Do Inclusionary Zoning Policies Affect Local Housing Markets? An Empirical Study in the United States

Vince Wang


In recent years, housing affordability challenges have risen to the fore globally. In response to this crisis, many American cities have adopted inclusionary zoning (IZ) policies. Through IZ, local governments typically require or incentivize developers to set aside a share of housing units in new buildings to be rented or sold at below-market rates. Despite its growing popularity, IZ remains a controversial local affordable housing policy. At the center of the debate is this policy’s effect on housing market outcomes. Using a propensity score matching approach coupled with difference-in-differences regression analysis, we examine whether IZ presence as well as policy design affect housing starts, price, and rent. In the CSSS research seminar, I will present data preparation and modeling strategies, as well as preliminary results.
