Jurisdiction: Republic of Ireland

Mini Summary

The Planning and Development Act 2000 is designed to serve as a planning code and therefore, in order for any development to be valid it should be undertaken in compliance with the requirements of this legislation, as well as any other legislation such as the Environmental Protection Agency Act 1992.

The Planning and Development Act 2000 revised the entire amount of planning law into a single piece of legislation, covering all forms of planning and development. The scope of the Act is wide and sets out a detailed section-by-section analysis of the provisions of the Act, including development plans, local area plans, regional planning guidelines, architectural heritage, housing supply, appeal procedures and environmental impact assessment. Under the Act each Local Authority has a responsibility to determine policy in its area through a Development Plan and for applying the policy through planning control, planning applications and enforcing planning decisions.

The amendments of 2002 include changes to Part V of the 2000 Act (Housing Supply) and other miscellaneous amendments.


The following definitions in the Planning and Development Act 2000  are amended.

Large-scale residential development (LRD) means:

  • the development of 100 or more houses; and
