The number of people in homeless accommodation has gone above 10,000 for the first time since February 2020.
According to figures from the Department of Housing for April, there were 10,049 in hotels and B&Bs - up 2% from March's total.
In Dublin there are 4,991 homeless adults and 2,209 children.
The total from the Government doesn't include Ukrainian refugees in pledged accommodation, Direct Provision, women in refuge centres or rough sleepers.
"In the greater Dublin area, we have almost surpassed the number of people in emergency accommodation during the homeless crisis peak of 2019.
"Almost three years on, the wider environment is even more challenging and complex as house prices and cost of living increase while the supply of social and affordable housing remains critically low. On the streets, our outreach team is now meeting an increasing number of women who need access to safe female accommodation but availability cannot keep up with demand.
"At this point, there is not only an urgent need to stem the flow into and provide move-on options out of homelessness, but the emergency accommodation system itself is bursting at the seams and staff are working at and beyond capacity to meet the growing demand for services.
"The detrimental effects of long-term stays in emergency accommodation on mental and physical health are well documented. People are being failed by the system and as a result of that failure will need even more support in the future - it is a vicious circle with no clear exit point."
