Measuring the effects of mixed land uses on housing values

Mixing land uses has become one of the key planning principles of the Smart Growth movement and other land use planning strategies. This article analyzes the impact on the prices of single family houses when mixed land uses are included in neighborhoods. We first develop several quantitative measures of mixed land uses through the use of Geographic Information System (GIS) data and compute these measures for various neighborhoods in Washington County, OR. We then incorporate those measures in a hedonic price analysis. We conclude from this research that housing prices increase with their proximity to—or with increasing amount of—public parks or neighborhood commercial land uses. We also find, however, that housing prices are higher in neighborhoods dominated by single-family residential land use, where non-residential land uses were evenly distributed, and where more service jobs are available. Finally, we find that housing prices tended to fall with proximity to multi-family residential units.
