IrelandMy landlord wants to increase the rent. Are there limits?
Yes, rent increases in Ireland are limited by law — they can only happen once every 24 months and must be reasonable, with notice given at least 90 days in advance.
What the Law Says
The Residential Tenancies Act 2004 sets clear limits on how and when a landlord can increase rent for private residential tenancies in Ireland.
Under the Act, a landlord may not increase the rent more than once every 24 months. This rule applies to all tenancies covered by the Residential Tenancies Board (RTB), including most private rented homes.
The landlord must give the tenant written notice of the proposed increase at least 90 days before it takes effect. The increase itself must also be 'reasonable' — meaning it should reflect current market rates for similar properties in the area.
These protections apply regardless of whether the tenancy is fixed-term or periodic (month-to-month), as long as it falls under the RTB’s remit.
Statutory TextA landlord shall not increase the rent payable under a tenancy more than once in any period of 24 months.
— Residential Tenancies Act 2004, s. 19 — Rent increases
What to Do
Check your tenancy start date and last rent increase date — ensure at least 24 months have passed.
Confirm you received written notice at least 90 days before the new rent is due.
Compare the proposed rent with similar properties in your area to assess if it’s reasonable.
If the increase breaks these rules, contact the Residential Tenancies Board (RTB) for advice or to make a complaint.
