Do I need an Oregon state contractor license to work on my house?

Oregon runs one of the strictest contractor-licensing regimes in the country, administered by the Oregon Construction Contractors Board (CCB). Under ORS 701.021, any person or business that contracts to perform construction work in Oregon must hold an active CCB registration before bidding, advertising, or starting work. The threshold is effectively zero for any work involving electrical, plumbing, mechanical, or structural systems, and the small-repair carve-out tops out at $1,000 in total compensation including labor and materials (ORS 701.010(7)). That means a $1,200 fence repair or a single-day deck-board replacement falls under the registration mandate the moment it crosses the threshold. Beyond CCB registration itself, plumbing work requires a separate Oregon Building Codes Division (BCD) plumbing license under ORS 693, and electrical work requires a BCD electrical license under ORS 479 — neither is satisfied by CCB alone. Penalties for unregistered contracting are stiff. ORS 701.992 makes a knowing violation a Class A misdemeanor, and the CCB can issue civil penalties up to $5,000 per offense plus restitution. Homeowners hiring an unregistered contractor lose access to the CCB's complaint-resolution process, which is the primary consumer-protection mechanism in Oregon — claims against a registered contractor's bond (residential bond is currently $20,000 to $80,000 depending on endorsement) are not available against unregistered actors. Always verify status directly at search.ccb.state.or.us before signing. The search returns the contractor's CCB number, expiration date, bond status, insurance coverage, license endorsement (residential general, commercial, locksmith, etc.), complaint history, and any pending suspensions. Verify on the day you sign — registrations expire every two years and a lapsed contractor is functionally unregistered. We also recommend confirming workers' comp coverage through the Oregon Workers' Compensation Division because the CCB record alone doesn't always reflect a current SAIF or carrier policy.
