If a property has never previously been rented, the landlord can generally set the starting rent at market rent, even if it is in a Rent Pressure Zone (RPZ). However, later rent reviews are normally subject to the RPZ rent-increase rules, unless a specific legal exception applies. The landlord should give the tenant the required rent-setting information, including comparable local rents where applicable, and register the tenancy with the RTB. As RPZ rules can change, check the latest guidance on gov.ie or ask a solicitor about the individual property and tenancy.
