Clauses that deal with defects

Defects are usually defined within the Statutory Warranties, which you will find listed in your contract.

If you’re using the Fair Trading contract​

You should also look at pertinent dates: the commencement of works, building period, and practical completion.

The only time you’ll know if there is a building defect is after the handover of the property upon practical completion.

Note that practical completion is computed after the building period commences.

Here’s where to find them:

If you’re using the HIA contract
Schedule 1 Item 6 Building period
HIA Contract Building Period Clause
Clause 12 Commencing the Building Works

Clause 21 Practical Completion

If you’re using the MBA contract

When defects become an actionable wrong

So, supposing the building works have reached the stage of practical completion. You now have the right to inspect the works and the premises. 

What should you do if upon inspection of the premises after practical completion, you find that there are defects or incomplete works?

Generally, you send the Builder a list of defective and incomplete works, within what’s called the “Defects Liability Period.” This then obliges the Builder to rectify the defects in the notice. The details and timelines would depend on the contract you’re using.

If you’re using the HIA contract
Clause 24 Defects Liability Period
HIA Contract Defects Liability Period Clause
If you’re using the MBA contract
Schedule 2 Item 7
Clause 24 Defects Liability Period
MBA BC4 Contract Defects Liability Period Clause
If you’re using the Fair Trading contract​
Clause 23 Defects Rectification

Dispute Resolution

What if the Builder refuses to rectify the defects?

If the Builder refuses to rectify the defects after you’ve given them notice to do so, you may resort to dispute resolution.

Usually, the procedure is as follows:

  1. Give written notice to the builder, setting out the matter in dispute. In this case, building defects.
  2. You and the builder must meet within a certain number of days, to attempt to resolve the dispute, or to agree on methods of doing so.
  3. If the dispute is resolved, you write down the resolution and sign it.

The finer details of the dispute resolution procedure depends on which contract you’re using.

If you’re using the HIA contract
Clause 35 Dispute Resolution
HIA Building Contract Dispute Resolution Clause
If you’re using the MBA contract
Clause 26 Dispute Resolution
MBA Contract Dispute Resolution Clause
If you’re using the Fair Trading contract​
Clause 27 Disputes
Office of the Fair Trading Contract Disputes Clause

If the dispute remains unresolved despite undergoing Dispute Resolution

  1. If, despite attempting to settle the matter between yourselves, the dispute persists, you may opt to bring the matter to the Office of Fair Trading, where you and the builder may be instructed to undergo ADR (Alternative Dispute Resolution).
  2. If the dispute still remains unresolved after taking it to Fair Trading, you will be given a certification to lodge a complaint with NCAT, where the matter will undergo directions hearings. A final hearing may be had where the disposition of the tribunal will be made.
  3. If, after Fair Trading, the dispute is still unresolved, or if you are not satisfied with the tribunal’s decision, then you may file a complaint in court.
