There have been passed 50 years since the Restricted Development Zone (RDZ), being designated in the Capital Region. The aim of the study is to focus on the historical perspectives on the policy changes in the RDZ. These 50 years can be divided into five periods, according to the characteristics affected in the residents of the RDZ. The first is the Introduction Period of the RDZ with strict management between 1971 and 1979. The second is the Maintenance and Deregulation Period of the RDZ between 1980 and 1997. The third is the Adjustment of RDG and Preparation Period between 1998 and 2002. The fourth is the Removal of RDG for the existing villages and the Housing Development of the National Project Areas between 2003 and 2012. The fifth is the Maintenance Strengthening Period of the RDZ, not allowing additional removal of the RDZ after 2013.

Human settlements in the RDZ are classified into Villages of Single Detached Houses reconstructed by the Community Structure Improvement Projects, the Newly Developed Areas of high rised apartment complexes by the National Project, the Gradually Changing Villages by the Detailed Area Plans, the Remaining Villeges without Redevelopment, relocation areas of low-income residents. The study shows the issues by the policies for the residents and lands of the RDZ in each time period. The issues are derived by the types of villages in the RDZ.
