In a political landscape often paralyzed by gridlock, a quiet but potent shift is underway: a bipartisan coalition in the House is finally treating housing not as a cultural wedge issue, but as a supply-side economic imperative. Matthew Yglesias identifies a growing faction, the Build America Caucus, that is moving beyond rhetoric to attach pro-building incentives to the very machinery of federal funding, offering a rare glimpse of functional governance in a broken system.
The Rise of the Build America Caucus
Yglesias opens by highlighting the strategic evolution of this group, noting that while it began with a modest goal, its influence is expanding. "The Build America Caucus is growing," he observes, pointing to its launch in May 2025 by Representative Josh Harder and its rapid expansion to over 40 members. The caucus's distinctiveness lies in its refusal to let ideology dictate housing policy; instead, it pairs conservative leadership with centrist Democrats to pursue "abundance" themes. As Yglesias writes, the group focuses on "addressing America's housing, infrastructure, and energy issues by implementing supply side reforms."
This framing is crucial. It sidesteps the usual partisan shouting match over who is to blame for high rents and instead asks a pragmatic question: how do we build more? The caucus is effectively doing the coordinating work to build a cross-partisan bloc that can attach itself to vehicles like appropriations bills or the National Defense Authorization Act when the opportunity arrives. This mirrors the legislative strategy seen in the NDAA, where defense spending has long been used as a vehicle for unrelated policy wins. Here, housing reform is being woven into the fabric of federal spending, leveraging the threat of withholding funds to encourage local change.

Critics might note that 40 members in a 435-member House is still a minority, and the Republican majority has its own deregulatory priorities that don't necessarily run through bipartisan caucuses. However, Yglesias argues that the real power lies in the mechanism: "They cite boosting project applications to the Capital Investment Grants program that would pressure local governments to allow more housing to be built near transit." By tying federal dollars to pro-housing behavior, the caucus attempts to bypass the taboos surrounding local zoning authority without explicitly preempting it.
The Human Cost of Policy Failures
While the caucus looks forward, Yglesias pivots to the stark reality of current policy failures, where well-intentioned crackdowns and ideological shifts are causing genuine human suffering. He details a disturbing situation in Minnesota, where a fraud crackdown in Medicaid-funded disability programs has inadvertently stripped housing from vulnerable residents. "One unintended consequence of Minnesota's effort to crack down on fraud... is that people with disabilities are losing their housing," Yglesias reports. The state withheld payments from providers, creating an "existential threat to the care infrastructure that keeps Minnesotans with disabilities safe, housed, and supported."
The evidence here is chilling. While fraud is real—evidenced by cases involving AI-generated fake records and men pleading guilty to defrauding the system of millions—the blanket suspension of payments has punished the innocent alongside the guilty. This highlights a critical flaw in the current approach: the lack of nuance in enforcement. The administration's focus on fiscal purity is colliding with the reality of a fragile social safety net.
A similar dynamic is playing out in Chicago, where the Department of Housing and Urban Development (HUD) is shifting funding away from "Housing First" models. "HUD has signaled it will cap the share of Continuum of Care grants that can go to permanent housing, potentially cutting thousands of units," Yglesias notes. The administration defends this by claiming a desire to measure success by "self-sufficiency and recovery," but the result is a crisis in cities like Chicago, where 60 percent of permanent supportive housing relies on federal funds. This move ignores decades of evidence suggesting that stable housing is a prerequisite for recovery, not a reward for it.

State and Local Experiments in Abundance
Despite federal headwinds, Yglesias highlights a wave of innovation at the state and local levels, where the pressure of the housing crisis is forcing bold, sometimes controversial, experiments. In Michigan, a bipartisan group introduced a "Housing Readiness Package" to allow duplexes in single-family zones and reduce lot size requirements. The urgency is clear: "Michigan's housing production has fallen sharply from roughly 54,000 units annually in 2005 to about 15,000 in 2024," driving severe affordability pressures. Yet, even here, the debate is fierce, with the Michigan Municipal League arguing that local rules play a "relatively small part" in housing costs.
Perhaps the most striking example of desperation is a bill in Michigan that would allow people to live in campgrounds for more than six months. While supporters cite the need to house workers like linemen and nurses, opponents warn that campground infrastructure isn't designed for year-round occupancy. "The bill... would allow indefinite stays at campgrounds within 50 miles of communities that face housing shortages," Yglesias explains. This proposal underscores the severity of the shortage: when camping becomes a viable housing strategy, the system has failed.
In contrast, Chicago's "Missing Middle" program offers a more traditional, yet highly effective, model. The city is selling vacant lots for $1 and providing subsidies to build multi-unit homes in neighborhoods that have suffered decades of disinvestment. "The model prioritizes owner-occupied, neighborhood-scale infill over high-rise rentals," Yglesias writes, noting that the initiative is advancing workforce homeownership in areas where investment is needed most. Similarly, in Maryland, Anne Arundel County passed legislation to allow "cottage homes"—tiny dwellings of 800 square feet or smaller—creating a density bonus that could make these units financially viable for buyers earning at or below the area median income.

The Industrial Revolution of Homebuilding
Yglesias concludes by looking at the most transformative potential solution: industrializing homebuilding. In California, the "Year of the Housing Factory" is upon us, with Assemblymember Buffy Wicks leading a push to support off-site construction. "Factory-built (modular and prefabricated) housing is gaining real momentum in California after decades of false starts," he reports. The urgency has been amplified by the Los Angeles wildfires, where modular homes have allowed survivors to move in within months.
This is not the first attempt at such a revolution. Yglesias reminds readers of "Operation Breakthrough in the 1970s and the 2021 collapse of Silicon Valley start-up Katerra after it burned through $2 billion." Yet, he argues that the conditions are different now. "Proponents argue that this time, the market conditions, labor shortages, and political will are different." The policy levers under consideration include insuring factories against risk and reducing differences in building code requirements across jurisdictions. If successful, this could fundamentally alter the economics of housing, turning it from a slow, artisanal process into a scalable industry.
In northern Maine and Memphis, similar themes of leveraging private capital and adaptive reuse are emerging. Memphis Mayor Paul Young has pledged to add 10,000 homes by 2030, a goal that, while not closing the gap, signals a "significant scaling-up of ambition." The plan centers on liberalizing zoning, streamlining approvals, and using city-owned land, relying on private capital rather than direct tax dollars. This shift from public funding to public-private partnership is a recurring theme in Yglesias's analysis, suggesting that the future of housing reform lies in unlocking market forces rather than waiting for government handouts.
Bottom Line
Matthew Yglesias makes a compelling case that the path to housing abundance lies in a pragmatic, supply-side coalition that transcends traditional partisan divides. The strongest part of his argument is the identification of the Build America Caucus as a potential engine for change, using the leverage of federal funding to nudge local behavior without triggering a constitutional crisis. However, the biggest vulnerability remains the inherent tension between federal incentives and local autonomy, a dynamic that has stalled reform for decades. The reader should watch closely to see if this new coalition can survive the next appropriations cycle and whether the industrialization of homebuilding can finally overcome the historical failures that have plagued the sector.
The practical track record of federal incentive programs over the years is decidedly mixed, but the current political moment may finally be different.
