How to cure the leaky home crisis

Philip O'Sullivan

The weathertightness crisis has not been properly resolved.

What is needed is a national home warranty scheme, owned and run by the industry on a non-profit basis, for the benefit of owners of new homes.

The government has never come to grips with the underlying drivers of behaviour that cause problems like leaky homes.

The Department of Building and Housing, now part of the Ministry of Business, Innovation and Employment, has not been a success. It has suffered from political interference and inept policy formulated by people with no understanding of building.

They often resemble World War I generals headquartered in their chateaux asking why the soldiers can’t break through enemy lines, and then ordering more of the same.

Misplaced expectation

Last year a member of the landmark report on weathertightness (the Hunn Report), David Kernohan, also lamented the expensive and lengthy litigation that dominates the resolution process. But with a legally based system, what else would you expect?

The misplaced expectation with the Weathertight Homes Resolution Services Act was that owners, builders, councils and designers would happily mediate their way to settlement. 

But who wants to pay hundreds of thousands of dollars to repair a failed building due to inadequate systems and non-durable materials foisted upon them by others?

Liability is like pain. No one wants it but, without it, poor behaviour flourishes.

Unfortunately, in this litigious environment that the government has created and keeps on reinforcing, ratepayers have become the unwitting insurer of an industry that has no adequate means of governing and regulating its behaviour.

After the recent Supreme Court Spencer on Byron decision, ratepayer liability for all types of buildings – not just people’s homes – looks set to expand.

Yes, the Law Commission is investigating the idea of replacing joint and several liability (or “last man standing”) with proportionate liability. This would seem fairer to defendants but would leave most claimants, especially homeowners, considerably poorer.

After all, a 20% victory against the last man standing – usually the council – may not even cover the claimant’s legal costs.

During the late 1980s and 1990s self-interest within the various sectors of the industry created what in the end became a perfect storm of risky designs built with unreliable systems and non-durable materials.

Our understanding of how buildings perform was lacking; the science was primitive. Without proper understanding, education when it did occur was inadequate. And when it came to accountability, everyone ducked for cover, or ran to their lawyer.

We now have better cladding systems and materials. Councils have improved but they are now pushing liability back to the industry. Who can blame them? The problem is the industry at present can’t deliver. So what will?

I believe a national home warranty scheme, owned and run by the industry on a non-profit basis, for the benefit of owners of new homes, would help.

Risk focused

Such an organisation must be technically competent and risk focused. It would need to be a voluntary scheme for homeowners, so it can avoid future political interference.

High-end risky designs and commercial buildings would not be included. It would then be possible to differentiate most of our homes from such buildings and allow government to disentangle the ratepayer from this unwanted and unnecessary burden.

This organisation would approve and monitor the systems and materials that make up residential buildings, as well as the designers and the builders; not just the people but the companies and the people behind these companies.

It would approve the designs, monitor the construction (similar to building inspection, but smarter) and, if things go wrong, investigate the cause.

It would make sure whoever is at fault puts it right and it would underwrite this process. It would work for the benefit of the homeowner and the industry. Any surplus income would be retained and alleviate government of the costs to some degree.

Most importantly, such a body would provide timely advice, educate the industry and seek to avoid repeat failures. This feedback system is the best way to deliver quality outcomes. The current system generally lacks this – feedback can be inhibited and even prevented by commercial and legal pressures.

Successful precedents

Internationally, such national warranty schemes do exist. They have quietly and successfully performed for many years. They are not insurance companies. Insurance relies on the “system” to get things right and, if this fails, insurers seek to avoid or reduce payouts and then hike their premiums.

Warranty companies, to be successful, achieve this by identifying and managing risk at all levels of the industry and at all stages of the building process.

To get such a scheme established would initially need government leadership and support. Once established, such schemes become self-funding. Coincidentally a scheme like this would achieve the government objective of an effective national consenting and compliance scheme.

There’s no need for another royal commission. A properly established and managed home warranty scheme is the best solution. Now is the time for leaders, both in the government and industry, to grasp the initiative, provide the resources and work together to make this a reality.

Thank God for comment on this issue by someone who knows what they are talking about. The banks and insurance companies have ample incentive, influence and clout to make this happen.

The only necessary ingredient is for the Government to legislate that Councils are responsible only for health and safety of buildings, not quality and durability. At a stroke that removes the current ratepayer underwriting of durability risk - as well as a mountain of bureaucracy and cost.

With that useless nonsense gone, mortgage lenders and insurers will force a market solution of the kind Mr O'Sullivan envisages.

How about Architects design water proof housing and councils check the correct construction just like everyone thought was happening

How about architects check correct construction of their own designs instead of having to hand it all over in a massive pile of paper and detail to a bunch of bureaucrats with no architectural qualifications whatever?

As used to happen until the Vogons took over the building industry?
