The Convention Centre Dublin (CCD) could be used for a sitting of the Dáil to elect a Taoiseach.
The Dáil Business Committee has asked Oireachtas officials to examine whether it could accommodate all TDs, while maintaining social distancing rules for public health.
It was agreed earlier, with the decision expected to be signed off later this week.
Social distancing rules means the Dáil itself is too small to host a potential vote.
Social Democrats co-leader Róisín Shortall, who sits on the Dáil committee, said there are not a lot of options.
"We discussed a number of pressing issues in relation to how the Dáil might continue to operate, even in limited format.
"While over the next few weeks we are going to be meeting in Leinster House with reduced numbers, the question arises of what happenes when we get to a point where a Taoiseach has to be elected - or where emergency legisaltion needs to be passed where we would need all 160 members of the Dáil to be present.
"And it's not possible to have that in Leinster House and to observe safe social distancing.
"So we've been checking out other potential venues - the most likely one at this point is the Convention Centre.
"It's really probably the only venue within the Dublin city area that could cater for that number of people in safe circumstances."
She added that the Clerk of the Dáil and his officials are working to finalise the arrangement.
Another meeting will be held on Wednesday.
The CCD has been closed since March 24th, in line with coronavirus measures by the Government.
Its main auditorium has a stall capacity of 898, and circle capacity of 1,097.
It has previously been used for major events, including Irish citizenship ceremonies.
It comes as Taoiseach Leo Varadkar said Fine Gael is ready to make an agreement with Fianna Fáil.
The two parties are working on a framework document on policy on how a new Government may operate.
If agreed, the plan will then be pitched to other parties for consideration.
The Green Party, Labour and the Social Democrats have previously said they are not interested.
However Ms Shortall said her party will look at the document when it is published.
