Oregon prevailing wage and certified payroll rules

Oregon's Prevailing Wage Rate (PWR) law covers public works over $50,000, with rates set by the Bureau of Labor and Industries (BOLI) and certified payroll on form WH-38 filed with the public agency every month. Starting July 1, 2026, some off-site fabrication is covered too.

Yes, Oregon has a state prevailing wage law, and it is one of the more demanding ones. BOLI says projects under $50,000, or projects that do not use public agency funds, may not be subject to the Prevailing Wage Rate law. Above $50,000, a project that meets the public works definition is covered even if the federal Davis-Bacon Act also applies. Contractors and subcontractors file certified payroll on BOLI's WH-38 for every week worked, and turn it in to the public agency once a month.

Which Oregon projects are covered

BOLI's starting point is simple: a public works project over $50,000 that uses public agency funds. The U.S. Department of Labor's state summary adds two details. Oregon has no general dollar threshold in the classic sense, but major renovations are only treated as public works if they exceed $50,000. And a project that uses $750,000 of public funds is a public work no matter who contracts for it, which pulls in some privately managed buildings that use public money.

Do not split a job to get under the line, and do not assume federal coverage replaces state coverage. When both apply, BOLI says the state law still applies, so plan to meet both sets of requirements on the same job. On non-residential projects covered by both, BOLI says to pay the higher of the state or federal rate for the work performed. BOLI also publishes coverage determinations if you are unsure whether a project qualifies.

The July 1, 2026 change: off-site bespoke work

House Bill 2688 from the 2025 session changes where prevailing wages are owed. BOLI's FAQ, published June 4, 2026, says the law becomes operative July 1, 2026 and applies to public works contracts entered into on or after that date. Before, prevailing wages were only paid at the site of work and nearby dedicated sites. Now they also reach satellite locations where certain "bespoke" systems and components are fabricated, assembled, or constructed. BOLI defines bespoke as work done to individualized specifications in the public works contract or related documents, including the plans.

  • Systems BOLI lists as possibly covered: HVAC, refrigeration, and other ducting or piping; plumbing; electrical systems or components; boilers; ornamental and structural iron; masonry and plaster; roofing, flashing, and architectural panels (glazing excluded); mechanical insulation.
  • Not bespoke, per BOLI: items built before the solicitation was issued, manufactured dwellings, standard factory modular dwellings, standard mass timber products, concrete, asphalt, and aggregate products, paint color, and applied art.
  • What it means for the shop: a company fabricating covered components off site must follow the same rules as contractors working at the project site.

Take a sheet metal contractor in Salem building custom ductwork in its own shop for a new county building. On a contract signed after July 1, 2026, those shop hours may now need prevailing wages and certified payroll, not just the install hours on site. If you fabricate for public jobs, flag every public contract by signing date and talk to the public agency or prime early.

Rates, overtime, and apprentices

BOLI publishes the rate books, usually in January and July, with amendments usually in April and October. Rates depend on the type of work, the county, and the date the public agency first advertised the project. Each rate has a base rate and a fringe benefits rate, and both must be paid. Post the applicable rates in a conspicuous place on the project.

Overtime is stricter than federal rules. BOLI says overtime is due after 8 hours a day Monday through Friday (or 10 on an established four-tens schedule), for all hours on Saturdays, Sundays, and six legal holidays, and for hours over 40 in a week.

Apprentices can be paid a percentage of the base rate only if they are registered with BOLI's Apprenticeship and Training Division or the federal apprenticeship office, work in their trade, and are employed by a registered training agent. They must stay within their program's apprentice ratio. If the ratio is broken, every apprentice working during that time gets the journey-level rate.

Certified payroll and penalties in Oregon

Contractors and subcontractors fill out WH-38 certified payroll for each week a worker is on a covered project and submit the reports to the public agency once a month, by the fifth business day of the following month. BOLI states plainly that the federal WH-347 does not satisfy its filing requirement. Keep records at least three years after the work is done.

  • Withholding: if the prime does not file monthly, the public agency withholds 25 percent of amounts earned and must pay it within 14 days after the reports arrive. Primes apply the same 25 percent withholding to first-tier subs who do not file.
  • False or incomplete information: can bring civil penalties and placement on BOLI's list of ineligible contractors.
  • Wage claims: workers can file prevailing wage claims for up to six years from the violation; the overtime claim period is two years.

How Oregon differs from Davis-Bacon

Davis-Bacon starts at $2,000, wants payroll weekly, and accepts WH-347. Oregon starts around $50,000, wants WH-38 filed monthly, adds daily overtime and weekend premiums, requires a $30,000 Public Works Bond on most jobs, and from July 2026 reaches into fabrication shops. On jointly funded work, you run both systems at once. Before bidding, also review the Oregon contractor license rules, Oregon mechanics lien rights, and Oregon prompt payment timelines.

Smart Business Automator tracks hours by classification, separates shop and field time, and prepares certified payroll from the same records, which matters more now that shop hours can count. See certified payroll automation.

Frequently asked questions

What is the prevailing wage threshold in Oregon?

BOLI says projects under $50,000 may not be subject to the PWR law. The U.S. Department of Labor adds that a project using $750,000 of public funds is a public work regardless of the contracting entity.

How often do I submit certified payroll in Oregon?

You complete a WH-38 for each week worked and submit the reports to the public agency monthly, by the fifth business day of the following month.

Can I use the federal WH-347 in Oregon?

BOLI's prevailing wage page says the WH-347 does not satisfy BOLI's filing requirement. Use the WH-38 or a report with all of its information, including the certified statement.

What happens if a contractor files certified payroll late in Oregon?

The public agency withholds 25 percent of amounts earned by the prime until reports are filed, then pays within 14 days. Primes withhold 25 percent from first-tier subs who do not file. False reports can bring civil penalties and ineligibility.

Does Oregon prevailing wage apply to off-site fabrication?

For public works contracts entered into on or after July 1, 2026, HB 2688 extends prevailing wages to bespoke systems and components built at off-site locations, such as custom ductwork, piping, and structural iron. Check with the public agency if unsure.
