W3tr, 10,000 civil servants: The hurdles facing South Korea's Sejong relocation plan

The government has laid out a concrete plan to relocate 44 central administrative agencies and 9,929 civil servants from the greater Seoul area to Sejong by 2031, aiming to establish the city as a genuine administrative hub. But the path forward is strewn with obstacles — from legal constraints on the agencies slated to move, to a construction bill in the 3 trillion won ($2.24 billion) range, to the challenge of settling thousands of government workers in a new city.

The most pressing task is establishing a legal basis for the move. Agencies including the Ministry of Foreign Affairs, Ministry of Unification, South Korea's Ministry of National Defense, Ministry of Justice and the Ministry of Gender Equality and Family are explicitly listed as exempt from relocation under the current Happy City Act. Without an amendment passing the National Assembly, moving those agencies would be legally impossible. Alongside revising the Happy City Act, the government must also push to enact a special administrative capital law to give Sejong's status as an administrative capital a formal institutional footing. After that, the relocation plan must be revised and officially announced following mandatory procedures including consultations with relevant agencies and public hearings. Any delay in amending the law could have a cascading effect on the timetable for individual agencies and plans to secure office space.

Securing a vast budget and expanding the capacity to house the incoming agencies are equally daunting challenges.

The government estimates that early relocation costs using leased office space in 2027 will reach 89.7 billion won, with total project costs for constructing independent buildings and other facilities coming to about 3.1 trillion won. Because leased offices will need to operate for three to four years until new buildings are completed, additional costs will arise. A comprehensive fiscal plan covering not just the initial relocation expenses but also long-term rental fees and construction costs will be essential.

Finding space for the incoming agencies in the immediate term is another challenge. Until new buildings are ready, the government will need to accommodate agencies without any operational gaps — through measures such as rezoning private office space in Sejong and redistributing available space within Government Complex Sejong.

The relocation will proceed in stages from 2027 to 2031. In the first half of 2027, six agencies will move first: the Korea Communications Commission, the Personal Information Protection Commission, the Nuclear Safety and Security Commission, the National Human Rights Commission, the National Education Commission and the Overseas Koreans Agency. In the second half of the year, 19 agencies are set to follow — including the Financial Services Commission and various ministry-affiliated bodies and advisory committees — along with agencies such as the Ministry of Justice and the Ministry of Gender Equality and Family that will move into leased offices. A further 17 agencies requiring independent buildings or specialized facilities — among them the Ministry of Foreign Affairs, Ministry of Unification, Defense Ministry, Board of Audit and Inspection, Korean National Police Agency, the Public Prosecution Service and the Serious Crime Investigation Agency, accounting for 6,934 staff — will relocate sequentially by 2031 after their new buildings are completed.

Given that this is a long-term undertaking spanning five years, minimizing administrative disruption throughout the process is critical. Agencies with close ties to financial markets, such as the Financial Services Commission, must maintain continuity in policy responses and licensing and permit services even as they move. There are also concerns that junior staff in particular may resign ahead of the Sejong relocation. Operational guidelines will be needed to prevent the departure of key specialists and to minimize inconvenience for citizens and businesses.

The settlement conditions for employees will be another factor that determines whether the relocation succeeds. The government plans to provide moving allowances and initial relocation support, and is considering temporary commuting subsidies for staff who cannot relocate immediately due to housing needs or their children's school schedules. However, the details — including the scale and duration of support — have yet to be finalized. For the employees affected, the move means more than just a change of workplace; it requires a wholesale reorganization of their lives, covering housing costs, commuting and their children's education. If the support measures arrive too late or fall short of what workers actually need, the result could be employee resistance and delays in settlement.

Sejong's current population stands at about 390,000, still short of the planned target of 500,000, and critics point out that public transportation, healthcare, cultural amenities and educational infrastructure remain inadequate. Essential facilities — including more public nurseries and schools, and the recruitment of a general hospital — must be built out. Without an environment where civil servants and their families can genuinely live and put down roots, the agency relocations are unlikely to translate into the broader regional economic benefits of local settlement, increased consumption and job creation.

The real test is whether the move can deliver on its stated goals of easing the concentration of resources in the greater Seoul area and revitalizing regional economies, rather than simply shifting agencies from one place to another. The first wave of relocations, which began in 2012, turned Sejong into an administrative city with a critical mass of central government agencies and civil servants. Yet the concentration of population and economic activity in the greater Seoul area continued unabated: the greater Seoul area's share of the national population rose from 49.3 percent in 2010 to 51 percent in 2025, while its share of economic output climbed from 50.1 percent to 52.8 percent over the same period. This round of relocations must go beyond the movement of agencies and personnel to deliver tangible results — improving inter-ministry collaboration and policy efficiency, and fostering self-sustaining industries and jobs centered on Sejong. With more than 3 trillion won in public funds committed and years of disruption to absorb, the question of how to measure and demonstrate gains in administrative efficiency and balanced regional development remains an open one.
