County commissioners enforce local laws, codes and ordinances. They oversee the sheriff’s department and allocate money within the budget for maintaining infrastructure and unincorporated areas. Some areas have both a council and a commission, while others incorporate the responsibilities of both roles into one position. Mayors are the head of a city and are generally part of the city council or commission. Some cities elect the mayor separately, while others have councilors appoint the mayor from the council on a rotating basis.
