County Meath was designated as a Rent Pressure Zone under the previous system, although RPZ rules applied according to the relevant designation and tenancy circumstances. From 1 March 2026, national rent-control rules replaced the former RPZ framework, so rent-increase limits generally apply across Ireland rather than only in designated areas. The exact limit can depend on when the tenancy began, whether it is a new tenancy and any statutory exception. Check the latest guidance on gov.ie or the RTB website, or seek advice from a solicitor if your situation is disputed.
