Mandatory Versus Incentive-Based State Zoning Reform Policiesfor Affordable Housing in the United States:A Comparative Assessment

To break the chain of exclusionary zoning and produce affordable housing, mandatory state zoning reform policies have been in place for a couple decades in the United States. Their success is often constrained by local resistance and noncompliance. Some scholars argue that the lack of incentives to communities for affordable housing production is one of the main reasons for their resistance to state mandates. At present, no incentive-based state zoning reform policy is at work except in Massachusetts. Inclusionary zoning policies do offer incentives to developers but not to communities. This article examines the strengths and weaknesses of mandatory state policies and Massachusetts's incentive-based policy and offers policy insights for the future.
