The housing affordability bill: what was in it and why it stalled

01What the housing bill proposed

The housing affordability bill proposed a comprehensive set of measures designed to address the affordable housing crisis, which has left approximately 7.3 million American households spending more than half of their income on rent. The bill's core provisions included expanded funding for the Housing Choice Voucher program (Section 8), a new federal rent subsidy for households earning below 30% of area median income, a $10 billion investment in the Low-Income Housing Tax Credit (LIHTC) program, and grants to states and municipalities that reformed zoning to allow denser development.

The bill also proposed a federal framework for rent stabilization, limits on annual rent increases for tenants in subsidized housing, and the creation of a national housing trust fund modeled on existing state-level programs. The total cost was estimated at $150 billion over ten years — modest by the standards of recent infrastructure and climate legislation but significant for a housing bill. The Congressional Budget Office scored the bill and confirmed its cost estimates, but the political path to passage proved more challenging than the fiscal one.

02The political divide on housing policy

The bill exposed a political fault line that does not map neatly onto partisan divisions. Republicans broadly opposed the bill's expansion of federal authority over housing, arguing that zoning and land-use decisions are properly local matters. Some Democrats from high-cost coastal districts supported the bill's subsidy provisions but objected to the zoning reform requirements, which would have overridden local zoning in their districts. The result was a coalition in favor of the bill that was broad but shallow, and an opposition that was narrow but deep.

The administration's refusal to sign the bill — or more precisely, the threat of a veto that prevented it from reaching the floor in a form acceptable to its sponsors — was rooted in several objections. The bill's rent stabilization provisions were characterized as "rent control by another name," a charge that carries political weight given the controversial history of rent regulation. The zoning reform requirements were framed as federal overreach. And the overall cost was cited as excessive at a time of fiscal consolidation. These objections were sufficient to stall the bill despite broad public support for housing affordability measures.

03Rent control and its controversial history

Rent control (or rent regulation) is a system of laws for the rental market of dwellings, with controversial effects on affordability of housing and tenancies. Generally, a system of rent regulation involves price controls — limits on the rent that a landlord may charge, typically called rent control or rent stabilization — and eviction controls: codified standards by which a landlord may terminate a tenancy. The first rent control laws in the United States were enacted during World War I, and the policy has been politically contentious ever since.

Economists have historically been skeptical of rent control. A widely cited 1992 survey found that 93% of economists agreed that rent ceilings reduce the quality and quantity of housing available. More recent research has produced a more nuanced picture: studies of San Francisco's 1994 rent control expansion found that it benefited covered tenants but reduced the rental housing supply by 15%, as landlords converted units to condominiums or removed them from the market. The bill's sponsors attempted to address these concerns by limiting rent stabilization to buildings receiving federal subsidies, but critics argued that the precedent would inevitably expand.

04Zoning reform and NIMBY resistance

In urban planning, zoning is a method in which a municipality or other tier of government divides land into land-use and building zones, each of which has a set of regulations for new development that differs from other zones. Single-family zoning, which covers the majority of residential land in most American cities, has been identified by economists and housing advocates as a primary driver of housing unaffordability. By restricting the supply of housing, single-family zoning drives up prices and excludes lower-income residents from desirable neighborhoods.

The bill's zoning reform provisions would have required states and municipalities receiving federal housing funds to allow multifamily housing by right in areas near transit stations and in neighborhoods currently zoned exclusively for single-family homes. This provision encountered fierce resistance from local homeowners' associations and NIMBY (Not In My Back Yard) groups, who argued that denser development would change neighborhood character, strain infrastructure, and reduce property values. Research has consistently found that these concerns are overstated — denser development near transit increases property values and reduces per-capita infrastructure costs — but the political power of existing homeowners remains the primary obstacle to zoning reform.

05Federal housing subsidies explained

The federal government's role in housing affordability is primarily fiscal rather than regulatory. The Housing Choice Voucher program (Section 8) is the largest federal housing subsidy, serving approximately 2.3 million households at an annual cost of approximately $35 billion. Vouchers allow low-income tenants to rent housing in the private market, with the government paying the difference between 30% of the tenant's income and the fair market rent. Despite its size, the program reaches only about one in four eligible households due to funding limitations.

The Low-Income Housing Tax Credit (LIHTC) is the second-largest federal housing program, providing approximately $14 billion annually in tax credits to developers who build or rehabilitate affordable housing. The program has financed over 3.7 million affordable housing units since its creation in 1986, but critics note that many LIHTC units are not affordable to the lowest-income households, and the program's complexity means that a significant portion of the subsidy is consumed by intermediaries rather than reaching tenants. The bill proposed reforms to both programs, including expanding voucher eligibility and simplifying the LIHTC structure.

06The role of local vs federal government

The tension between local and federal authority is the structural issue underlying American housing policy. Local governments control zoning, land use, and building codes — the primary determinants of housing supply. Federal funding is necessary but not sufficient: subsidies can increase purchasing power, but if local zoning prevents new construction, the result is higher rents rather than more housing. This is why the bill's zoning reform provisions were its most innovative and most controversial element.

Several states have taken zoning reform into their own hands. California's SB 9, enacted in 2021, allowed lot splits and duplex construction in single-family zones statewide. Oregon's 2019 legislation effectively banned single-family zoning in cities with populations over 10,000. These state-level reforms have produced mixed results — permitting has increased but not as dramatically as proponents hoped, and implementation has been slow. The bill's approach of conditioning federal funding on local reform would have accelerated this process, but it also raised constitutional questions about federal authority over traditionally local matters.

07What happens without legislative action

Without legislative action, the housing affordability crisis will continue to worsen. The Joint Center for Housing Studies at Harvard University reported in 2025 that a record 22.4 million renter households are cost-burdened — spending more than 30% of income on housing — and 12.1 million are severely cost-burdened, spending more than half. Homelessness has increased in major cities, and the gap between housing costs and wages continues to widen. The market alone will not solve the problem: the profit-maximizing strategy for landlords in constrained markets is to raise rents, not to build new supply.

In the absence of federal action, states and cities are experimenting with their own solutions. Denver, Minneapolis, and Austin have enacted zoning reforms. California has invested billions in affordable housing through state bond measures. But these local efforts are fragmented, underfunded, and vulnerable to local political reversal. The housing affordability bill represented the most comprehensive federal housing legislation in decades, and its failure leaves the problem to a patchwork of state and local programs that have demonstrably failed to keep pace with the scale of the crisis.
