A record number of people are registered as homeless, official figures show.
The Department of Housing says 13,866 people accessed emergency accommodation in March.
That figures includes 4,174 children.
It represents a 16% increase in the number of people homeless when compared to the same time last year.
The figures do not include those rough sleeping, domestic violence refugees and those on streets seeking asylum.
Dublin Simon Community said 111 offers of emergency accommodation are made nightly in the capital, with only four households a day in the region exiting homelessness to a home.
'Heartbreak and struggle'
Dublin Simon CEO Catherine Kenny said the impact on children is 'immeasurable'.
"Behind these numbers lie stories of heartbreak and struggle, and the daily and nightly routine of homelessness is starkly evident.
"The escalating trend of adults and children seeking emergency accommodation each day and night is untenable.
"Prolonged stays in emergency shelters strip away hope, leaving deep scars on mental and physical health.
"The impact on children is immeasurable, robbing them of their security and stability in some of their most important developmental years," she added.
'Moving too slowly'
Focus Ireland is calling on Taoiseach Simon Harris to 'take every action possible' to fast-track social housing.
Its CEO Pat Dennigan said things are moving too slowly for families.
"We welcome the Taoiseach’s recognition that the exiting new housing targets for social, rental, and private housing are inadequate and will be increased," he said.
"However, things are moving far too slowly for the over 4,000 children who are homeless in Ireland.
"This massive increase in homelessness was not inevitable and its root cause is the repeated failure to deliver sufficient social and affordable housing".
Focus Ireland said it recently wrote to Mr Harris, making the case that with "the right policies homelessness can be solved".
The charity added that the Government could act today to prioritise moving many families and individuals out of long-term homelessness, and straightforward changes could make "rapid and significant differences" to people’s lives.
