Under the Planning and Development Act 2000, as amended, all development, unless specifically exempted under the Act or associated Regulations, requires planning permission.
In this regard, Class 31 of Schedule 2 of the Planning and Development Regulations 2001, as amended, provides that certain classes of development carried out by a statutory undertaker authorised to provide a telecommunications service are, subject to specified conditions, exempted development from the requirement to obtain planning permission. Where the conditions and size thresholds specified in the exemption class are not complied with or are exceeded, planning permission is required. This Class 31 exemption makes no distinction between the various generations of wireless mobile telecommunications technology.
These arrangements are considered appropriate for the purpose of supporting the roll-out of a high quality communications service while also taking account of the ongoing technological advances in this area. The legislative provisions are supplemented by planning guidelines entitled the Telecommunications Antennae and Support Structure Guidelines, which originally issued to planning authorities in 1996 and were revised in 2012, and which are available on my Department's website at the following link: https://www.housing.gov.ie/sites/default/files/migrated-files/en/Publications/DevelopmentandHousing/Planning/FileDownLoad%2C31650%2Cen.pdf.
