This map show the location of the 2172 buildings treated in the context of the policy to combat sub-standard and deteriorating housing between 2002 and 2018 in Paris, in accord with the intervention strategy decided upon. The 449 most rundown buildings were acquired by public authorities and transformed into social housing, while 1723 private buildings were rehabilitated by their owners, with the help of subsidies from the National Housing Agency (Anah) and the City of Paris.
Each building corresponds to a land registry land plot. Buildings were located by using data provided by the City of Paris and the Apur Observatory of the Eradication of Substandard Housing (OEHI).
