National Assembly Housing Supply Acceleration Act Tracker Shows Seoul's Permit Timelines Compared to Busan and Incheon
Seoul households face revised approval processes for new apartment projects as the legislation sets uniform national standards while allowing city-specific implementation details.
How we reported this
The National Assembly passed the Housing Supply Acceleration Act last month, requiring Seoul city officials to process residential development permits within 120 days for projects exceeding 300 units. This change directly affects residents in districts such as Gangnam and Mapo where multiple redevelopment sites await approval.
The legislation emerged after the Ministry of Land, Infrastructure and Transport reported a 18-month average delay for housing permits across major cities in 2025. Seoul's metropolitan government must now align its review procedures with the new national timeline while retaining authority over local density rules.
Permit Processing Changes for Seoul Residents
Local residents seeking new housing will encounter streamlined application windows at the Seoul Metropolitan Government building. Families in Nowon-gu, for example, can track project status through the city's online portal rather than waiting for separate district-level reviews. Commercial tenants near construction zones may see earlier notification of site work start dates.
Seoul's implementation requires developers to submit digital environmental impact statements 30 days earlier than under prior rules. In comparison, Busan city has adopted a 90-day target for similar projects while Incheon maintains its existing 150-day window for waterfront developments. These differences mean Seoul-based contractors may redirect resources toward faster-track sites in the capital.
The 2026 Seoul budget allocates 1.4 trillion won to housing-related administrative staffing, according to the city's published fiscal plan. This figure supports additional reviewers needed to meet the national deadline without expanding overall city expenditure.
City staff will begin full enforcement on August 15. Residents can monitor individual bill amendments through the National Assembly's public tracker, which lists Seoul-specific clauses on zoning exemptions. Further updates will appear in monthly reports from the Seoul Metropolitan Council housing committee.
