Understanding Rent Increases and Your Rights

Dispute Resolution & RTB Hearings published July 05, 2025

Rent increases can be a daunting and confusing part of renting a property in the Republic of Ireland. Understanding your rights, as a renter, is crucial to ensuring that any changes in rent are fair and legal. In this guide, we'll look at key aspects of the process, highlighting useful steps and resources available to you.

Your Rights Under Irish Law

The Residential Tenancies Act 2004 (as amended) sets clear guidelines for rent hikes, aiming to protect tenants from sudden or excessive demands. This legislation, alongside the Housing (Standards for Rented Houses) Regulations 2019, ensures landlords follow a standardized procedure.

When Can a Landlord Increase Rent?

According to the Residential Tenancies Board (RTB), rent increases are permitted only after a certain period under specific conditions:

  • No increase is permitted within the first 12 months of the tenancy.
  • Subsequent increases can occur only once every 12 months.
  • The landlord must provide at least 90 days' written notice.

Notice of Rent Increase

Landlords must issue a formal notice to tenants, which is compliant with legal standards. This notice should specify the new rent amount and provide a rationale for the increase. Tenants should receive this notice 90 days before the new rent becomes due.

Challenging an Unjust Rent Increase

If you believe a rent increase is unjust, you can contest it through the RTB. Tenants are encouraged to gather evidence to present a strong case, including details of similar properties in the area.

Consider negotiating with your landlord if you feel an increase is unjust. Open communication can often lead to a mutually beneficial arrangement.

FAQs on Rent Increases

  1. Can my rent increase if I'm in a fixed-term lease? Unless mutually agreed, rent increases during a fixed-term lease are typically not allowed unless specified otherwise in the lease agreement.
  2. Is my landlord required to reduce the rent after a market drop? Currently, there is no legal obligation for landlords to reduce rent; however, tenants may discuss and negotiate any changes directly with the landlord.
  3. How is the market rent determined? Market rent is assessed based on rental prices for similar properties within a specific area. The RTB provides a rent index for reference purposes.
