Understanding Rent Increase Rights for Tenants

As a renter in Ireland, staying informed about your rights regarding rent increases is crucial to ensuring you can effectively manage your tenancy. Understanding the laws governing rent increases and knowing your rights under the Residential Tenancies Act 2004 (as amended) can be empowering and help protect your interests.

Key Points About Rent Increases

Under the Residential Tenancies Act 2004, there are clear guidelines landlords must follow when increasing rent. These guidelines are designed to ensure that rent increases are fair and transparent.

  • Frequency of Increases: Landlords can increase rent once every 12 months in Rent Pressure Zones (RPZs) and once every 24 months outside of RPZs. [1]
  • Written Notice: Tenants must receive at least 90 days' written notice of the intended rent increase.
  • Market Rate: The new rent must not be above the local market rate for similar properties.

Steps to Challenge a Rent Increase

  • Check the Validity: Review the notice to ensure it complies with legal requirements.
  • Gather Evidence: Collect data on comparable rents in your area.
  • Contact the RTB: If you believe the increase is unfair, contact the Residential Tenancies Board (RTB).
  • File a Dispute: Use the RTB’s dispute resolution service to challenge the increase legally.

Understanding Rent Pressure Zones

Rent Pressure Zones (RPZs) are designated areas where rents are highest and rising the fastest. In these areas, annual rent increases are capped to prevent excessive charges on tenants.

Ensure your property is within an RPZ using the RTB's RPZ calculator.

Filing a Dispute with the RTB

If you believe a rent increase is unjust, you can file a dispute through the RTB to seek a resolution. The RTB is the official body for handling such disputes and offers a comprehensive process for addressing tenant and landlord issues.

  • Use the RTB’s Online Portal: Submissions can be completed online through the RTB’s portal.
  • Provide the Necessary Documentation: Include all relevant documentation, including the notice of rent increase and evidence of comparable market rents.
  • Await a Decision: The RTB will review the case and issue a decision.

    You must receive a minimum of 90 days' written notice of any rent increase.
