Kilkenny City was designated as a Rent Pressure Zone, but that designation did not automatically cover every property in County Kilkenny. From 1 March 2026, the former Rent Pressure Zone system was replaced by national rent-control rules for covered tenancies, so Kilkenny properties are generally assessed under the national rules rather than a separate RPZ designation. The detail can depend on the tenancy and the date of any proposed increase. Check the latest guidance from the RTB or gov.ie for the rules applying to your situation.
