The Government has been urged to introduce rent controls or increase rent allowance to stop driving tenants into homelessness.
Campaigner for the homeless, Fr Peter McVerry, said rent controls are necessary to ensure that the market retains an element of affordability.
New figures show the number of people sleeping rough on the streets of Dublin has trebled in the last five years.
Fr McVerry challenged the Government to outline just what it is going to do to tackle rising homelessness as we approach the coldest months of the year.
"A lot of people who are becoming homeless today and there are six new people becoming homeless every day, a lot of them are getting kicked out of their private rental accommodation because their rents are going up and they can't afford the increase," he said.
"if the Government are not going to introduce rent controls and if they're not going to increase the rent allowance to allow people to pay the increased rents, then what on Earth are they going to do?"
