Does rent control exist in Ireland in 2026?

For many private tenancies, annual rent increases are capped at the lower of roughly 2% or inflation under the post-March 2026 framework the RTB publishes. New tenancies created from that date often sit under tenancy-of-minimum-duration rules that strengthen the right to stay beyond a simple one-year paper term. Exact notices, exemptions and transitional cases still live on the RTB site, so check the live pages before you argue with a landlord WhatsApp message: Rental contracts and deposits.

Landlords must still register tenancies with the RTB. An unregistered tenancy weakens everyone’s paperwork trail. Starting rent on a vacant unit can still feel high in Dublin even when future increases are capped: Rent in Ireland and How expensive is Ireland.

Short-term tourist lets and some licence arrangements sit outside ordinary RTB tenancy rules; do not assume every booking inherits rent control: Short-term housing and Avoid rental scams.
