Dreaming of a stable, in-demand career with strong earning potential? Becoming a licensed plumber in Oregon is a smart move—but it’s not as simple as picking up a wrench. If you’re asking “How to get a plumbing license in Oregon?”, you’re not alone. Thousands of aspiring tradespeople search this every year. The good news? With the right guidance, you can navigate Oregon’s licensing process smoothly and legally work on residential and commercial plumbing systems. Let’s break it down—clearly, accurately, and step by step.
What Are the Basic Requirements to Get a Plumbing License in Oregon?
Before you even think about applying, Oregon’s Construction Contractors Board (CCB) and the Oregon Health Authority (OHA)—which oversees plumbing regulation—require you to meet specific criteria. Unlike many states, Oregon does not issue a “statewide plumbing license” through a single agency. Instead, licensing is local, with state-level oversight for certain certifications.
Key prerequisites include:
Be at least 18 years old
Have a high school diploma or GED
Complete required training hours (varies by license level)
Pass a criminal background check
Work under a licensed plumber during apprenticeship
💡 Expert Insight: According to the U.S. Bureau of Labor Statistics (2024), employment of plumbers in the Pacific Northwest is projected to grow 8% through 2030—faster than the national average—thanks to aging infrastructure and new construction in cities like Portland, Eugene, and Bend.
Step-by-Step: How to Get a Plumbing License in Oregon
Oregon doesn’t have one universal plumbing license. Instead, you’ll typically pursue one of two paths:
Most plumbers start here. Oregon relies on local jurisdictions (like Multnomah County or the City of Salem) to issue plumbing licenses. However, the Oregon Health Authority (OHA) administers the state-level Journeyman and Master Plumber exams.
Even after passing the state exam, you must apply for a local plumbing license in the city/county where you work.
Example: Portland Bureau of Development Services requires a separate application and fee (~$150–$300).
Step 6 (Optional): Become a Master Plumber
After 2+ years as a journeyman, you can sit for the Master Plumber exam ($130 fee).
Required if you want to pull permits independently or own a plumbing business.
How Much Does It Cost to Get a Plumbing License in Oregon?

Do You Need a CCB License Too?
Yes—if you’re running your own plumbing business.
The Oregon Construction Contractors Board (CCB) requires anyone bidding, contracting, or advertising plumbing services to hold a CCB license. This is separate from your journeyman/master plumbing license.
You must pass the CCB test (business law & practices)
Provide proof of general liability insurance ($50k minimum)
Pay a $60–$200 licensing fee (based on business type)
⚠️ Warning: Working without a CCB license when required can result in fines up to $5,000 per violation.
Common Mistakes to Avoid
❌ Assuming one license works statewide → Local permits are mandatory.
❌ Skipping the apprenticeship → Oregon requires documented hours.
❌ Confusing CCB with plumbing certification → Both may be needed.
❌ Not studying the Oregon-specific code amendments → The state modifies the UPC.
A: Yes! Oregon accepts reciprocity for journeyman licenses from states with comparable standards (e.g., Washington, California). You still need to pass Oregon’s exam and meet local requirements.
Q2: How long does it take to become a licensed plumber in Oregon?
A: Typically 4–5 years through an apprenticeship. Accelerated paths exist but are rare and require documented prior experience.
Q3: Do I need a plumbing license for minor home repairs?
A: If you’re a homeowner working on your own primary residence, you may pull permits without a license. But if you’re paid to do plumbing—even for a friend—you need proper licensing.
Q4: Is the Oregon plumbing exam hard?
A: It’s challenging but passable with prep. The 2024 pass rate was 68% for first-time journeyman test-takers. Use OHA’s official study guide and practice tests.
Q5: Can I work as a plumber while waiting for my license?
A: Only as an apprentice under direct supervision of a licensed journeyman or master. Independent work is illegal.
Q6: How often do I need to renew my plumbing license?
A:Every 2 years. Renewals require proof of continuing education (4–8 hours) and updated insurance.
