Key Business Provisions in the 21st Century ROAD to Housing Act

The 21st Century ROAD to Housing Act (H.R. 6644) became law on July 11, 2026, after clearing Congress with rare bipartisan support. The new law reshapes who can buy homes, how fast builders can break ground, and where housing money flows next. Its provisions are aimed mostly at state and local governments, but the effects will soon reach businesses tied to construction, investment, and federal housing finance. Leaders in these industries will want to understand the timeline ahead and how it may influence future projects and investment decisions. To help clients, prospects, and others, Wilson Lewis has summarized the key details below.

Background

The United States continues to face a housing shortage, with most estimates putting the gap at around 4 million housing units. To put that into perspective, the country currently builds roughly 1.4 million housing units per year, meaning it would take nearly three years of nationwide construction just to close the existing gap.

In response, Congress negotiated a mix of financing reforms, regulatory changes, and development incentives to increase housing production over time. The law adds no new direct funding for housing. Instead, many provisions reward communities that increase housing supply, so implementation will vary by jurisdiction. Analysts expect the law to make homeownership more accessible over time, but caution that the effects will take years rather than months to be realized.

Key Provisions of the Housing Law 

The legislation includes dozens of housing-related provisions. Below are several of the most significant changes affecting businesses, investors, developers, lenders, and others.

• Homes Are for People, Not Corporations — Beginning 180 days after enactment, large institutional investors, defined as for-profit entities with ownership or investment control over 350 or more single-family homes, generally may not purchase additional existing single-family homes. Violations carry a penalty of up to $1 million per violation or three times the purchase price, whichever is greater. The restriction does not apply to newly constructed homes or build-to-rent developments, redirecting some capital toward new housing construction rather than the purchase of existing homes. 
• Manufactured and Modular Housing Reform — Several provisions are intended to expand manufactured and modular housing as another way to increase housing supply. The Housing Supply Expansion Act eliminates the federal requirement that manufactured homes be built on a permanent chassis and moves authority for energy efficiency standards to HUD. The Modular Housing Production Act directs the FHA to identify and reduce financing barriers for modular construction, while the Property Improvement and Manufactured Housing Loan Modernization Act raises FHA loan limits for manufactured housing and allows property improvement loans to finance accessory dwelling units.
• NEPA Streamlining — Certain infill and rehabilitation projects funded through the Rural Housing Service are exempt from full review under the National Environmental Policy Act (NEPA). A separate provision, the Unlocking Housing Supply Through Streamlined and Modernized Reviews Act, excludes certain properties from environmental review, especially in the case of office-to-residential conversions.
• Innovation Fund — The law creates a $200 million annual competitive grant program rewarding local governments and tribes that demonstrate measurable increases in housing supply. Unlike most federal housing grants, which are allocated based on need, this program rewards results by encouraging reforms such as streamlined permitting, density bonuses, zoning changes, and infrastructure improvements that support new housing.
• Community Development Block Grant (CDBG) Modernization — The law now allows CDBG funds to be used for new construction rather than only rehabilitation. Communities can now direct up to 20% of their CDBG allocation toward building new affordable housing, which the program didn’t allow at all previously.
• Build Now Act — A companion pilot program ties CDBG allocations to housing growth by providing bonus funding to counties that exceed the median housing growth rate among eligible CDBG recipients.
• HOME Investment Partnerships Program Modernization — The law reauthorizes the HOME program and gives participating jurisdictions new flexibility to use HOME funds for infrastructure, such as water, sewer, and road improvements tied to housing development. This greatly expands what the grant can cover beyond direct construction and rehabilitation costs.
• Small-Dollar Mortgage Expansion — The law reduces barriers to small-dollar mortgages, defined as loans of $100,000 or less, a market many lenders have largely exited.
• Bank Investment Cap Increase — Certain banks may now invest up to 20% of capital in public welfare projects, up from 15%, under the Community Investment and Prosperity Act.

Business Implications

Although many provisions will require additional agency guidance, policy analysts expect several potential business impacts. 

Developers may benefit from shorter project timelines such as environmental reviews, permitting processes, and redevelopment initiatives become more efficient. Construction firms could see increased residential activity over time if communities successfully use the new incentives and expanded federal programs to move more projects into the development pipeline.

The legislation may also influence investment strategies. Large institutional investors subject to the 350-home threshold may move capital toward new construction and build-to-rent neighborhoods.

Finally, local implementation will play an outsized role in determining where new opportunities become available. Businesses involved in housing development should monitor how states and local governments adapt to the new programs and funding opportunities.
