Fianna Fáil says it still believes a rent freeze would be unconstitutional.
The party has held discussions with the Green Party on a range of issues as part of efforts to form a government.
Reports this morning had suggested Fianna Fáil might be willing to look at the option of a short-term rent cap as part of their efforts to reach an agreement.
During the election campaign, the party insisted such a freeze was not legally possible and would interfere with property rights.
Housing spokesperson Darragh O'Brien this afternoon said the idea was raised during discussions - but insisted their own stance has not changed.

He said: "Our position has not changed on it: the legal advice that we got is the same that we got a number of weeks ago, before the general election.
"What we're open to doing on any matter is actually looking at what others will say.
"We've had an exchange of views: that's what discussions and negotiations are about."
Earlier, Fianna Fáil TD Anne Rabbitte - who is part of the negotiating team - said everything has to be on the table in the talks with other parties.
She told Newstalk Breakfast that she wasn't part of a housing briefing yesterday, but said nothing can be ruled out as "we're in the middle of a housing crisis".
The Greens also held lengthy policy talks with Sinn Féin earlier this week, as Mary Lou McDonald continues her own own government formation efforts.
