There is no single official average rent increase for Waterford, as changes vary by property, tenancy and market conditions. For a tenancy covered by Rent Pressure Zone rules, a rent review is generally limited to once every 12 months, with the increase subject to the applicable legal cap, such as 2% or inflation if lower. Your landlord must provide the required rent review notice and supporting information. Check the current RTB guidance and rent calculator, as exemptions and rule changes may apply; any dispute is ultimately decided through the RTB process or by a solicitor.
