This study aims to clarify the influences of disaster prevention block improvement zone plans and deregulation on rebuilding intentions and problems of disaster prevention. We analyzed the spatial characteristics of deregulated buildings by comparing deregulated and non-deregulated buildings which are constructed after the zone plans were formulated. We grasped the problem of restriction on installation of wall retreat area and the impact of rebuilding intentions from questionnaire surveys of the residents. Deregulation was often applied to buildings in narrow sites or along narrow roads. Although residents were not aware of their homes being deregulated, it is suggested that rebuilding can be promoted by construction companies using deregulation to meet demands of building owners.
