Compact Units: Demand and Challenges
This research brief explores the potential that smaller housing units offer in meeting evolving housing needs and the regulatory barriers that inhibit their construction. The brief and the accompanying white paper, Responding to Changing Households: Regulatory Challenges for Micro-Units and Accessory Dwelling Units, focuses on five U.S. urban areas (New York, Washington D.C., Austin, Denver, and Seattle), and outlines the regulatory, financial, and political barriers that impede the development of smaller, denser housing types, such as micro-units and accessory dwelling units. Read the white paper (PDF) or view the press release.

Creating Affordable Housing Out of Thin Air: The Economics of Mandatory Inclusionary Zoning in New York City
This policy brief examines the economic potential of a mandatory inclusionary zoning policy to produce new affordable units tied to upzonings across New York City’s neighborhoods. It finds that a mandatory inclusionary zoning policy in New York City has the potential to produce affordable units in neighborhoods that already command high rent, such as East Harlem. But the city’s low-rent neighborhoods, such as East New York and Jerome Avenue, may not have sufficient market strength to justify high-density mixed-income development without other forms of subsidy. The study considers the role of 421-a, as well as key policy trade-offs including on-site vs. off-site, depth of affordability, and permanent affordability.

Ending Exclusionary Zoning in New York City’s Suburbs
New York stands alone among its peer states—coastal states with high housing costs and healthy regional economies—in giving its local governments such broad authority over local land use. The result is a state with fewer homes, more expensive rents, and starker segregation than it would otherwise have. By some measures, New York has the most exclusionary zoning in the country. This paper therefore offers a guide for New York State to follow, and improve upon, its peer states and reform its broken suburban land use process.

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. -
Give Credit Where Credit Is Due: Overhauling the CRA
The Community Reinvestment Act (CRA) is in need of a major overhaul. Since the CRA was enacted in 1977, and since the last major rewrite of the regulations more than 15 years ago, much about the financial services industry has changed. This chapter discusses why the regulatory system needs to be redesigned to allow for more regular and timely updates, allowing more rapid responses to what is working and what is not. By being more amenable to continuous improvement, the CRA should be more open to innovation and experimentation given the greater opportunity for making midterm corrections. This chapter starts with a brief overview of the CRA and its successes. It then outlines some ways to facilitate more regular updating of the CRA regulations, followed by a review of a number of ways to increase the effectiveness of CRA in helping to stabilize and revitalize low-and moderate-income (LMI) communities.

How Can Historic Preservation Be More Inclusive? Learning From New York City’s Historic Districts
Historic preservation policies uphold the cultural heritage of a city while also impacting the social and economic landscape of the neighborhoods preserved. This chapter describes findings from analyses that compare New York City neighborhoods which received historic designations with comparable ones that did not. To broaden the agenda of the preservation community, the authors describe effects seen in work done by the New York City Landmarks Preservation Commission ever since it was created in 1965. They advocate for a closer look at the impact historic preservation has on equity, diversity, and inclusion.

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.

Impact Fees and Housing Affordability
The increasing use of impact fees and the costs that they may add to the development process raises serious concerns about the effect using impact fees to fund infrastructure will have on the affordability of housing.
