The Residential Tenancies Act 2004 regulates the tenant-landlord relationship in the private rented residential sector and the Act provides that landlords in the sector must apply to register the tenancy of a dwelling with the Private Residential Tenancies Board (PRTB), an independent statutory body established under the Act. The PRTB publishes a range of statistics, including tenancy registrations, in its Annual Reports which are available on the PRTB's website www.prtb.ie and the most recent report relates to 2010. Copies of the Annual Reports are also available in the Oireachtas library.
