Mexico, the county's towns, and Audrain's local government layers
An Audrain County address can sit inside or outside an incorporated city and within several overlapping special districts, which determines who provides services and which taxes apply.
An address in Audrain County may sit inside an incorporated city or town, like Mexico, or out in unincorporated county land. That difference matters. It changes who provides your services and which local rules apply.
On top of the city-or-county line, your parcel can fall inside several special districts. These often include a school district, a fire protection district, an ambulance district, a library district, and a road, water, or sewer district. Each one has its own boundaries. Many also charge their own tax, called a levy.
Audrain County’s incorporated communities include Mexico, Vandalia, Laddonia, Farber, Martinsburg, Benton City, and Rush Hill. The county also has small unincorporated areas.
Before you assume what services or taxes apply, find out exactly which city and which districts cover your parcel. Use the county’s GIS property tool or ask the county clerk instead of guessing from the address.
