Modular housing fails to scale. Will policy reforms alter that?

The 21st Century ROAD to Housing Act, recently enacted by Congress, contains targeted provisions aimed at removing regulatory and financing obstacles that have kept off‑site, modular construction from scaling in the United States. Sections 302 and 303 of the law focus on standardizing building codes, revising draw schedules, and updating FHA loan limits to make factory‑built homes more viable. Currently, modular units account for only three percent of the roughly 100,000 new homes built each year, according to the National Association of Home Builders, a figure policymakers hope to boost as a remedy for the nation’s deepening affordable‑housing shortage. Former HUD commissioner and now senior managing director at Walker & Dunlop, Frank Cassidy, championed the legislation, arguing that “we have to build our way out of” the crisis and that modular construction should be treated as mainstream housing infrastructure.

The act’s most consequential element is its push for a national, performance‑based building code that would supersede the fragmented state and local standards that currently hinder modular projects. Section 302 directs HUD to identify and eliminate barriers such as rigid construction draw schedules, restrictive FHA loan caps, and inconsistent zoning rules, while also commissioning a study to create a unified code modeled on the manufactured‑housing HUD standard. Cassidy contends that such a code would allow manufacturers to innovate without being constrained by prescriptive regulations, provided that health and safety outcomes are met. In parallel, Section 303 seeks to streamline financing by expanding FHA loan limits for off‑site builders and introducing more flexible draw structures, addressing the financing gap highlighted in a 2026 Modular Home Builders Association report that identified a shortage of lenders familiar with the factory‑first cash flow model.

Implementation of these reforms will require coordination among federal agencies, state and local governments, and private lenders. If HUD succeeds in establishing a national code and the FHA adjusts its financing rules, developers could access the capital needed to fund the upfront factory costs that have traditionally deterred lenders. This could accelerate the delivery of higher‑density, better‑designed homes, potentially reshaping the affordable‑housing market. However, Cassidy warns that without complementary zoning reforms at the state and municipal level, the federal changes alone may fall short. The next steps involve HUD’s mandated study, the rollout of revised draw schedules, and outreach to lenders such as Fannie Mae and Freddie Mac to ensure that the new financing frameworks are operational, setting the stage for modular housing to move from a niche segment to a mainstream solution.
