Certifiers, council and building disputes in Box Hill NSW

Box Hill is in The Hills Shire. Your construction certificate and the mandatory inspections attached to it come from a principal certifier, and it is worth being clear that those inspections exist to allow the certificates to issue, not to protect you. They do not produce a defect list you can act on. Your protection sits elsewhere: statutory warranties under the Home Building Act 1989, six years for major defects and two years otherwise, and the Home Building Compensation Fund through icare where the builder cannot complete. Where a dispute cannot be resolved directly, NSW Fair Trading's complaint and inspection process comes first, and NCAT after that.

Certifiers, council and building disputes in Box Hill NSW: common questions

Is the certifier's inspection enough on its own?

No. It confirms the build meets what the certificate requires at set milestones. It will not tell you a bolt group is short or a membrane has pinholes, and it is not carried out in your interest.

What is a major defect under the Act?

Broadly, a defect in a major element that makes the home uninhabitable or unusable for its purpose, or threatens collapse. The six year warranty applies to those and two years to everything else, which is why the category a defect falls into matters.

Can a defect report be used at NCAT?

It is useful evidence and often settles matters earlier, but the tribunal expects an expert witness report prepared to NCAT Procedural Direction 3. We prepare those separately.
