A Dublin MEP has slammed the four local authorities for their lack of urgency in responding to the housing crisis.
Fine Gael politician Brian Hayes revealed figures showing that there has only been an output of 683 social houses in 2015 - with one constituency providing none in the last 10 months.
This figure is in contrast to the almost 45,000 people on the social housing list, with the number expected to rise in the coming months.
According to the information provided by Mr Hayes, South Dublin County Council has built no social housing units in 2015, despite having a waiting list of 8,780.
However, 805 are planned across the four authorities over the next two years, with a further 5,431 waiting on approval.
Hayes has said that Dublin local authorities need to up their game when it comes to providing housing across the capital.
"The crisis in social housing in Dublin continues to rumble on. There are now almost 45,000 people on the housing waiting lists in the Dublin area.
"That is an increase of more than 12,000 in the last two years," he said.
"Dun Laoghaire-Rathdown County Council has seen the biggest increase, with 60pc during that period.
"There needs to be a much more urgent response to the housing crisis by the four Dublin local authorities. In Dun Laoghaire-Rathdown County Council, for example, they have a waiting list of 5,500, yet they are planning to build just 12 social housing units in 2015.
"This is a totally inadequate response to the scale of the demand for social housing."
Dublin City Council has the most people on the housing list with 21,592, followed by Fingal County Council with 9,000.
Mr Hayes also called for a "close partnership" to help tackle the crisis, adding that over €300m had recently been announced to address the issue.
"An effective response will involve a close partnership between local authorities, national government, national agencies and voluntary organisations," he said.
"The Government have put the funds in place to support this. An additional €312m was also announced last week in the Capital Plan for this issue."
