The lifting of the eviction ban is a "horror movie" for all the tenants who have received notices to quit, according to a homeless charity.
The ban on no-fault evictions is set to be lifted at midnight.
Protests are planned over the weekend to highlight the potentially disastrous impact of the move on thousands of people in the rental sector.
Fr Peter McVerry says lifting the ban is an appalling decision.
''There is not one single homeless charity that supports the lifting of the eviction ban, every single charity has come out and said this is a disaster.''
