State preemption and affordable housing policy

Many affordable housing policies are the domain of local governments. While subnational housing policies can be used to increase racial and economic segregation, they can also protect renters, and thus are not without controversy. Local affordable housing policies include inclusionary zoning, rent control, short-term rental regulation and source of income discrimination. Starting in the 1980s, states began to preempt these local laws, preventing their cities from adopting affordable housing policies. We ask why states choose to preempt one or more of these four affordable housing policies. Using a cross-sectional, time-series dataset of preemptions, we find evidence that more conservative legislatures are more likely to adopt preemptions, while more professional legislatures and states with higher rental rates and previous preemptions are less likely to preempt. Contrary to expectations, interest group density, electoral competition and policy diffusion are not significant predictors of preemption. For advocates and policymakers concerned with increasing affordable housing in their jurisdictions, these results raise unease about the ability to further an affordable housing agenda at the local level, particularly in more conservative political environments, suggesting instead that affordable housing may need to return to the purview of the federal government.
