, or county legislature. In some counties, there is a county mayor or a county executive. The position of mayor is mostly ceremonial in some states, while in others, the mayor is more powerful than the commissioners or supervisors.

In many states, the board in charge of a county holds powers that transcend all three traditional branches of government. It has the legislative power to enact ordinances for the county; it has the executive power to oversee the executive operations of county government; and it has quasi-judicial power with regard to certain limited matters (like hearing appeals from the planning commission if one exists).

As for the day-to-day operations of the county government, they are sometimes overseen by a county manager or chief administrative officer who reports to the board, the mayor, or both.

In some states, the county technically has a plural executive in that several important officials are elected separately from the board of commissioners or supervisors (implying they cannot be fired by the board). This can create tension if such officials then disagree on how to best carry out their respective functions.

Scope of power

The power of county governments varies widely from state to state, as does the relationship between counties and incorporated cities. The government of the county usually resides in a municipality called the county seat

, counties are now only geographic designations, and they do not have any governmental powers. All government is either done at the state level or at the municipal (city, town, or village) level. In Connecticut, 15 regional councils have been established to partially fill the void left behind when the state abolished its eight county governments in 1960. Connecticut's regional councils do not conform to the old county lines, but rather, they are composed of towns that share the same geographic region and have similar demographics. The regional councils' authority is much more limited compared with a county government: the regional councils have no taxing authority or authority to issue permits; the aforementioned powers are delegated to the town governments. However, the regional councils do have authority over infrastructure and land use planning, distribution of state and federal funds for infrastructure projects, emergency preparedness, and limited law enforcement duties.
