Impact of group homes on the values of adjacent residential properties.

The economic impact of locating small group homes in various single-family residential neighborhoods was assessed. Sales within 229 m of 19 homes, which occurred 24 months prior and subsequent to licensing, were examined using a computer assisted mass appraisal model and an adaptive estimation procedure. The findings confirm earlier studies that refute the notion that such homes adversely impact real estate values of adjacent properties. An extensive review of relevant literature and litigation was provided.
