The parents of a child with autism have appealed to Taoiseach Enda Kenny "not to let us become homeless".
Gillian Murphy and her partner Damien Moore are parents to three children - one of whom has autism.
"We would tell the Taoiseach not to let us become homeless. We would tell him 'Help us. Change the law'," Ms Murphy said.
"We're supposed to leave our home on May 27. We're not leaving. There's nowhere else for us to go," she said.
"There's no houses for rent, especially in Dublin 15. We have a child with autism so we have to stay in Dublin 15 for him to be looked after. If we move out, then all his services are gone and we'd be back at the bottom of the list again," said Mr Moore.
They are among the 40 families in Cruise Park Drive in Tyrrelstown in west Dublin who received notification from the Twinlite company to vacate their home.
The company informed them their rental lease will not be renewed over the next 12 months.
The company reportedly plans to sell the properties.
They were among a number of families who held a protest outside the Dail.
The Tyrrelstown Tenants Action Group wants a change in the law that would prevent tenants from being obliged to move out of their homes if the landlord is selling the properties.
The family was among the group of protesters who were later admitted to the public gallery in the Dail prior to a scheduled debate on homelessness.
Anti-Austerity Alliance TD Ruth Coppinger said she would be raising the tenants' cases in the Dail.
"We've been warning for ages that selling a property is a legal and legitimate way to get rid of people. There is no way that 100 families in Tyrrelstown should have to move out of the area."
