Housing Supply and Affordability: Do Affordable Housing Mandates Work?

This study attempts to fill the research void. In this paper we use data from communities in the San Francisco Bay Area region to evaluate the effects of inclusionary zoning and examine whether it is an effective public policy response to high housing prices. We chose the Bay Area because inclusionary zoning is particularly prevalent there; today more than 50 jurisdictions in the region have inclusionary zoning. These communities have various sizes and densities with different income levels and demographics, so they provide a good sample to tell us how inclusionary zoning is probably working nationwide.
