Inclusionary Housing: Fact and Fiction

By David Reiss

The Center for Housing Policy has issued a policy brief, Separating Fact from Fiction to Design Effective Inclusionary Housing Programs. I am not sure fact was fully separated from fiction when I finished reading it.  It opens,

Inclusionary housing programs generally refer to city and county planning ordinances that require or incentivize developers to build below-market-rate homes (affordable homes) as part of the process of developing market-rate housing developments. More than 500 local jurisdictions in the United States have implemented inclusionary housing policies, and inclusionary requirements have been adopted in a wide variety of places—big cities, suburban communities and small towns.

Despite the proliferation of inclusionary housing programs, the approach continues to draw criticism. There have been legal challenges around inclusionary housing requirements in California, Illinois, Idaho, Colorado and Wisconsin, among others. In addition to legal questions, critics have claimed inclusionary housing policies are not effective at producing affordable housing and have negative impacts on local housing markets.

While there have been numerous studies on inclusionary housing, they unfortunately do not provide conclusive evidence about the overall effectiveness of inclusionary housing programs. These studies vary substantially in terms of their research approaches and quality. In addition, it is difficult to generalize the findings from the existing research because researchers have examined policies in only a handful of places and at particular points in time when economic and housing market conditions might have been quite different. Given these limitations, however, the most highly regarded empirical evidence suggests that inclusionary housing programs can produce affordable housing and do not lead to significant declines in overall housing production or to increases in market-rate prices. However, the effectiveness of an inclusionary housing program depends critically on local economic and housing market characteristics, as well as specific elements of the program’s design and implementation.

The brief concludes that, in general, ” mandatory programs in strong housing markets that have predictable rules, well-designed cost offsets, and flexible compliance alternatives tend to be the most effective types of inclusionary housing programs.” (11, emphasis removed)

I have to say that this research brief does not give me a great deal of confidence that mandatory inclusionary zoning programs are going to be all that effective.  Indeed, the conclusion suggests that many ducks need to line up before we can count on them to make a real dent in affordable housing production. While this by no means should imply that they should be curtailed, we should continue to evaluate them carefully to see if they live up to their promise.
