The government's housing policy "simply isn't working", according to Sinn Féin.
The party is bringing a motion to the Dáil tonight calling for a housing emergency to be declared.
It follows reports of a government underspend of almost half a billion euro on social and affordable housing projects so far this year.
Sinn Féin's housing spokesperson, Eoin Ó Broin says the purpose of the motion is to put pressure on the housing minister to act now.
"We need an emergency ban on rent increases, and we need a real refundable tax credit that will put a month's rent back in every renter's pocket.
"In terms of homelessness, we need the government to double the number of housing first tenancies to start bringing down the unacceptably high level that single person homelessness.
"We need a much more aggressive attitude by government and councils to purchasing private rental properties with a HAP tenant in situ, that has a notice to quit."
