200 extra emergency beds are being made available in the city by December.
That's among the announcements made by Housing Minister Eoghan Murphy this evening, after an emergency summit on housing.
100 of the new beds are expected to be in place by the end of next month.
He's also ring-fenced €10 million in additional funding for family hubs.
Minister Murphy says 800 extra social houses will be built across the country in 2018 due to a policy shift from acquisitions to direct build programmes.
That's on top of 3,000 social homes already announced.
The Government also says homeless families in Dublin wishing to move outside the capital "will be facilitated where possible".
