Public support for planning programs and initiatives are an important component of its success but opposition can be a powerful impediment. When siting unwanted land uses such as affordable housing, neighborhood opposition can be a particularly effective barrier. Understanding the factors that influence opposition is a necessary precursor to successful planning initiatives. This review discusses how attitudes toward affordable housing are likely shaped by factors that influence other social policy attitudes— particularly ideology and stereotyping. The author concludes with recommendations and methods that planners can use to manage public opposition and influence attitudes toward affordable housing. The cost and quality of one’s housing are among the most important factors influencing quality of life in America. Housing represents the largest expense as well as the largest investment for most households (Burchell and Listoken 1995). When housing is unaffordable, overcrowded, or unhealthy, it can affect the financial, educational, and emotional well-being of individuals and families (Bratt 2002; Dunn 2000; Rivkin 1994). When poor households and low-quality housing is concentrated in a single area, the negative ramifications of individual housing challenges substantially increase (Galster 2005; Jargowsky 2006; Squires and Kubrin 2005).
