President Michael D Higgins has signed into law a bill banning residential evictions from next month until the end of March.
It will mean that if a tenant is issued with an eviction notice from next month to the end of March 2023, it cannot be implemented until April.
However there will be exceptions for those who do not pay their rent or damage a property.
Speaking last week, Taoiseach Micheál Martin said the ban was about getting the balance right and keeping a roof over those at risk of homelessness.
"We are coming into winter and that's the context. There had to be lot of issues ironed out, not least legal underpinning of this. That had to be worked out," Mr Martin said.
