The Minister for Housing, Darragh O'Brien, has said that the Government is committed to eradicating homelessness by 2030.
"We as a Government made a decision a couple of months ago," he told a press briefing following the launch of the new Housing For All strategy.
"I brought a memo to the Government in relation to the Lisbon Declaration, which asked all the EU member states to sign up to the eradication of homelessness by 2030," added the minister.
He said he believes it is "important we set that as our target within this plan".
Mr O'Brien outlined some of the most recent statistics in relation to homelessness.
"We have over 8,000 people with no home but we have seen in the last year significant reductions, particularly in child and family homelessness.
"Unfortunately, we've also seen a stubborn plateauing of homelessness among single people, and we need more accommodation."
He added: "We need to focus more on one bedroom units in that space in particular."
Housing First - the mechanism that provides wraparound services - will be expanded.
"We have retention of 90% of tenancies in that space with over 600 tenancies .... we're going to increase that over the next five years to a further 1,200, and indeed up to 1,500," he said.
A homelessness oversight committee will be in operation and adequate resources are being invested to work towards the 2030 target, added the minister.
He said the committee will include the stakeholders and our NGOs who "I work with every single week to make sure the focus is on continuing to drive down homelessness in every thing that we do as a Government".
Tánaiste Leo Varadkar has said "it is immoral" that there are vacant homes during a housing crisis.
"To me it's immoral that during a housing crisis that anyone would leave, you know, a house vacant or an apartment vacant for a prolonged period of time," he said.
"We have to put a stop to that."
Mr Varadkar said that the Government has yet to decide how long a house must be vacant before its owner is liable for the new vacant property tax that it is planning.
He said that decision cannot be taken until more data has been collected in November.
He added: "The data that we have on vacancy isn't very reliable at the moment, so you'll often hear very high numbers of vacant homes in Ireland, sometimes because they're vacant on census night.
"But a house could be vacant on census night for all sorts of reasons, it might be for sale, the person might be away for the weekend.
"That [information] is all being collected in November as part of the revaluation, and then we'll know what are the real reasons for homes being vacant and how long are they vacant for."
