Democratic Party lawmakers Kim Young-bae, Oh Ki-hyoung and Kim Nam-keun have emerged as leading advocates of shifting the party's Seoul housing policy from regulation toward supply. Representing Seongbuk-A, Dobong-B and Seongbuk-B, they helped design Chung Won-oh's "Chak-Chak Development" platform, which sought to cut redevelopment timelines from roughly 15 years to under 10 and expand floor area ratio exemptions. Their agenda focuses on stalled projects in northern Seoul, where weak project economics, repeated approvals and financing constraints have delayed construction. The lawmakers support transferring selected authority over redevelopment and rebuilding projects involving fewer than 500 units from the Seoul Metropolitan Government to district offices. Existing proposals include delegating district designations and minor project-plan changes, which participants said could save up to three years. The Ministry of Land, Infrastructure and Transport (MOLIT) and the National Assembly are reviewing related revisions, including the threshold, area criteria and integrated deliberation. The lawmakers have also challenged a proposed tax increase for single-home owners who do not live in their properties, while calling for more housing sites, including public land near the former U.S. military base in Yongsan. Their activity has gained political importance as the Democratic Party seeks to improve housing sentiment and address concerns linked to President Lee Jae-myung's declining approval ratings.
