The governing body members shall be residents and registered voters of the city, and the councilmembers from wards shall be actual residents of their respective wards at the time of their respective candidacies and elections. Removal of a councilmember from a ward to another ward within the municipality after his or her election, or a change in ward boundaries, shall not disqualify the councilmember from completing the term for which he or she was elected.
