Ireland's Rent Pressure Zone Reform and Student Accommodation: What Changed

From Designated Zones to a National System

Ireland introduced Rent Pressure Zones (RPZs) in 2016 to slow rent growth in areas with high demand and rising prices. Inside a designated RPZ, a landlord could raise rent on an existing tenancy only by a capped amount, reviewed periodically by the government. Areas outside an RPZ had no such cap.

This created uneven protection: a student renting in Dublin or Cork, both RPZs for years, had a capped increase, while a student in a town never designated as an RPZ had none. Ireland reformed this system, and the Residential Tenancies Board confirms new rental law changes took effect nationwide from March 1, 2026, replacing the zone-by-zone approach. The reform followed years of debate about gaps in the old system that let rent reset between tenancies in some cases.

The new national rent cap in detail

From March 1, 2026, rent on a private tenancy can rise by at most 2% a year or the rate of inflation, whichever is lower, measured using the Consumer Price Index (CPI), according to the Residential Tenancies Board . This single rule now applies across the country, replacing the old system where the cap only existed inside a designated RPZ and rent outside those zones had no ceiling at all.

The cap covers both private tenancies and Student Specific Accommodation (SSA), so purpose-built student housing sits under the same national rule rather than a separate set of rules. Approved Housing Body and cost rental properties fall outside this cap and follow different arrangements.

Protection depends on when your tenancy started. For any tenancy that existed before March 1, 2026, a landlord cannot reset the rent to market rate between lettings. For tenancies starting on or after March 1, 2026, a landlord can reset to market rent only at the start of a new lease or after a tenancy runs for 6 years, with limited exceptions for no-fault terminations. Newly built apartments where construction started after June 10, 2025 follow inflation-only increases, without the 2% ceiling.

What This Means for Student Renters

Rent Pressure Zones mattered directly for students because most university towns, including Dublin, Cork, Galway, Limerick and Maynooth, were designated zones for years before this reform. A national system removes the question of whether your specific town or postal district counted as an RPZ, since the same underlying rules now apply across the country.

The reform confirms that Student Specific Accommodation falls under the same cap as other private tenancies, closing one of the open questions from when the change first rolled out. Confirm the current rules and calculator directly through the RTB before signing a new lease, and keep a record of the previous rent for any unit you view, since the allowed increase is calculated from that figure rather than from a fresh market estimate.

Steps Before You Sign

• Check the RTB website for the current national rent rules and calculator before you view a property.

• Ask the landlord or letting agent for the previous registered rent on the tenancy, since the 2% or CPI cap applies to that figure, not to a new asking price.

• Confirm whether your accommodation counts as Student Specific Accommodation or a standard private tenancy, since both now sit under the same national cap but can differ in lease structure.

• Ask when the tenancy started relative to March 1, 2026, since tenancies that began earlier keep stronger protection against a reset to market rent.

• Register your tenancy with the RTB once you sign, since this protects your rights under the system.
