The Village of Belleville is governed by a Council/Administrator form of government. This form of government is the most popular structure of government in the United States among municipalities. Under this form, the residents of Belleville elect the Village Board to adopt legislation and set policy. Trustees are elected at-large and sit on various committees and commissions along with citizens that the Board appoints. 

The Village Board then hires the administrator with the executive authority to carry out those policies and oversee the local government's day-to-day operations.
