There were no wards until 1876 when the council was divided into three wards: Chatsworth Ward to the north, Middle Harbour Ward to the east and Lane Cove Ward to the west. Lane Cove Ward subsequently became the separate "Borough of Lane Cove" on 11 February 1895. With the passing of the Local Government Act, 1906, the name was changed to be the "Municipality of Lane Cove" and with the passing of the Local Government Act, 1993, the council legally changed to "Lane Cove Council" and aldermen were retitled councillors.
