The Productivity Commission’s report estimated that restrictive zoning laws were the largest regulatory cost on new homes, at 50-80 per cent.
For units, which use less land, the greatest regulatory cost is administrative and assessment paperwork, at 33-36 per cent.
The government costs on a home in Brisbane were about the same as a home built in Melbourne, while regulation cost the most in Sydney.
Wood said safety and quality regulations were essential to ensure consumer confidence in buying a home, but the balance with ensuring home ownership was affordable had been thrown out of whack over decades of creeping regulatory requirements.
“It’s a burden that sort of ratchets up, sometimes for good reasons, but often without enough consciousness of the trade-offs, and that trade-off is ultimately making houses more expensive and less easy to supply, and in a time where we have a real affordability challenge,” she said.
Wood said the federal government could focus on incentivising regulatory change that states oversee, such as in planning or heritage laws, rather than with housing targets – the success of which can be influenced by a range of factors not always within the states’ control.

Housing Industry Association chief economist Tim Reardon said his organisation’s modelling suggested the cost in Sydney and Melbourne, where a large portion of the population lived, was much higher.
He said HIA estimates 50 per cent of the cost of a new house and land package is regulatory.
“The upper bound that [the Productivity Commission] have there reflects the costs in Sydney and Melbourne … so it’s more accurate to reflect on that upper bound as being a conservative estimate of what the average Australian incurs,” he said.
He said a move to pause the National Construction Code – which had blown out to thousands of pages of requirements on new builds – was welcome but there was more to do to bring down house prices.

“That trade-off between accessibility and energy efficiency has taken precedence over affordability, and that same decision-making process we’ve seen over the course of 25 years is at the core of why housing is now very unaffordable,” he said.
Reardon said the system should be reformed so repeat approvals were only required once, and to encourage foreign investment in construction.
Master Builders Australia chief executive Denita Wawn said the report should be a wake-up call to the federal government, which should reassess regulation’s effect on growth.

“The growing volume of regulation imposed by all levels of government, including through the NCC, has contributed to poor construction productivity,” Wawn said.
She called on the government to slash red tape by 25 per cent, and said a fundamental shift to regulatory norms was required.
“Setting a target to reduce red tape and having a clear agenda for regulatory reform and regulatory burden reduction as recommended by the PC is critical to supporting a sustainable and viable building and construction industry over the long term,” Wawn said.
