How to set your rent in Ireland in 2026 (RPZ rules + what's smart)

Pricing a rental in Ireland has two parts: what's legal, and what's smart. Most landlords focus on the first and ignore the second, which is why we see so many listings sit empty at 5% above market for six weeks instead of letting in 10 days.

Here's both.

Part 1: What's legal

Rent Pressure Zones (RPZ)

Since 2016, much of Ireland's rental market is in a Rent Pressure Zone. As of 2026 this covers nearly all of Dublin, Cork city, Galway city, Limerick city, Waterford, Drogheda, Bray, Maynooth, Naas, and most of the Dublin commuter belt. You can check whether your specific property is in an RPZ using the RTB postcode lookup.

If you're in an RPZ, rent increases are capped at the lower of 2% per year or the rate of inflation (the cap was tightened in 2024 from the previous 2% flat). The cap applies to existing tenancies and to new tenancies in properties that have been rented within the previous two years.

If you're not in an RPZ, you can set the rent freely, but you still need to give notice and you're still constrained by the next rule.

The "previous tenant" rule (this is where landlords get caught)

Even in non-RPZ areas, if your property was rented within the last two years, you cannot set the new rent higher than what the previous tenant paid plus the allowable increase. The two-year window resets every time you complete a tenancy.

In practice this means: if your last tenant paid €1,800/month and they moved out 18 months ago, you can advertise at most €1,800 × (1 + 2%) per year for two years = roughly €1,873/month. Not €2,100 just because the market has moved.

Overcharging here is now a criminal offence under the Residential Tenancies (Amendment) Act 2024. The RTB has been active in enforcement. Tenants can (and do) check rents against RTB records and report violations.
