A study of the impacts of zoning on housing values over time
Using a virtually unique data base for Vancouver, Canada, this study examines the ways in which various zoning classifications and land uses affect the sale prices of single-family residences over a 24-year period. The overwhelming conclusion is that while there are impacts, they are consistent in neither direction nor magnitude. The results suggest that the negative externalities that are generally assumed to exist may in fact not exist. As a result, the use of zoning to control the effects of such presumed externalities may not be justified.
