Law and government 
The city operates under a mayor-council system of government (with a caveat, below). Byron is divided into four wards, each of which elects two alderman, giving the city an eight-member council. The eight members of the council are organized into five committees with specific responsibilities, necessarily, given the number of council members, committee memberships overlap.
Elected separately, by the whole city, is the mayor. The mayor's powers include the right to appoint members of the five standing committees, and to preside over council meetings. He may also call special meetings of the council. The mayor receives an annual salary of $9000.
The city also has other elected officials, including a city clerk and a treasurer. There are also unelected paid positions; these are filled by appointment of the mayor. These include the comptroller and the city attorney.
Despite the fact that Byron has a mayor-council system of government, the municipal code for Byron contains a provision whereby a city administrator may be appointed, if the mayor and council so desire. To date, this provision has not been placed into effect.
