The 21st Century ROAD to Housing Act Is Now Law. Here’s What Actually Changed.

The 21st Century ROAD to Housing Act Is Now Law

On July 11, 2026, the 21st Century ROAD to Housing Act officially became law through an unusual constitutional process. Rather than signing or vetoing the legislation, President Donald Trump allowed the ten-day review period provided under Article I, Section 7 of the U.S. Constitution to expire. Although he had initially hoped Congress would first approve an unrelated voting measure, that never materialized, and the housing legislation automatically took effect without presidential action.

The bill’s path to enactment was almost as remarkable as the legislation itself. While major federal reforms often delayed in partisan conflict, the ROAD to Housing Act attracted overwhelming bipartisan support. The Senate approved the measure by an 85–5 vote on June 22, followed by a decisive 358–32 vote in the House the next day. Such broad consensus has become increasingly uncommon in Washington and reflects months of negotiation between lawmakers from both parties.

The legislation was shaped largely through the collaborative efforts of Senator Elizabeth Warren (D–Massachusetts), Senator Tim Scott (R–South Carolina), Representative Maxine Waters (D–California), and Representative French Hill (R–Arkansas). After more than a year of discussions and revisions, they successfully reconciled competing House and Senate proposals into a single bipartisan package. The result is a landmark housing reform that many analysts regard as the most consequential federal housing legislation since the Cranston-Gonzalez National Affordable Housing Act of 1990.

Why Congress bothered

Although experts differ on the exact scale of the United States’ housing shortage, there is broad agreement that the country faces a serious supply challenge. Estimates vary considerably, with Moody’s suggesting a deficit of around 2 million homes, while White House projections place the shortfall as high as 10 million. Other organizations, including Realtor.com, Zillow, the Brookings Institution, and McKinsey, have published figures that fall somewhere between these estimates. These differences largely stem from the methods used to calculate housing demand, particularly whether researchers include households that were never established because rising housing costs prevented people from leaving shared or family living arrangements.

Despite the variation in the numbers, there is little disagreement about the underlying issue. Over the past two decades, housing prices have risen much faster than household incomes, making homeownership increasingly difficult for many Americans. At the same time, lengthy permitting procedures, restrictive zoning regulations, and limited access to development financing have constrained the construction of new homes. The 21st Century ROAD to Housing Act seeks to address these structural barriers by encouraging additional housing development and improving the policies that shape the nation’s housing supply.

Cutting the red tape for builders

One of the primary objectives of the 21st Century ROAD to Housing Act is to reduce administrative and regulatory barriers that often delay housing projects before construction can even begin. By simplifying approval procedures and encouraging more efficient planning practices, the legislation aims to accelerate the delivery of new housing across the country.

Reforms to Environmental Reviews: The Act broadens the use of categorical exclusions under the National Environmental Policy Act (NEPA), allowing many smaller residential developments, infill housing projects, and most infill initiatives supported by the Rural Housing Service to proceed without undergoing lengthy environmental assessments. This change is intended to shorten project timelines while maintaining appropriate environmental safeguards.

Standardized Building Designs: To help local governments expedite project approvals, the legislation authorizes federal funding for the adoption of standardized, pre-approved architectural designs, commonly referred to as pattern books. By relying on designs that have already been reviewed, developers can reduce repetitive design evaluations and move projects through the permitting process more efficiently.

Housing Innovation Fund: The Act establishes a competitive grant program valued at $200 million annually for the period 2027 through 2031. The program provides financial incentives to states and municipalities that demonstrate measurable progress in increasing housing supply. Qualifying initiatives may include streamlining permitting procedures, reducing or eliminating minimum parking requirements, permitting accessory dwelling units (ADUs), or introducing zoning policies that support mixed-income residential development. The program is scheduled to expire after seven years unless renewed by Congress.

Model Zoning Frameworks: The Department of Housing and Urban Development (HUD) is required to develop model zoning guidelines and recommend state-level appeal mechanisms for developers whose zoning variance requests are denied by local authorities. These recommendations are advisory rather than mandatory. The Act preserves local control over zoning decisions and does not authorize HUD to override or penalize jurisdictions that choose not to adopt the proposed frameworks.

A refresh for manufactured and modular housing

The 21st Century ROAD to Housing Act introduces several reforms aimed at lowering construction costs and encouraging the broader adoption of manufactured and modular housing solutions. One of the most significant changes is the removal of the longstanding federal requirement that manufactured homes be built on a permanent steel chassis. Policymakers concluded that the decades-old regulation increased construction costs without delivering meaningful improvements in safety or structural performance.

The legislation also directs the U.S. Department of Housing and Urban Development (HUD) to modernize its construction financing procedures for modular housing projects. Specifically, HUD must revise its funding disbursement schedules so that payments better reflect the way modular homes are manufactured, transported, and assembled. This adjustment is expected to improve cash flow for builders and reduce financing challenges during construction.

In addition, the Act establishes a federal framework for point-access block buildings residential buildings of up to six stories that rely on a single central staircase for access. While this design is widely used in many European countries to improve space efficiency and reduce construction costs, existing building code requirements have limited its use across much of the United States. Under the new law, HUD is authorized to develop permitting guidance and support pilot projects to evaluate the feasibility, safety, and potential benefits of these building designs before they are adopted on a broader scale.

Where the money moves

The 21st Century ROAD to Housing Act introduces a series of financial measures designed to improve access to capital for developers, lenders, local governments, and public housing agencies. These provisions seek to stimulate affordable housing development by increasing funding flexibility and encouraging greater private-sector participation.

The Act broadens the allowable use of Community Development Block Grant (CDBG) funds, enabling recipients to finance the construction of new affordable housing in addition to rehabilitation and maintenance projects. To improve transparency and encourage development, grant recipients are also required to maintain publicly accessible inventories of undeveloped land under their ownership that may be suitable for future housing projects.

For the first time in nearly three decades, the HOME Investment Partnerships Program has been substantially updated. The legislation increases the income eligibility threshold to 100% of the Area Median Income (AMI), allowing the program to support a broader segment of the workforce and better address the growing demand for affordable housing among middle-income households.

To unlock additional private investment, the Act raises the public welfare investment limit for eligible financial institutions from 15% to 20%. This expanded investment capacity is expected to channel more capital into affordable housing initiatives and community development projects.

The legislation strengthens housing opportunities in rural communities by permanently separating Section 521 Rental Assistance from expiring rural mortgage agreements, ensuring continued support for eligible tenants. It also launches a pilot program for small-dollar mortgages valued at $100,000 or less, a financing segment that has seen limited participation from traditional lenders due to low profitability.

Several measures provide housing authorities with additional operational flexibility. The cap on the Rental Assistance Demonstration (RAD) program is increased by 100,000 units, authorization for CDBG Disaster Recovery funding is extended for three years, and a new Moving to Work cohort allows participating housing agencies to test innovative local strategies for improving housing delivery and management.

The corporate-landlord crackdown

One of the most widely discussed provisions of the 21st Century ROAD to Housing Act focuses on reducing the growing influence of large institutional investors in the single-family housing market. Through the “Homes Are for People, Not Corporations” initiative, the legislation generally prohibits large for-profit organizations that directly or indirectly control 350 or more single-family homes from purchasing additional existing single-family residential properties. For the purposes of this provision, a single-family home includes properties containing no more than two residential units. Manufactured homes, multifamily apartment buildings, and properties owned by government agencies are excluded from this calculation.

To prevent investors from avoiding these restrictions through complex ownership arrangements, the Act adopts a broad definition of control. An organization may be considered to control a property if it holds legal ownership, exercises primary investment or management authority, manages the investment fund or partnership that owns the property, serves as its investment manager or advisor, or possesses more than 25 percent ownership in the entity holding title, provided that such ownership is not solely passive in nature. These provisions are intended to enhance transparency and discourage the use of shell companies or layered corporate structures to circumvent the legislation.

The Act does, however, recognize the importance of encouraging new housing development. As a result, several exceptions have been incorporated into the legislation. Institutional investors remain eligible to finance and develop build-to-rent (BTR) communities, renovate-to-rent projects, and age-restricted senior housing developments designed for residents aged 55 years and above.

The underlying policy objective is to support investments that expand the nation’s housing supply rather than those that compete directly with individual homebuyers for existing residential properties.

The seven-year rule that almost happened — but didn’t

One of the most significant changes made during the legislative process involved the treatment of build-to-rent (BTR) developments. The version of the bill initially approved by the Senate in March 2026 included a requirement that institutional investors relying on the BTR exemption sell each property to an individual homeowner within seven years of acquisition. In addition, tenants were to be granted a 30-day first opportunity to purchase the property, along with a right of first refusal before it could be sold to another buyer.

Critics argued that imposing a mandatory resale deadline would undermine the financial viability of long-term rental communities by reducing investment certainty. They also highlighted the practical challenges of selling individual homes within large rental developments, particularly where multiple properties are located on a single parcel of land. In many cases, this process would require land subdivision or condominium conversion, both of which are subject to local planning approvals that may not be readily available. During this period of uncertainty, Terra Lane Communities reportedly paused several projects in Arizona and Texas, while representatives of the National Association of Home Builders (NAHB) maintained that removing these provisions would restore confidence among residential developers.

The proposed restrictions also attracted attention at the White House. Reports indicated that President Donald Trump considered publicly criticizing the seven-year resale requirement but instead chose to allow further negotiations between his administration and House Republican leaders. These discussions ultimately influenced the House amendments introduced in May 2026 by Representatives French Hill and Maxine Waters, which removed the mandatory seven-year resale requirement as well as the automatic tenant first-look and right-of-first-refusal provisions associated with the build-to-rent exemption.

As enacted, the 21st Century ROAD to Housing Act no longer requires investors participating in qualifying build-to-rent projects to dispose of their properties within a specified timeframe. Instead, eligible properties may be retained as long-term rental assets, providing greater investment certainty while preserving the Act’s objective of encouraging the construction of new housing rather than restricting its development.

Although the mandatory purchase rights for tenants were removed from the final legislation, they were not eliminated entirely. Similar provisions continue to exist within separate voluntary federal programs that are intended to help renters strengthen their financial position, build credit histories, and transition toward homeownership over time, rather than applying automatically to every build-to-rent development.

What renters still get

Even without the disposition deadline, the law adds a few protections for people renting from large institutional landlords. HUD has to stand up a toll-free number and public website where renters of investor-owned homes can raise disputes, and landlords have to notify tenants about it in writing every year. Separately, any entity that meets the 350-home threshold has to report its status to the Treasury Secretary annually and disclose how many homes it controls and where regardless of whether it bought anything new that year.

Enforcement has real teeth

The Treasury Secretary, or the Attorney General acting on the Secretary’s behalf, can sue an investor who breaks the rules for a civil penalty of whichever is greater: $1,000,000 per violation, or three times the purchase price of the home involved. Money collected from those penalties doesn’t disappear into the general fund it’s routed to HUD’s HOME Investment Partnerships program, earmarked for building, acquiring, and rehabbing single-family homes, plus down-payment, closing-cost, and rate-buydown assistance for first-time buyers.

Will it actually fix housing?

The 21st Century ROAD to Housing Act represents one of the most comprehensive federal housing reform packages introduced in decades. With more than 50 individual provisions addressing issues ranging from zoning reform and development financing to manufactured housing and institutional investment, supporters argue that the legislation demonstrates a renewed federal commitment to tackling the nation’s housing affordability challenges. By combining regulatory reforms with targeted financial incentives, the Act seeks to remove long-standing barriers that have limited the supply of new housing.

However, some housing policy experts remain cautious about the legislation’s potential impact. Analysts have pointed out that large institutional investors account for only a relatively small share of the overall single-family housing market, suggesting that restrictions on corporate ownership alone are unlikely to significantly improve housing affordability. Others note that, while initiatives such as the $200 million annual Innovation Fund provide meaningful support for housing development, the available funding may be modest when compared with a national housing shortage estimated to be in the millions of homes.

Perhaps the most significant limitation of the Act is that it preserves local authority over land-use and zoning decisions. Rather than imposing federal zoning requirements, the legislation relies on incentives to encourage state and local governments to adopt housing-friendly policies. Programs such as the Innovation Fund, standardized building plan grants, and HUD’s model zoning guidance are entirely voluntary. As a result, the long-term success of the Act will depend not only on federal implementation but also on the willingness of cities, counties, and municipalities to embrace the reforms and expand housing opportunities within their own jurisdictions.

Ultimately, while the 21st Century ROAD to Housing Act is unlikely to resolve America’s housing affordability crisis on its own, it establishes a significant policy framework for increasing housing supply and modernizing federal housing programs. Its effectiveness will become clearer over time as local governments, developers, and financial institutions respond to the incentives and opportunities created by the legislation.
