Why It Matters
After months of negotiations, Congress enacted a sweeping housing package that substantially changed the legislation the House initially approved. These differences matter for housing developers, federal agencies, and congressional staff as they determine which proposed reforms became law.
The House-passed Housing for the 21st Century Act addressed housing supply, federal programs, and banking rules across six titles and 38 sections, but Congress ultimately enacted a version that differs from what the House approved, according to a Congressional Research Service (CRS) report.
The report primarily analyzes the pre-enactment bill and directs readers to CRS Report R49354 for analysis of P.L. 119-101, the 21st Century ROAD to Housing Act, which became law July 11 without the president's signature. Five House provisions, Sections 406, 603, 607, 608, and 613, have no corresponding sections in the enacted law. Congress enacted two veterans-income provisions separately on Jan. 20 as the Disabled Veterans Housing Support Act (P.L. 119-70).
The Big Picture
Of the House-passed bill's 38 sections, 25 were in Titles I through V. Those titles addressed housing supply rules, reforms to the HOME Investment Partnerships program, the Community Development Block Grant, the Section 504 rural housing home repair program and the Housing Choice Voucher program, manufactured housing, small-dollar mortgages, borrower protections, and congressional oversight of federal housing officials and public housing agencies. Title VI, which added 13 banking-related sections, was not in the committee-reported version and appeared in the House-passed bill.
On environmental review, some stakeholders have argued that such reviews add costs and delays to housing development, while others argue they are necessary to protect the environment and human health. On single-stair buildings, proponents suggest reforms "would reduce construction costs," while the National Fire Protection Association and other organizations have cautioned that double stairwells remain necessary for fire safety.
The report includes a side-by-side comparison of the House bill and the ROAD to Housing Act of 2025 (S. 2651), sponsored by Sen. Tim Scott (R-SC), noting that some sections are substantially identical, others differ notably, and some provisions appear in only one bill. The Senate Banking, Housing and Urban Affairs Committee reported S. 2651 on Aug. 1, 2025. The Senate later used the bill as a basis for provisions considered in broader housing legislation.
The Senate passed H.R. 6644 with substitute amendment S.Amdt. 4308 on March 12 by an 89-10 vote. After further negotiations and amendments between the chambers, the House agreed to the final compromise on June 23 by a 358-42 vote.
The Bottom Line
Since the enacted law differs from the House-passed bill, practitioners and congressional staff tracking implementation must consult P.L. 119-101 rather than the earlier version of H.R. 6644 to determine what is now operative. Three companion bills cited for similar provisions, S. 2391, S. 2414, and S. 2423, were introduced separately.
