Maximum parking rates for new residential developments are addressed at a national level in the sustainable residential development and compact settlement guidelines issued in 2024 under section 28 of the Planning and Development Act 2000. The specific planning policy requirement, SPPR 3, of the settlement guidelines sets out graduated maximum car parking rates based on proximity to urban centres and sustainable transport options. These range from one space per dwelling in central or accessible locations to two spaces per dwelling in more peripheral or intermediate locations with higher rates of car dependency.
While the settlement guidelines set out the general policy approach, where planning permission is sought for particular residential development proposals, planning authorities and An Coimisiún Pleanála will need to be satisfied that the necessary and appropriate provision of parking is provided in accordance with the requirements of the settlement guidelines. For developments of 100 residential units or more, the settlement guidelines recommend that a mobility management plan or travel plan is prepared in support of the proposed parking arrangements. These guidelines are designed to strike the balance between the need for residents to have access to parking and the need to encourage the use of other transport networks. In areas with strong public transport links, lower parking ratios may be appropriate. However, planning authorities must also ensure that parking provision is sufficient to meet the specific needs of future residents of a proposed development, taking into account the local context.
That being said, the provision of car parking can add significant cost to developments, particular the high-density schemes the Deputy referenced, such as apartments, where higher ratios of parking necessitate a podium or basement car park.
