Municipal annexation is the territorial expansion of a municipality’s corporate boundaries.  In Ohio, the process of annexation is regulated by the Ohio Revised Code (chapter 709) and is administered locally by the County in which the property is located. The specific County contact varies, but in Franklin County, the County Economic Development and Planning Department serves as the annexation coordinator.  

Timing of the annexation process requires that applicants initiate review by the City prior to formal application with the County. It includes a number of administrative steps as well as legislative actions by the municipal council and county commissioners.   The City of Columbus considers all annexation petitions on a case by case basis.  The Annexation Process Guide outlines the steps typically involved in annexing territory to the City of Columbus. The steps included in this outline are focused on the requirements of the city itself. 

Additional steps are required by the county of jurisdiction in accordance with ORC 709. Applicants must contact the appropriate county for information regarding additional process requirements and alternative annexation types. Columbus does not require an application fee, however County fees may apply. 

Please note that annexation impacts a property’s real estate tax obligations, electoral status, availability of municipal services, and school district status among other things.  It is important for applicants to be informed about these issues prior to moving forward with an application.
