The Tánaiste Joan Burton has said Dublin City Council and the Fire Brigade are engaging with the 300 families who could be forced to evacuate from an apartment block tomorrow.
Residents at Longboat Quay in the Dublin Docklands have been told they will face a fire brigade evacuation order, unless they provide €4m for remedial works.
The Taoiseach Enda Kenny has been asked to call the site's developers to ask them to pay for the repairs.
Ms Burton says local authorities will work with the residents.
She said: "It is part of this legacy of, it would appear, inadequate, in this case, fire protection measures being in the apartment complex. Dublin city council obviously have a role to play in this as obviously have the regulatory authorities.
"The Department of the Environment and the city council as well as fire brigade are engaging with residents."
