploma or GED. State rule also requires a diploma, GED or international equivalent (or a college degree) before you take a BCD license exam. [5][8][19]
Still in high school?
Plumbing programs register apprentices only at 18, so BOLI points younger students to pre-apprenticeship programs Its list includes youth programs such as Benson Polytechnic High School's construction technology program. In school, the Oregon Department of Education's career and technical education (CTE) area Industrial and Engineering Systems includes construction, and you can look up approved CTE programs by school. Many let you earn college credit in high school. We found no Oregon rule that counts high school classes toward the JP license. [3][8][20][23][24][25][26]

Who needs a plumbing license in Oregon
State law says you may not work as a journeyman plumber without a journeyman plumber license. An apprentice plumber may work at the trade under the supervision of a licensed journeyman plumber. Plumbing contractors may not let unlicensed people work as journeymen or let anyone work as an apprentice who doesn't meet Oregon's apprenticeship law.
The Building Codes Division issues the journeyman plumber (JP) license and three limited plumbing licenses: water-treatment installer (WTI), residential water-heater installer (WHI), and solar heating and cooling installer (STL). Its list of individual licenses has no master plumber license (state law lets the State Plumbing Board create a supervising plumber license by rule, but BCD lists none). Call BCD licensing at 503-373-1268. [1][2][4]
Qualifying for the journeyman plumber license
BCD accepts any of three routes:
- A certificate of completion from a registered four-year apprenticeship, or a referral letter from the registered training committee or a board-approved training program.
- At least 576 hours of classroom training (math and science, codes, drainage, water systems, blueprint reading, seismic restraints and more) plus 7,700 hours of on-the-job experience: 3,850 residential and 3,850 commercial, with minimums in each work category.
- Twice the experience in each category (7,700 residential and 7,700 commercial hours), gained lawfully under a license that covers the scope of an Oregon JP.
BCD counts no more than 2,000 hours of experience a year, and only lawful experience counts. [2][3][5]
The exam, fees and renewal
The JP exam is 4 hours, 64 questions and open book, and BCD says the passing score for all its license exams is 75%. After BCD approves your application it mails a Letter of Authorization; you schedule with your test site and must test within 60 days. Results take about two weeks, and after a failure you wait 30 days to retake it.
The JP application fee is $100 and is nonrefundable. Each three-year cycle you need 24 hours of approved continuing education, including 4 hours of code change. The rule also adds a 4-hour Oregon rule and law course after dates set in a BCD table, so confirm your hours with BCD. BCD lists April 1, 2029, as the next renewal date for all JP licenses. [2][4][5][6]
Union and open-shop apprenticeships
Oregon's registered programs are listed by the BOLI Apprenticeship and Training Division, from Astoria to Klamath Falls and Pendleton. All of them must meet the statewide plumber standard: age 18, a diploma or GED, and at least 144 hours of related classes a year.
- UA Local 290 (Tualatin) is the union route. Its plumber standard runs 8,000 hours, starting at 40% of the journey rate.
- Area I Plumbers (Lake Oswego) is an open-shop program: four years, classes at Clackamas Community College, starting at 45% of the average journey wage.
If you're licensed in another state
Oregon has journeyman plumber reciprocity with Idaho and Montana only. You need a current license with no violations in the past three years, an apprenticeship equivalent to Oregon's four-year program, a passing score of 75% or better on that state's exam, 1,000 hours worked under the license, and no failed Oregon exam in the past two years. Apply with the Reciprocal Plumbing License Application ($100).
From other states, you can apply under the experience route above and take the Oregon exam. [3][13][14]
Plumbing businesses
A company that installs or repairs plumbing for others needs BCD's plumbing business (PB) license, which doesn't by itself let anyone work as a journeyman. Plumbing is also construction work that needs a Construction Contractors Board license. [15][16]
Steps to get licensed in Oregon
Join a registered plumbing apprenticeship
Apply to a BOLI-registered program. Once registered, you can work as an apprentice plumber under a licensed journeyman. [1][7]
Finish the hours and classes
Complete the four-year program: Oregon's equivalency rule counts 7,700 on-the-job hours, half residential and half commercial, plus 576 classroom hours. [2][3]
Apply to BCD for the JP license
Send the Journeyman Plumber License Application with your certificate of completion or referral letter from your training committee, or your experience verification forms, and the $100 fee. Applicants who take an exam must show a diploma, GED or college degree. BCD mails you a Letter of Authorization. [2][4][5][6]
Take the exam within 60 days
Schedule the 4-hour, 64-question open-book exam with your test site; you need 75% to pass. Results come by mail in about two weeks; after a failure you wait 30 days to retest. [2][4]
Renew on the three-year cycle
Complete 24 hours of approved continuing education, including 4 hours of code change, before you renew. [5]

Questions people ask
How long does it take to become a journeyman plumber in Oregon?
About four years. The usual route is a four-year registered apprenticeship; the equivalency route needs 7,700 on-the-job hours plus 576 classroom hours. Then you pass a 4-hour open-book exam. [2][3]
Can I work as a plumber's helper in Oregon without being an apprentice?
Oregon law provides for journeymen and apprentices, not helpers: you can't work as a journeyman without a JP license, a plumbing contractor may not let anyone work as an apprentice who doesn't meet Oregon's apprenticeship law, and apprentices work under a licensed journeyman. Ask BCD about any work outside these roles. [1]
