Do you believe factory-built housing will effectively alleviate the affordable housing crisis in the U.S.?
The 21st Century ROAD to Housing Act, which became law in summer 2026, eliminated the mandate for permanent steel frames on manufactured homes. This regulatory change aims to increase national housing supply by streamlining the construction of factory-built units.
Why it matters
The legislation removes a significant barrier to design flexibility and production efficiency for modular builders, potentially lowering total project costs. These changes are intended to help address the national shortage of housing options by accelerating the delivery of off-site builds.
Factory-built construction offers a 30% to 50% speed advantage and 5% to 10% lower pricing versus traditional methods. The industry currently includes players like RISE Modular, which operates a 150,000-square-foot factory and employs approximately 200 workers.
The players
RISE Modular
A construction company that operates a 150,000-square-foot factory in Owatonna, Minnesota, and employs approximately 200 workers.
Department of Housing and Urban Development
A federal agency responsible for national housing policy and the investigation into modular housing building codes.
The details
Modular builders construct three-dimensional units with finished interiors in a factory environment before transporting them to the final site for assembly. Under the new law, builders no longer have to incorporate permanent steel frames, allowing for greater variety in foundation and structural design. These units must still meet all applicable local building codes despite being constructed off-site.

Market Landscape
The enactment of the 21st Century ROAD to Housing Act follows persistent industry efforts to standardize off-site construction processes. It sits alongside broader government initiatives to address housing shortages by removing legacy regulatory requirements.
Operators in the housing sector should evaluate how the removal of permanent steel frame requirements impacts their structural design costs and procurement needs. Keep watch for upcoming federal guidance from the Department of Housing and Urban Development regarding national modular building codes.
The takeaway
The easing of federal frame mandates offers an opportunity to optimize production costs and broaden residential design capabilities. Owners should monitor the Department of Housing and Urban Development's forthcoming study on a federal code to prepare for potential future alignment of local building requirements.
