Oregon’s prevailing wage law, administered by the Bureau of Labor and Industries (BOLI) under ORS 279C.800 through 279C.870, requires that workers on Oregon public works construction projects be paid at least the prevailing wage rate for their trade and locality. The law applies to public contracts for construction, alteration, or repair of public buildings or public works, the same basic trigger structure as federal Davis-Bacon, but with Oregon-specific rates and Oregon-specific compliance requirements that differ from both Davis-Bacon and Washington’s Prevailing Wage Act.
What Triggers Oregon Prevailing Wage
Oregon prevailing wage applies to public works contracts above $50,000. The definition of public works under ORS 279C is broad: it includes construction contracts with state agencies, political subdivisions (cities, counties, special districts), school districts, and public universities. It also applies to contracts for construction on publicly owned property, contracts funded in whole or in part with public funds, and contracts for construction of facilities that will be leased to a public body.
The public funding trigger is the most important consideration for private developers whose projects receive any public subsidy. A private multifamily project that receives urban renewal funds, Community Development Block Grant financing, or a public loan from a state or local economic development program may be subject to Oregon prevailing wage, even if the project is privately owned and operated, because the public funding component triggers the law.
Developers structuring Oregon projects with public financing components should consult with Oregon construction counsel before assuming prevailing wage does or doesn’t apply. The trigger analysis requires a specific review of the funding structure, the nature of the public body’s involvement, and the applicable exemptions.
How BOLI Sets Prevailing Wage Rates
BOLI conducts wage surveys of contractors working on public works projects in Oregon to establish prevailing wage rates by trade classification and by county. Oregon is divided into geographic regions with different rate schedules, Portland metro rates differ from Eugene, Salem, and rural Oregon rates. BOLI publishes updated rate schedules periodically, and the applicable rate for a specific project is determined by the location of the project and the trade classification of the work being performed.
Oregon’s prevailing wage rates include a base wage and a fringe benefit component, similar to the Davis-Bacon structure. Contractors who provide health insurance, retirement contributions, or paid leave can credit those benefits against the fringe benefit component of the prevailing wage obligation. Contractors who provide no fringe benefits must pay the full prevailing wage (base plus fringe) in cash.
The applicable rate schedule for an Oregon public works project must be incorporated into the contract documents and posted at the job site in a location visible to workers. The contract documents must also include the required BOLI-prescribed language notifying contractors and subcontractors of their prevailing wage obligations.
Certified Payroll Requirements
Oregon public works contractors must submit certified payroll records, weekly payroll records showing each worker’s name, trade classification, hours worked, hourly rates paid, and fringe benefit contributions, to the contracting agency for the duration of the project. The contracting public body is responsible for reviewing certified payrolls for compliance and reporting violations to BOLI.
The certified payroll obligation extends to every subcontractor on the project at every tier. A GC that fails to ensure its subcontractors submit certified payrolls, or that pays subcontractors using non-prevailing wage rates, faces liability for the subcontractors’ violations as well as its own.
BOLI conducts random audits and investigates complaints regarding prevailing wage violations. Penalties for violations include the difference between wages actually paid and prevailing wages owed, plus 25% of the underpayment as a penalty. Contractors found to have willfully violated Oregon prevailing wage law can be debarred from public works contracts in Oregon for up to three years.
Oregon vs. Washington vs. Davis-Bacon: The Key Differences
Oregon, Washington, and federal Davis-Bacon all have prevailing wage frameworks with the same basic structure, public works triggers, trade-specific rates, certified payroll requirements, but with important differences in rates, thresholds, and enforcement:
Threshold. Oregon’s threshold is $50,000. Washington’s Prevailing Wage Act applies to all public works regardless of amount (no minimum threshold). Federal Davis-Bacon applies to contracts above $2,000. Oregon’s $50,000 threshold means that small public works contracts escape Oregon prevailing wage while they would be covered under Washington and federal law.
Rate levels. Oregon’s prevailing wage rates are generally lower than Washington’s for comparable trade classifications, reflecting Oregon’s lower overall wage levels in the construction labor market. The differential is most pronounced in rural areas, where Oregon rates can be 20% to 30% below comparable Washington rates.
Projects with both state and federal funding. When an Oregon public works project receives both state and federal funding, both Oregon prevailing wage and federal Davis-Bacon may apply simultaneously. In that case, the worker must receive the higher of the two applicable rates for each classification. The compliance program must satisfy both requirements.
Practical Implications for Oregon Construction Projects
For private developers, the most actionable guidance is to conduct a public funding trigger analysis before closing on any Oregon development transaction that involves public financing. If prevailing wage applies, the construction budget must reflect prevailing wage labor costs, which on a Portland multifamily project can represent a 15% to 25% premium over market-rate non-prevailing wage labor in the most impacted trades.
For construction lenders financing projects with public funding components, the pre-closing due diligence should include a review of whether prevailing wage applies and whether the construction budget reflects the appropriate labor cost level. A project that is required to pay prevailing wages but that was budgeted at market-rate labor costs has a systematic budget deficiency that the monitoring program will identify, ideally before the loan closes rather than after construction begins.
