Tenancy Types & Agreements published July 05, 2025

As a renter in Ireland, understanding your rights regarding rent increases is crucial for maintaining a stable and affordable living situation. Rent increases can be stressful, but knowing the regulations set by the Residential Tenancies Act 2004 helps in navigating these challenges.

Understanding Rent Increases

Under the Residential Tenancies Act 2004, landlords in Ireland must adhere to specific rules when increasing rent. This legislation has been amended to include protections for tenants, ensuring rent hikes are fair and justified.

When Rent Increases are Allowed

Landlords can increase rent in line with the Residential Tenancies Board (RTB) regulations. However, they must give tenants at least 90 days' notice before the increase applies.

  • Rent can be reviewed every 12 months or in accordance with local Rent Pressure Zone regulations.
  • Landlords must issue a detailed written notice with specific information about the increase.
Your landlord is required to provide a transparency of calculations if the rent is being increased in a Rent Pressure Zone.

How to Challenge an Unfair Rent Increase

If you believe a proposed rent increase is unfair, you can challenge it through the Residential Tenancies Board. Make sure to gather comprehensive evidence, including the notification details and comparable rents in your area.

Official Forms and Steps

Tenants can utilize specific forms to address issues related to rent increases. Here are the most relevant:

  • RTB1 Form: Use this form to register your dispute with the RTB if you believe a rent increase is unjust.
