The RTB usually updates their Rent Pressure Zone (RPZ) Calculator in line with new legislation.
In the last update, rents can no longer increase by 2% per year. They are now linked general inflation (as measured by HICP Index in Ireland).
As a reminder, all new tenancies and Rent Reviews in an RPZ (e.g. Dublin) must use the calculator when establishing the new maximum rent permissible.

What are the new RTB rules for March 2026?
From 1 March 2026, all new tenancies will become tenancies of minimum duration (TMD). A tenancy of minimum duration will last for 6 years. It will then be renewed for another 6 years and will continue for 6-year cycles.
What properties are exempt from RTB?
Tenancies that don’t need to be registered
- Business rentals: properties used for business purposes.
- Holiday rentals: short-term lettings for holidays.
- Former rent-controlled properties or long-occupation lease tenancies: separate legislation applies to them and they are not covered by the Residential Tenancies Act.
How do we calculate rent?
- Weekly Rent ÷ 7 = Daily Rent amount.
- Daily Rent x 365 = Yearly Rent amount.
- Yearly Rent ÷ 12 = Monthly rent amount.
