Prevailing wage in Oregon is the minimum hourly pay — base rate plus fringe benefits — that contractors must pay workers on publicly funded construction projects over $50,000. The Bureau of Labor and Industries (BOLI) sets the rates by trade and region, and the rules reach into overtime, payroll reporting, bonding, and job site postings. Miss any of them and the penalties stack quickly.
The system is sometimes called Oregon’s “Little Davis-Bacon Act.” Its purpose is to stop contractors from winning government bids by cutting worker pay, pushing competition toward efficiency and quality instead.
When Prevailing Wage Applies
The requirements live in ORS 279C.800 through 279C.870. “Public works” covers construction, reconstruction, major renovation, demolition, hazardous waste removal, and painting done for or on behalf of a public agency.1Oregon State Legislature. Oregon Revised Statute Chapter 279C – Public Contracting “Public agency” means the State of Oregon plus any county, city, district, authority, or public corporation organized under state law.
The threshold is $50,000 in total project cost, counting all contracts for materials, supplies, and labor together.2Oregon State Legislature. Oregon Revised Statutes 279C-810 – Exemptions; Rules Splitting a project into smaller contracts doesn’t help: if the pieces together top $50,000, the whole project is covered. Solar installations on public property are the exception that goes the other way — no minimum threshold, so prevailing wage applies regardless of cost.3Oregon Bureau of Labor and Industries.

Two categories of projects are exempt even above $50,000. Private projects with limited public involvement escape the law only when all four of these conditions are met: the project is privately owned, funded with private money, occupied by a public agency in less than 25 percent of its finished square footage, and uses less than $750,000 in public funds.2Oregon State Legislature. Oregon Revised Statutes 279C-810 – Exemptions; Rules Privately owned residential construction that predominantly provides affordable housing is also exempt. “Predominantly” means 60 percent or more of the units serve occupants earning no more than 60 percent of area median income (or 80 percent for owner-occupied housing), and the buildings must be four stories or fewer.1Oregon State Legislature. Oregon Revised Statute Chapter 279C – Public Contracting
Where a project blends public and private funds and doesn’t fit one of those exemptions, the entire project is typically covered if the public portion is significant. That includes situations where a private developer builds something a government entity will later lease or occupy.
How Rates Are Set and Which Rate Book Applies
BOLI determines prevailing rates by surveying actual wages paid in each trade across different parts of the state. The commissioner must publish rates at least once a year, but in practice BOLI updates them quarterly, on January 5, April 5, July 5, and October 5.4State of Oregon. Prevailing Wage Rates Rates vary by occupation and by county or region. An electrician in Portland and an electrician in Bend will see different numbers.
For most projects, the rates that apply are the ones in effect when the public agency first advertises the project for bids. Those rates then lock in for the life of the project, even if BOLI publishes higher numbers later.5Oregon State Legislature. Prevailing Wage Rate Laws – A Handbook for Public Agencies, Contractors and Subcontractors in Oregon For projects where no public agency directly awards a construction contract — say, a private developer building on public land — the applicable rates are those in effect when the public agency first enters an agreement with the private entity.
Projects that take federal money may also fall under the federal Davis-Bacon Act. When both laws apply, workers must be paid whichever rate is higher for their trade and location.6Oregon State Legislature. Prevailing Wage Rate Presentation
Base Pay Plus Fringe Benefits
Every published rate has two parts: a base hourly rate and a fringe benefit rate. The total of the two is what the contractor owes per hour for each worker in a given trade.5Oregon State Legislature. Prevailing Wage Rate Laws – A Handbook for Public Agencies, Contractors and Subcontractors in Oregon
The fringe portion can be satisfied through employer contributions to qualifying benefit programs such as health insurance, pension plans, vacation plans, and apprenticeship training. Contributions have to be made regularly, at least quarterly, and cannot cover benefits already required by law like workers’ compensation.
Contractors have flexibility in how they divide the total between cash and benefits, as long as the combined value meets or exceeds the published rate. If a contractor provides no benefits at all, the entire fringe amount must be paid to the worker as additional cash wages on regular paydays.
Daily Overtime, Weekends, and Holidays
Overtime on Oregon public works runs on a daily clock, not just a weekly one. Workers earn overtime after eight hours in a single day, Monday through Friday, even if they haven’t hit 40 hours for the week.7Oregon Bureau of Labor and Industries. Prevailing Wage Rate Laws – 2024 Handbook That daily trigger catches out-of-state contractors who are used to overtime starting only at 40 weekly hours. A limited exception exists for an established four-ten schedule (four 10-hour days), where daily overtime may not apply until after the tenth hour.
All hours worked on Saturdays, Sundays, and the following six legal holidays must be paid at overtime rates no matter how many hours the worker has already logged that week:
- New Year’s Day
- Memorial Day
- Independence Day
- Labor Day
- Thanksgiving Day
- Christmas Day
When one of these holidays falls on a weekend, the preceding Friday or following Monday becomes the recognized holiday for overtime purposes. The overtime rate is 1.5 times the base hourly rate, plus the full fringe rate.
What Contractors Must Do on a Covered Job
File a Public Works Bond
Before starting work on any covered public works contract or subcontract, a contractor must file a $30,000 public works bond with the Construction Contractors Board.1Oregon State Legislature. Oregon Revised Statute Chapter 279C – Public Contracting The bond must be issued by a corporate surety authorized in Oregon and guarantees payment of any wage claims BOLI orders. It stays in effect continuously until depleted by paid claims, and if the surety pays out, the Board can require a new $30,000 bond before work continues. This is a prerequisite, not something to sort out after mobilizing on site.
Post Rates at the Job Site
Every contractor and subcontractor on a covered project must post the applicable prevailing wage rates in a visible location where employees can easily see them.8Oregon Secretary of State Administrative Rules. Oregon Administrative Code 839-025-0033 – Posting Requirements If the contractor contributes to a health or pension plan on workers’ behalf, an additional notice must sit alongside the rates describing the plan, explaining how to file claims, and stating where to get more information. Intentionally failing to post is grounds for debarment.
Submit Certified Payroll Weekly
Contractors and subcontractors must prepare certified payroll reports every week. Each report has to include, for every worker, the name, address, work classification, daily hours, pay rate, gross and net pay, deductions, and the amount contributed to any fringe benefit program.5Oregon State Legislature. Prevailing Wage Rate Laws – A Handbook for Public Agencies, Contractors and Subcontractors in Oregon BOLI provides a standard form, WH-38, with a signed certification that the wages paid meet or exceed the prevailing rate.
The weekly reports must reach the project’s public agency by the fifth business day of the following month.9Oregon Bureau of Labor and Industries. Certified Payroll Reporting on Public Works Projects Miss that deadline and the public agency is required to withhold 25 percent of amounts owed to the prime contractor until the reports arrive.5Oregon State Legislature. Prevailing Wage Rate Laws – A Handbook for Public Agencies, Contractors and Subcontractors in Oregon All payroll records must be kept for at least three years after the project wraps up, and BOLI can inspect them at any reasonable time.
What It Costs to Get It Wrong
Oregon stacks three layers of consequences on prevailing wage violations: back pay with liquidated damages, civil penalties, and debarment.
A contractor that underpays workers owes the full amount of unpaid wages, including fringe benefits, plus an equal amount as liquidated damages. That effectively doubles the bill.1Oregon State Legislature. Oregon Revised Statute Chapter 279C – Public Contracting If the underpayment resulted from willfully falsified payroll records, the liquidated damages multiplier for unpaid overtime jumps to twice the unpaid amount, tripling the total.
On top of that, BOLI can assess civil penalties of up to $5,000 per violation. Failing to pay the correct base rate and failing to pay the correct fringe amount count as separate violations, and for continuing violations each day is treated as a distinct offense. Weeks of underpayment to a crew can produce stacked penalties that dwarf the original wage shortfall.
The most damaging consequence for a repeat or intentional violator is debarment: a three-year ban from receiving any public works contract or subcontract in Oregon. BOLI can debar a contractor for intentionally underpaying workers, intentionally failing to post wage rates at the job site, or intentionally falsifying certified payroll statements. The ban also extends to any firm, corporation, partnership, or LLC in which the debarred contractor has a financial interest, so reorganizing under a new business name is not a way out.
