Sinn Féin's Pearse Doherty criticized the government over house prices during Leaders' Questions.
However, the Tánaiste pointed to Sinn Fein's record in Northern Ireland.
"You built fewer social houses in recent years in Northern Ireland than we've added to the stock here, south of the border, certainly since 2016."
"Sinn Féin has not opposed a single social or affordable housing development in Dublin," Pearse Doherty responded.
"But in contrast to that, your councillors who voted against thousands of social and affordable housing in Clondalkin and in Tallaght."
Leo Varadkar then asked for it to be noted that "it was the deputy that got personal."
