Before 1925, the chair of each rural district council sat as an ex officio member of the council.[5] Under the Local Government Act 1925, rural district councils in Ireland were abolished and their functions transferred to the county councils.[6] In County Carlow, these were the districts of Baltinglass No. 2, Carlow and Idrone.[7] The number of members of the county council increased from 20 to 26.[8][9][10]
In 1942, in an order under the Local Government Act 1941, the number of councillors was reduced to 21.[11][12] This figure was restated by the Local Government Act 2001.[13]
In November 2012, Phil Hogan, the Minister for the Environment, Community and Local Government, appointed a Local Electoral Area Boundary Committee to review the allocation of seats and the local electoral areas across local authorities. In the case of Carlow County Council, it recommended a decrease to 18 seats.[14] This was implemented by the Local Government Reform Act 2014.[15] In addition, all town councils in Ireland were abolished and their functions transferred to the county councils. In County Carlow, these were the town councils of Carlow and Muinebheag.[16]
The council originally met in Carlow Courthouse.[17] The council established their County Secretary's Office at 1 Athy Road in the former offices and printing works of the Carlow Sentinel which ceased publication after the First World War.[18][19] The council subsequently moved further north along Athy Road into modern premises which are now known as the County Buildings.[20]
