No, being in a Rent Pressure Zone does not by itself give a landlord a right to end your tenancy or avoid the applicable rent-increase rules. A landlord must rely on a lawful ground for ending the tenancy, follow the required notice procedures and, where relevant, provide supporting declarations or other documents. If the stated reason is not genuine and the real purpose appears to be replacing you with a higher-paying tenant, you may be able to bring a dispute to the RTB. The outcome would depend on the individual facts, so consider getting advice from Threshold or a solicitor and check the current rules on the official gov.ie website.
