31 Flavors of Inclusionary Zoning: Comparing Policies From San Francisco, Washington, DC, and Suburban Boston
As housing costs have risen in the U.S. and federal subsidies for affordable housing programs have declined, inclusionary zoning (IZ) has become an increasingly popular local policy for producing low-income housing without direct public subsidy. The structure of IZ policies can vary in a number of ways; consequently, there is not yet a consensus about what policies constitute “true” inclusionary zoning. In this paper we compare the ways in which IZ programs have been structured in three regions in which it is relatively widespread and long-standing. Our results demonstrate that IZ programs are highly complex and exhibit considerable variation in their structures and outcomes. In the San Francisco Bay Area, IZ programs tend to be mandatory and apply broadly across locations and structure types, but attempt to soften potential negative impacts with cost offsets and alternatives to on-site construction. In the Washington DC area, most IZ programs are also mandatory, but have broader exemptions for small developments and low-density housing types. IZ programs in the Suburban Boston area exhibit the most withinregion heterogeneity. In this area, IZ is more likely to be voluntary and to apply only to a narrow range of developments, such as multifamily or age-restricted housing, or within certain zoning districts. The amount of affordable housing produced under IZ varies considerably, both within and across the regions. The flexibility of IZ allows planners to create a program that accommodates local policy goals, housing market conditions and political circumstances.

Building Environmentally Sustainable Communities: A Framework for Inclusivity
The U.S. Department of Housing and Urban Development (HUD) has decided to include two key goals in all of its programs: encouraging sustainable communities and enhancing access to opportunity for lower-income people and people of color. This paper examines the relationship between these two goals through a literature review and an original empirical analysis of how these goals interact at the neighborhood and metropolitan area levels. We also offer policy recommendations for HUD.

Buying Sky: The Market for Transferable Development Rights in New York City
This policy brief analyzes development right transfers in New York City between 2003 and 2011, looking at the prices paid, number of rights transferred, location of the sending and receiving parcels, and legal mechanisms used, in order to shed light on an important but hard-to-track market. The report, “Buying Sky: The Market for Transferable Development Rights in New York City,” examines 243 arms-length transactions for which complete data is available, and finds wide variation in the price paid per square foot of development rights, even for sales within the same neighborhoods, programs, and time periods. See the press release or read the full report.

Challenges Facing Housing Markets in the Next Decade: Developing a Policy-Relevant Research Agenda
This paper proposes a research agenda that addresses the major challenges facing the U.S. housing market: the long-term effects of the housing market crisis on today’s households and on the next generation, increasing poverty coupled with persistently high income inequality and volatility, continued concentration of poor and minority households in low-quality housing and low-opportunity neighborhoods, and the growing need for sustainable and resilient buildings and communities. This analysis is a framing paper for the What Works Collaborative, a foundation-supported research partnership that conducts timely research and analysis to help inform the implementation of an evidence-based housing and urban policy agenda.

Comment on ‘The Effects of Affordable and Multifamily Housing on Market Values of Nearby Homes’
Advocates of growth management and smart growth often propose policies that raise housing prices, thereby making housing less affordable to many households trying to buy or rent homes. Such policies include urban growth boundaries, zoning restrictions on multi-family housing, utility district lines, building permit caps, and even construction moratoria. Does this mean there is an inherent conflict between growth management and smart growth on the one hand, and creating more affordable housing on the other? Or can growth management and smart growth promote policies that help increase the supply of affordable housing?

Community Benefits Agreements: A New Local Government Tool or Another Variation on the Exactions Theme?
Community benefits agreements (CBAs) are the latest in a long line of tools neighbors have used to protect their neighborhood from the burdens of development, and to try to secure benefits from the proposed development. This Article canvasses the benefits and drawbacks various stakeholders perceive CBAs to offer or to threaten, and reviews the legal and policy questions CBAs present. It recommends that local governments avoid the use of CBAs in land use approval processes unless the CBAs are negotiated through processes designed to ensure the transparency of the negotiations, the representativeness and accountability of the negotiators, and the legality and enforceability of the CBAs’ terms.

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.

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.

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.
