40B Report: Effects of Mixed-Income, Multi-Family Rental Housing Developments on Single-Family Housing Values

April, 2005

Do mixed-income, high-density rental developments negatively impact nearby single family property values? This question has been at the core of the controversies surrounding mixed-income housing in suburban Boston communities. Chapter 40B, enacted through the Comprehensive Permit Law and Anti-Snob Zoning Act, is a Massachusetts statute that enables developers to obtain state-authorized comprehensive permits in municipalities that are not in compliance with state affordability criteria: If less than ten percent of a municipality’s housing stock is defined as affordable, developers with comprehensive permits can build developments that override local zoning regulations. Because zoning rules are viewed by some as regulatory mechanisms that protect property values by controlling local land use, the ability of developers to circumvent such regulations has given rise to fears that the values of homes surrounding these mixed-income, multi-family developments will decline. These fears are considered one of the strongest motives for residents’ opposition to proposed 40B developments. But are such fears justified by the facts?  This is the question investigated by CRE’s Housing Affordability Initiative (HAI) in this 40B Report.
