The traditional housing law system of Korea centered on supply and demand, which was formed against the background of rapid urbanization and population growth, could no longer be maintained as the housing supply rate exceeded 100% and the country entered a rapidly declining population. The changed social structure is demanding institutional transformation in the direction of boldly abandoning the ‘construction promotion act’ system in Korean housing legislation, remodeling old apartments, and delicately managing apartments. It is time to discuss the reform direction of the fundamental structure of the housing law system through social consensus and discussion. In this article, we reviewed the process of introducing the institutional function of the current housing law system and its social background, following the historical process of the formation of the framework of Korea's housing law system. When the social reality, which is the foundation of the housing legislation, changes, the function and system of the norm cannot help but change accordingly. In this article, we looked at the achievements of adaptation to the current legislation and future tasks under the premise that the center of gravity of Korean housing law system will inevitably shift to the ‘management function of apartment housing’ for a considerable period of time in the future. The change in Korean society, which has escaped from the desperate housing shortage and is entering a declining population, is an institutional challenge, but on the other hand, it can act as an opportunity to improve the quality of the city. We look forward to the rebirth of the housing law system that upgrades our apartment buildings to a more pleasant environment and a space with efficient and reasonable functions including informatization, away from the perspective of the development era.
