Limerick follows the national Irish tenancy rules, so the required notice period depends on how long the tenancy has lasted: 90 days for under six months, 152 days for six months to one year, 180 days for one to seven years, 196 days for seven to eight years, and 224 days for over eight years. A landlord generally must use the correct notice format, give a valid reason where required, and send a copy to the RTB within 28 days. Special procedures apply for rent arrears or serious breaches, and a landlord cannot lawfully remove you by changing the locks. The RTB or a solicitor can assess whether a particular notice is valid.
