Congress threatens build-to-rent in housing bill

Source: washingtonpost.com

TL;DR

Senate-passed 21st Century ROAD to Housing Act includes Section 901 restricting large institutional investors from buying single-family homes.
Section 901 prohibits investors controlling 350+ homes from purchases, with exceptions like build-to-rent requiring sales after seven years.[[1]](https://www.banking.senate.gov/imo/media/doc/MIR26311.pdf)[[2]](https://www.washingtonpost.com/opinions/2026/04/06/build-to-rent-housing-congress-single-family-homes/)
Provision could cut new single-family rentals by 72,000 units yearly, undermining bill's supply-boosting goal per Urban Institute analysis.[[3]](https://www.multifamilydive.com/news/housing-researchers-support-build-to-rent/816243)

The story at a glance

Brad Hargreaves argues in this Washington Post opinion that Section 901 of the bipartisan 21st Century ROAD to Housing Act threatens build-to-rent housing, a key source of new single-family homes. The Senate passed the bill recently; it now awaits House action. The provision targets large institutional investors—those with 350 or more single-family homes—despite their small overall market share.[[4]](https://www.washingtonpost.com/opinions/2026/04/06/build-to-rent-housing-congress-single-family-homes)

Key points

Congress rarely passes ambitious bipartisan housing bills; the ROAD to Housing Act aims to cut red tape and boost construction.[[4]](https://www.washingtonpost.com/opinions/2026/04/06/build-to-rent-housing-congress-single-family-homes)
Section 901 ("Homes Are for People, Not Corporations") bars large institutional investors from buying single-family homes, defining them as for-profit entities controlling 350+ such properties.[[1]](https://www.banking.senate.gov/imo/media/doc/MIR26311.pdf)
Exceptions allow build-to-rent purchases of new homes for rental, but investors must sell them within seven years or face penalties.
Build-to-rent is expanding despite offering the lowest returns among institutional real estate classes, adding needed rental supply in suburbs with good schools.[[4]](https://www.washingtonpost.com/opinions/2026/04/06/build-to-rent-housing-congress-single-family-homes)
Critics, including 25 housing researchers and Urban Institute, warn it could reduce single-family completions by over 7% and rentals by 72,000 annually.[[3]](https://www.multifamilydive.com/news/housing-researchers-support-build-to-rent/816243)
Hargreaves says institutional investors own under 1% of U.S. single-family homes but drive new construction when others won't.[[4]](https://www.washingtonpost.com/opinions/2026/04/06/build-to-rent-housing-congress-single-family-homes)

Details and context

Build-to-rent involves developers constructing single-family home communities explicitly for long-term renting, often in growing suburbs. These projects rely on large-scale institutional capital because they offer modest returns and require upfront investment that small landlords rarely provide.[[5]](https://www.washingtonpost.com/ripple/2026/03/16/bipartisan-housing-bill-investors-single-family-homes)

Section 901 permits such purchases as "excepted" but mandates divestiture after seven years, which Hargreaves calls frustrating since it disrupts the rental model without forcing sales of existing holdings. Housing experts note this could chill investment, as the short hold period limits income to recoup costs—potentially preventing homes from being built at all, rather than shifting them to owners.[[3]](https://www.multifamilydive.com/news/housing-researchers-support-build-to-rent/816243)

The bill's other reforms promote supply through zoning incentives and streamlined reviews, making Section 901 a self-defeating addition amid America's housing shortage.

Key quotes

"Build-to-rent is growing as a market sector even though it generates some of the lowest returns of any institutional real estate asset class."[[4]](https://www.washingtonpost.com/opinions/2026/04/06/build-to-rent-housing-congress-single-family-homes) — Brad Hargreaves, Washington Post opinion.

Why it matters

A bipartisan push to ease housing shortages risks backfiring if Section 901 stalls build-to-rent, which adds tens of thousands of new units yearly. Renters in high-opportunity areas could face fewer options and higher costs, while developers lose a reliable funding source for suburban projects. Watch House debates and potential amendments to Section 901, as its fate could shape whether the bill expands or shrinks supply.[[6]](https://www.rer.org/roundtable-weekly/march-27-2026)
