Rent Increase and Tenant Rights in Ireland

Health, Safety & Fire Regulations published July 05, 2025

For renters in Ireland, understanding your rights regarding rent increases is essential. The Residential Tenancies Act 2004 provides a framework for how landlords can raise rent and the conditions under which this can occur. This article offers insight into these regulations and practical steps you can take if you face a rent increase.

Understanding Rent Increase Regulations

In Ireland, rent increases must be fair and abide by the rules set forth in the Residential Tenancies Act 2004. In essence, landlords can only increase rent once every 12 months, and they must give tenants at least 90 days’ written notice.

Exceptions and Regulations

  • Rent Pressure Zones (RPZs): These are areas where rents are highest and rising quickly. Rent increases within these zones are capped and can only increase by up to 2% per annum.
  • New Tenancies: For new tenancies, the rent set must not exceed the local market rent for similar properties.

Receiving a Rent Increase Notice

When you receive a rent increase notice, ensure it complies with legal requirements:

  • The notice must be in writing and include the date from which the new rent applies.
  • Details of any comparative rents used to justify the increase must be included.
Tip: If you receive a notice that doesn't meet these guidelines, you have the right to challenge it.

Challenging a Rent Increase

If you believe a rent increase is unjustified, you can take the following steps:

  1. Review the Notice: Check if the notice complies with the required legal standards.
  2. Respond in Writing: Send a written objection to your landlord within the stipulated timeframe.
  3. Apply to the RTB: If unresolved, you may submit a dispute application to the Residential Tenancies Board (RTB).

You can use the RTB's dispute resolution services to address these issues formally.
