A charter township is a form of local government in the U.S. state of Michigan. Townships in Michigan are organized governments. A charter township has been granted a charter, which allows it certain rights and responsibilities of home rule that are generally intermediate between those of a city (a semi-autonomous jurisdiction in Michigan) and a village, which, unless it is a home-rule village, is subject to the authority of any township in which it is located.
In 1947, the state legislature created a special charter township status, which grants additional powers and streamlined administration in order to provide greater protection against annexation of a township's land by cities and villages. As of November 2014, there were 117 charter townships in Michigan. A township with a population of 2,000 or more may incorporate as a charter township and become a municipal corporation, which possess all the powers of a non-charter township in addition to those specified by the Charter Township Act of 1947.
Legislative authority is exercised by a township board of seven members consisting of the supervisor, the township clerk, the township treasurer, and four trustees who are eligible to vote in elections and are residents of the township. All members of the board serve four-year terms. Unlike the boards for general law townships, which may have either five or seven members, a charter township must have seven members. If a general law township with a five-member board elects to become a charter township, two additional members are to be elected in the next general election.
Charter townships may appoint either a township superintendent or township manager, who can be assigned responsibilities for managing township functions (this is comparable to cities that utilize a city manager to oversee the day-to-day operations of the city). Otherwise, executive authority lies with the supervisor, and various committees.
A charter township may establish a variety of municipal services, such as a police force, fire department, assessors and also acquire property. It may also borrow money and issue bonds, with the approval of a majority of township voting in an election. Similarly, a charter township cannot levy taxes without the approval of a majority of the township population voting in an election. This is one significant difference from home-rule municipalities, in which the municipal authority can levy taxes without specific approval from voters.
A charter township is mostly exempt from annexation from contiguous cities or villages providing that the township meets certain requirements:
