City commission government

City commission government is a form of local government in the United States. In a city commission government, voters elect a small commission, typically, from five to seven members, on a plurality-at-large voting basis.

These commissioners constitute the legislative body of the city and, as a group, are responsible for taxation, appropriations, ordinances, and other general functions. Individual commissioners are also assigned executive responsibility for a specific aspect of municipal affairs, such as public works, finance, or public safety. As such, this form of government blends legislative and executive branch functions in the same body.

One commissioner may be designated to function as chairman or mayor, but this largely is a procedural, honorific, or ceremonial designation and typically, does not involve additional powers beyond that exercised by the other commissioners. Chairing meetings is the principal role. Such a "mayor" is in many ways similar to the "weak mayor" form of mayor–council government, but without any direct election for the office. However, some cities with this form of government, such as Portland, Oregon, have an elected mayor.

This form of government originated in Galveston, Texas as a response to the Galveston Hurricane of 1900, mainly for the reason that extra support was needed in certain areas. After its constitutionality was tested and confirmed, this form of government quickly became popular across the state of Texas and spread to other parts of the United States.

Des Moines, Iowa became the first city outside Texas to adopt this form.
