Fifty Years of Historic Preservation in New York City
This white paper offers a detailed overview of the process of designation and the spread of historic districts and landmarks throughout New York City. In addition, it provides additional analyses comparing the land uses, building types, commercial uses, and population in historic districts with those attributes of nearby neighborhoods and lots. A summary of the white paper's findings is available in the accompanying policy brief of the same name.

Flexibility and Conversions in New York City’s Housing Stock: Building for an Era of Rapid Change
The COVID-19 pandemic is just the latest crisis to bring rapid, lasting transformation to American cities. In places like New York City, demand for office spaces and hotels may never return to pre-pandemic levels, while the retail sector continues to decline with the rise of e-commerce. Given these shifting market conditions, conversions of commercial space into
apartments may be a critical tool for adaptation. -
How do New York City’s Recent Rezonings Align With its Goals for Park Accessibility?
In 2007, New York City adopted a long-term sustainability plan that announced a goal of ensuring that almost every New Yorker lives within a ten minute walk of a park of substantial size. At the same time, policymakers are rewriting the City’s land use map through an unprecedented series of neighborhood level rezonings that involve changing the use type and residential capacity of affected lots or groups of lots. Despite the confluence of these interventions, no research has analyzed how the rezonings interact with the City’s park infrastructure, and specifically, whether residential capacity changes in areas close to parks differ from those in areas further away. In this research, we employ a database of every tax lot in New York City to investigate how well the City-initiated rezonings correlate with the goal of providing New Yorkers with good access to the City’s parks. Our results indicate a mixed picture; while most ‘upzoned’ lots (lots where residential capacity was added) were near parks, we also find that the majority of ‘downzoned’ lots (lots where residential capacity was reduced) were also close to parks. The net impact of these rezonings was a modest increase in residential capacity for the City as a whole, but the increases were disproportionately focused in areas further from parks.

How Have Recent Rezonings Affected the City’s Ability to Grow?
How Have Recent Rezonings Affected the City’s Ability to Grow? is the first comprehensive statistical analysis of the City’s rezoning strategy. The report examines the net impact of the 76 rezonings initiated by the City between 2003 and 2007. It finds that, of the 188,000 rezoned lots citywide, 86% were rezoned to reduce or limit new development through either a downzoning or a contextual-only rezoning. Nevertheless, the 14% of lots that were upzoned resulted in a net gain of 100 million square feet of new capacity citywide. The report explores the likelihood that this new capacity will be developed for residential use, and examines the characteristics of neighborhoods that gained new capacity and of those that lost capacity.

Matching Words and Deeds? How Transit-Oriented are the Bloomberg-era Rezonings in New York City?
Anticipating that New York City will grow to more than nine million residents by 2030, the City has launched an ambitious planning agenda focused on development in neighborhoods well served by public transit. Between 2002 and 2009, New York City’s government enacted 100 significant changes to its zoning code, constituting the most significant change to the City’s land use regulations since the original version of the current zoning code was adopted in 1961. This chapter explores the cumulative impact of the individual zoning actions on residential capacity, and how the rezonings match the City’s stated development, environmental and transportation goals. The authors found that, consistent with desired development patterns, there has been a modest overall increase in residential capacity concentrated in neighborhoods near rail transit stations.

Models and Questions to Reform Exclusionary Zoning in New York
Most of New York’s peer states have stepped in to promote inclusive housing development. Their experiences can inform the choices of New York policymakers as they seek to solve New York’s housing crisis.

No Renters in My Suburban Backyard: Land Use Regulation and Rental Housing
Academics and policymakers have argued that the ability of low- and moderate-income families to move into desirable suburban areas is constrained by the high cost of housing. Local zoning and other forms of land use regulation are believed to contribute to increased housing prices by reducing supply and increasing the size of new housing. Suburban restrictions on rental housing are particularly likely to reduce mobility for low-income families. In this paper, I employ an instrumental variables approach to examine the effects of zoning on the quantity and price of rental housing in Massachusetts, using historical municipal characteristics to instrument for current regulations. Results suggest that communities with more restrictive zoning issue significantly fewer building permits for multifamily housing but provide only weak evidence of the effects of regulations on rents. The lack of effects on rents may reflect the low level of multifamily development, while analysis is complicated by development of subsidized housing under the state’s affordable housing law.

Planning for Opportunity: How Planners Can Expand Access to Affordable Opportunity Bargain Areas
There is strong evidence that living in high-opportunity neighborhoods can improve children's long-term educational and economic outcomes; translating this into practical advice for planners is difficult. Planning discussions rarely consider how much that opportunity costs, even though planners must grapple with the typically higher cost of providing housing in opportunity areas. This paper argues for a streamlined measure called the school–violence–poverty (SVP) index based on three contemporary metrics that research shows enhance economic mobility for children: school quality, violent crime, and poverty.

Policy Brief: 21st Century SROs: Can Small Housing Units Help Meet the Need for Affordable Housing in New York City?
This brief explores the potential demand for smaller, cheaper units to help address New York City’s affordable housing need. It considers the feasibility of self-contained micro units as well as efficiency units with shared kitchens and/or baths. The report considers the economics of building and operating small units and models their financial feasibility. It concludes by analyzing the main barriers to the creation of small units that exist in New York City and suggesting possible reforms that New York City can make to address these barriers.
