In many ways, U.S. housing policy is entering unchartered waters: the current housing market must adjust to particularly high rent burdens and affordability challenges that affect nearly every American. With that in mind, Professor John Landis and I, with support of Penn IUR, Housing Policy Debate, and the Fels Policy Institute at Penn, convened a symposium on September 15th that brought together some of the most forward-thinking scholars from across the country to discuss the future of housing policy in the United States.
In “Ten for Ten: 10 New Realities Policymakers Should Keep in Mind as They Think About the Next 10 Years of Federal Housing Policy,” a framing paper for the event, Professor Landis and I highlight the challenges, and opportunities facing U.S. housing policy. For example, we find that nearly half of the 44 million households renting in 2015 were rent burdened, meaning they spend over 30 percent of their income in rent. This is particularly true for the lowest income households –with 89 percent of households with incomes below $20,000 being rent burdened. In 2015, federal tax expenditures that went toward supporting affordable rental housing were approximately 21 percent of what was spent on homeownership, which represents a roughly 3 percentage-point decrease from 2000, despite the fact that there are three times more rent-burdened low-income households than there are subsidized rental units in the country. At the same time, re-investment in cities is leading to increased gentrification in counties as large as Los Angeles County, California, and as small as Pulaski County, Arkansas.
Further, since 2010, the national rate of new home construction has fallen behind job and household growth rate, leading to higher demand for fewer units. Housing markets in the Northeast and West Coast in particular have witnessed rapid price appreciation, raising concerns about the attainability of homeownership for most renters in these markets. One response to affordability concerns is to increase the supply of housing. However, we show that overly-stringent land use regulations make it difficult to increase the supply of housing units in many places, which is driving up both rents and property values.
While these challenges exist, the symposium highlighted a large body of empirical evidence that demonstrates what does work.
At the Symposium, housing experts offered their views on these findings, their policy suggestions, and their perspectives on the changing environment for housing policy. Columbia University Professor Lance Freeman reflected on the need to balance investment in neighborhoods with concerns about potential displacement; UC Berkeley Professor Carol Galante and Urban Institute’s Margery Turner emphasized the need to think creatively about development challenges and opportunities and make the case for bold approaches to housing policy, respectively. Finally, Ford Foundation Vice President Xavier De Souza Briggs voiced his position on the need to develop coalitions that provide a base for meaningful housing policy and change.
The conference proceedings will be featured in a forthcoming special issue of Housing Policy Debate.
