Regulations Keep Millions of Bedrooms Empty During a Housing Crisis

The U.S. is facing a housing affordability crisis, and new data from Realtor.com highlight an often missed contributing factor: millions of empty bedrooms. Census data reveal 31.8 million “excess” bedrooms in American homes—compared to just 4 million in 1970. Overregulation, particularly in zoning and local occupancy laws, is among the culprits. Realtor.com tries to put a positive…

What’s behind the unprecedented rise in homelessness, and how can we reverse it?

The annual United States homeless population estimates for 2024 were released last week. Homelessness grew by a record 18% annually in 2024, following a then record 12% increase in 2023.

Why Rent Regulation Remains So Hard to Undo in NYC

Few would argue that New York City is mired in a housing crisis — as defined by high prices and low vacancies. There’s good evidence for that conclusion. The most recent federal New York City Housing and Vacancy Survey reported a vacancy rate of just 1.4%, “a stark contrast to the 4.54 rate in 2021”.  Over the same period,…

Why Has Construction Productivity Stagnated? The Role of Land-Use Regulation

Abstract We document a Kuznets curve for construction productivity in 20th-century America. Homes built per construction worker remained stagnant between 1900 and 1940, boomed after World War II, and then plummeted after 1970. The productivity boom from 1940 to 1970 shows that nothing makes technological progress inherently impossible in construction. What stopped it? We present…

Low-Rise Multifamily and Housing Supply: A Case Study of Seattle

Abstract We provide an in-depth case study of land use reforms in Seattle to highlight how redevelopment of aging single-family housing to townhomes can lead to a significant increase in market-rate housing that promotes affordability. The key is to allow market forces to use by-right zoning to drive small-scale development, when also supported by clear…

Affordable Housing—and No Tax Hike

On Nov. 5, Denver’s voters rejected Affordable Denver, a half-cent sales tax increase for subsidized housing. The tax hike would have burdened working families while failing to address the root causes of unaffordable housing. But the vote’s outcome opens the door for a better solution — not only in Denver but also in other Colorado…

NYC Safe Injection Sites Reduce OD Deaths—but Not in the Worst Neighborhoods

There is a glimmer—the slightest bright spot—of good news about drug overdoses in New York. The city’s Health Department reports that overdose deaths in 2023 declined compared to the previous year—but they fell just one percent, from 3,070 to 3,046.  A close look at that number reveals not only is it tiny, but that an important indicator…

Never Let a Crisis End

New York City’s perennial housing crisis—the city has regularly declared a housing “emergency” since 1971—is back on the city council’s agenda, with two proposals to address it. On the surface, the two plans, one championed by Mayor Eric Adams, the other by City Council Speaker Adrienne Adams, seem complementary; both promise more housing. But a…

Lefty NYC Council Add-Ons to Mayor’s ‘City of Yes’ Would Worse Housing Crisis

Eric Adams’ chance for a lasting legacy hinges on his ambitious zoning and housing proposal dubbed “City of Yes” — poised to come before the City Council next week.  But as some community groups seek to derail the plan, the hard-left council looks ready to undermine it — and convert it to the “City of Yes, But.” The key to Adams’…
