Licensed Plumber in Oregon: How to Verify Before You Hire

CheckLicensed Editorial Team

Oregon plumbers require licensing at two levels: the plumbing business must hold a CCB license through the Oregon Construction Contractors Board (ccb.oregon.gov), and individual plumbers must hold a state plumbing license through the Oregon Building Codes Division (oregon.gov/bcd). This guide explains both requirements, how to verify a plumber's credentials before hiring, and what the $15,000 bond requirement covers.

Does Oregon require plumbers to be licensed?

Yes. Oregon requires plumbing contractors to hold a CCB license through the Oregon Construction Contractors Board, and individual plumbers must hold a plumbing license issued by the Oregon Building Codes Division (oregon.gov/bcd). Both are required independently — a licensed business using unlicensed plumbers, or a licensed plumber working for an unlicensed company, are both violations of Oregon law.

Oregon's plumbing licensing is administered through the BCD, which sets exam requirements, continuing education standards, and license classifications. The plumbing program covers drain, waste, vent, water supply, gas piping, and specialty plumbing systems. Each area of work is subject to licensing and permitting requirements enforced by local building departments in coordination with the state.

Oregon's CCB, with over 40,000 licensed contractors, provides a robust consumer protection layer on top of individual plumber licensing. Both databases should be checked before you hire.

Where do I verify an Oregon plumber's license?

Verify the plumbing contractor's business license at ccb.oregon.gov and verify individual plumber licenses through the Oregon Building Codes Division at oregon.gov/bcd. Both databases are searchable by name and license number. Confirm that both the business and the individual plumber show active status with current expiration dates.

The CCB lookup also displays the contractor's bond status. A lapsed bond means you lose the financial protection backing the license even if the license number is technically still active. Check bond status as a separate step in the CCB lookup.

Ask the plumber for both license numbers — the CCB number and the BCD plumbing license number — before authorizing any work. A licensed plumber will have both available without hesitation.

What plumber license types exist in Oregon?

Oregon's Building Codes Division issues plumbing licenses for apprentice plumbers, journeyman plumbers, and master plumbers. Apprentices work under direct supervision of journeymen or masters. Journeyman plumbers are fully licensed for standard plumbing work. Master plumbers hold the highest qualification and can supervise jobs, pull permits, and take on the full range of plumbing projects. Gas piping work may require a separate gas fitting endorsement.

For most residential and commercial plumbing projects, the supervising plumber must hold at minimum a journeyman license, and the contracting entity must hold a CCB license. Confirm which license classification applies before work begins.

What bond and insurance must Oregon plumbers carry?

Oregon requires residential plumbing contractors to carry a $15,000 surety bond through the CCB. The bond is a consumer protection mechanism: if the contractor abandons your project, performs work that fails inspection, or causes damage they refuse to remedy, you can file a claim through the CCB's dispute resolution process backed by the bond amount. The CCB has a formal complaint and arbitration process specifically for these situations.

Plumbing contractors must also carry general liability insurance and workers' compensation. The Insurance Information Institute reports that water damage and freezing claims are among the most common and costly homeowner insurance claims — faulty plumbing work is a significant contributor. Liability insurance provides a recovery path when plumbing work causes property damage.

Request certificates of insurance and verify them with the carrier directly, not just with the contractor.

What are the penalties for unlicensed plumbing in Oregon?

Oregon can fine unlicensed contractors up to $5,000 per violation. The CCB and BCD both have enforcement authority and actively investigate complaints and referrals. Work performed without permits typically fails inspection and requires a licensed plumber to redo it — at your expense as the property owner. In Oregon, unpermitted plumbing work is a disclosure obligation in real estate transactions and can complicate or derail home sales.

Homeowners who hire unlicensed plumbers have no access to the CCB's bond claim and dispute resolution process. Once unlicensed work is performed, your options for recovery narrow significantly. Prevention — verifying credentials before hiring — is the only reliable protection.

What else should I check before hiring an Oregon plumber?

After confirming both licenses — CCB at ccb.oregon.gov and individual plumber at oregon.gov/bcd — verify that permits will be pulled before work begins. Confirm insurance with the carrier. Get a written scope and quote before any payment. Do not pay in full until the work passes inspection and you have a copy of the signed permit card.

Oregon's dual-licensing system provides strong consumer protections. Taking five minutes to run both checks before hiring a plumber makes the full weight of those protections available to you.
