WASHINGTON — Barely three months after the landmark enactment of the 21st Century ROAD to Housing Act, key housing industry stakeholders, trade groups, and bipartisan lawmakers are already mobilizing. Their mission: to develop a legislative successor—provisionally dubbed "ROAD 2.0"—designed to build upon the momentum, plug the gaps, and expand the horizons of the original federal policy.
Behind the scenes on Capitol Hill, early legislative architecture is beginning to take shape. A comprehensive, 95-page policy document drafted by the 40-member, bipartisan Build America Caucus offers a compelling roadmap for the future. Sweeping in scope, the proposal spans housing, healthcare, energy, innovation, and transportation, but its core focus zeroes in onAmerica’s persistent and systemic housing affordability and inventory crises.
The document, which first came to light via Politico, establishes a federal blueprint centered on three primary pillars: expanding developable land, driving down the regulatory and material costs of construction, and broadening access to capital for residential projects. While many of these proposed reforms would ultimately be implemented at state and local levels, the framework outlines innovative ways the federal government can use fiscal carrots—and financial incentives—to encourage local municipalities to embrace pro-housing zoning and administrative overhauls.
Chronology of the Push: From the 21st Century ROAD Act to the Horizon of ROAD 2.0
The urgency driving the conversation around a potential ROAD 2.0 is rooted in the high-stakes legislative battles that preceded the original law.
- Late 2024 to Early 2025: As housing inflation continued to outpace wage growth across major metropolitan and rural markets alike, housing advocates and real estate trade organizations ramped up lobbying efforts for comprehensive federal intervention, culminating in the drafting of the 21st Century ROAD to Housing Act.
- Mid-2025: Negotiations on Capitol Hill forced lawmakers to make difficult compromises. Several aggressive measures—particularly those targeting local zoning barriers and transit-oriented development—were stripped from the final text of the ROAD Act to secure the necessary bipartisan consensus for passage.
- Late 2025 (Present): Approximately three months after the original bill was signed into law, housing industry leaders have begun huddling up to review its initial impacts. Recognizing that the first iteration was merely a foundational step, policymakers and industry groups are turning their attention to the unfinished business of the housing reform agenda.
- The Present Blueprint: The release of the 95-page Build America Caucus document marks the official unofficial kickoff of the "ROAD 2.0" era. Lawmakers are currently socializing these proposals among industry stakeholders, laying the groundwork for formal bill introductions in the upcoming congressional sessions.
Supporting Data: The Anatomy of the Housing Crisis
To understand why lawmakers are already drafting a sequel to a major housing bill, one must examine the staggering macroeconomic data driving the current housing shortage. The Build America Caucus report highlights several critical economic pain points that continue to choke residential construction:
- Escalating Material Costs: According to the report’s findings, material inputs for residential construction have skyrocketed by a staggering 42% over the last five years. This represents a massive acceleration compared to the prior five-year period, which saw a modest 7% growth in material costs.
- Tightening Credit Conditions: Homebuilders and real estate developers have reported tightening credit conditions for more than four consecutive years. High interest rates and conservative lending environments have choked off capital, particularly for small-to-mid-sized developers.
- Mass Timber Efficiency: Citing modern construction innovations, the report notes that using mass timber for mid-sized multifamily housing can cut construction timelines by approximately 25% compared to traditional concrete and steel, offering a vital pathway to faster project delivery if regulatory bottlenecks are cleared.
- The ADU Untapped Potential: In land-constrained states like California and the Northeast, accessory dwelling units (ADUs) represent one of the most organic ways to scale housing density. However, because conventional financing is largely inaccessible for ADU construction, the vast majority of units are currently built exclusively by cash-rich homeowners, leaving a massive pool of potential housing units locked out of the market.
Opening Up More Sites for Housing Development
The first core section of the policy agenda, titled "Expand where housing can be built," targets the local regulatory and geographic bottlenecks that artificially restrict the supply of land available for residential construction.
Right to Build Zones
Across the United States, municipal zoning boards—often bowing to local pressure from anti-growth or NIMBY (Not In My Back Yard) factions—have preserved outdated, exclusionary zoning policies that make building apartments, townhomes, and missing-middle housing nearly impossible.
To break this gridlock, the agenda proposes the creation of "Right to Build Zones." Under this framework, municipalities would designate specific zones where residential housing would gain automatic, "by-right" approval, provided developers adhere to pre-established, standardized zoning and permitting rules.
Proponents argue this system would slash the bureaucratic delays and legal fees that artificially inflate home prices. To encourage participation, the federal government would step in with financial incentives, offering a fixed financial payment to local governments for every completed home built above the community’s recent baseline construction levels. While exact figures remain under discussion, the blueprint suggests tying these payments to the rough equivalent of municipal impact fees, ensuring local governments can still cover the costs of expanded infrastructure, roads, and schools.
Transit-Oriented Development
Despite millions of federal dollars pouring into public transit infrastructure every year, many American cities chronically underutilize land immediately surrounding train stations, light rail stops, and major bus corridors. These transit-oriented sites are inherently ideal for higher-density housing.
The new agenda proposes directing federal transit grants and low-cost financing opportunities exclusively to communities that proactively adopt pro-housing zoning reforms around major transit hubs. This concept closely mirrors the framework of the Build More Housing Near Transit Act of 2025 (H.R. 4576), which sought to incentivize multifamily development near transit corridors but was ultimately left out of the final text of the original 21st Century ROAD to Housing Act.
Leveraging Federal Property for Housing
The federal government is one of the largest property owners in the country. Agencies such as the General Services Administration (GSA) and the U.S. Postal Service (USPS) sit on millions of square feet of underutilized real estate, parking lots, and surplus office buildings.
A housing-focused federal mandate could compel or incentivize these agencies to unlock surplus real estate for residential conversion and development. Industry analysts estimate this policy alone could help pave the way for hundreds of thousands of new housing units nationwide while generating valuable non-tax revenue for the federal government.
Lowering Material and Regulatory Costs
Beyond the physical availability of land, residential construction is heavily encumbered by rising input costs, regulatory red tape, and fragmented compliance frameworks.
Targeted Tariff Relief and Regulatory Exemptions
Supply chain shocks, persistent inflation, and federal trade policies have combined to push material costs to historic highs. To combat these pressures, the policy agenda recommends exempting affordable housing developments from restrictive "Build America, Buy America" sourcing mandates. Additionally, it calls for targeted tariff relief on essential residential construction materials to provide immediate fiscal breathing room to builders.
Modernizing Fragmented, Prescriptive Building Codes
National model building codes are updated on a three-year cycle, but thousands of local municipalities lack the personnel, financial resources, or technical capacity to evaluate and adopt new editions in a timely manner. This has resulted in a chaotic, fragmented patchwork of building codes across state and county lines, driving up compliance costs and forcing regional builders to navigate wildly inconsistent rules.
Furthermore, overly prescriptive building codes often stifle innovation, making it exceedingly difficult for builders to adopt new, cost-saving, eco-friendly materials and construction methods—even when those alternatives meet or exceed baseline safety standards. The proposed framework suggests that federal technical and financial assistance can help local jurisdictions modernize their codes and transition toward more flexible, performance-based standards.
Overcoming Barriers to Transporting Mass Timber
Mass timber is rapidly emerging as a revolutionary material for mid-sized multifamily developments. Being significantly lighter than concrete and steel, it can accelerate structural construction timelines by roughly a quarter.
However, transporting oversized mass timber components across state and local jurisdictions remains a logistical nightmare due to conflicting, highly fragmented rules regarding oversized loads. The policy agenda proposes using federal grant incentives to encourage states to harmonize and streamline their permitting and transit rules for oversized mass timber deliveries.
Filling Financing Gaps for Housing Construction
Tight credit conditions, conservative underwriting, and high interest rates have created a severe liquidity crunch for residential developers, particularly for projects that fall outside of conventional lending parameters.
Creating a Federal Revolving Loan Fund
To bridge these financing chasms, the agenda proposes establishing a federal revolving loan fund. Many smaller, complex, or unconventional housing projects are currently passed over by traditional commercial lenders, despite being financially sound.
Several forward-thinking states—including Oregon, New York, Kansas, Hawaii, Arizona, and Virginia—have already established successful state-level revolving loan funds. Under these models, loan repayments are recycled to finance successive rounds of construction, stretching public capital further over time. A federal counterpart would scale this mechanism nationwide.
Modernizing FHA Financing for Infill Development
Federal Housing Administration (FHA) construction-to-permanent loans can offer highly advantageous financial terms compared to conventional commercial debt, but they are frequently criticized as being far too slow, rigid, and administratively burdensome for modern urban developers.
To accelerate infill development, the policy blueprint suggests modernizing HUD’s antiquated technological systems and underwriting guidelines. It also recommends implementing broad categorical exclusions for infill housing projects to streamline and expedite cumbersome National Environmental Policy Act (NEPA) environmental reviews.
Expanding Federal Financing Options for Accessory Dwelling Units (ADUs)
Accessory dwelling units are widely recognized as a pragmatic solution to missing-middle housing shortages, allowing homeowners to build detached backyrd cottages, garage conversions, or basement apartments. However, financing remains a primary hurdle. Currently, the vast majority of ADUs are built exclusively by homeowners with substantial liquid cash reserves.
To democratize ADU construction, the agenda proposes introducing federally backed second-mortgage products specifically tailored for ADU development. Crucially, these financial products would be structured to account for the property’s anticipated future rental income and post-construction equity value. Most importantly, the proposal would allow homeowners to secure financing without forfeiting or refinancing their existing, low-rate primary mortgages—a massive incentive in a high-rate economic environment.
Official Responses and Industry Implications
The release of the Build America Caucus document has drawn cautious optimism—and immediate engagement—from across the housing sector.
Trade groups, including the National Association of Home Builders (NAHB) and the Mortgage Bankers Association (MBA), have praised lawmakers for looking beyond the horizon of the initial ROAD Act.
"The 21st Century ROAD to Housing Act was a vital first down, but solving a generational housing deficit requires a sustained, multi-playbook drive," noted one senior housing lobbyist familiar with the caucus discussions. "By focusing directly on zoning reform, tariff relief on materials, and modernizing financing for ADUs and infill sites, ROAD 2.0 addresses the ground-level realities that builders face every single day."
Meanwhile, local government associations have urged caution, emphasizing that any federal incentive programs must respect local autonomy and avoid heavy-handed federal mandates that ignore regional geographic and cultural differences.
As Capitol Hill prepares for future legislative cycles, the conversation surrounding ROAD 2.0 signals a maturing bipartisan consensus: solving America’s housing crisis will require sustained, iterative federal policy action that partners directly with states, cities, and the private market to unlock inventory and drive down costs.
