Louth is not treated as one county-wide Rent Pressure Zone: historically, designated areas included the Dundalk-Carlingford and Drogheda local electoral areas, so the exact property address matters. Rent rules changed nationally from 1 March 2026, replacing the previous RPZ-based system with national limits on rent increases in many private tenancies. Check the RTB’s current guidance and the relevant tenancy start date before relying on the older RPZ map. For a dispute or unusual tenancy arrangement, consider getting advice from a qualified solicitor or housing adviser.
