There is a legal obligation on landlords to register their tenancies with the Residential Tenancies Board (RTB). The RTB aims to ensure that all rented tenancies that fall within its jurisdiction are registered.


All tenancies should be registered with the RTB. Further information on how to register a tenancy can be found here. If the tenancy has not been registered within one month of the beginning of the tenancy a late fee will apply. 

Information on the fees that apply to a tenancy registration which is received late by the RTB is available here

What do I do if I have received a notice? 

Contact the Registration Enforcement section quoting the reference number on the received notice/solicitor's letter. The reference will begin with ‘RE’ and can be found at the top of the notice. 

To discuss the required actions that may be taken or if there is a query regarding non-compliance/ legal proceedings, contact the Registration Enforcements section of the RTB  on 0818-303038 (Monday to Friday 9am-5pm) or by email at 

If a tenancy is unregistered, an application to register a tenancy must be submitted on receipt of a Registration Enforcement notice. When a registration number is received, confirming the registration of the tenancy in question, Registration Enforcement should be contacted with this number to confirm registration and to stop legal proceedings. 

Report an unregistered tenancy 

If you would like to report a potential unregistered tenancy to the RTB, please email with a completed Registration Enforcement referral form which is available on the RTB here. Alternatively, you can leave a voicemail on 0818-303038 and a member of the Registration Enforcement team will be in contact. 

Penalties for not registering 

A person who does not comply with their responsibility to register their tenancy/ tenancies faces a criminal conviction and a fine of up to €4000 and/ or 6 months’ imprisonment, if convicted. In addition to the Court imposed fines, the landlord will also have to pay the RTB’s legal costs which can be in the region of €2,500 plus VAT per case. 

The RTB does not wish to prosecute landlords. We will work with landlords to assist them in registering their tenancies if they contact us on receipt of the formal notification and in advance of any summons issuing. However, if a summons has issued then the case will go to Court.

Search the register 

The addresses of all current active/live tenancies, registered with the RTB, can be found here. 

The RTB published register of tenancies contains a record of all current active/live tenancies registered with the RTB. It is updated weekly and does not include details of historic tenancies.

If you cannot find a tenancy in the published register, please try broadening your search to capture any possible variations of the address - For example, Apartment 1 may be listed as Apt. 1 or Flat 1. 

The published register does not contain information on previously registered tenancies. If you would like to know whether a tenancy was previously registered, please contact the RTB by email at: XXXXX. Once a tenancy has concluded, only the landlord or tenant of that tenancy may request information to check if the tenancy was registered

Notify the RTB of an unregistered tenancy 

The Rregistration Enforcement section can be contacted by email at or by phone on 0818-303038 (Mon-Fri 9.30am-5pm).
