The 21st Century ROAD to Housing Act became law without President Donald Trump’s signature after the constitutional period for presidential action expired, completing an unusual path for a bipartisan measure intended to increase the supply of housing and reduce costs.

The legislation took effect automatically at midnight after Trump neither signed nor vetoed it. Under the US Constitution, a bill approved by both chambers of Congress becomes law if the president does not return it within 10 days, excluding Sundays, while Congress remains able to receive a veto. House Speaker Mike Johnson sent the measure to the president on June 29, beginning that process. [Source 14462]

Congress had approved the housing package by wide bipartisan margins. Trump had initially been expected to sign it during a ceremony on Capitol Hill, but the event was canceled. He subsequently said he would withhold his signature to protest the Senate’s failure to advance the SAVE America Act, a separate elections proposal that would establish additional rules for voting and voter registration. He did not veto the housing bill, allowing it to take effect independently of that dispute. [Source 14462]

The new law contains more than 45 provisions addressing housing construction, financing and access. Several are designed to remove regulatory obstacles to affordable housing development and accelerate environmental reviews. The law also establishes a pilot program to help local governments convert vacant commercial properties into affordable homes. [Source 14462]

Other provisions make additional federal funding available for factory-built housing and remove a requirement that homes be constructed on a steel chassis used during transportation. Communities that expand their housing supply may receive support through a newly created innovation fund, while separate measures seek to improve housing opportunities for veterans. [Source 14462]

The legislation also restricts institutional investors from buying certain single-family homes. Those limits apply to existing homes rather than newly constructed properties, an approach intended to reduce competition facing individual buyers while retaining incentives for financial firms to fund new development. Supporters argue that increasing supply and moderating investor demand can help address affordability pressures, although the law’s eventual effects will depend on implementation and local housing conditions.

The measure’s enactment followed months of congressional work and represented a comparatively rare bipartisan agreement on housing policy. Senator Elizabeth Warren of Massachusetts, a leading Senate advocate for the bill, welcomed its automatic enactment while criticizing Trump’s refusal to sign it. Johnson had also encouraged the president to approve the legislation, describing affordability and the cost of living as important issues, but said before the deadline that the measure would become law regardless of whether Trump signed it.

With the statutory process complete, attention will shift to federal agencies and participating communities responsible for putting the law’s development, conversion and investment provisions into practice.
