In Korea, there is still no plan to secure earthquake-resistant performance in private buildings despite being exposed to the risk of large and small earthquakes. Therefore, this study considered the current status of domestic and foreign support systems as well as prior research on improving the seismic resistance rate of private buildings, and surveys of experts and residents were conducted based on them. According to the survey, direct support such as financial support for seismic reinforcement, technical/administrative support, rental housing support, and deregulation should be considered to improve the seismic resistance rate of private buildings. In addition, it is necessary to prepare a cost-effective plan and review the financial security plan. As social consensus is important for these support systems, continuous policy research is needed.
