A parliamentary committee report has called for the establishment of a separate building commission and a dedicated building minister to improve standards across the construction industry in New South Wales.

The first report from the Public Account Committee has made 19 recommendations to the NSW Government in the wake of major structural problems at Mascot Towers and Opal Tower at Sydney Olympic Park.

One of those recommendations is the establishment of a sufficiently resourced building commission which would operate as an "independent statutory power" alongside a dedicated building minister to oversee the state's construction industry.

Parliament is currently debating a bill to create a new registration system for the industry, and to make it easier for owners to pursue damages.

But Greens MP David Shoebridge said the government's current piecemeal legislative approach was not enough to address the loss of confidence in the industry.

"Every stakeholder said that this industry needs root and branch reform … this industry needs a single building act that is governed by a senior minister," he said.

"But more fundamentally, we can't just rely on the current regulators and the current crop of politicians to make the industry safe.

"We need a building commission, not just a building commissioner."

The report also calls on the government to extend statutory warranties on building defects to a minimum of seven years to allow home owners to take out comprehensive insurance.

Mr Shoebridge said the government also needed to come up with a proper assistance package for residents affected by flammable cladding as well as structural issues in their buildings.

"We had homeowners in tears about the personal, financial and emotional cost that they are facing," he said.

"Individuals who had bought a home expecting the government had standards in place to make that home safe and fit for purpose, and instead finding the government had fled the field."

Labor's John Graham said while the report only touched on the issue of flammable cladding, the issue would be investigated with a further hearing in December.

"The more we looked at these issues, the more worried we were about the state of apartment building in NSW," Mr Graham said.

"The most concerning evidence we received was that the Building Commissioner had advice sitting on the desk of the Minister about how to deal with flammable cladding and today, that has still not been acted on.

"It has been in Victoria — it has not been in NSW. There is no plan to deal with that and we need a plan to deal with flammable cladding on buildings in NSW."
