Limerick was designated as a Rent Pressure Zone under the previous rent-control system. However, from 1 March 2026, the RPZ system was replaced by national rules applying to residential tenancies across Ireland, so Limerick’s RPZ status is no longer the main test. Rent increases are generally limited by the national rules, subject to the tenancy’s circumstances and applicable exemptions. Check the latest guidance from the RTB or gov.ie, as the legality of a particular increase ultimately depends on the individual tenancy and the relevant rules.
