Owner Builder Warranty

An Owner Builder Warranty is essential for anyone who builds or renovates their property without hiring a professional builder. It ensures that future buyers are covered for defects or issues that may arise after the sale.

In states like NSW and VIC, an Owner Builder Warranty is mandatory when selling an owner-built property. It’s also necessary for securing home owner builder insurance, which protects buyers in case the owner builder can’t address defects due to death, insolvency, or disappearance.

At Jim’s Building Inspections, we offer owner builder inspections to help ensure your property meets building approval and owner builder building permit requirements, making sure it’s ready for sale.

An owner builder inspection is key to securing an Owner Builder Warranty and ensuring your property is compliant with regulations. Here’s why it matters:

  • Compliance with Regulations: An owner builder inspection confirms your property meets building approval and owner builder building permit requirements.
  • Protect Future Buyers: The inspection ensures that any defective building work is identified and addressed before selling, making it easier for buyers to secure home owner builder insurance.
  • Peace of Mind: A clean inspection report ensures buyers that your work is safe and compliant, reducing risk for both parties.

This inspection is essential in NSW and VIC, where an owner builder warranty is required by law for properties being sold.

Chirag was extremely efficient and easy to communicate with. He was also in constant communication and even gave us a phone call to run us through the final report. Highly recommend him and Jim's Building Inspections Kurrajong.
Alexandra Churchill
In the buying space, John is our go-to and first choice for pre-purchase inspection reports. Helpful and pragmatic, he has always taken the time to talk me through any aspect of his reports (I've bought/ commissioned many!), better still – he provides realistic solutions to any finding. John is responsive, knowledgeable and very experienced. I would recommend him to everyone.
Kathy Jarvis
Highly recommend Nick — he was punctual, professional, and extremely thorough. He provided a detailed report and took the time to clearly explain and point out any areas of concern while on site. Great service all around.

I highly recommend Laura from Jim’s Building Inspections. She was incredibly thorough and took the time to walk through the entire property with me, making sure I fully understood what I was buying before moving forward. The agent had advised there were no issues and encouraged me to rely on the vendor’s report, but Laura’s inspection revealed things that would have otherwise been missed. Thanks to her, I can go into this purchase fully informed and without any unexpected surprises.

As a buyer’s agent, I work with a lot of different building inspectors, and I can honestly say John is one of the best I’ve dealt with.

I trust him so much that I’ve used him not only for my clients, but also for my own personal property purchases. That says everything.

John is thorough, experienced, and tells it exactly how it is. He doesn’t just point out obvious issues, he gives practical advice, highlights what really matters, and helps you understand the true cost and risk behind a property.

There have been multiple occasions where John’s inspections and advice have saved me and my clients a significant amount of money, whether that was avoiding major hidden problems, negotiating a better purchase price, or giving confidence to move forward on the right property.

He’s reliable, honest, and someone I genuinely value having on my side during a purchase. If you’re buying property and want someone who knows what they’re doing and looks after your interests, I’d highly recommend John.
James Trotter
John completed our building and pest inspection on short notice and delivered a far more detailed and thorough report than the one provided by the agent. His attention to detail and clear explanations gave us a much better understanding of the property and highlighted issues that would have otherwise been missed. Highly recommend his service
James Ray
John completed multiple building and pest inspections on short notice and delivered a far more detailed and thorough report than the one provided by the agent. I’ve come across multiple reports he’s done that were commissioned by vendors, and they are a lot more comprehensive and transparent than other vendor-commissioned reports I’ve seen. We’ve even engaged John to carry out inspections on properties that already had reports available, simply because of the quality and level of detail he provides. Professional, reliable, and easy to deal with—highly recommend his service

We recently had a building inspection carried out by John from Jim’s Building Inspections, and I couldn’t be more impressed with the experience. From start to finish, John was extremely professional, punctual, and thorough in his approach.

He took the time to carefully inspect every aspect of the property and explained his findings in a clear and easy-to-understand way. What stood out most was his attention to detail and willingness to answer all of my questions without rushing. It gave me real confidence in the process and peace of mind about my decision.

The final report was delivered promptly and was very comprehensive, with clear explanations and photos to support his findings. It’s obvious that John takes great pride in his work and genuinely cares about helping his clients make informed decisions.

strata inspection report

If you’re an owner builder, an inspection is vital to ensure your property meets safety and legal standards. Here’s why:

  • Compliance with Regulations: An owner builder inspection ensures your property meets building approval and safety standards, and helps secure home owner builder insurance.
  • Protect Future Owners: Buyers need assurance that your work is safe and complete. The inspection helps identify potential issues that could affect the property’s value and safety.
  • Insurance Requirements: Many buyers require home owner builder insurance, and the inspection report makes it easier to obtain insurance for the sale.
  • Prevent Future Costs: Catching issues early can save both you and the buyer from costly repairs down the line.

The inspection also provides necessary documentation for compliance in states like NSW and VIC, where owner builder warranty insurance is mandatory.

The owner builder home warranty insurance offers several benefits for both you and the buyer:

  • Protection for Buyers: Covers future owners if defects arise after purchase, especially when the owner builder is unavailable.
  • Increased Property Appeal: A property with an owner builder warranty and inspection is more attractive to buyers, who will have peace of mind knowing they are covered.
  • Compliance with Regulations: Ensures your property complies with legal requirements in states like NSW and VIC, making the selling process smoother.

Requirements for the sale of Owner Built properties and homes in Australia differ from state to state.

  • Sydney & NSW
  • Melbourne & VIC
  • Perth & WA
  • Adelaide & SA
  • Brisbane & QLD
  • Hobart & TAS

Generally the requirement is that if you go to sell the property you have Owner Built within a few years of completion (usually around 6 – 7 years) you may be required to have an Owner Builder Inspection Report completed.

This Report is provided to an Insurer who will issue a policy in favour of the purchaser. It covers the purchaser in the event you abscond or are otherwise unable to provide redress for defects in the construction you did as an Owner Builder. The Inspection Report identifies for the Insurer any defective, incomplete works and the use of second hand building materials all of which are excluded from the insurance policy.

Key information per state

Victoria

Owner Builders are defined as someone who undertakes building, renovation or construction works or the supervision of required subcontractors on a property they own:

An Owner builder report also known as a 137B report is required when a vendor is selling their property and has previously undertaken Owner Builder works of which

  • Exceeds the minimum value required for contracted building works
  • Requires a building / planning permit

In states like NSW, VIC and WA this is mandatory, while in other states it is advisable.

This report provides purchasers with peace of mind and gives Insurers the information required to issue a policy for the benefit of the purchaser.

New South Wales

Owner Builder Warranty Inspections are mandatory in NSW.

In NSW when an owner builder decides to sell a property, within six years of the completion of owner builder work, the Home Building Act 1989 requires that home warranty insurance cover be taken out.

This is required where the reasonable market cost of labour and materials exceeds $20,000.

Cover must be taken out by the Owner Builder and a consequent Certificate of Insurance be attached to the contract of sale for the property.

For these purposes, Owner Builder work is taken to have been completed on the earlier of the date of issue of an Occupation Certificate or the date 18months after the issue of an owner builder permit for the work.

The Owner Builder warranty insurance policy for the owner builder work provides cover to the purchaser of the property and subsequent successors in title where the purchaser is unable to have any defective owner builder work – not apparent at the time of purchase – rectified because of death, disappearance or insolvency of the owner builder.

Please note: where the Owner Builder contracts work valued over $20k to a licensed builder or trade contractor the builder or contractor must obtain home warranty insurance for the work, in this case the owner builder is covered by the home warranty insurance.

Pending Regulatory Change

Following the passing of amendments to the Home Building Act 1989 by the NSW Parliament recently, it is likely that as from 1st December 2014 the NSW Self Insurance Corporation, which administers the Home Warranty Insurance Fund, will no longer be able to provide home warranty insurance cover for owner-builder work.

NSW Fair Trading has issued an exposure draft of the Home Building Regulation and is presently considering feedback received before confirming the date of commencement of the legislative amendments.

This may mean that NSW will fall into line with states such as Queensland where no insurance for Owner Builders will be extended, at least by the Home Warranty Insurance Fund, managed by the State Government.

Monitor the NSW Fair Trading website for more details from December 2014 onwards.

Owner Builder Inspection Reports are carried out by Jim’s Building Inspectors that meet the NSW Fair Trading requirements below:

  • Licensed as a Builder
  • Hold the qualifications and experience that would satisfy the Fair Trading’s builder’s licensing criteria

And / or be a:

  • Registered Building Certifier or Inspector
  • Registered Engineer or Architect

NSW Fair Trading also includes the requirement that your Inspector must be independent of you, the Owner Builder.  For example, you should have no prior personal association (friend or professional colleague) or association by marriage or family, with your Inspector.

Some of the existing Insurers will request that the Owner Builder supplies with the Inspection Report, information regarding the prerequisites your Inspector has met above.

In NSW you will be required to cooperate with your Inspector to provide:

  • Documentation in relation to Development Consents, Construction Certificates etc., for the previous 10 years
  • List of all works done at the site

They would be submitted by you the Owner Builder as an Appendix to your Inspection Report.

Your inspector will also issue you with a statement providing permission for the report to be made available to third parties accompanying the report.

The Owner Builder Inspection Report has a maximum duration or life span of 6 months. For example, if you do the inspection and the property sale falls through, the same report can be used during the next 6 months.  However, if a sale occurs or settles at 6months + 1 day, a new report is required by the Insurer.

NSW is comparatively specific in their documentation for what must be included in an Owner Builder report generally, but all the factors excepting the two items noted above are catered for in the Build Inspect App.

Western Australia

Owner Builder Warranty Inspections are mandatory in WA.

In WA owner builders are responsible for the building work they carried out for a minimum of 6 years for works with a value of $20,000 or more.  However, unlike other states, this requirement excludes associated works like pergola’s, fences or pools.

If the owner builder sells the home within 7 years from the date a of a building licence or permit being issued they are required under the Home Building Contracts Act. 1991 to have in place a policy of home indemnity insurance.

This policy covers subsequent owners so that if problems develop with the building and the owner builder fails to rectify due to disappearance, death or insolvency, they are covered.

In WA it is called Home Indemnity Insurance.

Home indemnity insurance can be obtained by contacting an approved insurance provider.

South Australia

Owner Builder Inspections are not mandatory in South Australia.

It is however advisable best practice to have an Owner Builder Warranty Inspection done when selling a property within 6 years of the Certificate of Practical Completion being issued.

Whether you simply provide the potential purchaser with a copy of the inspection report as a form of disclosure during the sales process, or whether you go the additional step to take out a policy in their favour, an Owner Builder Inspection Report will facilitate confidence in the sale process.

Queensland

In Queensland it is mandatory to disclose to the purchasing party that the property was either built or renovated under an Owner Builder arrangement.

The QBCC provides specific instructions which your property conveyancer or solicitor will assist with.

The Owner Builder notice to the purchaser takes the form of:

  • details of the owner builder work done under the permit
  • the name of the permit holder who carried out the work
  • a statement confirming the work was done under an owner builder permit
  • the following notice: “Warning – The building work to which this notice relates is not covered by insurance under the Queensland Building and Construction Commission Act 1991”.

You must give the buyer 2 copies of the notice. The buyer must sign 1 copy and return it to you on, or before, signing the contract of sale.

Consequently it is not mandatory to have an Owner Builder Inspection Report done or to issue an insurance policy in QLD.

It is however advisable best practice to have an Owner Builder Warranty Inspection done when selling a property within 6 years of the Certificate of Practical Completion being issued.

Whether you simply provide the potential purchaser with a copy of the inspection report as a form of disclosure during the sales process, or whether you go the additional step to take out a policy in their favour, an Owner Builder Inspection Report will facilitate confidence in the sale process.

Conversely, many inspections of Owner Built or Renovated properties in Queensland are being requested by the purchaser in the form of additional scope of works in a standard Pre-Purchase Building and Timber Pest Inspection Report.

Tasmania

Builders Warranty Insurance is a voluntary scheme in Tasmania and the purchase of a policy is at the discretion of the Owner Builder in conjunction with a State run warranty scheme or private insurers.

It is however advisable best practice to have an Owner Builder Warranty Inspection done when selling a property within 6 years of the Certificate of Practical Completion being issued.

Whether you simply provide the potential purchaser with a copy of the inspection report as a form of disclosure during the sales process, or whether you go the additional step to take out a policy in their favour, an Owner Builder Inspection Report will facilitate confidence in the sale process.
