Depending on how state and market act on the production of space, the development of certain urban areas occurs or their decay. In response to the decline process, the governments of several cities of the world have been developing urban policies of intervention in these central areas, basically in two ways: through their eradication, or through their rehabilitation. Recently the implementation of social housing policies has been defended as a strategy to cope with city centre decline. The aim of this paper is to analyse the case of São Paulo, Brazil. Over the last hundred and fifty years it has grown very quickly, presenting both rise and decline processes. Since the 1970s the municipality has been implementing several plans in order to revert the decline, and recently with the aim to provide social housing. The paper is divided into this abstract and four more sections. First a little historic appraisal of the public responses to the decline process, followed by a view on the rise and decline of São Paulo city centre. The next section will analyse the policies proposed and implemented by the municipality for the centre and then analyse the implementation of ZEIS 3, a type of inclusionary zoning, searching to understand it results in a rehabilitation process. This paper is partially result of a post-doctoral research project financed by FAPESP (São Paulo State Research Support Foundation), Process # 2015/26447-7.EnglishopenAccessconferenceObject1831-1841
