Understanding Rental Increases in Ireland

Notices of Termination & Eviction published July 05, 2025

As a renter in Ireland, you might be concerned about possible rent hikes and your rights when they occur. It's essential to understand how rent increases are regulated under the Residential Tenancies Act 2004 and the steps you can take to protect yourself.

What Does the Residential Tenancies Act Say about Rent Increases?

The Residential Tenancies Act 2004 (as amended) provides that landlords can only increase rent once every 12 months, and the increase must not exceed the limits set by the Rent Pressure Zones (RPZs). The landlord is required to give you a notice in writing at least 90 days before the increase takes effect. This notice must detail how the proposed increase complies with the law.

Are You in a Rent Pressure Zone?

If you live in a Rent Pressure Zone, any rent increase is capped at a certain percentage according to the RPZ guidelines. The Residential Tenancies Board (RTB) provides a list of RPZs, updated regularly, and these areas have specific rules to prevent excessive rent increases.

What Should You Do If You Receive a Rent Increase Notice?

If you receive a rent increase notice, ensure it meets the legal requirements as outlined by the Residential Tenancies Act 2004. You should:

  • Verify that you’ve received at least 90 days' notice.
  • Check if your residence falls under a Rent Pressure Zone.
  • Ensure the increase abides within the RPZ limits, if applicable.
Tip: If you believe the notice is not compliant, you can challenge it with the RTB.

Filing a Challenge or Dispute with the RTB

Should you decide to dispute the rent increase, you can submit a dispute resolution application to the Residential Tenancies Board. Use the RTB Dispute Resolution Application Form available on their website. This service aims to mediate between tenants and landlords to find a resolution.

  1. When can a rent increase be challenged? You can challenge a rent increase if it does not comply with the notice period or exceeds the cap set by Rent Pressure Zones.
  2. What should a valid rent increase notice include? A valid notice should include the amount of the new rent, the effective date, and clarification on how the increase complies with the RPZ limits, if applicable.
  3. Where do I find details about Rent Pressure Zones? You can find updated information about Rent Pressure Zones on the RTB website, which lists all designated areas with caps on rent increases.
