Do people drive less because they live in buildings that don’t provide parking, or do they live in buildings that don’t provide parking because they drive less? That question has huge implications for how we build and rebuild our cities, yet researchers have struggled for decades to answer it conclusively. UCLA professor Adam Millard-Ball joins us to discuss new research that finally — we hope — puts the question to bed. Taking advantage of San Francisco’s affordable housing lottery, Millard-Ball and colleagues find that (as-good-as-)randomly assigning tenants to different buildings and neighborhoods has substantial impacts on their transportation choices, with lower parking ratios resulting in less driving and more transit use. We talk about what this means for housing and parking policy, and what it says about the behavioral shifts needed to make cities more affordable, accessible, and sustainable.Show notes:Millard-Ball, A., West, J., Rezaei, N., & Desai, G.

“We have the resources, as a society, to prevent and end homelessness. And the knowledge,” according to Beth Shinn, professor at Vanderbilt University and co-author of In the Midst of Plenty: Homelessness and What To Do About It. So what would that look like? In this conversation, we discuss the Family Options Study, a randomized-controlled trial that evaluated different strategies for addressing family homelessness. The study compared long-term housing subsidies — primarily housing vouchers, which help households pay their rent — with rapid rehousing, transitional housing, and “usual care,” finding that vouchers led to much better outcomes at similar cost to the other options. We also get into what this research can tell us about reducing homelessness for other populations, such as veterans and people with severe mental illnesses. This is our first episode on homelessness in the U.S., and there will be more to come!Show notes:Gubits, D., Shinn, M., Wood, M., Bell, S., Dastrup, S., Solari, C., Brown, S., McInnis, D., McCall, T., & Kattel, U.

Social housing — homes reserved for lower- and middle-income households — has recently become something of a cause célèbre among left-leaning North American housing advocates. Given that, where better to look for guidance than in France? The SRU Law (Loi Solidarité et Renouvellement Urbain, or Solidarity and Urban Renewal) was adopted 20 years ago, requiring many French municipalities to increase their social housing stock to 20%, and later 25%, of all housing. The law has been successful, especially in Paris, but many urban areas continue to hold out, preferring to pay a fee to the national government rather than meet their social housing targets. We’re joined by Professor Magda Maaoui of the University of Cergy-Paris to discuss the law, the “outlaw municipalities” who flout it, and France’s inspiring progress in increasing housing production and reducing housing segregation and the concentration of poverty.Show notes:Maaoui, M.

The international tour continues! This week we interviewed Hayden Shelby, Assistant Professor at the University of Cincinnati, about her research into the Baan Mankong (“Secure Housing”) program in Bangkok, Thailand. Built on the principles of community organizing, finance, and ownership, Baan Mankong has been celebrated as a global model of participatory slum/settlement upgrading for developing countries. But for all its successes, the program is not without its drawbacks, raising difficult questions about the balance between empowerment of poor residents on one hand, and the shirking of state responsibilities on the other. The lessons being learned in Thailand also have implications for community land trusts, tenant opportunity to purchase, and related programs in the U.S. and beyond.Show notes:Shelby, H. (2021).

Vacant houses are often pointed to as a symptom (or cause) of the housing crisis, but what do we really know about them? Where are they located; who lives in them; how many are there? In this conversation we explore foundational, data-driven research on the nature of vacancies in cities and neighborhoods across the U.S. with Professor Jake Wegmann of the University of Texas at Austin. We focus on “ghost dwellings” — houses that are vacant most of the year and primarily seasonal or recreational in use — and discuss their surprising distribution around the country and within cities, what may be driving their proliferation, and how policymakers and advocates should respond to them.Show notes:Wegmann, J.

Every year, more than two million low-income households receive rental assistance through the Housing Choice Voucher program, a federal program that helps renters afford housing on the private market. Currently, only about one-quarter of those eligible for vouchers receive them due to lack of program funding, though Democrats and the Biden administration have proposed expanding it. For our first episode of 2022, Rob Collinson of the University of Notre Dame joins us to talk about how we can get more bang for our buck from housing vouchers, the benefits and drawbacks of the program’s design, and how his research has already helped shape voucher policy reforms in metro areas across the U.S.Show notes:Collinson, R., & Ganong, P.

For this episode, we take a trip to Tokyo to learn from the successes and shortcomings of Japanese housing policy. Known for high rates of production — Tokyo builds five times more housing than California, per capita — and relatively affordable housing, Japan also struggles with poor maintenance and rapid degradation of its buildings. Professor Jiro Yoshida of Pennsylvania State University and the University of Tokyo joins us to talk about the unique demographic, economic, and geographic conditions that led to Japan’s current housing context, and the underrecognized influence of depreciation and tax policy in the choices we make about where and how to live.Show notes:Yoshida, J.

In the 1930s, in the midst of the Great Depression, the Home Owners Loan Corporation (HOLC) was created to protect households from foreclosure and in some cases repurchase homes they’d already lost. As a part of its efforts, HOLC created “residential security maps” to categorize neighborhoods by lending risk, with low-risk neighborhoods shaded in green and blue, and high-risk neighborhoods colored in yellow and red. These infamous maps are where we get the familiar term, “redlining,” and they helped institutionalize America’s racialized housing market. Jacob Faber, Associate Professor at New York University's Robert F. Wagner School of Public Service, joins us to discuss his fascinating new research into HOLC’s influence on racial segregation in the cities where it operated, and the persistence of its effects nearly 100 years after the agency was created.Show notes:Faber, J.

In most of the U.S., cities are for singles, roommates, and childless couples, and the suburbs are for raising kids. That’s not true of much of the rest of the world, and perhaps the nearest example of family-friendly urbanism can be found just a few miles to the north, in Vancouver, British Columbia. Vancouver’s under-15 population fell by one percent citywide between 1996 and 2016, but in downtown specifically, its youth population nearly tripled. Louis Thomas, lecturer at Georgetown University and a parent himself, joins us this week to discuss the history, policies, and social infrastructure that have enabled this incredible shift, and how those lessons might translate to other cities and urban cores across North America.Show notes:Thomas, L.

Cities across the country have dropped the ball when it comes to planning for and building housing at all income levels — especially housing affordable to low-income residents. In response, many states have intervened. The form these interventions take varies from place to place, however, with Northeastern states relying on legal appeals by developers to deliver low-income homes, and Western states mandating local planning processes to achieve similar ends. How is that going? Professor Nicholas Marantz and Dr. Huixin Zheng join us this week to discuss the strengths and weaknesses of these different approaches, and reforms that could make them work better.Show notes:Marantz, N.
