The establishment of Jefferson County in 1818 marked the beginning of organized local governance in this part of Missouri during the early years of statehood.
The county government maintains regular community gatherings through planning sessions, zoning meetings, and public forums at the Administration Center in Hillsboro.
Residents can process tax payments, obtain permits, and access property records through the official website or at the Administration Center on Maple Street.
