Understanding Rent Increase Rules in Ireland

Tenant Rights & Responsibilities published July 05, 2025

Rent increases can be a significant concern for tenants in Ireland, as they impact monthly budgets and living situations. Understanding the Residential Tenancies Act 2004 and related regulations is crucial to navigating potential changes.

What Are the Rules for Rent Increases?

In the Republic of Ireland, landlords must adhere to specific legal processes when increasing rent. These are outlined in the Residential Tenancies Act 2004.

  • Rent can only be reviewed once every 12 months.
  • Landlords must provide at least 90 days' notice.
  • Any increase must be in line with local market rates.

Rent Pressure Zones

Certain areas in Ireland are designated as Rent Pressure Zones (RPZs), where rent increases are capped. In these areas, landlords can only increase rent by up to 2% annually or in line with the Harmonised Index of Consumer Prices, whichever is lower. For a list of RPZs, visit the RTB's official website.

How to Challenge a Rent Increase

If you believe that a rent increase is unjust, you can challenge it through the RTB.

Steps to Challenge

  1. Review the Notice: Ensure the increase complies with legal requirements.
  2. Gather Evidence: Collect evidence of comparable rent for similar properties in your area.
  3. Submit a Dispute Resolution Request: Complete and submit the RTB Dispute Resolution Request Form.
Remember to always keep copies of all correspondence and documentation related to your tenancy.

If you are unsure, seeking advice from tenant advocacy groups can help simplify the process.
