A general law county is governed under general law in which the county board of commissioners shares executive and legislative functions with other county-wide elected and appointed officials. Most general law counties operate under a regular board of commissioners form of government in which the board shares executive functions with an elected county treasurer and clerk, but performs all other executive functions. But they may operate under a county administrator or a county controller form of government in which a county administrator or county controller carries out many of the day-to-day functions of the government. In either case, these appointed officials serve at the pleasure of the board. The differences between the county administrator and county controller form is that it requires a 2/3 majority to dismiss a controller but only a simple majority to dismiss an administrator. General law counties are the most numerous; 79 of the state's 83 counties are governed under the general law form with 61 choosing an administrator or a county controller option.
