The main governance structure at the county level is typically the Commissioners Court. This body is made up of elected officials, including a county judge and commissioners, who have a wide range of administrative and executive powers within the county government. They are responsible for overseeing county operations, setting budgets, enacting ordinances, and making policy decisions for the county. The council-manager structure is also common in some counties, where an elected council hires a professional manager to oversee day-to-day operations.
