Trump Refuses to Sign Bipartisan Housing Bill, Which Becomes Law Without His Signature

Congress passed a rare bipartisan housing bill aimed at curbing the largest institutional buyers of single-family homes and expanding housing supply, only for President Trump to use the measure as leverage in an unrelated fight over election policy.

After the 21st Century ROAD to Housing Act cleared Congress in June 2026, Trump canceled a planned signing ceremony, refused to sign the bill, and dismissed it as "of minor importance." He also called it "a big yawn."

But the pressure campaign did not stop the legislation from becoming law. The 21st Century ROAD to Housing Act took effect on July 11, 2026, without Trump's signature after he neither signed nor vetoed it within the 10-day constitutional window while Congress remained in session. Under Article I, Section 7 of the Constitution, a bill becomes law automatically if the president neither signs nor vetoes it within 10 days, excluding Sundays, while Congress remains in session.

The result was the enactment of the first major affordable-housing legislation in more than three decades, including the first broad federal restriction on institutional ownership of single-family homes. The Senate had passed the measure 89-10 on March 12, 2026, signaling rare bipartisan consensus on housing costs.

Trump did not publicly oppose the substance of the housing bill. Instead, he posted on Truth Social that he would not sign it "in PROTEST" over the Senate's inability to pass the SAVE America Act, his preferred election security measure. The SAVE America Act would require proof of citizenship to register and government identification at the polls. It has faced strong Democratic opposition and criticism that it would disenfranchise eligible voters. Hours after canceling the housing-bill ceremony, Trump clashed with Senate Republicans in a tense closed-door meeting, reiterating that he would not sign the 21st Century ROAD to Housing Act while demanding action on the SAVE America Act.

The scale of the housing problem Congress sought to address is substantial. Some 20.7 million homeowner households are cost-burdened, while roughly half of renter households are cost-burdened. Harvard Joint Center for Housing Studies' 2026 State of the Nation's Housing report documented persistent affordability problems, finding that nearly half of renter households were cost-burdened in 2024 and that federal assistance remains far from meeting demand.

The law's most prominent restriction prohibits large institutional investors that already own at least 350 single-family homes from purchasing additional single-family homes. The ban includes 11 statutory exceptions, including for certain build-to-rent projects. It takes effect on Jan. 7, 2027, exactly 180 days after the Act's enactment, and is scheduled to sunset 15 years later, on Jan. 7, 2042. The restriction applies only to purchases made after the effective date and leaves pre-existing portfolios intact. Large institutional investors must report their holdings to HUD no later than 180 days after enactment and annually thereafter.

Even so, major single-family rental landlords are already putting more properties on the market and shifting capital toward permitted strategies, including build-to-rent and new-construction deals. Invitation Homes, Pretium, and Blackstone's Tricon Residential are planning to use carve-outs that still allow acquisitions in cases involving major renovation, tenant purchase options, and build-to-rent developments.

The institutional-investor limits are part of a broader package containing 47 provisions intended to expand housing supply. Those measures include streamlining environmental reviews, promoting manufactured and modular housing, expanding small-dollar mortgages, and directing HUD to provide guidance on zoning reforms. The law makes new affordable-housing construction eligible under Community Development Block Grants and expands access to manufactured homes by removing certain federal barriers.

It also includes disaster-recovery housing assistance, increased funding for homelessness programs, and protections and subsidies for rural renters and low-income households. As part of its tax-credit provisions, the bill increases the public welfare investment cap from 15 percent to 20 percent.

Sen. Elizabeth Warren, a Democrat, and Sen. Tim Scott, a Republican, co-authored the 21st Century ROAD to Housing Act. Warren said the measure would "boost housing supply, bring down costs, and – for the first time ever – stop private equity from buying up single-family homes."

"This bill will be the biggest housing bill in more than 30 years," Warren said. "We are in a full-blown housing crisis." Scott called its passage a "historic victory."

Enactment, however, is only the beginning of the law's rollout. The Urban Institute found that HUD must carry out 35 separate programs, regulations, and studies under the law, including developing best-practice resources for state and local zoning and land-use policies.

Severe understaffing and budget cuts at HUD, driven in part by Department of Government Efficiency (DOGE) initiatives, are raising concerns among lawmakers and housing advocates that implementation could be delayed.
