Premier Gladys Berejiklian says the system of regulation in the building industry is not working, after the Herald revealed the evacuation of a third apartment building in Sydney.
As the state opposition called for an immediate response to the growing number of building defects emerging in the city, Ms Berejiklian said she wanted to "assure the community that we know there's a problem.
"We know there's a gap in legislation," she said. "We allowed the industry to self-regulate and it hasn't worked. There are too many challenges, too many problems, and that's why the government's willing to legislate."
One of the reforms proposed by the Berejiklian government is the creation of a "building commissioner" position, which would have power to investigate construction sites.
Ms McKay called for that role to be established immediately, and described the situation as a "ticking time bomb".
"I think we will have more and more of these buildings come to light," she said. "Right now we have no building commissioner in place because this government won't release the details.
"If you are serious ... then tell us about the building commissioner. Put that commissioner in place right now, ensure they are resourced, and ensure they have the power to be there."
