Rows of mid-construction and fully assembled homes lined the National Mall in Washington this week, each one built to demonstrate a new construction technology meant to chip away at a housing affordability crisis. The sixth annual Innovative Housing Showcase ran Tuesday through Thursday, drawing federal officials, builders, and manufacturers to a stretch of the Mall that HUD Secretary Scott Turner said was there to highlight what he called the brilliance of the American people.
According to KPTV, the showcase featured the next generation of home building and development, with exhibitors providing building solutions and each home on display incorporating a new element or technology. Turner has said bureaucratic red tape and the regulatory environment are the main barriers standing between builders and affordable, workforce-attainable homes, per the same report. The event, organized by the U.S. Department of Housing and Urban Development, was photographed on the National Mall on September 23.
Among the exhibitors was Larry Singleton, founder of Singleton Designs, a firm based in Talking Rock, Georgia, who showed off a fast, affordable housing construction method designed to be picked up and delivered rather than built entirely on-site. Singleton noted that typical modular homes are shipped 200 to 300 miles from their construction facilities, and argued that shipping units so far away takes work away from local communities, the outlet reported. He said he hopes his housing concept gains traction going forward.
A Law That Cleared the Path for Stacked Modular Homes
The showcase's factory-built focus arrives just months after Congress reshaped the rules governing manufactured housing. The 21st Century ROAD to Housing Act, signed into law in July 2026, eliminated the 50-year-old federal requirement that manufactured homes be built on a permanent steel chassis, according to the Bipartisan Policy Center. By removing that mandate, federal lawmakers lowered production barriers and opened the door to stacked, multistory, and urban infill modular construction, the policy group's analysis notes.
The timing lines up with another milestone: the federal Manufactured Home Construction and Safety Standards, known as the HUD Code, marked its 50th anniversary in 2026, half a century after its original 1976 implementation, per the Manufactured Housing Institute. The HUD Code remains the sole preemptive federal building code in the country, which helps explain why manufactured housing occupied such a prominent place at this year's Mall showcase.
Builders Grapple With a Buyer Pool That Keeps Aging Up
National Association of Home Builders Chairman Bill Owens joined Turner on September 23 for the showcase's official ribbon cutting, an appearance that underscored NAHB's role as an original organizing partner since the event debuted in 2019. Owens spoke on a panel at the showcase. All-cash purchases made up 27% of August sales, according to the National Association of Home Builders.
Owens also detailed how builders are responding to the affordability squeeze: 66% reported offering buyer sales incentives, and 38% had cut home prices by an average of 6%, the association said. Those incentives reportedly include mortgage rate buydowns and fee concessions, moves builders are using to try to keep inventory moving as buyers stay priced out.
A Labor Shortage Pushes the Industry Toward the Factory Floor
Behind the push for factory-built solutions sits a blunt structural problem: residential construction faces an estimated 300,000-worker labor shortage in 2026, according to Realtor.com. That gap is a structural problem facing residential construction. The industry is also increasingly relying on off-site prefabrication and modular construction, which sidesteps the need for traditional on-site trade crews.
Manufactured housing already accounts for roughly 10% of all new homes built in the United States, housing more than 22 million Americans at costs 27% to 65% below site-built equivalents, per the Terner Center at UC Berkeley. That footprint makes manufactured units one of the clearest existing vehicles for entry-level homeownership, even as the median buyer keeps getting older.
Zoning and State Politics Still Shape the Rollout
HUD's Innovative Housing Showcase is an annual gathering on the National Mall for policymakers, manufacturers, and the public. Showcase organizers say they are aiming to find solutions that combine construction innovation with policy change, since HUD's own work centers on shaping housing policy nationally.
But turning Mall-floor prototypes into widely available housing still depends heavily on what happens far from Washington. In September, Texas cities were forced to accept manufactured homes under Senate Bill 785, which requires every municipality with zoning rules to permit new HUD-code manufactured homes in residential areas, dismantling local restrictions that had historically limited where such homes could go. While the technology on display on the Mall promises clear construction cost savings, its broader adoption still hinges on state-level code updates and local municipal zoning decisions playing out city by city.
