Why It Matters
A new federal law enacted this month aims to break through local zoning barriers and construction delays by offering communities financial rewards for expanding housing supply and penalties for failing to meet production targets. The approach represents a shift in how Washington deploys federal housing dollars, conditioning grants on measurable results rather than simply distributing funds to established programs.
What Happened
The 21st Century ROAD to Housing Act, a 139-page law passed by Congress, introduces a dual-incentive system designed to accelerate residential construction across the country. The legislation restricts certain institutional investors from purchasing single-family homes, eases regulations on manufactured housing, and expands support for military veterans seeking to buy property.
The law’s centerpiece is a restructuring of how federal housing grants reach local governments. It now allows communities to use a portion of federal block-grant funding for new affordable housing construction—a use previously prohibited. Simultaneously, the measure creates financial consequences for jurisdictions that do not increase their housing stock, reducing federal dollars to cities and counties that fail to meet construction benchmarks.
The law gives local governments broader flexibility in how they deploy federal grants and introduces new mechanisms to remove regulatory obstacles to building. Cities and urban counties can now reduce parking requirements, revise minimum lot sizes and building height restrictions, streamline environmental reviews, create incentives for dense development, alter zoning rules, and eliminate restrictions on accessory dwelling units—all changes designed to lower the cost and timeline of housing projects.
By the Numbers
- 139 — pages in the new federal housing law
- $200 million — annual competitive grants available through the Innovation Fund for communities that increase housing supply
- 2027–2031 — fiscal years covered by the Innovation Fund
- 20% — maximum share of block-grant funding a community can allocate to affordable housing construction
- $3.3 billion — total federal Community Development Block Grant funding appropriated for fiscal year 2026
Structural Changes to Federal Housing Support
The legislation modifies the Community Development Block Grant (CDBG) program, which has distributed federal aid to cities and counties for decades. Under the old framework, CDBG funds could support planning, infrastructure, and other activities but not direct construction of housing units. The new law removes that barrier for affordable housing projects, though with a cap: no more than 20 percent of a recipient community’s total CDBG allocation can be used for construction.
The “Build Now” provision applies to cities and urban counties that receive direct CDBG entitlement funding. Smaller jurisdictions—cities under 50,000 residents and counties with fewer than 200,000 residents—fall into the non-entitlement category and have different funding pathways, though the overall incentive structure applies across the board.
Officials backing the legislation argue the carrot-and-stick approach will unlock housing development where regulatory complexity has stalled it. “The federal government is going to give you a whole lot of carrots, a whole lot of support, and just a couple sticks, in order to encourage these communities to start building more housing,” said Ben Harrold of the National Apartment Association. Mark Kudlowitz of the Local Initiatives Support Corporation added that streamlining grant deployment “is doing everyone a favor” by removing administrative friction.
Zoom Out
Housing affordability and supply shortages have become persistent challenges across the United States, with many regions facing chronic undersupply relative to demand. Federal policymakers have increasingly focused on removing regulatory barriers at the local level—recognizing that zoning, environmental review timelines, and parking mandates often inflate construction costs and extend project timelines. The new law reflects this strategy by tying federal dollars to measurable housing production rather than treating grants as baseline revenue unconnected to outcomes.
The Innovation Fund’s $200 million annual competitive-grant structure borrows from successful models in other federal programs, creating a race among communities to demonstrate housing gains in exchange for additional funding. Hartford, Connecticut Mayor Arunan Arulampalam has praised the competitive grant program as a tool to incentivize faster housing development.
What’s Next
Implementation will begin in fiscal 2027, with communities receiving guidance on eligibility and measurement standards for the Innovation Fund. Local governments will need to assess their zoning codes, parking rules, and development timelines to identify where federal support can accelerate approvals. The CDBG program reductions for underperforming communities will likely spur jurisdictions to act, as federal dollars represent a meaningful revenue source for housing and community development initiatives.
