HBCF insurance and your granny flat: what you are entitled to

Home Building Compensation cover, usually called HBCF, is required for most residential building work in NSW over $20,000 including GST. It protects you if your builder cannot finish the job or cannot fix defective work, because they have become insolvent, died, disappeared, or had their licence suspended for not complying with a court or tribunal order to pay you.

It is last resort cover. That phrase does a lot of work, and this article explains what it means for you.

When it is required, and when it must be in place

HBCF is required for most residential building projects over $20,000 including GST, unless the project is exempt. A granny flat is well over that threshold.

The timing matters as much as the requirement. The builder must have cover in place before they start work or take any payment, including a deposit.

If you are asked for a deposit and told the insurance is coming, that is the wrong sequence.

What “last resort” actually means

HBCF is not general building insurance and it does not cover ordinary disputes.

It steps in only when your builder cannot put things right themselves. According to icare NSW, that usually means the builder has:

  • become insolvent, for example bankrupt or in liquidation
  • died
  • disappeared and cannot be found
  • had their licence suspended for failing to comply with a court or NSW Civil and Administrative Tribunal order to pay you money

If your builder is still trading, you generally need to pursue the issue with them first, including through dispute resolution.

What you may be covered for

If you find a defect in the last 6 months of the cover period, you may have another 6 months to notify.

The claim limit

There is a maximum claimable on each policy:

Policy issued
Maximum
Before 1 February 2012
$300,000
Other policies
$340,000
Maximum
$300,000
Maximum
$340,000

That total is for the property, including any claims made by previous owners. It is worth knowing if you are buying a property where work has been done before.

What HBCF does not cover

  • General wear and tear
  • Maintenance issues
  • Changes of mind about design or materials
  • Work done by unlicensed builders
  • Disputes where the builder is still trading and able to fix the problem
  • Costs outside the policy time limits
  • Costs above the maximum cover amount

That fourth one deserves emphasis. Work done by an unlicensed builder is not covered. Using an unlicensed builder to save money removes the protection that exists precisely for when things go wrong.

How to check cover exists for your job

You do not have to take anyone’s word for it. icare maintains the HBCF Certificates Register, accessible through Verify NSW.

The register shows:

  • whether a policy was issued
  • the insured builder
  • the property address
  • whether any claims have already been paid

Check it before you pay a deposit, and check it again before construction starts. It takes a couple of minutes.

That last field is also useful if you are buying a property with an existing granny flat, because prior claims count toward the same policy limit.

What this means practically when choosing a builder

Three things follow from all of the above.

  • Verify the licence. Unlicensed work is not covered at all, so the licence check is also an insurance check.
  • Sight the certificate before paying anything. Cover must be in place before work starts or payment is taken.
  • Check the entity matches. The insured builder on the certificate should be the same entity signing your contract.

Frequently asked
questions

They are commonly used to mean the same thing in NSW. The current scheme is the Home Building Compensation Fund, administered by icare.

The builder takes out the policy and the cost is generally reflected in the contract price. The policy protects you as the homeowner.

No. It does not cover changes of mind, wear and tear, or maintenance. It covers incomplete work and defective work, and only once a trigger event has happened such as the builder becoming insolvent.

HBCF generally will not respond while the builder is still trading and able to fix the problem. The path in that situation is to pursue the builder directly, including through dispute resolution or NCAT. NSW Fair Trading can explain the options.

In some cases costs directly related to investigating a problem, assessing the cost or supporting a claim may be considered, but they are not automatically covered. Once a formal claim is lodged, icare states it cannot pay legal costs where you keep a lawyer involved in managing the claim.

The claim limit is $340,000 for policies other than those issued before 1 February 2012, which are $300,000. The register will confirm a policy exists and whether prior claims have been paid against the property.

Ask for the certificate

Any builder should be able to produce the HBCF certificate for your job before you pay a deposit. If asking feels awkward, it should not. It is the protection the scheme exists to give you.
