How to Start a Plumbing Business in Oregon: Licenses, Costs & Insurance

Oregon plumbing businesses need two layers of licensing. Each plumber needs an individual journeyman plumber license from the Building Codes Division (BCD), under the State Plumbing Board. The business needs a BCD plumbing contractor license plus a Construction Contractors Board (CCB) license, which carries its own bond and insurance requirements.

This guide is for plumbers moving into ownership and for owners setting up a plumbing company in Oregon. Forming a business, or holding a worker’s license, doesn’t by itself give the company the right to contract for plumbing work.

Get the journeyman license, the plumbing contractor license and a CCB license

• Journeyman plumber: you apply to BCD with experience verification forms from each employer, showing experience in the work categories required by Oregon rule (OAR 918-695), plus proof of apprenticeship or classroom training and a high school diploma or GED. Once approved, you schedule the licensing exam (BCD journeyman plumber license). Oregon also has limited specialty plumber licenses, such as water heater installation.
• Plumbing contractor license: state law says nobody may work, advertise or purport to be a plumbing contractor without a plumbing contractor license, and the contractor license alone doesn’t let you do journeyman work (ORS 447.040). You apply to BCD with the Contractor/Business License Application, listing your CCB license and Secretary of State registration (BCD contractor licenses).
• CCB license: Oregon construction contractors also need a Construction Contractors Board license with the right residential or commercial endorsement.

Maximum fees set in state law (ORS 693): up to $100 for a journeyman plumber application and $50 a year to renew; up to $150 for a plumbing contractor application and $150 a year to renew; $25 a year for continuing education. CCB fees and exam fees are separate. Check current BCD and CCB fee schedules before you pay.

Write down the services your license will cover and who is responsible for supervising the work. Ask separately about specialty work such as medical gas, backflow testing, gas piping, septic systems or well work. Don’t assume every job involving pipe falls under the same license. Plan what happens if the person whose license the company relies on leaves.

Set up the business in the same name you will license

Choose the ownership structure before you finish license applications, insurance and banking. An LLC is an option, not a substitute for plumbing licensing. Our Oregon LLC guide explains filing choices and costs so you can compare filing yourself with optional help.

Use the same legal name, and any registered trade name, on license records, estimates, insurance certificates and payment accounts. Decide who can sign contracts, approve supplier purchases and use the bank account. If there are several owners, put licensing and money responsibilities in your ownership agreement.

Use the Oregon business requirements checklist for general setup, such as state tax accounts and registrations. Ask your city or county about local business licenses, zoning and storage rules for your office or shop, even if it’s in your home.

Open a separate business bank account and keep job-by-job records before you take deposits. Get an EIN when you need one through the IRS’s free EIN application. Track materials, labor, permit fees and customer payments separately, so unpaid invoices don’t look like cash in the bank.

Arrange plumbing liability coverage and workers’ compensation

For coverage choices, licensing limits and quote preparation, see our Oregon plumbing insurance guide.

CCB bond and insurance amounts depend on your endorsement. According to the CCB endorsement chart, a Residential Specialty Contractor needs a $20,000 bond and $300,000 per occurrence liability insurance. A Residential General Contractor needs a $25,000 bond and $500,000 per occurrence. Commercial endorsements have their own amounts (CCB endorsement chart).

Oregon requires employers with one or more subject workers to carry workers’ compensation (Oregon DCBS).

Tell the insurer about drain cleaning, digging, gas piping, commercial work, subcontractors and the tools you keep in your van. Ask about completed work, water-damage claims, exclusions, commercial auto and equipment theft. Make sure coverage is active before you book the work; a quote request isn’t a policy.

Check permits and site access before promising a completion date

Who issues plumbing permits and does inspections depends on where the job is. Ask the city or county building department, or BCD, before you start.

• Water heaters and fixture swaps: check whether the actual job needs a permit and inspection instead of assuming replacements are exempt.
• Repiping and remodels: plan inspections before walls are closed, and agree who repairs drywall and finishes.
• Sewer and underground work: call for utility locates before digging, and find out whether street or utility approvals are involved.
• Apartments, condos and managed buildings: agree on access, water shutoff notices, work hours and any paperwork the property manager needs.

Write down existing damage and access limits before you start. Don’t promise a permit waiver or an insurance payout you haven’t confirmed.

Budget for a Oregon service operation, not just the license

Build the budget around the services you’ll open with: repairs and replacements, drain work, remodels or commercial subcontracting. Price the actual equipment and insurance before committing to a van or taking on debt. You can often rent specialty cameras and drain machines at first if the jobs justify it.

Example launch cash plan—not surveyed Oregon prices

Category	Example allowance
Setup and first insurance payments	$3,000 placeholder for applications, exams, company setup and first insurance payments; replace it with your actual fees and quotes.
Tools and opening parts	$5,000 to fill gaps in an existing toolkit and stock common repair parts.
Vehicle preparation	$2,000 for a suitable vehicle you already own; doesn’t include buying a van.
Working cash	$8,000 assumed reserve for supplier bills, fuel and overhead until customer payments arrive steadily.
Example total	$18,000, not counting a vehicle purchase, employee payroll, major specialty equipment or household living costs.

Plan weekly cash needs, including a late invoice or a callback you can’t bill. New businesses may not meet a lender’s time-in-business or revenue rules. Compare total repayment, fees, payment schedule and personal guarantees before you borrow; approval isn’t guaranteed.

Price the job, document the scope and collect payment

Set a clear service-call or diagnostic fee. A short repair can still involve driving, picking up parts, paperwork and a return trip, so the wage you want isn’t the same as your billing rate. The national plumbing pricing example shows how the same monthly cost target leads to different rates at different numbers of billable hours.

Before work starts, write down the approved repair, included materials, who pulls the permit, what restoration isn’t included and how payment works. Get approval for extra work you find after opening a wall or scoping a drain. Have Oregon contract and notice rules reviewed before you adopt standard paperwork.

Sort out sales tax before you copy an invoice template. States treat contractors differently: in some, you pay tax on materials you buy; in others, you charge tax on some jobs. Ask the Oregon tax agency or your bookkeeper how it applies to your repair, installation and new-construction work. Our Oregon business setup guide covers state tax registration.

Check your payment system’s fees, payout timing and dispute process. Keep the customer’s approval, before-and-after photos and completion notes with the invoice. For commercial jobs, plan for progress billing and retainage separately from pay-when-done home service calls.

Win local work before adding a second truck

Pick a service area you can cover profitably, and make your services and hours clear. Build referral relationships with property managers, remodelers and other trades. Ask happy customers for honest reviews, and track which inquiries turn into paid jobs, not just which ads make the phone ring.

For managed properties, prepare a short packet with your current license, insurance certificate, contacts and invoicing details. Agree who can approve an emergency repair and what happens if the repair costs more than first approved.

Hire for a specific bottleneck. Check the worker’s license or registration, required supervision, payroll setup and workers’ comp before the first shift. Count training, travel, unbilled hours and extra equipment in the cost of growing.

Our skilled-trade and AI construction research is useful background, but announced projects don’t prove demand for your particular service. Build your first operation around customers you can reach and work you’re licensed and equipped to do.

Oregon plumbing startup questions

Is a CCB license enough to do plumbing in Oregon?

No. Plumbing also needs a BCD plumbing contractor license for the business and licensed journeyman plumbers to do the work.

Can a plumbing contractor license holder do the plumbing personally?

Not on that license alone. State law says the plumbing contractor license doesn’t authorize journeyman work, so the person doing the work needs a journeyman license.

Which CCB endorsement do I need?

It depends on the type of structure. Residential endorsements cover homes and small commercial work, and commercial endorsements cover larger commercial projects. Some contractors need both.
