The deposit is capped at one month's rent, and since June 2025 rent increases are limited to 2% a year, or the HICP inflation rate if lower, as the whole of Ireland is a Rent Pressure Zone.
A written lease is compulsory and must be registered with the Residential Tenancies Board, which you can check on rtb.ie. Pay the deposit by bank transfer or insist on a signed, dated receipt. After six months of continuous occupation, you gain security of tenure.
