Vacant hotels, old commercial buildings and empty convents could all be used to house Ukrainian refugees.
The Housing Minister says a nationwide trawl of around 500 larger buildings across the country has been carried out in recent weeks.
Since the start of the Russian invasion on February 24th around 22,000 Ukrainian refugees have arrived in Ireland fleeing the war in their home country.
Meanwhile, Government will also discuss tomorrow if people should be paid to house those fleeing the war.
Minister Darragh O'Brien says there needs to be a medium-to-long-term plan.
"There's no question that many of those arriving on our shores now are going to be here for a considerable length of time.
"We reckon there are about 8,000 homes that are vacant because of the conditions under the Fair Deal Scheme on a rental.
"Tomorrow, we expect a memo to be brought [to Cabinet] to bring that forward so we can have legislation passed by the summer."
Here's the latest on what is happening in the Russian invasion of Ukraine which is now in its seventh week:
