In the Gangnam-gu council member, one chairperson and one vice chairperson are elected from among the council members through a secret vote, and the term of the chairperson and the vice chairperson is two years.
The chairperson represents the Gangnam-gu Council, regulates proceedings, maintain order, and supervises its affairs.
In case of an accident to the chairperson, the vice chairperson should act for the chairperson.

In response to the fact that local administration is complicated and thus requires expertise, the Standing Committee, as a conference body, is composed of a small number of council members who have expertise in respective areas. They effectively address matters in each area of their expertise.
The Standing Committee examines bills and petitions that fall under their respective jurisdictions, and examines particular matters entrusted by the local council. Also, the Standing Committee begins its session when the chairperson deems it necessary, or when 1/3 or more of registered members demands it.
The Gangnam-gu Council has currently organized three standing committees: the Operation Committee, the Administration & Finance Committee and the Public Welfare & Urban Construction Committee.

In order to temporarily examine and dispose of particular bills, the Council may establish the Special Committee. The Special Committee is, in general, established temporarily in order to examine budget bills and settlement of accounts.
In order to organize the Special Committee on Budget and Accounts, 14 members are elected from each committee and finally decided in the plenary session.
The chairperson and the executive secretary of the Special Committee are elected and carry out activities in the same way as with the Standing Committee.

For the assistance of council activities, the Council Secretariat consists of the Chief Executive Office, committee adviser, Administrative Affairs Division, Proceedings Division and Public Information Division.
