Seoul says it aims to secure a net increase of about 87,000 homes by 2031 across 253 redevelopment zones while also reviewing an expansion of its Youth Safe Housing program that could add 17,500 units by 2030 by widening eligible transit-zone areas from 250 meters to 500 meters. Mayor Oh Se-hoon argued that redevelopment and reconstruction are essential in land-constrained Seoul, rejected building housing in Yongsan Park, and said annual relocation demand of a little over 20,000 households can be managed despite pressure on jeonse and monthly rents. The city said seven private redevelopment projects in Seogye-dong and Cheongpa-dong are under way, with six of them planned to raise housing to 8,088 units from 6,393, a net gain of 1,695 homes, or 26.5%, excluding Cheongpa 3 District where unit numbers are not yet fixed. Separately, Youth Safe Housing had 33,621 operating units across 101 sites as of end-July, with public rentals priced at 30% to 50% of nearby market rates and publicly supported private rentals at 75% to 85%, amid strong demand reflected in a 105-to-1 average competition ratio in this year's first public-rental tenant recruitment. Seoul is also seeking policy changes to improve redevelopment economics, including lower rental-housing quotas, higher floor area ratios, easier relocation-loan LTV terms and looser association-formation rules, while boosting youth housing support through higher construction-fund interest compensation, a temporary cut in the public contribution ratio, rent and maintenance subsidies, and broader deposit-loan interest support. The city said it plans 74,000 youth-focused housing units by 2030 in total, including about 25,000 new units such as 10,000 Seoul-style SaeSsak studios and 2,000 Didimdol homes.
