In the 2000s, important legal arrangements were made that directly and indirectly concern municipalities. While some laws are specifically regulated for a particular metropolitan area, the Municipal Law and the Metropolitan Municipality Law generally regulated the urban transformation practices of the municipalities. Finally, the Law No. 6306 of 2012 on the Transformation of Disaster Risk Areas has made various regulations through the central administration, the Ministry of Environment and Urbanization and TOKI. Regarding these regulations, the Ministry went to give both financial resources and authority and duties to TOKİ and municipalities. Thus, many actors, such as district municipalities, metropolitan municipalities, ministries and administrations, are authorized to carry out important projects. t is seen that the greatest role in this comprehensive and multidimensional policy field is given to the Ministry, subsequently to the metropolitan municipalities and finally to the district municipalities. In this study, the legislation regulating this multi-actor and complex structure of urban transformation was examined. It is aimed to evaluate urban transformation applications, which have gained a negative image in recent years. As a result, the institutional framework in Turkey has been analyzed and interpreted.
