Rent review evidence pack
Enter your details below. The tool works out an illustrative cap under the standard rule of national rent control (an annual increase of 2% or CPI, whichever is lower) and generates a printable one-page evidence pack with the RTB average rent for your town as background.
Not legal advice. Data sourced from the RTB and CSO. Results are illustrative; the RTB Rent Calculator is the official tool.
No figure for this tenancy type
New apartments and student accommodation whose construction commenced from 10 June 2025 follow CPI with no 2% cap. This tool holds no CPI series, so it prints no figure rather than a wrong one. Use the official RTB Rent Calculator, which applies the CPI figure for your review date, and read the RTB's guide to setting and reviewing rents from 1 March 2026.

Illustrative cap under the standard rule (2% leg)
| Rule | For a standard tenancy, rent may rise once a year by 2% or CPI, whichever is lower (Residential Tenancies (Amendment) Act 2025, national rent control from 1 March 2026). This pack computes the 2% leg only. Source: rtb.ie |

If CPI for your review period is below 2%, the lawful ceiling is lower than the figure above. The RTB Rent Calculator applies the CPI figure and is the authority; check it before relying on this pack.

These are the RTB's published average monthly rents for the town and quarter shown. The RTB does not publish the number of tenancies behind each average. Town averages are background only: the comparables the law requires are three similar dwellings in a similar area, which this pack does not supply.
What else the law says
- A rent review needs at least 90 days' written notice on the RTB's Notice of Rent Review form, and no more than one review in any 12 months.
- A market re-set (setting the rent afresh rather than by the cap) is allowed on a new tenancy after the previous tenant left by choice; once every 6 years at the end of a Tenancy of Minimum Duration cycle for tenancies created from 1 March 2026; and every 3 years from 1 March 2029 for student accommodation.
- Rent Pressure Zones, and the RPZ calculator that went with them, were replaced by national rent control on 1 March 2026. Every private tenancy in the State is now covered by the rule above.
- Official tools: the RTB Rent Calculator and the RTB guide to setting and reviewing rents from 1 March 2026.
