The Oregon modular wage lawsuit challenges the state’s reach into factory work for public projects. The August 19, 2026, complaint seeks relief; filing it does not itself suspend the requirements. Project scope depends on procurement timing, specified bespoke work and stated exceptions, including certain standard modular housing. Filed complaint, BOLI’s coverage FAQ.

For affordable-housing developers and manufacturers pricing contracts, the immediate task is to establish which activities a quote includes and why they are covered or excluded. Neither the factory’s location nor the label “modular” supplies the whole answer.

What MBI v. Stephenson challenges

The Modular Building Institute (MBI) sued Christina Stephenson in her official capacity as commissioner of Oregon’s Bureau of Labor and Industries (BOLI). Pacific Legal Foundation, which represents MBI, announced the filing on August 19, 2026. Plaintiff counsel’s announcement.

The complaint challenges HB 2688 and its implementing rules under the dormant Commerce Clause, Foreign Commerce Clause and Fourteenth Amendment’s Due Process Clause. MBI alleges unconstitutional burdens on manufacturing outside Oregon and inadequate notice of when customization becomes covered bespoke work. It seeks a declaration of unconstitutionality and a permanent injunction against enforcement of the challenged provisions against its members. These are allegations and requested remedies, not judicial findings. Complaint, claims and requested relief.

The geographic dispute has a direct pricing consequence: MBI says covered factory workers elsewhere must receive the wage applicable to the Oregon project’s locality. Its challenge concerns both compensation and the compliance burden of supplying those projects. Complaint, paragraphs 27–36.

Which date controls a procurement?

HB 2688 was enacted in 2025 as Oregon Laws chapter 612. The act’s effective date is distinct from the date its procurement changes became operative. Legislative record.

Section 2 makes the procurement cutoff precise: the amendments apply when the contracting agency solicits the procurement on or after July 1, 2026. If there is no solicitation, the relevant event is entering into the public contract on or after that date. HB 2688, sections 2–3.

A hypothetical June solicitation followed by an August award does not cross this cutoff merely because the award occurred after July 1. Other prevailing-wage obligations may still apply. To assess this question of implementation and regulatory scope, teams need the solicitation record as well as the signed contract.

Which off-site work falls within the expansion?

Start with the underlying project. HB 2688 connects the new category to specified public-works projects; it does not establish a wage requirement for every privately purchased factory-built home. Oregon also retains project exemptions, including qualifying privately owned residential construction that predominantly provides affordable housing. Ownership, funding and the statutory definitions require their own review. ORS 279C.800 and 279C.810.

For the new off-site category, the statute requires fabrication, assembly, preconstruction or construction that is bespoke, performed off-site, and undertaken specifically for a qualifying project according to its specifications. The work must also involve a listed system or component. These requirements operate together. HB 2688, section 1.

BOLI describes bespoke work as work following individualized specifications in the public-works contract or associated documents, including plans. It calls the off-site places where covered work occurs satellite locations. June 4 FAQ.

The listed categories encompass mechanical and plumbing systems; specified electrical systems; boilers; ornamental and structural ironwork; masonry and plaster; roofing, flashing and architectural panels other than glazing; and mechanical insulation. Electrical coverage incorporates the statutory requirements referenced in the law. BOLI summarizes these categories in its June 2026 prevailing-wage handbook.

A supplier’s proposal therefore needs to identify the fabrication activities and products being priced. Describing the delivery only as a modular building leaves the coverage question unresolved.

Exceptions for standard modular housing and manufactured dwellings

The final rule’s definition of bespoke work excludes work creating manufactured dwellings as defined in ORS 446.003. Separately, it excludes work creating volumetric modular housing—factory-built, three-dimensional dwelling modules—based exclusively on standard designs or dimensions without modification. These are distinct exclusions; describing a product as factory-built does not establish either one. OAR 839-025-0004(4).

The definition also excludes work performed before the public-works solicitation, qualifying unmodified standard mass-timber products, concrete/asphalt/aggregate work and derived products, paint-color work, and specified applied art. These limits concern the bespoke category; they do not determine every obligation for installation or other work at the project site. BOLI’s definition and exclusions.

To evaluate the modular-housing exception, compare the catalogue drawing and its revision history with the project’s requested changes. Those records can help identify which activities need a coverage decision.

Two hypothetical procurement scenarios

Assume an otherwise covered Oregon public-works housing procurement was solicited on July 10, 2026:

• Unmodified dwelling modules: The proposed factory work creates volumetric modular housing using exclusively standard designs and dimensions, without modification. The modular-housing exclusion is directly relevant; retain the documents supporting that description.
• Project-specific plumbing fabrication: The manufacturer must fabricate plumbing assemblies to individualized contract plans. That activity warrants review under the listed plumbing category, even if the supplier starts with a familiar building model.

These examples illustrate the statutory and regulatory tests, not determinations about actual contracts. A design change requested after an initial quote should prompt a fresh scope review. Statutory coverage test, modular-housing exclusion.

What to establish before fixing the price

BOLI’s FAQ says companies performing covered bespoke off-site work must follow the rules applicable to contractors working at the project site. Its employer guidance explains that prevailing compensation includes base and fringe amounts, and that covered contractors have certified-payroll responsibilities. Off-site FAQ, BOLI employer guidance.

For construction cost planning, ask the supplier to state its coverage assumption, the activities and hours priced under that assumption, and responsibility for resolving later design changes. Leaving those points open can conceal a disagreement about who bears additional labor or administration costs. Consult Oregon prevailing-wage counsel where the contract specifications leave coverage uncertain.

Had a court order changed obligations by August 21?

No order blocking enforcement was identified in the records reviewed for this article. The available public docket copy lists the complaint, a case-assignment and scheduling order, and summonses, all dated August 19. It also identifies August 19 as its last retrieval date, so it cannot conclusively establish the absence of an August 20–21 order. Public docket copy.

The filing alone supplies no basis to stop compliance. When tracking this housing litigation, look for an actual order specifying whether enforcement is restricted, for whose benefit and over which work.
