Abstract
The purpose of this study is to review the regulations related to the classification of housing use and to propose improvements. The classification for housing use was analyzed from two perspectives : the classification system itself and business value. Confusion regarding the definition of housing was found not only between the Building Act and Housing Act but also among related tax acts. Furthermore, classification issues were identified for detached housing, multi-family housing, and for quasi-housing. To resolve these issues and respond to new types of residential facilities, a new classification system was proposed. Multi-unit houses, multi-household houses, row houses, and apartments were consolidated into multi-family housing to eliminate confusion caused by the number of floors and total floor area limitation for housing use. Multi-user houses and dormitories were classified as newly created share housing to meet the demand for new types of rental housing. Introducing quasi-housing into the Building Act will enable the management of newly emerging residential facilities in the housing market. This study proposes reorganizing the classification oh housing use into four categories : detached housing, multi-unit housing, share housing, and quasi-housing, with practicality, scalability, and sustainability in mind. The findings of this study are expected to inform future government policies or revisions to housing laws and regulations.
