Understanding Rent Increase Rules in Ireland

If you're renting a home in Ireland, understanding the rules around rent increases is crucial in ensuring that you're being charged a fair price and are protecting your rights under Irish law. The Residential Tenancies Act 2004 (as amended) lays out important rights and obligations for both tenants and landlords when it comes to changes in rent. Let's explore these regulations to help you feel secure and informed.

What Does the Law Say About Rent Increases?

The Residential Tenancies Act 2004, with its amendments, provides that rent can only be reviewed every 12 months in most cases. Additionally, landlords must give tenants ample notice before implementing an increase. According to the Residential Tenancies Act 2004, landlords must provide at least 90 days of advance notice.

How is the Rent Increase Calculated?

In Ireland, rent increases in Rent Pressure Zones (RPZs) are based on specific restrictions to prevent excessive hikes. The increase must not exceed the rate of inflation, as calculated by the Harmonised Index of Consumer Prices (HICP). You can check if your property is within an RPZ and ensure compliance by contacting the Residential Tenancies Board (RTB).

Outside RPZs, the new rent set by a landlord should not exceed market rent, which is the rent a willing tenant would pay and a willing landlord would accept on market conditions. Rent cannot exceed the going market rate for similar properties in the area.

Steps to Challenge a Rent Increase

If you believe a proposed rent increase is unjustified, take action promptly.
  1. Review the notice: Check if the notice of rent increase complies with legal requirements, including timing and amount.
  2. Respond in writing: Send your landlord a written objection stating your reasons for disputing the increase.
  3. Apply to the RTB: If the issue isn't resolved, you can lodge a formal dispute with the RTB using the RTB1 form, which is available on rtb.ie.
