RPZ Calculator - Residential Tenancies Board

Rent Pressure Zone calculator

Use the Rent Pressure Zone (RPZ) calculator to find out the maximum rent increase allowed for properties in Rent Pressure Zones.

All private tenancies and student-specific accommodation tenancies and licences in Ireland now come under Rent Pressure Zone rules.

Use the Rent Pressure Zone (RPZ) calculator to find out the maximum rent increase allowed for a tenancy. Landlords must check that a rent review is allowed for the dates they enter.

Reviewing rent in a new RPZ area

In an area that becomes an RPZ, the first rent review for a tenancy that existed in that area before it became an RPZ, can only take place two years after the last rent setting. That rent setting could be the date the tenancy started or the date of the last rent review. After your first rent review in an RPZ, you can review rent once every 12 months.

    Information


    The RTB is required by law to establish and maintain a RPZ calculator and publish a table of HICP values to assist both landlords and tenants understand how to lawfully set rents in a RPZ. The calculator will identify the percentage difference (if any) between the HICP value on the date the rent was previously set and the HICP value that applies on the date the new rent is set.

    Any rent increase in a RPZ is prohibited from exceeding general inflation (as recorded by the HICP inflation rate) and cannot increase by more than 2% per annum pro rata, where HICP inflation is higher. Rent may not be set above any permissible increase set out on the RPZ calculator.

    The cap of 2% per annum pro rata will result in lower rent increases in RPZs during times of high inflation. The calculator may indicate that no rent increase is allowed.

    There is no legal requirement on a landlord to increase the current rent amount. There is no legal obstacle to a landlord reducing the current rent amount.
