Follow the Paper Trail: How Oregon’s SB 426 and HB 4089 Are Rewriting the Rules for Every Contractor on Your Jobsite

April 23, 2026

If you’re a general contractor or subcontractor working in Oregon, the state legislature has sent you a clear message over the past two years: the days of looking the other way on wage violations and unlicensed labor are over.

In back-to-back legislative sessions, Oregon has passed two significant laws targeting construction labor practices — Senate Bill 426, which took effect January 1, 2026, and House Bill 4089, signed into law on March 31, 2026 and set to take effect January 1, 2027. Taken together, they represent the most aggressive legislative push to reform construction labor accountability in Oregon in recent memory. Here’s what every Oregon contractor needs to understand.

SB 426: You Are Now Responsible for Your Subcontractors’ Wage Violations

Senate Bill 426 fundamentally changed the liability landscape for general contractors and property owners in Oregon. Before the law took effect, if a subcontractor failed to pay its workers, those workers’ legal remedies were largely limited to pursuing the subcontractor directly — a process that often proved fruitless when the sub had no assets or had simply disappeared.

SB 426 changed that equation entirely. Under the new law, direct contractors — and in some cases property owners — are jointly and severally liable for any unpaid wages, including fringe benefit contributions, owed to unrepresented employees of subcontractors at any tier of the contracting chain. That means if your sub’s sub doesn’t pay its workers, you could be on the hook — even if you already paid your subcontractor in full.

Critically, this law applies specifically to unrepresented employees — workers who are not covered by a collective bargaining agreement that includes a binding grievance procedure and a mechanism for recovering unpaid wages. Union workers covered by qualifying CBAs are generally excluded. But on open-shop commercial and large residential projects, nearly every worker on your site is likely an unrepresented employee under this definition.

Who Is Excluded Under SB 426?

The law does carve out some important exceptions. SB 426 does not apply to:

Projects involving five or fewer residential or commercial units on a single tract of land. Small residential builders and developers — think duplexes, fourplexes, and small infill projects — are largely outside the law’s reach.
An owner’s primary residence. Projects involving construction, reconstruction, alteration, maintenance, or demolition of the property owner’s principal residence are exempt.
Public agencies. Public agencies are expressly excluded from the definition of “owner” for purposes of liability under this law.
Financial institutions that acquire ownership through foreclosure, as long as they don’t take over management of the project.

If your work is primarily small residential or custom home construction, this law may have limited direct impact on you. But if you’re doing mid-size to large commercial work, multifamily projects of six units or more, or any mixed-use development, SB 426 applies squarely to your projects — and the exposure is significant.

Before filing a lawsuit, claimants must send written notice to the owner and direct contractor describing the alleged violation and giving 21 days to correct it. If the violation is remedied within that window, no civil action can proceed. That 21-day cure period is an important reason to have your compliance systems in place before a notice ever arrives — not after.

HB 4089: Hiring Unlicensed Labor Just Became a Criminal Matter

If SB 426 hit contractors in the wallet, HB 4089 hits them somewhere more serious — their criminal record.

Effective January 1, 2027, HB 4089 makes it a Class A misdemeanor — punishable by up to 364 days in jail and a $6,250 fine — for any direct contractor or subcontractor who knowingly enters into a contract with an unlicensed construction labor contractor. A second offense escalates to a Class C felony, carrying up to five years in prison and a $125,000 fine.

The law also dramatically stiffens penalties for CCB license number misuse. Intentionally using another contractor’s license number, or using one with the intent to deceive, is now a Class C felony as well — upgraded from a misdemeanor under prior law.

Beyond the licensing provisions, HB 4089 expands Oregon’s theft of services statute to cover partial payments, meaning that even a contractor who pays some of what they owe — but not all of it — can face criminal exposure. And critically, a criminal prosecution under the new law does not preclude a separate civil lawsuit or administrative proceeding. Workers and the state can pursue criminal charges and civil remedies simultaneously.

With eight months until HB 4089 takes effect, the time to get your house in order is now.

The Bigger Picture: A Clear Legislative Pattern

Read individually, SB 426 and HB 4089 are each significant. Read together, they tell a story about where Oregon is headed.

The legislature is clearly targeting the underground economy in construction — the network of unlicensed labor brokers, cash-pay operations, and multi-tier subcontractor chains that undercut legitimate contractors who carry proper insurance, pay prevailing wages, and maintain their CCB licenses. For years, compliant contractors have had to compete for bids against operators who win jobs precisely because they aren’t playing by the rules. These laws are designed to reduce that competitive disadvantage by raising the cost — financially and criminally — of cutting corners.

For Oregon contractors who are already doing things right, these laws are welcome news. For those who have been less careful about vetting their subcontractors and labor contractors, the window to get compliant is closing fast.

What Oregon Contractors Should Do Now

Attorneys and risk management experts across Oregon are recommending the same set of core actions. Here’s where to start:

1. Verify licensing, insurance, and workers’ compensation before anyone sets foot on your site. Before allowing any subcontractor — at any tier — to begin work, require and verify three things: a current, valid CCB license; a certificate of insurance naming you as an additional insured; and a certificate of workers’ compensation insurance. This is not a one-time task at contract signing — make sure this is current for each subcontractor of any tier on your jobsite for the entire time the subcontractor is on your jobsite. An unlicensed or uninsured sub showing up on your site is a civil liability and, under HB 4089, may become a potential criminal exposure.

2. Use Oregon’s free license monitoring tools. Oregon’s CCB e-Watch system allows contractors to monitor subcontractor license status in real time and receive email alerts if a license lapses or is suspended. Washington Labor & Industries offers a similar tracking system. Every GC should be using both — they are free and take minutes to set up.

3. Update your subcontracts and speak with your attorney. Your subcontract agreements should require proof of current licensing, certificates of insurance, and workers’ compensation coverage as a condition of contract execution and site access while subs are onsite. They should also require regular certified payroll submissions, disclosure of prior wage violations, and give you the right to withhold payment for non-compliance. Note that SB 426 explicitly prohibits contract language that attempts to waive or indemnify an owner or GC from wage liability — so indemnification clauses alone won’t protect you.

4. Implement payroll auditing throughout the chain. Under SB 426, subcontractors at every tier are required to provide certified payroll records, worker information, and a five-year wage violation history upon request. Build routine payroll audits into your project management process — not just at project start, but throughout construction. If a sub refuses to provide records or raises red flags, that is your signal to act before the 21-day cure clock ever starts ticking.

5. Train your team. The “I didn’t know” defense becomes much harder under HB 4089 when the operative word in the statute is “knowingly.” Your project managers, superintendents, and anyone involved in prequalifying, hiring or approving subcontractors should understand what these laws require and how to spot a potentially unlicensed labor contractor. Make this part of your onboarding and annual safety and compliance training.

6. Document everything. License verification records, certificates of insurance, certified payroll logs, and subcontractor compliance certifications need to be organized and retained. In any civil or criminal proceeding, your documentation trail will be your first — and often most important — line of defense.

Oregon isn’t done. The legislative appetite for construction labor enforcement appears to be growing, not shrinking. Contractors who treat compliance as a core part of their business operations — not a checkbox — will be the ones still standing when the next session convenes.
