Minimum standards for rented accommodation are prescribed in the Housing (Standards for Rented Houses) Regulations 2008 as amended, made under section 18 of the Housing (Miscellaneous Provisions) Act 1992. All landlords have a legal obligation to ensure that their rented properties comply with these regulations.
Responsibility for the enforcement of the regulations rests with each local authority. Information on enforcement on a local authority basis is compiled and made available as part of my Department's housing statistics publications. Data in respect of the years 2005 to 2013 can be accessed via the following link: http://www.environ.ie/en/Publications/StatisticsandRegularPublications/HousingStatistics/FileDownLoad,15293,en.xls.
The returns from local authorities in respect of 2014 are currently being compiled and validated prior to publication.
The regulations, with some exceptions, apply to all rented dwellings. My Department does not hold information on the compliance rate of dwellings where tenants are on rent supplement.
