Deltona operates under a commission–manager form of government, consisting of seven elected officials, and an appointed city manager. Residents elect, through non-partisan elections, a mayor who represents the city at-large and six commission members who each represent a specific district of the community. Elected officials serve four-year terms, with a limit of two successive four-year terms. The mayor serves as the presiding officer at official meetings and as the ceremonial head of the city. A vice mayor is elected annually by the city commission from among the commission members. The current mayor is Heidi Herzberg, who was elected into office in November 2018.
