The biggest federal housing bill in a generation is now law — it took effect July 11, without Trump's signature.

Congress doesn't agree on much these days. The 21st Century ROAD to Housing Act — H.R. 6644 — passed the Senate 85-5 and the House 358-32 in late June 2026. Those vote margins aren't a typo. This was one of the most bipartisan majorities in recent congressional memory, on any subject.

An unusual path to becoming law

President Trump had a signing ceremony scheduled for June 23. He canceled it the same day, posting that he was conditioning action on Congress first passing the SAVE Act — separate legislation focused on election procedures. The bill was formally presented to Trump on June 29. Under Article I of the Constitution, the president has ten days (excluding Sundays) to sign or veto before a bill becomes law by default when Congress remains in session. That constitutional clock expired at midnight on July 10–11. The bill became law at 12:01 a.m. on July 11, 2026 — automatically, without a presidential signature. House Speaker Mike Johnson had publicly confirmed Trump would not veto.

85-5 in the Senate. 358-32 in the House. It became law anyway.

The institutional investor restriction

The provision that got the most public attention: large institutional investors — funds, REITs, or corporations that already own more than 350 single-family homes — are prohibited from purchasing additional single-family properties. The law carves out exceptions for build-to-rent communities (new construction purpose-built for rental) and manufactured homes. A new HUD renter outreach resource is established for tenants in institutional-investor-owned properties. For context: California's own AB 1240 — authored by Assemblymember Alex Lee, which would have set the cap at 1,000 homes — died in the State Senate in June 2026, killed partly by fellow Democrats who worried about the impact on build-to-rent development. The federal threshold is stricter: 350 homes, not 1,000.

For Bay Area and Solano County buyers: firms like Invitation Homes and Progress Residential, which typically hold tens of thousands of units nationally, are very likely already above the 350-home threshold across their California portfolios. The purchase ban takes effect January 7, 2027 — 180 days from the law's July 11, 2026 enactment. No divestiture of existing holdings is required; the law prohibits new acquisitions only after that date. In practice, the provision's real-world bite will also depend on enforcement by HUD and state attorneys general, and whether build-to-rent exceptions get used as a workaround for what was previously a direct-purchase strategy.

The zoning reform piece — models, not mandates

The other major supply-side provision is less flashy but potentially durable: the law directs HUD to develop and publish model state enabling legislation for local zoning reform. The models cover increases in maximum floor-area ratios and building heights, reductions in minimum lot sizes and setback requirements, and authorization of duplexes, triplexes, and quadplexes as by-right uses across residential zones. States and cities are not required to adopt these models — but they now exist as a federally-endorsed framework, with HUD technical assistance attached. For California, which has already gone further through SB 9, SB 79, and related state laws, this federal layer is less transformative. For states without California-style state housing mandates, the federal models are a more significant tool.

Affordable housing programs: RAD, CDBG-DR, and the HOME Act

The bill expands several federal affordable housing programs directly relevant to Solano County and the broader Bay Area. The cap on the Rental Assistance Demonstration (RAD) program — which converts aging public housing to privately managed, Section 8-funded housing — is raised by 100,000 units. Vallejo has aging public housing stock that has been evaluated for RAD conversion; this expansion makes the federal program more available for cities competing for it. The Community Development Block Grant — Disaster Recovery (CDBG-DR) program is re-authorized for three years, providing a dedicated federal funding vehicle for communities recovering from presidentially-declared disasters — relevant to Solano neighbors recovering from North Bay wildfire events. And Congressman Garamendi's own HOME Act provision is included in the package, directing resources toward affordable housing production and preservation.

Local angle: Garamendi and the Solano connection

Congressman John Garamendi — whose district covers all of Solano County and parts of Contra Costa — held a press conference in El Cerrito on July 7, 2026 calling on Trump to sign the bill. His HOME Act provision, which he authored and successfully included in the package, focuses specifically on affordable housing production. The legislation's passage also fits into the broader pattern of Garamendi using federal legislative vehicles to direct investment into the district — the SHIPS for America Act and federal maritime investment in Mare Island and the Suisun Bay shipyard are on a parallel track.

My read for clients: the institutional investor provision matters most in markets where large corporate landlords have been active buyers — Antioch, Pittsburg, Richmond, Vallejo's entry-level single-family tier. The ban on new acquisitions by firms holding 350+ homes kicks in January 7, 2027 — not today. Between now and then, those buyers remain fully active. After January 7, if enforcement is real, some of the all-cash corporate competition that has been suppressing inventory at the low end comes off the board. The zoning models matter less here in California, where state law already does more. The RAD expansion is worth watching for Vallejo specifically. If you're a buyer who's been losing to cash offers from institutional players in Solano or East Bay markets, mark that date — and ask me who's been buying in the specific zip codes you're watching.
