Évaluation de l’effet d’une politique spatialisée d’accès au logement. La loi sru

A French law on solidarity and urban renewal, called the sru law, was voted in December 2000 and imposes medium and large municipalities to have at least 20% of social housing, otherwise they are liable to a fine.?We evaluate its effects for municipalities which population is close to the eligibility threshold.?The sru law would have had a significant positive effect on the construction of social housing which is increasing over time.?For the municipalities in our sample which initially contain social housing, the law would have increased the annual growth rate of the number of social dwellings by 1.25 point on average over the 2000-2008 period.?The effect would have concentrated on municipalities which are initially the furthest from the target of the law, with a proportion of social housing lower than 5% in 2000.?We also find that the law would have led to a decrease in the within-municipality segregation of dwellings according to their type (social or private), maybe because of a more scattered development of social housing.?We are unable to find any effect of the law on housing prices in the resale real estate market.
