US Housing Policy and Zoning Reform: Federal 21st Century ROAD to Housing Act Becomes Law Without President Trump's Signature
The most significant federal housing package in decades is officially law. At midnight on Saturday, July 11, 2026, the bipartisan 21st Century ROAD to Housing Act automatically became law without the signature of President Donald Trump.
The legislation had been delivered to the White House on June 29, 2026, by House Speaker Mike Johnson, starting a 10-day constitutional countdown. President Trump, who had previously dismissed the bill as "a big yawn" and canceled a scheduled White House signing ceremony, refused to sign the bill in protest of the Senate's failure to pass the voter ID-focused SAVE America Act. However, by taking no action—neither signing nor vetoing the bill before the July 10, 11:59 p.m. ET deadline—the President allowed the legislation to pass into law automatically.
Core Provisions of the New Housing Law
The bipartisan package contains over 40 distinct provisions aimed at stimulating supply, lowering construction costs, and restricting institutional buyers:
- Institutional Buyer Cap: In a provision that merged Democratic-backed proposals with Trump's own populist rhetoric, the law blocks corporate landlords who already own at least 350 single-family homes from acquiring additional properties. The policy aims to reduce institutional competition for individual buyers making cash offers, though organizations like Freddie Mac and the Urban Institute have historically argued that institutional buyers represent only a small fraction of the overall housing shortage.
- Pre-Approved "Pattern Books": The law establishes a federal grant program to help local communities develop "pattern books"—standardized, pre-approved residential designs. These pre-vetted blueprints can bypass lengthy local zoning and permitting processes, speeding up construction times.
- Manufactured Housing Deregulation: The law removes the federal requirement that manufactured homes must have a permanent steel chassis. Housing experts estimate this change will save between $5,000 and $10,000 in construction costs per home, and will allow builders to easily construct more complex modular designs, such as multi-story manufactured homes.
Market Outlook and Structural Limits
While the passage of the bill is a landmark bipartisan achievement, housing policy experts caution that federal legislation cannot unilaterally override local zoning codes, which remain the primary bottleneck for new residential supply.1 High labor and material costs also continue to weigh on developer sentiment. Nonetheless, the bill represents a structural shift in how federal policy supports affordable housing entry points.
