The affordable housing problem is a supply problem, and one of the largest sources of new supply has been shut out of the places that need it most. Bill Boor is President and CEO of Cavco Industries, which shipped 20,000 homes last year across 33 plants, enough to rank as the seventh-largest homebuilder in the country. Bill explains what the Road to Housing Act changed for factory-built housing, why removing the permanent chassis requirement opens up ground-set and two-story homes for urban infill, and how soon lenders might see them in the market. He also takes on the question lenders ask most, how to underwrite a product that no longer looks different from site-built, and makes the case that appraisals should reflect quality and condition rather than construction process.

Questions Answered
What did the Road to Housing Act change for manufactured housing?
Three things, according to Bill. It reaffirmed HUD as the industry’s regulator, which keeps other agencies from layering on rules that raise home costs. It directed federal agencies with construction and mortgage insurance programs to modernize them, since outdated loan limits had left some programs with zero use. And it removed the permanent chassis requirement from the federal definition of a manufactured home.
Why does removing the chassis requirement matter?
Without the chassis, factory-built homes can be set entirely at grade or built as two-story structures. This allows them to seamlessly blend into urban infill locations where raised foundations don’t make sense.
When will chassis-free homes hit the market?
The law is already in effect. While HUD rulemaking is still required, regulatory momentum and alternate construction letters mean these homes are already beginning to be delivered and placed.
How does this impact the affordable housing crisis?
It provides a scalable supply solution. Factory-built housing can hit price points that site-built construction simply cannot, offering true affordability without sacrificing energy efficiency or quality.

The Biggest Unlock in Housing: What the Road to Housing Act changed for factory-built housing
For 50 years, federal law mandated that manufactured homes sit on a permanent chassis. This year, the Road to Housing Act quietly removed that requirement, triggering what could be the most significant shift in housing supply in decades. On the latest episode of The Construction Lending Podcast, industry veteran Bill Boor explains why this single legislative change will reshape the housing market and what lenders need to know to stay ahead.
A Seat at the Table for Factory-Built Housing
The factory-built housing sector has long been viewed as a rural solution, despite the core of the affordability crisis being centered in urban and suburban markets. Outdated zoning rules and aesthetic stigmas historically kept manufactured housing out of these critical areas. However, a massive policy alignment is underway. Federal policymakers are now actively relying on factory-built housing as a primary solution to the supply shortage, and states are passing legislation to prevent local zoning laws from discriminating against homes based solely on their construction process.
The Chassis Comes Off
The most transformative element of the Road to Housing Act is the removal of the permanent chassis rule. Originally designed half a century ago so lenders could repossess and move homes, the rule forced modern manufactured homes to sit several steps above grade. Without this restriction, the industry can now produce ground-set homes that look and function exactly like site-built properties, as well as vertical, two-story homes. This allows factory-built homes to finally serve as viable options for high-density urban infill.
Redefining Affordability and Lending
Boor argues that true affordability isn’t about buyers settling for less space due to inflation; it is about whether a family can access homeownership at all. Site-built construction cannot scale efficiently enough to hit the lower price points the country desperately needs. Factory-built housing can bridge this gap without forcing buyers to trade down on quality, aesthetics, or energy efficiency.
For lenders and appraisers, this market evolution requires a mindset shift. When underwriting a factory-built duplex or a chassis-free home, the risk profile is converging entirely with traditional real estate. As these products hit the market, underwriting and appraisals must evolve to measure the condition, quality, and market fit of the home, rather than the location where its components were assembled.
