You generally need to give written notice for the correct notice period, which depends on how long you have lived in the property; check your tenancy agreement and the RTB’s guidance. Before leaving, pay rent and bills, remove your belongings, clean the property, record meter readings, take dated photographs and return all keys. Your landlord should account for any proposed deposit deductions, which may relate to unpaid rent, bills or damage beyond normal wear and tear, but the outcome can depend on the tenancy’s facts. If you cannot resolve a dispute, you can consider the RTB’s dispute resolution process or seek advice from a solicitor.
