The U.S. Senate has taken a major step toward passing one of the most sweeping housing reform packages in decades. In an overwhelming 84–6 bipartisan vote, Senators advanced the 21st Century ROAD to Housing Act, a blended bill incorporating provisions from both the Senate’s original ROAD to Housing Act and the House‑passed Housing for the 21st Century Act.
For California, where housing affordability remains one of the most pressing economic and humanitarian challenges, this legislation includes several long‑sought reforms that could meaningfully expand production, speed up development, and strengthen housing programs serving low‑income families. So, if passed, what does it do and how will it impact affordable housing in California?
Lifts the Public Welfare Investment Cap from 15% to 20%
One of the most important wins in the bill is the increase in the Public Welfare Investment (PWI) cap. This change will allow financial institutions to increase investments in affordable housing and community development from 15% to 20%. For California, where financing gaps remain one of the biggest barriers to getting projects built, this expanded investment capacity could directly benefit developers, lenders, and communities.
Lifts the Cap on Rental Assistance Demonstration (RAD)
The bill also lifts the cap on RAD, which has been a crucial tool for preserving and rehabilitating older public housing stock. California has one of the largest backlogs of aging public housing in the nation. Expanding RAD will allow more projects to convert to stable, long‑term Section 8 contracts—bringing in private capital while retaining public ownership and affordability protections.
Streamlines NEPA Requirements for Housing Projects
The legislation streamlines National Environmental Policy Act (NEPA) reviews for infill and small‑scale housing developments. In California, environmental review timelines remain among the longest in the U.S. Even when the state streamlines CEQA, federal NEPA reviews can add months or years to project timelines. The new federal streamlining provisions will help by accelerating affordable housing construction, reducing costly delays, and enabling projects near transit, schools, and job centers to move forward faster.
Changes CDBG to Encourage Housing Production
The bill includes updates to the Community Development Block Grant (CDBG) program to better encourage housing development. CDBG remains one of California cities’ most flexible funding sources. These improvements could help jurisdictions improve permitting, infrastructure, and site readiness—directly supporting housing expansion at the local level.
Permanently Authorizes CDBG‑DR
California is hit repeatedly by wildfires, earthquakes, and floods. Permanently authorizing CDBG‑Disaster Recovery (CDBG‑DR), a long‑sought reform, will ensure more predictable and timely support for rebuilding damaged affordable housing.
Reforms the HOME Program
The bill includes several modifications to the HOME Investment Partnerships Program, including exempting small developments from Section 3 requirements. HOME funds are essential to affordable housing development in California, and reducing administrative burdens, especially for small projects, will help local governments stretch these dollars further.
Supports Modular & Manufactured Housing
The bill modernizes standards around modular and manufactured housing to make production easier and more cost‑efficient. Given California’s embrace of modular construction as a path to faster and cheaper development, this reform is likely to support innovation and scale.
Restricts Institutional Investors
At President Trump’s urging, the package includes a new section limiting large private equity firms from purchasing many single‑family homes. While this provision does not directly finance affordable housing, it addresses a growing concern among California communities: the loss of entry‑level homes to corporate buyers. It may help stabilize neighborhoods and reduce competition between families and large investors.
Here’s the bottom line: the 21st Century ROAD to Housing Act represents one of the most significant bipartisan housing efforts in a generation. For California, its impact could include
- more financing for affordable housing,
- faster project approvals,
- expanded preservation tools,
- streamlined federal requirements, and
- stronger support for disaster‑impacted communities.
It moves the nation closer to a federal housing framework that meets the scale of California’s affordability crisis, and that’s a good thing.
