Rent Increase Regulations for Irish Renters

Notices of Termination & Eviction published July 05, 2025

If you are renting in Ireland, understanding your rights concerning rent increases is crucial. The Residential Tenancies Act 2004 regulates how much and how often rent can be increased. Staying informed ensures that any increase complies with legal requirements, helping you manage your finances and housing security.

Understanding Rent Increases in Ireland

Under the Residential Tenancies Act 2004, landlords must adhere to specific guidelines when increasing rent.

Criteria for Rent Increases

  • Landlords can only increase rent once every 12 months, and tenants must be given at least 90 days' written notice.
  • The new rent must align with local market rates unless the property is in a Rent Pressure Zone (RPZ), where increases are capped at 2% annually or in line with inflation, whichever is lower.

It’s important to verify whether your property is within an RPZ to understand your maximum potential rent increase. For a detailed list of current RPZs, visit the official government site.

Actions Renters Can Take

If You Receive a Rent Increase Notice

  • Verify the increase complies with RPZ regulations and the 12-month rule.
  • Check that the notice was given at least 90 days before the increase takes effect.
  • If the increase seems unjustified, you can file a dispute with the Residential Tenancies Board (RTB).
Always keep a record of all landlord communications regarding rent notices and increases.
