My Department does not hold or collate the information referred to in the Question.
The Residential Tenancies Board (RTB) which was established as an independent statutory body under the Residential Tenancies Acts 2004-2019, operates a national tenancy registration system.
The Clerk of the Dáil requested that arrangements be put in place to facilitate the provision of information by State Bodies to members of the Oireachtas. Following the issue of Circular LG (P)05/16 on 20 September 2016 from my Department, the RTB set up a dedicated email address for this purpose. The RTB may be contacted at OireachtasMembersQueries@rtb.ie to establish the extent to which it may hold the information sought.
