Understanding and navigating rent increases can be challenging for renters in Ireland. With laws like the Residential Tenancies Act 2004 (as amended), renters need to be informed about their rights and options when facing rent hikes.

What You Need to Know About Rent Increases

  • The increase must align with market rents for similar properties in the area.

How to Respond to a Rent Increase

If you receive a notice of a rent increase, these steps can help you handle the situation effectively:

  1. Review the notice carefully. Ensure it fits the legal criteria established by the Residential Tenancies Act 2004.
  2. Gather evidence of local market rents for similar properties.
  3. Submit a written objection to your landlord if you believe the increase is unjustified.
  4. File a dispute resolution with the Residential Tenancies Board (RTB) if needed.
Make sure to keep all documentation and correspondence related to the rent increase.

Submitting a Dispute

To submit a dispute over a rent increase to the Residential Tenancies Board (RTB), use the RTB Dispute Application form. This process can support you in seeking a fair resolution.
