Irish tenancy rules are shaped mainly by the Residential Tenancies Acts, later legislation and court judgments, while published RTB determinations show how the rules have been applied to particular disputes. RTB decisions can be useful for issues such as valid notices of termination, rent increases, deposits and anti-social behaviour, but they do not automatically create binding precedent for every tenancy. You can search the RTB’s published determinations and check the current legislation on the official Government or RTB websites. The outcome of any dispute depends on its facts and is ultimately determined through the RTB process or, where relevant, by a court.
