Annexation and Boundary Adjustments

Annexation

Annexation is a legal process that allows property located in an unincorporated township to be incorporated into a neighboring city or village. Annexation petitions and filings follow a defined procedure, established under Chapter 709, to ensure accurate record-keeping and compliance with state regulations.

If a proposed annexation is approved, the auditor or clerk of the impacted municipal corporation must file copies with the county auditor, county recorder, and the Secretary of State. This ensures the annexation is legally recognized and recorded at all levels.

Annexation Petition Requirements

Reference: R.C. 709.39

An annexation petition must include all necessary documents and maps, prepared in accordance with state requirements. Petitions must be printed on single-sided letter or legal-size paper.
