New Housing and Displacement

The Institute of Governmental Studies at UC Berkeley has issued a research brief, Housing Production, Filtering and Displacement: Untangling the Relationships. It opens,

Debate over the relative importance of subsidized and market-rate housing production in alleviating the current housing crisis continues to preoccupy policymakers, developers, and advocates. This research brief adds to the discussion by providing a nuanced analysis of the relationship between housing production, affordability, and displacement in the San Francisco Bay Area, finding that:

• At the regional level, both market-rate and subsidized housing reduce displacement pressures, but subsidized housing has over double the impact of market-rate units.

• Market-rate production is associated with higher housing cost burden for low-income households, but lower median rents in subsequent decades.

• At the local, block group level in San Francisco, neither market-rate nor subsidized housing production has the protective power they do at the regional scale, likely due to the extreme mismatch between demand and supply.

Although more detailed analysis is needed to clarify the complex relationship between development, affordability, and displacement at the local scale, this research implies the importance of not only increasing production of subsidized and market-rate housing in California’s coastal communities, but also investing in the preservation of housing affordability and stabilizing vulnerable communities. (1)

This brief takes on an important subject — the relationship between new housing and displacement — and concludes,

There is no denying the desperate need for housing in California’s coastal communities and similar housing markets around the U.S. Yet, while places like the Bay Area are suffering from ballooning housing prices that are affecting people at all income levels, the development of market-rate housing may not be the most effective tool to prevent the displacement of low-income residents from their neighborhoods, nor to increase affordability at the neighborhood scale.

Through our analysis, we found that both market-rate and subsidized housing development can reduce displacement pressures, but subsidized housing is twice as effective as market-rate development at the regional level. It is unclear, however, if subsidized housing production can have a protective effect on the neighborhood even for those not fortunate enough to live in the subsidized units themselves.

By looking at data from the region and drilling down to local case studies, we also see that the housing market dynamics and their impact on displacement operate differently at these different scales. Further research and more detailed data would be needed to better understand the mechanisms via which housing production affects neighborhood affordability and displacement pressures. We know that other neighborhood amenities such as parks, schools, and transit have a significant impact on housing demand and neighborhood change and it will take additional research to better untangle the various processes at the local level.

In overheated markets like San Francisco, addressing the displacement crisis will require aggressive preservation strategies in addition to the development of subsidized and market-rate housing, as building alone won’t protect specific vulnerable neighborhoods and households. This does not mean that we should not continue and even accelerate building. However, to help stabilize existing communities we need to look beyond housing development alone to strategies that protect tenants and help them stay in their homes. (10-11, footnote omitted)

The brief struggles with a paradox of housing — how come rents keep going up in neighborhoods with lots of new construction? The answer appears to be that the broad regional demand for housing in a market like the Bay Area or New York City overwhelms the local increase in housing supply. The new housing, then, just acts like a signal of gentrification in the neighborhoods in which it is located.

If I were to criticize this brief, I would say that it muddies the waters a bit as to what we need in hot markets like SF and NYC: first and foremost, far more housing units. In the absence of a major increase in supply, there will be intense market pressure to increase rents or convert units to condominiums. Local governments will have a really hard time overcoming that pressure and may just watch as area median income rises along with rents. New housing may not resolve the problem of large-scale displacement, but it will be hard to address displacement without it. Preservation policies should be pursued as well, but the only long-term solution is a lot more housing.

I would also say that the brief elides over the cost of building subsidized housing when it argues that subsidized housing has twice the impact of market-rate units on displacement. The question remains — at what cost? Subsidized housing is extremely expensive, often costing six figures per unit for new housing construction. The brief does not tackle the question of how many government dollars are needed to stop the displacement of one low-income household.

My bottom line: this brief begins to untangle the relationship between housing production and displacement, but there is more work to be done on this topic.

Gentrification and Displacement

Miriam Zuk et al. have posted a Federal Reserve Bank of San Francisco Working Paper, Gentrification, Displacement and The Role of Public Investment: A Literature Review. The paper opens,

The United States’ metropolitan areas’ ever-changing economies, demographics, and morphologies have fostered opportunity for some and hardship for others. These differential experiences “land” in place, and specifically in neighborhoods. Generally, three dynamic processes can be identified as important determinants of neighborhood change: movement of people, public policies and investments, and flows of private capital. These influences are by no means mutually exclusive – in fact they are very much mutually dependent – and they each are mediated by conceptions of race, class, place, and scale. How scholars approach the study of neighborhood change and the relative emphasis that they place on these three influences shapes the questions asked and attendant interventions proposed.

These catalysts result in a range of transformations – physical, demographic, political, economic – along upward, downward, or flat trajectories. In urban studies and policy, scholars have devoted volumes to analyzing neighborhood decline and subsequent revitalization at the hands of government, market, and individual interventions. One particular category of neighborhood change is gentrification, definitions and impacts of which have been debated for at least fifty years. Central to these debates is confronting and documenting the differential impacts on incumbent and new residents, and questions of who bears the burden and who reaps the benefits of changes. Few studies have addressed the role of public investment, and more specifically transit investment, in gentrification. Moreover, little has been written about how transit investment may spur neighborhood disinvestment and decline. Yet, at a time when so many U.S. regions are considering how best to accommodate future growth via public investment, developing a better understanding of its relationship with neighborhood change is critical to crafting more effective public policy.

This literature review will document the vast bodies of scholarship that have sought to examine these issues. First, we contextualize the concept and study of neighborhood change. Second, we delve into the literature on neighborhood decline and ascent (gentrification). The third section examines the role of public investment, specifically transit investment, on neighborhood change. Next, we examine the range of studies that have tried to define and measure one of gentrification’s most pronounced negative impacts: displacement. After describing the evolution of urban simulation models and their ability to incorporate racial and income transition, we conclude with an examination of gentrification and displacement assessment tools. (2, footnote omitted)

Because gentrification is such a contested topic both within and without the academy, this literature review is very useful. Notwithstanding the fact that the results of many of the studies mentioned are mixed, the authors were able to identify certain findings that emerge from the literature. These include,

  • Neighborhoods change slowly, but over time are becoming more segregated by income, due in part to macro-level increases in income inequality.
  • Racial segregation harms life chances and persists due to patterns of in-migration, “tipping points,” and other processes; however, racial integration is increasing, particularly in growing cities.
  • Despite severe data and analytic challenges in measuring the extent of displacement, most studies agree that gentrification at a minimum leads to exclusionary displacement and may push out some renters as well. (44-45)

As hot cities like New York and San Francisco struggle with their changing housing markets, policy makers should make decisions based on the best available research on gentrification and displacement. This literature review provides a guide.
