Abstract
The purpose of this paper is to investigate the present conditions and problems of the urban redevelopment projects started before and after the legislation of the urban redevelopment law. We conducted surveys through questionnaires and interviews to the local authorities and managements of the redeveloped buildings. The results of our research clarified the following issues: 1) most of the redeveloped buildings are recognized to be decrepit and obsolescent, 2) the system of managing floors of the redevelopment buildings as joint property faced difficulties caused by increasing vacant floors, 3) it is necessary for the public sector to involve in revitalizing the old redeveloped buildings.
