The Simon Community say increasing rent supplement is the only way to help people stay in their homes.
It’s after they carried out a survey which showed that at the end of November, only one house was available in Dublin within welfare limits.
The survey looked at how many houses and apartments were available to let over a three day period and the cost of the rent.
During the snapshot period in November, 245 places were available in Dublin but only one of them fell within the limits
Spokesperson Niamh Randall says the only way to change it is increase the welfare payment:
"The rent supplement levels and the HAP levels are the same. They were set in June 2013. What we know is that market rents have increased by 20 percent since then even more in some areas. So there's a massive gap there".
Niamh added there are some schemes in place in the Dublin area:
"There is a tenancy protection service where discretion is applied, where people's rent is increased and where rent supplement amounts have been increased. There's also what's known as the homeless specific HAP pilot where rents in Dublin can be increased by 50 percent".
The survey comes ahead of an announcement by the Environment Minister Alan Kelly of funding to build an extra 1000 social houses.
