First costs to budget for

Most private rentals require a deposit and rent in advance. You may also need temporary accommodation while searching, moving costs, bedding, utilities and transport. Keep proof of every payment and avoid paying large sums without a clear written agreement.

Proof of address

A lease or tenancy agreement can help you prove your Irish address for banking, PPS or other services. If you are staying with friends or family, some services may accept a letter from the bill holder plus their household bill, but each provider has its own rules.

RTB registration

Most private residential tenancies in Ireland must be registered with the Residential Tenancies Board by the landlord. Tenants can check the RTB public register to see whether a tenancy is registered.

Rent rules from 1 March 2026

RTB says a national system of rent control applies from 1 March 2026. For most private tenancies, rent can only be increased once every 12 months by 2% or the rate of inflation measured by the Consumer Price Index, whichever is lower.

RTB also says that re-setting to market rent is allowed only in specific cases for private tenancies created from 1 March 2026. For ongoing private tenancies created before that date, re-setting to market rent is not allowed while that tenancy continues. The rules can depend on tenancy dates, property type and how an earlier tenancy ended.

Rent Tax Credit

If a person rents privately and pays Irish income tax, Revenue's Rent Tax Credit rules may be relevant. Common records include details of the tenancy and rent paid. See the Rent Tax Credit guide for general information.

The rental market is under pressure. Upfront payments carry risk if the property has not been viewed or the person offering it has not been confirmed as legally able to rent it.
