National Assembly: Korea’s Legislative Body and Housing Policy Authority

Organization Overview

The National Assembly of the Republic of Korea (대한민국 국회) is the unicameral legislative body that exercises supreme legislative authority over every dimension of Korean public policy, including the legal frameworks governing housing, urban planning, land use, transportation, and population strategy that collectively shape the 2030 Seoul Plan. Comprising 300 members representing both geographic constituencies and proportional representation party lists, the National Assembly enacts the laws that define the authority of the Seoul Metropolitan Government, the operational mandates of LH Corporation and SH Corporation, the regulatory framework of the Ministry of Land, and the fiscal systems that fund metropolitan development. No institution in Korea exercises greater formal authority over the legal architecture of urban planning.

Constitutional Authority and Legislative Framework

The National Assembly’s authority is established by Chapter III of the Constitution of the Republic of Korea. Article 40 vests legislative power in the National Assembly. Article 54 grants the Assembly exclusive authority to approve the national budget. Article 61 provides the power of governmental inspection and investigation. Article 63 enables the Assembly to recommend the removal of the Prime Minister or State Council members. These constitutional provisions establish the National Assembly as the supreme oversight body for executive branch institutions including the Ministry of Land, Ministry of Population Strategy, and all national public corporations.

The legislative process for housing and urban planning policy typically begins with bill introduction by either the executive branch (government bills) or individual assembly members (member bills). Bills are referred to the relevant standing committee — the Land, Infrastructure and Transport Committee for housing, zoning, and transportation legislation, or the Strategy and Finance Committee for tax and fiscal legislation — for review, public hearings, expert testimony, and markup. Committee-approved bills proceed to the plenary session for final vote. The president may exercise a limited veto, which can be overridden by a two-thirds majority.

Key legislation enacted by the National Assembly that shapes the 2030 Seoul Plan framework includes:

The National Land Planning and Utilization Act (국토의 계획 및 이용에 관한 법률), which establishes the national zoning framework, defines land use categories, and sets the parameters within which metropolitan governments can exercise planning authority. This act is the legal foundation for Seoul’s urban master plan.

The Housing Act (주택법), which governs housing construction standards, supply quotas, public-private development partnerships, and the apartment pre-sale (분양) system that structures the Korean housing development industry.

The Special Act on Public Housing (공공주택 특별법), which provides the legal basis for LH Corporation’s and SH Corporation’s public housing programs, defines eligibility criteria for public housing tenants, and establishes the financing mechanisms for public housing construction.

The Local Autonomy Act (지방자치법), which defines the authority, organization, and fiscal framework of metropolitan and local governments including the Seoul Metropolitan Government and the 25 autonomous districts.

The Act on Acquisition of and Compensation for Land for Public Works, which establishes the compulsory purchase and compensation framework used by LH Corporation and other development agencies for land acquisition.

The Real Estate Transaction Reporting Act and associated tax legislation, which establish the disclosure, taxation, and regulatory framework for property transactions, including acquisition tax, comprehensive real estate holding tax, capital gains tax, and the jeonse deposit guarantee system.

Historical Role in Housing and Urban Policy

The National Assembly’s role in housing and urban policy has evolved dramatically across Korea’s political history. During the authoritarian period (1948-1987), the Assembly functioned largely as a rubber stamp for executive branch initiatives, with limited independent legislative capacity. Housing and planning legislation during this era was effectively drafted by the bureaucracy and enacted with minimal parliamentary deliberation.

The democratic transition of 1987 and the subsequent expansion of legislative independence transformed the Assembly’s role. The introduction of genuine multi-party competition, independent committee staffing, public hearing requirements, and media scrutiny of legislative proceedings created a policy environment in which housing and planning legislation became subject to substantive debate, amendment, and political bargaining.

The 1990s saw the Assembly exercise its legislative authority in response to housing market crises, enacting the Special Act for Housing Price Stabilization (1990), strengthening the Apartment Price Ceiling System (분양가상한제), and establishing the legal framework for the first-generation new town program. These legislative interventions reflected the growing political salience of housing affordability as Korea’s emerging middle class experienced the gap between aspirational homeownership and actual market affordability.

The 2000s brought legislative attention to the diversification of housing policy instruments. The Assembly enacted legislation creating the National Rental Housing program, the Long-Term Jeonse Housing program, and the Housing Voucher program — expanding the toolkit beyond construction-oriented approaches toward a more comprehensive housing welfare framework. The establishment of the National Housing Fund as a statutory special purpose fund provided dedicated financing for public housing programs.

The most legislatively active period in recent housing policy occurred during the Moon Jae-in presidency (2017-2022), when the Assembly enacted approximately 29 sets of housing market stabilization measures including: multiple rounds of loan-to-value (LTV) and debt-to-income (DTI) tightening; expansion of designated speculative overheated zones; strengthening of the comprehensive real estate holding tax; tightening of apartment reconstruction regulations; and new restrictions on multiple-property ownership. This legislative agenda reflected the ruling party’s ideological commitment to demand-side regulation, though its effectiveness in stabilizing housing prices was widely debated.

The Yoon Suk-yeol government (2022-present) has pursued the opposite legislative direction, seeking to relax many of the demand-side regulations enacted during the Moon era while expanding supply-side measures including greenbelt release, reconstruction deregulation, and new town development. The resulting legislative oscillation — between demand-side and supply-side approaches, between regulation and deregulation, between market intervention and market facilitation — is the defining feature of the National Assembly’s contemporary housing policy role.

Standing Committees and Housing Policy Process

The Land, Infrastructure and Transport Committee (국토교통위원회) is the primary standing committee for housing and urban planning legislation. The committee’s jurisdiction encompasses all legislation related to the Ministry of Land, LH Corporation, Korea Rail Network Authority, and other agencies under MOLIT’s supervisory authority. The committee conducts annual inspections of MOLIT and its affiliated agencies, reviews the ministry’s budget request, and processes all housing, planning, and transportation legislation.

The Strategy and Finance Committee handles tax legislation that affects the housing market, including acquisition tax, holding tax, capital gains tax, and transaction tax. Given the enormous role that tax policy plays in shaping housing market behavior — particularly speculative investment — the Finance Committee’s decisions often carry greater practical impact on housing affordability than the Land Committee’s regulatory legislation.

The Public Administration and Security Committee oversees the Local Autonomy Act and other legislation governing metropolitan and local governments, making it relevant to the governance framework within which the Seoul Metropolitan Government and the 25 gu districts operate.

The Budget and Accounts Special Committee reviews the national budget in its entirety, including the appropriations that fund MOLIT’s housing and transportation programs, national transfers to local governments, and the National Housing Fund. The committee’s decisions about spending levels directly determine the fiscal resources available for the 2030 Seoul Plan’s nationally funded components.

Oversight of Public Corporations

The National Assembly exercises oversight over Korea’s public corporations, including LH Corporation and the other agencies that implement housing and transportation policy. The annual governmental inspection (국정감사) — conducted by standing committees over approximately 20 days each fall — provides the primary formal mechanism for legislative oversight.

The 2021 LH Corporation land speculation scandal demonstrated both the importance and the limitations of Assembly oversight. The scandal, in which LH employees were found to have purchased land in advance of publicly announced development zones, was initially uncovered by journalists and civic groups rather than by legislative oversight. However, the Assembly’s response — including multiple rounds of committee hearings, witness testimony, legislative reforms, and demands for executive accountability — demonstrated the institution’s capacity for reactive oversight and corrective legislation.

Post-scandal legislative reforms enacted by the Assembly include: the Act on Prevention of Public Sector Land Speculation, which restricts land transactions by employees of development agencies; enhanced financial disclosure requirements for senior officials of public corporations; strengthened whistleblower protection laws; and expanded audit authority for the Board of Audit and Inspection over public corporation land transactions.

Budget Authority and Fiscal Impact

The National Assembly’s budget authority is the ultimate fiscal determinant of public investment in housing, transportation, and urban development. The annual national budget — approximately KRW 640 trillion in fiscal year 2025 — allocates funding across all government ministries and programs, including the KRW 55+ trillion allocated to the Ministry of Land and its affiliated programs.

Specific budget items with direct relevance to the 2030 Seoul Plan include: appropriations for the GTX express rail program (KRW 2-3 trillion annually during the construction phase); National Housing Fund capitalization and lending authority (KRW 30+ trillion in assets under management); national subsidies for public rental housing construction (allocated to both LH Corporation and SH Corporation); urban regeneration program grants; and fiscal transfers to the Seoul Metropolitan Government through the local share tax and national subsidy systems.

The Assembly’s tax legislation authority has equally significant fiscal implications. Decisions about property tax rates, capital gains tax exemptions, acquisition tax levels, and comprehensive real estate holding tax parameters shape the economic incentives facing property owners, developers, and investors throughout the Seoul housing market.

Political Dynamics and Housing Policy

Housing policy is one of the most politically potent issues in Korean electoral politics, ensuring that the National Assembly’s approach to housing legislation is shaped as much by electoral calculation as by policy analysis. The Korean electorate — in which the majority of household wealth is held in real estate — is intensely sensitive to housing price movements, making housing policy a reliable determinant of electoral outcomes.

The political geography of housing policy creates distinctive legislative dynamics. Members representing Seoul and Sudogwon constituencies (approximately 120 of 300 seats) face direct constituent pressure on housing affordability, transportation access, and development regulation. Members representing non-Sudogwon constituencies tend to prioritize balanced national development and resist policies that they perceive as concentrating resources in the Seoul Capital Area.

The progressive-conservative ideological divide maps onto housing policy in predictable ways. Progressive parties generally favor demand-side regulation (tighter lending standards, higher holding taxes, stricter speculation controls) and expanded public housing programs. Conservative parties generally favor supply-side expansion (greenbelt release, reconstruction deregulation, new town development) and market-friendly regulatory approaches. The alternation of government between these ideological tendencies produces the policy oscillation that has characterized Korean housing policy over the past two decades.

Relationship with Seoul Metropolitan Government

The National Assembly’s relationship with the Seoul Metropolitan Government operates through both formal and informal channels. Formally, the Assembly enacts the legal framework within which the metropolitan government operates, appropriates the national funding that constitutes approximately 28% of Seoul’s budget, and exercises oversight over nationally funded programs implemented within Seoul.

Informally, Assembly members representing Seoul constituencies maintain close relationships with metropolitan government officials, advocating for constituent interests in budget allocation, regulatory flexibility, and project prioritization. The mayor of Seoul, while not a member of the Assembly, is typically a prominent figure in national politics with significant influence over the legislative agenda through party channels.

The interaction between Assembly legislation and metropolitan implementation creates the policy framework within which the 2030 Seoul Plan operates. National laws set the parameters; metropolitan plans fill the parameters with specific spatial strategies, supply targets, and implementation programs. When national legislation changes — as occurs with each shift in political administration — the metropolitan plan must adapt, creating the planning instability that is both a consequence of democratic governance and a challenge for long-term urban development strategy.

Strategic Outlook

The National Assembly’s strategic significance for the 2030 Seoul Plan lies in its capacity to either enable or constrain the plan’s implementation through legislative and budgetary decisions. Key legislative uncertainties include: the future trajectory of greenbelt regulation (will further release be authorized?), the regulatory framework for apartment reconstruction (will the process be further streamlined?), the tax treatment of real estate transactions and holdings (will taxes rise or fall?), and the fiscal commitment to major infrastructure projects including the GTX express rail system.

The demographic crisis is emerging as a potentially transformative factor in the Assembly’s approach to housing and urban policy. The Ministry of Population Strategy has elevated population decline to a national emergency, and the Assembly’s response — through expanded family support programs, housing assistance for young families, and regional population distribution policies — will shape the demand context within which the 2030 Seoul Plan operates.

The National Assembly’s institutional capacity for evidence-based housing policy analysis remains a concern. Committee staff resources are limited relative to the technical complexity of housing market dynamics, and members’ dependence on interest group lobbying and media narratives rather than rigorous policy analysis risks legislative outcomes that exacerbate rather than resolve housing market dysfunction.

The National Assembly Budget Office

The National Assembly Budget Office (NABO; 국회예산정책처) provides independent analytical capability that partially compensates for the limited committee staff resources. NABO produces cost estimates for proposed legislation, evaluates government spending proposals, and conducts policy research on topics including housing market analysis, infrastructure investment evaluation, and fiscal sustainability assessment.

NABO’s analyses of the housing market — including evaluations of the effectiveness of government stabilization measures, cost-benefit assessments of new town development programs, and fiscal risk analyses of LH Corporation’s debt trajectory — provide Assembly members with independent information that balances the executive branch’s policy advocacy. NABO reports have been particularly influential in debates over the fiscal implications of the GTX express rail program, the sustainability of the National Housing Fund’s lending operations, and the long-term fiscal impact of the demographic crisis on housing demand and government revenue.

The Budget Office’s analyses are publicly available and regularly cited by media, academic researchers, and civic organizations, contributing to the transparency of the legislative process and the quality of public discourse on housing and urban policy. However, NABO’s limited staff and the breadth of topics it must cover constrain its ability to provide the depth of analysis that complex housing market dynamics require.

Constitutional Limitations and Reform Proposals

The National Assembly operates within constitutional constraints that shape its capacity to address housing and urban policy challenges. The constitutional guarantee of property rights limits the scope of regulatory intervention in the housing market, as courts may strike down legislation that constitutes an excessive restriction on property rights without adequate compensation. The greenbelt designation, apartment reconstruction regulations, and speculative investment controls have all been subject to constitutional challenge on property rights grounds.

The constitutional convention that Seoul is Korea’s capital — affirmed by the Constitutional Court’s 2004 ruling that blocked full capital relocation to Sejong City — constrains the spatial restructuring options available to policymakers. The Assembly cannot legislate the relocation of its own institution without a constitutional amendment requiring a two-thirds supermajority, a threshold that has not been achievable in Korea’s divided political landscape.

Reform proposals that have been debated but not enacted include: regional legislative quotas that would ensure representation of housing-stressed constituencies; independent housing market advisory bodies with legislative mandate; mandatory long-term fiscal impact assessments for all housing legislation; and constitutional amendment to define housing as a fundamental right rather than merely an economic commodity.
