What are Rent Pressure Zones?

A Rent Pressure Zone (RPZ) is a designated area where rents cannot be increased by more than general inflation, as recorded by the Harmonised Index of the Consumer Price (HICP). Any rent increase in a RPZ can not exceed general inflation, as recorded by Harmonised Index of the Consumer Price (HICP) and the rent previously set, cannot increase by more than 2% per year pro rata, where HICP inflation is higher. This applies to new and existing tenancies (unless an exemption is being applied). 

Rent Pressure Zones are located in parts of the country where rents are highest and rising, and where households have the greatest difficulty finding affordable accommodation. They are intended to moderate the rise in rents in these areas and create a stable and sustainable rental market that allows landlord and tenants to plan financially for their future.

What criteria must an area meet to be designated as a Rent Pressure Zone?

For an area to be designated a Rent Pressure Zone, the following criteria is used: 

  • The standardised average rent in the previous quarter must be above the appropriate reference standardised average rent in the quarter; and 
  • The annual rate of rent inflation in the area must have been 7% or more in four of the last six quarters. 

There are three different standardised average rents (see below), which to use depends on the location of the area being assessed:  

  1. Dublin: The standardised average rent in Dublin is now compared to the National Standardised Average Rent for the propose of RPZ designation. All of Dublin is currently designated as an RPZ. 
  2. GDA: The standardised average rent for LEA’s in the GDA (Meath, Kildare and Wicklow, excluding Dublin) is now compared to the Non-Dublin Standardised Average Rent for the purposes of designating an LEA as an RPZ. The Non-Dublin standardised average rent refers to the standardised average rent in the country, when Dublin is excluded. 
  3. Rest of Country: The standardised average rent for LEA’s in the rest of the country is now compared to the Rest of Country Standardised Average Rent for the purposes of designating an LEA as an RPZ. The Rest of Country standardised average rent refers to the standardised average rent in the country, when Dublin and the GDA are excluded. 

Exemptions to the Rent Pressure Zone rental cap

It is important to remember that not all properties in Rent Pressure Zones are subject to the HICP inflation restrictions. Exempt properties include properties that have not been rented for a period of two years prior to the immediate tenancy commencement date, a new tenancy in a protected structure that has not been let out in the previous 12 months and those properties that have undergone a 'substantial change in the nature of the accommodation'.  Please see bellow for further information on Exemptions to the Rent Pressure Zone rental cap.
