Yes, Cork is covered by Rent Pressure Zone (RPZ) rules, although the exact position can depend on the property’s address and the tenancy’s circumstances. Before increasing rent, a landlord must follow the applicable legal limits, notice requirements and exemption rules. These rules can differ for newer tenancies or substantially renovated properties, so check the RTB’s official RPZ calculator and current guidance. If you believe an increase is unlawful, the RTB dispute resolution process can consider the individual facts, or you can seek advice from a qualified housing adviser or solicitor.
