Only one of the nine residents has decided to leave after Masonic Care Tasmania spoke with them individually on Wednesday morning.

They were offered temporary accommodation in Quest apartments while their properties were assessed, but a resident who was ordered out of a house on the same street more than one year ago was still yet to return.

The mould was believed to be behind walls and ceilings in eight houses on Docking Court, and the possible spread of spores meant residents were unable to bring their belongings.

Resident Kay Decker said the short notice made it impossible for the residents - who are mostly in their 80s - to put in place arrangements in case they could not return.

"We've had some legal advice, and that advice was for us to stay put," she said.

"You can't just walk out and leave your life at such short notice like this.

"We want to be offered some choices. We want to have a bit of control of the whole situation.

"They indicated to us that they would have to pull the houses down. That means we could end up living in a serviced apartment without our belongings for years."

The houses were built in 2011 and are owned by the residents themselves, while Masonic Care Tasmania retains ownership of the land.

Masonic Care Tasmania chief executive officer Jackie Howard said they were working individually with the affected residents.
