What Is Prevailing Wage in Oregon: Rates, Payroll, and Penalties

Prevailing wage in Oregon is the minimum hourly compensation, including fringe benefits, that contractors and subcontractors must pay workers on public works projects when the total contract price is more than $50,000. The Bureau of Labor and Industries (BOLI) publishes these rates by trade and by county, and updates them on a quarterly schedule.¹ The goal is straightforward: bids on taxpayer-funded construction compete on quality and efficiency, not on who will pay workers the least.

Which Projects Are Covered

Oregon’s prevailing wage law applies to “public works” as defined in ORS 279C.800. That includes construction, reconstruction, major renovation, painting, and demolition carried out by or for a public agency, or financed in whole or in part with public funds.² A private contractor hired to build a county library or renovate a state office is covered when public money pays for the work.

The law only applies once the total contract price exceeds $50,000, measured against the full project value rather than individual subcontracts.³ Splitting a larger job into smaller contracts to stay under the number doesn’t work and creates legal exposure for everyone involved.

One notable boundary: privately owned residential construction that predominantly provides affordable housing falls outside prevailing wage requirements when at least 60% of the units serve occupants earning no more than 60% of area median income (80% for owner-occupied units).⁴

How Rates Are Set and Which One Applies

BOLI sets the prevailing rate for each trade classification and publishes it by county in the Prevailing Wage Rate (PWR) publications. An electrician in Multnomah County will see a different listed rate than an electrician doing the same work in Josephine County, because the rates reflect local labor market conditions.

Rates are generally updated four times a year, on January 5, April 5, July 5, and October 5.¹ The rate that controls a project is the one in effect on the date the project was first advertised for bid. If BOLI publishes a new schedule mid-construction, the project stays on the original rate. That’s why picking the right county table and trade classification at the start of the job matters so much; errors there turn into underpayments and penalties later.

What a Prevailing Wage Payment Includes

Every listed rate has two parts: a base hourly rate and a fringe benefit rate. The base is cash in the paycheck. The fringe covers items like health insurance and retirement contributions. The combined value must meet or exceed the published total for every hour worked on the project.

Employers can satisfy the fringe portion by paying into qualified health or pension trust funds, or by adding the fringe amount directly to the worker’s hourly cash wages. If the benefits provided cost less than the required fringe rate, the shortfall must be paid out as additional taxable wages. The total compensation is what has to hit the published number.

Overtime Pay Is Calculated Differently Than You’d Expect

Overtime on prevailing wage projects is one and a half times the base hourly rate only. The fringe benefit amount is not part of the overtime multiplier.⁵ If a listed base rate is $40 and the fringe is $15, overtime pay is $60 per hour ($40 × 1.5), with the $15 fringe obligation still owed on top. Contractors who assume overtime applies to the full combined rate end up overpaying, and workers who assume the opposite can miss underpayments.

When Davis-Bacon Also Applies

Projects funded with both state and federal money trigger two sets of prevailing wage rules: Oregon’s law and the federal Davis-Bacon Act, which applies to federally funded or assisted construction contracts over $2,000.⁶ On non-residential projects covered by both, Oregon requires contractors to pay the higher of the two rates for each trade classification.⁷

That comparison runs trade by trade. One classification on a project might have a higher state rate while another has a higher federal rate. Contractors bidding dual-funded work need both schedules in hand before pricing the job.

Apprenticeship Utilization on Larger Projects

On public works contracts carried out by qualifying agencies (state agencies, public universities, and community colleges using state treasury funds), apprentices must perform at least 12% of total work hours in apprenticeable occupations once the contract price exceeds $3,000,000. The same 12% rule applies to any subcontract worth $750,000 or more.⁸

Missing the target has a direct cost. The qualifying agency reduces the contractor’s payment by $15 for every hour of apprentice work that fell short of the requirement: multiply total work hours by 12%, subtract actual apprentice hours, and multiply the gap by $15.⁸ On a large job, the deduction adds up quickly.

Apprentices must be registered with BOLI’s Apprenticeship and Training Division or the federal Bureau of Apprenticeship and Training. They can be paid a percentage of the journey-level base rate according to their program step, but only while performing work within their program standard and the correct apprentice-to-journeyworker ratio. An apprentice working outside that ratio must be paid the full journey-level prevailing wage.⁸

Certified Payroll Reporting

Contractors and subcontractors on covered projects must file certified payroll statements with the public agency overseeing the work, using BOLI’s Form WH-38.⁹ Each statement is a sworn declaration that every worker was paid at least the applicable prevailing wage.

Under ORS 279C.845, the statement must include each worker’s name and address, correct trade classification, rate of pay, daily and weekly hours worked, and gross wages for the reporting period. Statements covering each week workers were on the project are due once a month, by the fifth business day of the following month.¹⁰ Late or incomplete filings draw attention from the contracting agency and can start an investigation.

Penalties for Non-Compliance

A contractor or subcontractor found to have intentionally failed or refused to pay the prevailing rate is barred from all public works contracts in Oregon for three years. BOLI publishes a public list of debarred contractors, and the ban extends to any firm in which a debarred contractor holds a financial interest.¹¹

Debarment comes on top of liability for the unpaid wages themselves and possible additional damages. On dual-funded projects, the federal government can impose its own parallel three-year debarment under Davis-Bacon and require back wages plus liquidated damages.¹² A contractor shut out of both state and federal public work for three years is, for most firms, out of business.

Recovering Unpaid Wages

Workers who weren’t paid the full prevailing rate have several ways to recover. The most common is a complaint to BOLI’s Wage and Hour Division, which investigates by pulling payroll records and comparing wages actually paid against the applicable rate schedule.¹³ Workers can also file a civil suit directly, and union members can pursue the claim through a grievance.

The statute of limitations for a prevailing wage claim is six years, a long enough window to catch underpayments that aren’t obvious at the time.¹⁴ One carve-out: overtime claims shrink to just 90 days after project completion if the contractor properly posted the required statutory notice at the jobsite. If you worked a public project and think you were shortchanged, check your pay stubs against the published PWR rate for your trade and county. That one comparison usually tells you whether you have a claim worth pursuing.
