For most private tenancies in Waterford, rent increases are generally limited to the lower of 2% or the annual rate of inflation, and usually only once every 12 months. The landlord must give the required written notice, normally at least 90 days, and follow the prescribed calculation and notice rules. Different provisions can apply when setting rent for a new tenancy or where a statutory exemption applies. Check the RTB’s current rent calculator and guidance, as the RTB’s dispute resolution process or a solicitor would assess any disagreement based on the tenancy’s facts.
