Abstract This study empirically analyzes the transition in Seoul’s housing supply ratio by type from 2015 to 2024, focusing on housing policy and system changes, demographic shifts, and evolving demand. The research process included a review of major policy and system changes, analysis of demographic trends and housing supply statistics, time-series analysis of their effects on supply ratios, and formulation of future policy directions. Results show that, despite a 6.9 percent decrease in population, the number of households increased by 7.0 percent, reflecting a structural shift toward smaller households. During this period, the supply of non-apartment housing declined sharply, while apartments became dominant after 2018 due to redevelopment policy changes and market conditions. The overall decline in housing supply was largely attributed to the reduction in non-apartment housing, whereas apartment supply remained stable through ongoing redevelopment projects. Based on these findings, three main policy directions are suggested for Seoul: systematic expansion of small and diverse housing types to meet demand, prioritization of universal design and community-based housing to support an aging population, and preservation of medium- and large-sized units for families. In addition, the study emphasizes the importance of pipeline-based monitoring and flexible policy feedback at each stage of the housing supply processs, including approval, construction start, and completion, to enhance policy effectiveness and sustainability.
