A disagreement is emerging over the provision of social housing in the capital.
It comes as close to 1000 children were homeless in Dublin at the end of last month.
At the end March, 911 children and their families were in emergency accommodation in Dublin, having lost their homes, mostly in the private rental sector.
Rents rose by around 10% in the month while the Government ruled out increasing rent supplement.
And just last week, Dublin City Council rejected a plan to refurbish a block in O’Devaney Gardens to provide Emergency accommodation for homeless families.
Environment Minister Alan Kelly says he needs cooperation from the Council.
"They have to find alternatives. And my real concern is that we will be back here in another month's time talking about the fact that Dublin City Council opposed another two or three or four or five areas," said Minister Kelly.
"Dublin City Council and other councils need to work with me on that," said the Minister.

But Dublin’s Mayor Christy Burke says the whole project needs regeneration, not just one block.
"It's easy for the Minister to blame. The money is there so lets demolish the three blocks and lets develop," said Mayor Burke.
A meeting is scheduled to take place between both men in the near future.
