What is Annexation?
Municipal Boundary Review - Home (contact info)Annexation is the process that transfers unincorporated territory from towns to cities and villages. It is a landowner-driven process. Landowners often seek annexation to obtain sewer and water or other municipal services not available in the town, but there may be other reasons as well.
Wisconsin statutes authorize a number of different annexation methods. Annexation by unanimous approval and by one-half approval are the most common of these methods. They involve:
- a property owner;
- a town(s);
- a village or City; and
- a public interest review by the Department of Administration. See Department Review of Annexations.
The municipal boundary, intergovernmental, and land use issues surrounding annexation may sometimes be contentious. On the other hand, annexation can serve as a gateway to intergovernmental agreement and cooperation. Department staff is available upon request to meet with local officials and citizens to discuss annexation issues and mechanisms for resolving them. One such mechanism is a cooperative boundary agreement, a type of intergovernmental agreement reviewed by the Department. See Cooperative Boundary Agreements.
