A major bipartisan housing reform law has officially taken effect in the United States, aiming to increase housing supply, reduce costs and expand access to affordable homes.
A Broad Reform Package Becomes Law
The 21st Century Road to Housing Act became law after President Donald Trump did not sign or veto the legislation within the required timeframe. The measure includes 47 proposals designed to address long-standing pressures in the US housing market, where high mortgage rates and record property prices have made homeownership more difficult for many households.
Supporters describe it as the most wide-ranging housing reform package in decades. The law focuses mainly on increasing the number of available homes rather than directly reducing mortgage costs or monthly rents.
More Housing Construction Is a Main Focus
The legislation seeks to increase housing supply through measures supporting manufactured housing, conversions of unused office buildings into apartments and funding programmes for the repair of older homes.
Housing experts have argued that years of limited construction, restrictive local zoning rules and rising demand have contributed to shortages and higher prices. The law encourages states and local governments to adopt policies that make new housing development easier, although it does not force them to change their rules.
A 2025 Goldman Sachs report estimated that easing land-use restrictions could add around 2.5 million homes across the US over the next decade. The speed of any increase in housing supply will depend on decisions made by local authorities, developers and communities.
Limits Placed on Large Housing Investors
The legislation also introduces restrictions on some large-scale housing investors. Companies or investors owning more than 350 single-family homes will no longer be able to purchase additional properties under the new rules. The measure does not require major investors to sell homes they already own.
Housing analysts note that most investor-owned properties belong to smaller landlords, with many owning fewer than 10 homes. Large institutional investors have also reduced purchases in some parts of the housing market in recent years.
Implementation Could Be a Challenge
The effectiveness of the law will depend heavily on how federal agencies put the measures into practice. Housing specialists have warned that government agencies may face difficulties managing the additional workload due to staffing limitations.
The Urban Institute identified dozens of programmes, regulations and studies that the Department of Housing and Urban Development will need to oversee. Shaun Donovan, former Secretary of Housing and Urban Development, said the law could unlock funding and change regulations, but its results would depend on implementation.
Immediate Relief Is Unlikely
Although the law represents a major policy change, experts say it is unlikely to quickly reduce housing costs. Building new homes, changing local rules and attracting private investment can take years.
For renters and potential buyers facing high costs today, the legislation may not provide immediate relief. Its main objective is to create conditions for a larger housing supply over time and address some of the structural causes behind the affordability crisis.
