This study aims to diagnose construction and operational issues arising from the establishment of the rental-type dormitory category and develop improvement measures for rational system operation. To achieve this, we will ➊analyze the current institutional status of similar-use buildings and compare it with existing rental-type dormitory regulations to identify relevant issues, and ➋analyze self-regulatory operations and licensing status related to rental-type dormitories to uncover systemic limitations and problems. Additionally, we will analyze building committee review opinions on approved cases and gather feedback from local government licensing officials to specify areas requiring institutional improvement and establish improvement directions. ➌Through simulation applying similar-use building regulations to cases and improvement needs identified in the research process, we will derive system improvement measures and ➍propose institutional improvements by gathering opinions from field experts and relevant stakeholders.
