CCB License Requirement
Oregon requires a CCB license for anyone who, for compensation, arranges, offers to arrange, or performs construction work on real property. Residential and commercial licenses are separate endorsements.
Residential General Contractor Insurance
A residential general contractor must carry at least $500,000 per-occurrence general liability insurance and a $25,000 surety bond before the CCB will issue or renew a license.
Commercial General Level 1 Bond
A Commercial General Contractor Level 1 must post a $75,000 surety bond and carry $1 million per-occurrence and $2 million aggregate general liability insurance.
License Renewal Cycle
CCB licenses expire two years from the date of issuance and renew on a staggered biennial cycle. A contractor may not perform work while the license is expired, suspended, or inactive.
Unlicensed Contractor Consequences
An unlicensed contractor cannot bring a court action to collect compensation for construction work, and a homeowner may recover amounts paid to an unlicensed contractor.
Written Contract Threshold
Residential construction contracts over $2,000 must be in writing and include the contractor's CCB license number, the consumer notice statement, and the 3-business-day right to cancel.
Right to Cancel
The homeowner has 3 business days to cancel a residential construction contract. The notice must be printed in at least 10-point bold type and the period runs from signing.
Down Payment Limit
A contractor may not demand or receive more than one-third of the contract price as a down payment before work begins on a residential project.
Lien Filing Deadline
A construction lien must be filed within 75 days after the contractor's last day of work. A Notice of Right to Lien must be given within 20 days of first furnishing labor or materials.
Prompt Payment Statute
Oregon requires owners to pay contractors within 30 days of a proper invoice and contractors to pay subcontractors within 7 days of receiving payment.
Fall Protection Threshold
OSHA fall protection is required at 6 feet for general construction and 10 feet for scaffolding. Guardrails, safety nets, or personal fall arrest systems are acceptable controls.
Excavation Protective Systems
Excavations 5 feet or deeper require protective systems such as sloping, shoring, or shielding, and a competent person must inspect the excavation daily before workers enter.
Extension Ladder Slope
Extension ladders must be set at a 4:1 slope, extend 3 feet above the landing, and be secured at the top. Workers must never stand on the top two rungs.
Oregon Energy Code Testing
Oregon's energy code sets insulation, window U-factor, and air-sealing requirements, and blower-door testing is required for new dwellings to verify envelope tightness.
Structural Concrete Strength
Minimum compressive strength for structural concrete is typically 2,500 psi for foundations and 3,000 psi for slabs on grade, per ACI 318 and Oregon amendments.
Exam Passing Score
The residential general contractor exam is 100 questions with a 180-minute limit. A passing score is 70 percent overall and 70 percent in each section.
Continuing Education Requirement
Residential general and specialty contractors must complete 8 hours of CCB-approved continuing education per two-year renewal cycle, including 3 hours of laws and business practices.
License Number Format
A CCB license number is a six-digit number. Consumers can verify a contractor's license status, bond, and insurance through the CCB online search.
Workers Compensation Requirement
Workers' compensation coverage is required for all employers with one or more employees. Sole proprietors and corporate officers may be exempt but must file the appropriate exemption form.
Recovery Fund
The CCB's Residential Contractor Recovery Fund pays consumers who obtain a judgment against a licensed contractor that cannot be satisfied, subject to per-claim and per-contractor caps.
Statute of Repose
Oregon's statute of limitations for written contracts is 6 years. Construction defect claims are generally brought within 2 years of discovery, with a 10-year statute of repose.
Civil Penalty Amounts
The CCB may impose civil penalties of up to $5,000 per violation for unlicensed contracting and up to $1,000 per violation for other licensing violations.
Complaint Response Deadline
The CCB consumer complaint process requires the contractor to respond within 14 days. Failure to respond can result in a default order and license suspension.
Scaffold Requirements
Scaffold platforms must be fully planked with a 3-foot guardrail and a 4-inch toe board. Supported scaffolds must maintain a 4:1 height-to-base ratio.
Radon-Resistant Construction
Radon-resistant construction is required in designated counties and includes a soil-gas barrier, a vent pipe, and a junction box for a future fan.
Utility Locate Requirement
Call 811 at least 2 business days before digging. The locate request is valid for 10 business days and must be renewed if work extends beyond that period.
License Suspension Effect
A contractor whose license is suspended must stop all work, including work already under contract, until the suspension is lifted. Continuing to work is a violation subject to civil penalty.
Bond and Insurance Lapse
A contractor must maintain the required bond and insurance continuously. A lapse of more than 30 days may result in license suspension by the CCB.
Retainage Limit
Retainage on private commercial projects is limited to 5 percent of the contract price. On public projects the limit is 5 percent until substantial completion.

A written change order signed by the owner is required before performing work outside the original contract scope. Oral changes are unenforceable for price adjustments.
