Understanding Rent Increases and Tenant Rights

Living in rented accommodation in the Republic of Ireland comes with distinct rights and responsibilities. As a tenant, understanding your rights concerning rent increases and the legal framework governing this process is crucial. This article explores your rights under the Residential Tenancies Act 2004 and offers guidance on steps to take if you face a rent increase that you believe is unjust.

Rent Increases: What Are Your Rights?

The Residential Tenancies Act 2004 (as amended) regulates rent increases in Ireland, ensuring they are fair and transparent. Under this act, landlords can only increase rent after 24 months have passed from the start of the tenancy or since the last increase. The landlord must provide written notice of any rent increase, which must include:

  • The amount of the new rent
  • The date from which the new rent is payable
  • The reasons for the rent increase

Additionally, this notice must be given a minimum of 90 days before the increase takes effect. For tenancies commencing after 24 December 2016, the maximum annual rent increase is capped at 4% if the property is located in a Rent Pressure Zone (RPZ).

Disputing a Rent Increase

If you believe your landlord has issued an unfair rent increase, you have the right to dispute it. Begin by discussing the matter directly with your landlord and attempting to reach a resolution. If an agreement cannot be made, you can file a dispute with the Residential Tenancies Board (RTB).

How to File a Dispute

When filing a dispute with the RTB, you will need to complete and submit a dispute application form, either online or by post. Ensure you include all relevant information and documentation concerning the rent increase. You can find the appropriate form and detailed guidance on the RTB's website.

Make sure to submit your dispute application within 28 days of receiving the notice. Late applications might not be accepted.
