Silver Bullet or Trojan Horse? The Effects of Inclusionary Zoning on Local Housing Markets in the United States
Many local governments are adopting inclusionary zoning (IZ) as a means of producing affordable housing without direct public subsidies. In this paper, we use panel data on IZ in the San Francisco metropolitan area and Suburban Boston to analyze how much affordable housing the programs produce and how IZ affects the prices and production of market-rate housing. The amount of affordable housing produced under IZ has been modest and depends primarily on how long IZ has been in place. Results from Suburban Boston suggest that IZ has contributed to increased housing prices and lower rates of production during periods of regional house price appreciation. In the San Francisco area, IZ also appears to increase housing prices in times of regional price appreciation but depresses prices during cooler regional markets. There is no evidence of a statistically significant effect of IZ on new housing development in the Bay Area.

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.

Policy Brief
The Effects of Inclusionary Zoning on Local Housing Markets
This study evaluates the impact of Inclusionary Zoning policies on housing markets in the San Francisco, Washington D.C. and suburban Boston areas. The analysis provides local decision-makers with valuable evidence on the impacts of IZ—a popular but often-controversial affordable housing policy. The policy brief includes an update from February 2010, summarizing additional research that has been completed since the original publication in March, 2008.

Working Paper
The Effects of Inclusionary Zoning on Local Housing Markets
Many local governments in metropolitan areas with high housing costs are adopting inclusionary zoning (IZ) as a means of producing housing that is affordable to low- and moderate-income households without direct public subsidies. Critics charge that IZ ordinances impose additional costs on new development and may lead to reductions in supply and increases in the price of market rate housing. Advocates of IZ argue that any negative effects IZ might have on production can be mitigated through density bonuses or other cost offsets. Rigorous empirical study of the effects of inclusionary zoning ordinances has been hampered by the lack of accurate, timely data describing IZ and the land use regulatory schemes in which IZ programs fit. In this paper, we use panel data on the adoption and characteristics of IZ in the San Francisco and Washington DC metropolitan areas and the Boston-area suburbs to analyze which jurisdictions adopt IZ, how much affordable housing the programs produce and the effects of IZ on the prices and production of market-rate housing. The IZ programs among our sample jurisdictions are complex policies and exhibit considerable variation in their design, particularly across the three regions. We find that larger, more highly educated jurisdictions and those surrounded by more neighbors with IZ are more likely to adopt IZ. Whether and how many affordable units are produced under IZ depends primarily on the length of time IZ has been in place. The results from Boston-area suburbs provide some evidence that IZ has contributed to increased housing prices and lower rates of housing production. There is no evidence that IZ has constrained supply or increased prices among Bay Area jurisdictions. Limitations on the availability and quality of our data suggest that our results should be interpreted cautiously, but also suggest that IZ programs should be designed cautiously to mitigate possible negative impacts on housing supply.
