In Ireland, the minimum landlord notice period depends on how long the tenancy has lasted: 28 days for less than six months, rising to 112 days where it has lasted more than four years. However, “without cause” is not always permitted, particularly for tenancies covered by newer termination restrictions, and a valid notice may need to state a specific legal ground. The notice must also meet formal requirements, including being in writing and correctly served. Check the RTB’s current guidance or speak to a solicitor, as the outcome of any dispute depends on the tenancy’s facts.
