The company responsible for illegally allowing people to live in the 61 Molesworth St building had illegal tenancies in another quake-damaged building earlier in the year.
PrimeProperty Group may face prosecution for renting office space to people in the building, which will be torn down after last week's earthquake. It has now been revealed the company also had people living in a quake-damaged building on Wakefield St.
Wellington City Council spokesman Richard Maclean said council received a complaint in September about people living illegally in the former Greater Wellington Regional Council building on Wakefield St.
"Our inspectors went along and inspected the building. It was obvious that it had been used as accommodation," Maclean said.
"It appears that it had been used for fairly large parties on one floor."
