Fianna Fáil is refusing to rule out supporting a possible no confidence motion in the Minister for Housing Eoghan Murphy.
Sinn Féin has said that it is actively considering tabling such a motion in the minister before the Dáil summer break next month.
Under the Confidence and Supply Agreement Fianna Fáil is bound to vote against or abstain in any confidence motions in the Government or its ministers.
"If Sinn Féin table a motion on anything ... we'll assess that motion, it's as simple as that. I can only assess what's tabled and I'll do that with the party's frontbench and the parliamentary party, " the Fianna Fáil Housing spokesperson Darragh O'Brien said.
Mr O'Brien also accused Taoiseach Leo Varadkar of engaging in juvenile and pathetic games.
This follows reported comments from the Taoiseach last night that a Sinn Féin motion could potentially trigger a snap election.
However, Fianna Fáil said the focus should remain in delivering more housing.
"If an election happens an election happens, but what we are focused on is trying to improve the quality of lives of our citizens
"Would an election improve that further? Right now I'm not so sure but we've never shied away from an election and that is something we would never do
"A good housing budget and real progress for the people in Ireland on housing ... that should be the priority and not an election," Mr O'Brien said.
Sinn Féin Housing Spokesperson Eoin Ó Broin said his party was actively considering tabling the no confidence motion before the end of the Dáil term and it's a high item on the party's agenda.
"It's clear that Eoghan Murphy is failing ... he's not up for the job." he said.
People Before Profit TD Richard Boyd Barrett said housing should be the issue that decides the outcome of any election.
Meanwhile, the Taoiseach has accused Sinn Féin of cynicism by fomenting a possible confidence motion on the Government over the housing shortage.
He said Sinn Féin was targeting the Housing Minister Eoghan Murphy in the hope of triggering a snap election.
He said Sinn Féin couldn't lose. If the confidence motion was lost, there would be an election, but if it was passed Sinn Féin could embarrass Fianna Fáil, he said.
"It's entirely tactical. It's entirely cynical," he said.
