Waterford is covered by Ireland’s rent pressure zone rules. In general, a landlord can review the rent only once every 12 months, with an increase limited to the lower of 2% or the rate of inflation measured by the Consumer Price Index (CPI). Specific rules and exemptions can apply, including when setting rent for a new tenancy or after substantial changes to the property. Your landlord must also follow the required notice and documentation rules, and the RTB ultimately decides any dispute based on the tenancy’s facts. Check the latest RTB guidance or speak to a solicitor if you are unsure.
