Inner City Helping Homeless has suspended a senior member of staff.
An independent investigation will be carried out within the charity after "serious matters" came to the attention of the board in recent days.
The board say they're mindful of the role its volunteers play in Dublin everyday and say it will take every step to ensure the welfare of service users.
The board says it will continue to take "whatever steps are necessary" to protect its work.
Statement by the Board of Inner City Helping Homeless: "In recent days, serious matters have come to the attention of the board. We immediately initiated an investigation and commenced an independent process which we expect recommendations from shortly. In the interim, we have suspended an employee and the use of a separate service provider. The board has also moved to appoint an independent senior counsel, Mr. Remy Farrell to fully evaluate issues of concern.
"We are in communication with the Charities Regulator.
"The board is mindful of the vital role our team of volunteers and staff play in the daily lives of those sleeping rough in Dublin. We are grateful to them and our wider network of supporters. We as a board will continue to take whatever steps are necessary at this time to protect and enhance the invaluable work of the organisation and the welfare of all service users."
