Dún Laoghaire-Rathdown County Council is a Local Authority serving a population of approximately 233,000 people. We are one of three local authorities that succeeded the former Dublin County Council on its abolition in 1994 and our responsibilities include housing, community, roads and transportation urban planning and development, amenities, culture and environment in Dún Laoghaire-Rathdown county.

Our county administration is headed by Frank Curran, Chief Executive, and has offices at Dún Laoghaire and Dundrum. Dún Laoghaire-Rathdown County Council has 40 elected members.


Our Vision

The vision for Dún Laoghaire-Rathdown is to embrace inclusiveness, champion quality of life through healthy placemaking, grow and attract a diverse innovative economy and deliver this in a manner that enhances our environment for future generations.


The Council of the electoral County of Dún Laoghaire-Rathdown was established in 1985 with 28 members. Its members also sat as members of Dublin County Council and members from three electoral areas were also the members of Dún Laoghaire Corporation.

On 1 January 1994, under the Local Government (Dublin) Act 1993, County Dublin and the Borough of Dún Laoghaire ceased to exist with the new county of Dún Laoghaire-Rathdown succeeding in the area of the electoral county. Dublin County Council and Dún Laoghaire Corporation also ceased to exist and Dún Laoghaire-Rathdown County Council came into being.

The two sides of the county have distinct histories in terms of local government structures. On the Dún Laoghaire side of the county, the Borough of Dún Laoghaire had been established by the Local Government (Dublin) Act 1930 as a successor body to urban districts of Dún Laoghaire, Blackrock, Dalkey, and Killiney and Ballybrack. A Board of Town Commissioners for Kingstown had been established in 1834 and was subsequently renamed the Kingstown Urban District Council and then Dún Laoghaire Urban District Council. On the Rathdown side of the county, Rathdown No. 1 Rural District Council was established under the Local Government (Ireland) Act 1898. Rathdown No. 1 Rural District Council was abolished by the Local Government (Dublin) Act 1930.

On its formation, the Town Hall in Dún Laoghaire became the headquarters of Dún Laoghaire-Rathdown County Council. It was subsequently renamed County Hall.

The Local Government Act 2001 reformed the two-tier structure of local government. It confirmed the size of the council as 28 members. Under the Local Government Reform Act 2014, the size of the council was increased to 40 members as part of a nationwide reallocation of local authority membership numbers.
