The limit on rent increases in Glenageary
Since 1 March 2026 every private tenancy in Ireland is under the same rent control. A sitting tenant’s rent may be reviewed once in 12 months, and the increase may not exceed inflation since the rent was last set or 2% a year pro rata, whichever is lower. It may never go above market rent. Glenageary (Dún Laoghaire local electoral area, Dun Laoghaire-Rathdown County Council) was a Rent Pressure Zone from 24 December 2016, so a cap has applied here since then.
The average above is a market-wide figure. For one home the law looks at three similar homes let recently in the same area, and that is what a Notice of Rent Review or a Rent Setting Notice has to cite.

Questions
Is €2,805 the asking rent in Glenageary?
No. It is the average rent of tenancies that were newly registered with the Residential Tenancies Board in Q4 2025, as published by the CSO in the RTB Rent Index. Asking rents on listing sites are usually higher, because they include homes that did not let at that price and exclude the discounts agreed before signing.
Why is my rent so different from the average?
The average mixes every size, type and condition let in the quarter. A one-bed apartment and a four-bed house pull it in opposite directions. The tables above split it by bedrooms and by type; for one home, the three closest registered lettings matter more than any average, and that is what our reports look up.
How much can the rent go up in Glenageary?
Since 1 March 2026 the same limit applies everywhere in Ireland: once every 12 months, by no more than inflation since the rent was last set or 2% a year, whichever is lower, and never above market rent. Glenageary was already a Rent Pressure Zone from 24 December 2016, so the limit has applied here for longer. New apartments whose construction began on or after 10 June 2025 follow inflation only.
Where do these figures come from?
From the RTB Rent Index, table RIQ02 on the CSO's PxStat service, licensed CC BY 4.0. The RTB compiles it from tenancies registered with it, so it reflects rents actually agreed, not advertised. Figures are suppressed where too few tenancies were registered in a quarter, which is why some cells are blank.
