The legal boundaries of state labor authority are facing a significant challenge in federal court as the Modular Building Institute (MBI) moves to block an Oregon law that seeks to regulate wages paid to workers in factories located far beyond the state’s borders. The lawsuit, filed on Wednesday against Oregon’s Labor Commissioner, marks a pivotal moment in the intersection of labor rights, interstate commerce, and the burgeoning modular housing industry. At the heart of the dispute is House Bill 2688, a piece of legislation that expands the definition of public works to include off-site fabrication, requiring that any "bespoke" components used in Oregon public projects be produced at Oregon-equivalent prevailing wage rates, regardless of where the factory is situated.
The Modular Building Institute, a global trade association representing 708 companies in the modular construction sector, argues that Oregon has overstepped its constitutional authority. Represented by the Pacific Legal Foundation, the MBI contends that the state is attempting to project its regulatory power across state lines, a move they claim violates the Commerce Clause and infringes upon federal jurisdiction over foreign trade. The outcome of this case is expected to set a national precedent; a victory for Oregon could embolden other states to adopt similar "reach-across" wage mandates, while a victory for the MBI would reinforce the traditional boundaries of state labor law.
The Legislative Foundation and the "Bespoke" Mandate
Oregon’s House Bill 2688 was conceived as part of a broader legislative push to address the state’s chronic housing shortage and to ensure that public funds support high-wage labor. For decades, prevailing wage laws in Oregon—and most other states—applied strictly to the physical construction site. Workers hammering nails or pouring concrete on-site at a public library or a government-funded housing complex were entitled to the local prevailing wage. However, the components of those buildings, if manufactured elsewhere, were generally treated as commodities exempt from such wage requirements.
Under the new rules established by the Oregon Bureau of Labor and Industries (BOLI), which took effect on July 1, 2026, this distinction has been erased for modular components. The law now specifies that if a component is "bespoke"—meaning custom-made for a specific project rather than a mass-produced, off-the-shelf item—the manufacturer must pay its employees the Oregon prevailing wage for the duration of that production. This applies even if the factory is located in a state with a significantly lower cost of living or even in a foreign country.
Legal counsel for the Pacific Legal Foundation, Wilson Freeman, highlighted the constitutional concerns inherent in this approach. "Oregon cannot reach across state lines and dictate how businesses operate in other states simply because a finished product is later used on an Oregon public project," Freeman stated. The lawsuit argues that this creates an unconstitutional burden on interstate commerce by forcing out-of-state businesses to alter their internal pay structures to satisfy a single client in the Pacific Northwest.
A Chronology of Oregon’s Evolving Housing and Labor Policy
To understand the current legal friction, it is necessary to examine the timeline of Oregon’s aggressive housing reforms over the past several years. The state has been at the forefront of "middle housing" initiatives, attempting to dismantle traditional single-family zoning to make way for more density.
- 2019: Oregon passes House Bill 2001, effectively ending single-family-only zoning in most cities. This law required municipalities to allow duplexes, triplexes, and fourplexes in areas previously reserved for standalone houses. It also mandated the inclusion of manufactured and modular homes in these zones.
- 2023: House Bill 2688 is introduced and signed into law. While intended to bolster labor standards, it creates immediate concern within the modular industry regarding the feasibility of interstate contracts.
- 2025: The Oregon Legislature doubles down on housing production with HB 2138 and HB 2258. These bills aimed to streamline the permitting process and provide financial incentives for modular housing developers to meet the state’s goal of building 36,000 new units per year.
- December 2025: New York follows Oregon’s lead, enacting a similar expansion of prevailing wage rules for off-site custom fabrication. However, unlike Oregon, New York faced immediate pushback and entered negotiations with industry stakeholders.
- February 2026: New York Governor Kathy Hochul signs a "clean-up" bill that narrows the scope of the New York law, providing exemptions for certain types of modular production and clarifying the definition of custom work to avoid a total industry freeze.
- July 1, 2026: Oregon’s expanded prevailing wage rule officially takes effect without the "clean-up" modifications seen in New York.
- Present: The MBI files its federal lawsuit, seeking a permanent injunction against the enforcement of the off-site provisions.
Economic Data and the Cost of Compliance
The economic implications of HB 2688 are substantial. The modular housing industry relies on the "factory model" to keep costs predictable and lower than traditional stick-built construction. By centralizing labor in a controlled environment, modular companies can often produce housing units 20% to 50% faster than on-site builders.
However, the wage disparities between states can be vast. For example, the prevailing wage for a carpenter in Portland, Oregon, might be upwards of $55 per hour (including benefits). In contrast, a modular factory worker in a state like Idaho or South Carolina might earn a market rate of $22 to $28 per hour. If an Oregon public housing project utilizes modules built in an Idaho factory, HB 2688 requires that Idaho factory to pay the $55 Oregon rate for the time spent on those specific units.
Industry analysts point out several administrative and financial hurdles:
- Dual-Wage Systems: Factories would be forced to run "split payrolls," paying workers one rate for an Oregon project and a different rate for a local project on the same day. This creates significant accounting overhead and potential labor unrest among factory staff.
- Audit Risks: Out-of-state firms would be subject to audits by Oregon’s BOLI. Failure to comply could result in debarment from all future Oregon public contracts, civil penalties, and back-pay liabilities.
- Increased Project Costs: Estimates suggest that applying Oregon’s prevailing wages to out-of-state production could increase the cost of modular units by 15% to 30%, potentially neutralizing the cost-savings that make modular housing an attractive solution for the affordable housing crisis.
Legal Arguments: The Three Pillars of the MBI Challenge
The MBI’s complaint is built upon three distinct legal theories, each targeting the constitutionality and clarity of the Oregon law.
1. The Dormant Commerce Clause
The primary argument rests on the "dormant" Commerce Clause of the U.S. Constitution. This legal doctrine prevents states from passing legislation that discriminates against or excessively burdens interstate commerce. The MBI argues that by requiring out-of-state factories to adhere to Oregon’s local wage scales, the state is essentially penalizing companies for being located outside of Oregon. This, they claim, creates a protectionist barrier that favors Oregon-based manufacturers over those in other states.
2. Foreign Commerce and Federal Preemption
The lawsuit also addresses the international implications of the law. Because modular components are sometimes sourced from Canadian or overseas manufacturers, Oregon is effectively attempting to regulate foreign labor. The MBI asserts that the power to regulate commerce with foreign nations is reserved exclusively for the federal government. By dictating wages in foreign jurisdictions, Oregon is seen as intruding upon the U.S. State Department’s and Congress’s domain.
3. The "Bespoke" Vagueness Challenge
The third pillar of the suit concerns the term "bespoke." The MBI argues that the term is "hopelessly vague" and fails to provide manufacturers with a clear standard for compliance. In the modular industry, almost every project involves some level of customization—changing a floor plan slightly, choosing different finishes, or adjusting window placement. The MBI asks: At what point does a standard design become "bespoke"? Without a clear definition, the MBI argues that companies are left to guess, facing severe legal and financial consequences if they guess wrong.
Implications for the Housing Crisis and Future Policy
The irony of the current legal battle is not lost on housing advocates in the Pacific Northwest. Oregon has been a national leader in zoning reform, specifically encouraging the use of manufactured and modular homes to bridge the supply gap. By making it easier to place these homes on residential lots, the state signaled a commitment to innovative construction methods.
However, the new labor rules may create a "chilling effect." If out-of-state manufacturers decide that the administrative burden of Oregon projects is too high, they may simply stop bidding on Oregon public works. This would reduce competition and likely drive up the price of affordable housing projects funded by the state, at a time when Oregon is desperate to maximize every dollar of its housing budget.
Furthermore, the federal government is currently exploring its own role in the modular industry through the "ROAD to Housing Act." This federal legislation includes provisions for a Modular Housing Production Act, which directs the Department of Housing and Urban Development (HUD) to study and remove barriers to modular financing. While the federal act does not directly interfere with state wage laws, the MBI’s support for the ROAD Act highlights a preference for federal standardization over a patchwork of conflicting state-level mandates.
Conclusion and Judicial Outlook
As the case moves through the federal court system, the construction and labor sectors will be watching closely. A ruling in favor of the Modular Building Institute would likely limit the ability of states to enforce local labor standards on products manufactured elsewhere, preserving the current "commodity" status of off-site components. Conversely, a ruling in favor of Oregon could revolutionize public procurement, allowing states to use their purchasing power to export their labor standards across the country.
For now, the MBI is seeking a permanent injunction to prevent Oregon from enforcing the off-site provisions of HB 2688. Until the court reaches a decision, the modular industry remains in a state of uncertainty, balancing the need for innovative housing solutions against the complex and evolving landscape of state labor regulations. The final verdict will determine whether the "Oregon model" becomes a blueprint for the nation or a cautionary tale of regulatory overreach.
