Meath County Council can issue a fire safety notice on houses in Riverwalk Court in Ratoath from today.
The development needs over €1.5m worth of fire safety work carried out.
Residents and the developer had until last Friday to commit to carrying out the remedial works.
That failed to happen which means the local authority can now issue a fire safety notice.
Spokesperson for the residents, Mark Fitzmaurice, says they are facing into an uncertain Christmas.
"The deadline was last Friday, they're going to review the submissions this week - so we don't think we're going to hear from Meath County Council until at least the new year now" he told Newstalk Breakfast.
"So the residents are facing into a Christmas with this...uncertainty hanging over their heads" he added.
