Modular Building Institute Sues Oregon Over Wage Rule

The Modular Building Institute (MBI) has filed a lawsuit against the state of Oregon, challenging House Bill 2688 and a subsequent administrative rule that mandates the application of Oregon's prevailing wage laws to modular construction projects. The lawsuit, filed in the U.S. District Court for the District of Oregon, argues that the rule unlawfully extends state wage requirements to out-of-state manufacturers producing bespoke modules. The MBI contends that this regulation unfairly burdens its members and disrupts the modular construction industry by imposing wage and benefit standards that are not applicable to the manufacturing process itself, which typically occurs off-site in controlled factory environments. The rule in question, set to take effect on July 1, 2026, aims to ensure that workers involved in the creation of modular components receive wages comparable to those on traditional construction sites within Oregon.

Oregon's HB 2688, enacted in 2023, sought to address perceived wage disparities in the construction sector. The bill's provisions, as interpreted by the Oregon Bureau of Labor and Industries (BOLI), extend to the fabrication of modular units intended for use in Oregon. This interpretation means that manufacturers, regardless of their location, must adhere to Oregon's prevailing wage rates and benefit requirements for any modules destined for installation within the state. The MBI asserts that this is a misapplication of prevailing wage laws, which are traditionally applied to on-site construction labor. The institute argues that the manufacturing of modular components is a distinct process from on-site assembly and should not be subject to the same wage regulations.

The lawsuit highlights a growing tension between traditional construction methods and the increasing adoption of modular and off-site construction techniques. Proponents of modular construction emphasize its potential to increase efficiency, reduce costs, and address labor shortages. However, the application of state-specific labor regulations to a manufacturing process that can occur anywhere raises significant legal and economic questions. The MBI's legal challenge seeks to clarify the scope of prevailing wage laws in the context of modern construction practices and to prevent what it describes as an overreach by state regulators. The outcome of this case could have significant implications for the modular construction industry nationwide, potentially setting a precedent for how such regulations are applied in other states.

The MBI represents a diverse group of companies involved in the design, manufacturing, and installation of modular buildings. The organization advocates for policies that support the growth and innovation of the modular construction sector. By filing this lawsuit, the MBI aims to protect its members from what it views as an unfair and potentially prohibitive regulatory burden. The suit specifically targets the rule implemented by BOLI, which is the state agency responsible for enforcing labor laws in Oregon. The legal filing details the MBI's arguments that the rule violates federal law, including the Commerce Clause of the U.S. Constitution, by discriminating against out-of-state manufacturers. The institute is seeking an injunction to prevent the enforcement of the rule and a declaration that it is unlawful.
