No. In Ireland, a landlord generally must give at least 90 days’ notice of a rent increase, regardless of whether the tenancy has lasted months or many years. Rent reviews are normally limited to once every 12 months, and the increase must comply with the applicable rent-setting rules, including any Rent Pressure Zone or national limits. The landlord must also send the required rent review notice to the RTB; if the notice or increase is disputed, the RTB can decide the issue based on the tenancy’s facts.
