Understanding Rent Increase Rules for Irish Tenants

Notices of Termination & Eviction published July 05, 2025

As a renter in Ireland, knowing your rights regarding rent increases is essential to avoid unexpected financial challenges. The Residential Tenancies Act 2004, as amended, sets out clear guidelines for landlords on how rent can be increased, providing a framework for renters to ensure any changes to their rent are fair and justified.

How Rent Increases Work in Ireland

Under the Residential Tenancies Act 2004, rent increases can usually only occur once every 12 months in most tenancies. Landlords are required to provide tenants with proper notice, which is typically at least 90 days before the increase is set to take effect.

Conditions for Rent Increases

  • Tenants must receive a valid written notice.
  • The increase must correspond with local market rents for similar properties.
  • The notice should specify the amount of the new rent and the date it will apply.

For specific cases, such as properties in Rent Pressure Zones (RPZs), there are additional restrictions that often include caps on how much rent can be increased annually.

If you receive a rent increase notice, thoroughly check the validity of the notice and ensure it complies with the Residential Tenancies Act 2004 guidelines. If unsure, seek advice to understand your options.

Forms and Resources for Addressing Rent Increases

When facing a rent increase, here are some vital steps and resources:

  • Review the Notice: Ensure the notice meets the legal requirements. This includes verifying the notice period and any adjustments relevant to RPZs.
  • Dispute Resolution: If you believe the rent increase is unjustified, you can refer the matter to the Residential Tenancies Board (RTB) for dispute resolution.
  • RTB Dispute Application Form (RTB1): Use this form to initiate a dispute regarding a rent increase. You can download it from the RTB's official site here.
