But now a backbencher, Morrison has no claim on the property.
"(He's) in the process of moving out," his spokesman said.
"There's two weeks you have to move out.
"That's protocol. So there's no delay."
Morrison had already moved out of The Lodge, the Prime Minister's primary official residence in Canberra.
Rumours of his refusal to budge created a storm on social media, with the hashtag #SquatMorrison emerging on Twitter.
Morrison's layover at the house is slowly approaching Howard's extended exit, after he famously took 16 days to even begin the process of moving out back in 2007.
A removals truck was seen at the Lodge last Thursday to help Morrison and his family move out.
Flood victim Nikki Durant, who used to clean the Morrisons' pool has been living at the family's home in Sydney's Sutherland Shire, after her Northern Rivers home was destroyed in the devastating NSW floods.
Morrison stood down as Liberal party leader following his historic defeat at the federal election.
He has confirmed that he will stay in Parliament as the member for the Sydney seat of Cook.
