On July 11, 2026, the 21st Century ROAD to Housing Act became law after passing Congress with broad bipartisan support. The Senate passed the bill 85-5 and the following day the House passed the bill 358-32. The bill automatically became law on July 11, 2026 after President Trump neither signed nor vetoed it within the constitutional time limit.
The last time Congress passed a housing bill of this scale and significance was in 1990, representing the most significant congressional action on housing in more than three decades. The legislation is designed to expand homeownership opportunities by increasing housing supply, strengthening community development programs, and making homeownership more affordable and equitable for low- and moderate-income families and communities of color.
The law includes more than 50 sections addressing housing supply, financing, disaster recovery and other priorities. But as the Housing Wire article notes, outcomes depend on follow-through by states, cities, and industry. Enacting the 21st Century ROAD to Housing Act is only the beginning. Federal agencies must now move the law from passage to implementation, while Congress will need to fund several of its key initiatives.
The framework
What the law actually does
Incentives for local zoning reform, not federal mandates
The 21st Century ROAD to Housing Act will help increase the nation’s housing supply by reducing regulatory barriers and encouraging local governments to reform zoning and land-use policies that have limited home building. One reason the act has gained support is that it avoids preempting local zoning authority outright. Instead of overriding local control, the act focuses on research, guidance, and incentives for localities that choose to reform their zoning and regulatory frameworks.
The law’s official text is available on Congress.gov, where you can read the full 139-page statute designated as Public Law 119-101. The law’s stated purpose is “to increase the supply of housing in America, and for other purposes.”
The zoning reforms are largely nonbinding and the law repeatedly preserves state and local authority rather than preempting it. Some provisions, however, will have a more immediate effect. These include higher FHA multifamily loan limits and statutory environmental-review exemptions for qualifying affordable-housing projects.
The law’s major provisions
Updates statutory maximum loan limits for FHA multifamily mortgages and reforms the formula used to set them. Lifts the RAD program cap by 100,000 units and extends protections for tenants in RAD buildings. Eliminates the permanent chassis requirement for manufactured homes, establishes HUD as the primary authority on energy efficiency standards for manufactured homes, and requires HUD to establish minimum energy efficiency standards for manufactured homes. Expands eligible CDBG activities to include new construction of affordable housing, capped at 20 percent of a jurisdiction’s annual allocation.
Build Now
Cities get bonuses—or penalties—based on housing production
CDBG funding will be tied to how many homes you build, starting in 2029
The Build Now Act does something highly unusual in federal housing funding: It creates a tangible incentive for communities to build more housing. Unlike traditional federal housing grants, which are generally allocated to communities based on measures of need, the Build Now Act will reward communities that build more homes.
Under the law’s Build Now provision, which applies to cities and urban counties receiving CDBG entitlement funding, funding will be based on the rate at which housing has grown. Recipients at or above the median growth rate will receive bonuses, while recipients below the median generally will face a 10% reduction. Exemptions apply to municipalities that meet its thresholds for both lower rents and home values, places where rental vacancy rates are above the national average, areas recently impacted by a major disaster or emergency declaration within the previous three years, and those that lack legal authority to update zoning or permitting ordinances.
Because the bonus is financed entirely by reallocating existing CDBG funds, it comes at no additional cost to taxpayers. The Build Now Act applies only to jurisdictions with the most expensive housing, leaving the majority of the country untouched.
If you’re a first-time buyer in a high-cost city, this matters. Cities that want to avoid losing federal dollars will have a financial reason to approve more housing—which, over time, should ease the supply crunch that’s kept prices high.

Who qualifies for Build Now incentives
The housing increases can come from local governments and tribes reducing parking requirements, revising minimum lot sizes and building height, creating incentives for dense development, changing zoning laws, streamlining regulatory and environmental requirements, or eliminating restrictions on accessory dwelling units. Your city doesn’t have to overhaul its entire zoning code—any of these reforms count toward the production benchmark.
Multifamily financing
Higher FHA loan limits for apartments and small buildings
The first update to the formula since 2003
For those working with affordable housing or mixed-income multifamily properties, this provision matters. The law raises FHA multifamily mortgage insurance loan limits and reforms the formula going forward so that limits will better reflect current construction costs. HUD will also be required to evaluate the impact of these changes.
It could open the door to additional FHA-insured financing for multifamily projects that have been priced out of these programs for over two decades. If your ownership groups have been hesitant to pursue FHA financing due to outdated caps, it’s worth having that conversation now that the law is in effect.
For comparison, in 2026, the FHA loan limits for multifamily properties are: Two units: $693,063 in a low-cost area, $1,599,375 in a high-cost area; Three units: $837,720 in a low-cost area, $1,933,200 in a high-cost area; Four units: $1,041,138 in a low-cost area, $2,402,625 in a high-cost area. The new formula will adjust these limits annually using a Price Deflator Index, ensuring they keep pace with construction costs.
If you’re considering buying a duplex, triplex, or fourplex to live in one unit and rent out the others, FHA financing remains one of the most accessible options, requiring as little as 3.5% down. The updated limits mean more properties will qualify.
Institutional investors
New restrictions on bulk home buying
The ban takes effect in January 2027
The Final Bill retains the core prohibition from the Senate Bill: no “large institutional investor” – defined as a for-profit entity with direct or indirect investment control of 350 or more single-family homes – may purchase any single-family home after the effective date, subject to eleven enumerated excepted purchase categories. “Single-family home” continues to mean a structure containing two or fewer dwelling units intended for residential occupancy by a single household, excluding manufactured homes.
The 180-day implementation clock is now running, which means the institutional investor purchase restriction takes effect around early January 2027. The prohibition takes effect 180 days after enactment and is repealed 15 years after the effective date.
The ROAD to Housing Act caps single-family acquisitions by large investors but expands incentives and financing tools for housing supply and community development. The realignment is expected to accelerate build-to-rent, adaptive reuse, and affordable housing development, while limiting institutional bulk-buying of resale homes. Build-to-rent communities are explicitly carved out, meaning investors can still build new rental housing—they just can’t buy up existing homes in bulk.
For individual buyers, this could mean less competition from deep-pocketed investors when you’re bidding on a resale home. Learn more about making a competitive offer in today’s market.
Implementation
What happens next—and when
HUD has dozens of new programs to stand up
As part of the 21st Century ROAD to Housing Act, the US Department of Housing and Urban Development (HUD) is assigned at least 35 new programs, regulations, studies, and responses to congressional oversight. The 21st Century ROAD to Housing Act directs or authorizes federal agencies to establish more than a dozen new programs, including grant programs, pilots, and demonstrations. Some are mandated—with Congress directing a federal agency to establish the programs, typically within a specific timeframe. Other sections of the law simply grant the relevant agency new authority without a requirement to act. Importantly, nearly all these programs will depend on future congressional appropriations to operate.
Until then, local governments can expect many opportunities to weigh in on program implementation as proposed rules are made public over time. The intent of many new programs and resources are aimed at incentivizing and assisting local governments to rethink and reform local land use ordinances in the belief that such federal-local partnerships will produce more attainable housing more quickly than pre-emptions or mandates.
But there is much more to be done. Realizing the promise of the act will depend on thoughtful implementation by HUD, states, local governments, lenders, manufacturers, and other partners. Even if all the bill’s provisions are implemented, it will not, on its own, significantly reduce price pressures. States and local governments still must reform their restrictive systems.
For buyers, the takeaway is simple: this law creates new tools and incentives, but it won’t lower home prices overnight. The real impact will unfold over the next several years as cities respond to the new funding formulas, HUD issues guidance, and developers use the updated FHA limits to finance more projects. If you’re buying your first home, the fundamentals haven’t changed—get pre-approved, understand the closing process, and shop for the best rate.
Key deadlines to watch
HUD must report to Congress annually for five years, beginning two years after enactment (July 11, 2028). Requires FHA to calculate and publish annual adjustments using a Price Deflator Index, starting July 1, 2025 (predating enactment). Requires FHA to conduct a study on multifamily loan limits relative to current market conditions prior to reporting findings to Congress within three years of enactment (July 11, 2029). Creates a new $200 million annual Innovative Housing Growth Grant Program for cities, counties, and tribes that increase housing supply.
Quick answers
21st Century ROAD to Housing Act: common questions
When did the 21st Century ROAD to Housing Act become law?
The law took effect on July 11, 2026, after President Trump neither signed nor vetoed it within the 10-day constitutional window. The Senate passed it 85-5 on June 22, and the House passed it 358-32 on June 23. It is the first comprehensive federal housing legislation enacted since 1990.
Does the law force cities to change their zoning?
No. The law does not preempt local zoning authority. Instead, it offers financial incentives (through CDBG bonuses) for cities that increase housing production and provides HUD guidance on best practices. Cities retain full control over their zoning codes, but starting in 2029, those that fail to build housing at the median rate may see a 10% reduction in federal block grant funding.
What does this mean for FHA multifamily loans?
The law updates the FHA multifamily loan limit formula for the first time since 2003. Limits will now be adjusted annually using a Price Deflator Index to reflect current construction costs. For 2026, FHA multifamily limits range from $693,063 (two units, low-cost area) to $2,402,625 (four units, high-cost area). The updated formula should make FHA financing more accessible for small apartment buildings and duplexes.
Can institutional investors still buy homes?
Starting in January 2027 (180 days after enactment), large institutional investors—defined as entities controlling 350 or more single-family homes—will be prohibited from purchasing existing single-family homes and duplexes. The ban includes 11 exceptions, most notably for build-to-rent communities (new construction). Individual investors and smaller firms are not affected. The restriction sunsets after 15 years.
Will this law lower home prices?
Not immediately. The law creates incentives for cities to approve more housing and removes some regulatory barriers, but it does not inject new capital into construction or provide large-scale subsidies. Experts note that even if all provisions are implemented, states and cities must still reform their zoning and land-use systems. The impact on prices will depend on how many new homes are actually built over the next several years.
What programs need funding from Congress?
Nearly all the new programs authorized by the law—including the $200 million Innovation Fund, point-access block building grants, small-dollar mortgage pilots, and disaster recovery initiatives—depend on future congressional appropriations. Some provisions, like the FHA loan limit updates and NEPA streamlining, are self-executing and do not require additional funding.
