7 Mistakes to Avoid When Hiring a Contractor in Oregon
Most contractor disputes in Oregon are preventable. The same mistakes come up again and again — here's how to avoid every one of them.
Mistake #1 starts with not verifying the license. Check any Oregon CCB license in seconds.
Not verifying the CCB license
This is the most consequential mistake — and the easiest to avoid. Oregon requires every construction contractor to hold a valid CCB license. A license means the contractor is bonded and insured. Without it, you have no bond to claim against if work is abandoned or substandard, and no access to the CCB's complaint and mediation process.
Search the CCB license before any conversation about price or timeline. It takes 30 seconds. Confirm the license is Active, the bond hasn't expired, and the business name matches what the contractor told you.
Not getting a written contract
Oregon law requires written contracts for construction work over $2,000 — yet verbal agreements remain one of the most common sources of CCB disputes. A proper written contract should include the scope of work, specific materials, start and completion dates, a payment schedule tied to milestones, and a change order clause.
If a contractor resists putting the agreement in writing, treat it as a serious red flag.
Only getting one bid — or automatically taking the lowest
Get at least three bids for any significant project. Multiple bids help you understand what the project should actually cost and reveal whether any contractor is cutting corners or padding margins.
A bid significantly lower than the others is often a warning sign — not a bargain. It may indicate substandard materials, underpaid workers, or a contractor planning to add costs through change orders after work begins. The Oregon CCB notes that "a price too good to be true often turns into a construction nightmare."
Not checking references
Oregon does not require construction contractors to hold trade-specific training (unlike plumbers and electricians). This makes references more important, not less. Ask for contact details of past customers on similar projects.
Questions to ask: Was the work completed on time? Did the contractor return calls? Were there unexpected cost increases? How were problems handled? Look at examples of the contractor's work where possible — especially for visible finish work like tiling, painting, or cabinetry.
Paying the full amount upfront
Never pay the full contract amount before work begins, and never pay in cash. A reasonable deposit (typically 10-30% depending on project size) is normal. The remainder should be tied to project milestones: framing complete, rough-in complete, project complete.
Full upfront payment removes your leverage entirely. If something goes wrong, the contractor has every incentive to walk away. The surety bond on a licensed contractor's record provides some protection — but prevention is better. Write checks to the business name on the license, not to an individual's name.
Not checking complaint and disciplinary history
CCB Lookup shows license status, bond, and insurance data. But the official CCB database also contains up to 10 years of complaint history, civil penalties, and license suspensions — information that can reveal a pattern of problems.
Always check both: use CCB Lookup for license, bond, and insurance, then visit search.ccb.state.or.us to review complaint history. A contractor with multiple complaints or a recent suspension is a contractor to avoid.
Not planning the project before hiring
Contractors who start work with a vague scope are more likely to encounter disputes about what was agreed. Before you call anyone, define your project clearly: budget, timeline, specific materials and finishes you want, and what decisions you are willing to delegate.
Collect pictures of styles and finishes you like. Research brand names and models. Walk through a finished example with a potential contractor and point out what you like and don't like. The clearer your brief, the more accurate the bids — and the fewer surprises during construction. If significant changes arise during the project, document them in writing with a signed change order.
