Westerville is situated within multiple counties. The city primarily resides in Franklin County, but portions of Westerville also extend into Delaware County. A small section also falls within Fairfield County. Determining the specific county location is dependent on the precise address within the city’s boundaries.
Understanding the jurisdictional boundaries is important for various administrative and governmental processes. County location affects property taxes, voting districts, access to county-specific services (such as health departments and social services), and law enforcement jurisdiction. Historical factors, including annexations and urban expansion, contribute to this multi-county configuration.
