Generally, no. A genuine short-term holiday letting is usually not a residential tenancy covered by the Residential Tenancies Act, so RPZ rent-increase rules do not normally apply. However, the label used in an agreement is not decisive: an arrangement described as a holiday let may be treated differently if the property is actually being used as someone’s home or the tenancy facts point to a residential letting. The RTB or a solicitor would assess the individual circumstances, so check the latest guidance on gov.ie or seek professional advice if the arrangement is unclear.
