Owner builder permit thresholds differ by state: NSW $10,000 alongside a development approval, Queensland $11,000 including GST, and WA $20,000 with $50,000 for a Class 10a building. Here is what each regulator requires, how often you can apply, and what…
Owner builder permit required where the work needs a development application or complying development certificate and is worth more than $10,000.
QBCC owner builder permit required for work over $11,000 including GST, or $27,500 for farm buildings.
Owner builder approval needed where a building permit applies and the work is over $20,000, or $50,000 for a Class 10a building.
The value threshold does the most work in this decision, and it is different in every state. New South Wales measures it against work that needs a development application. Queensland counts everything including GST above $11,000. Western Australia uses $20,000 but lifts it to $50,000 for a shed or carport. Get the threshold wrong and either you build without a permit you needed, or you pay for a permit you did not.
This guide covers what an owner builder permit is in each state, who issues it, what you have to hold before you can apply, how often you can get one, and what changes when you go to sell. The requirements are set out state by state, because almost nothing carries across a border.
NSW: when you need an owner builder permit
New South Wales asks two questions before it asks about value. The work has to need a development application or a complying development certificate, and it has to be worth more than $10,000. If the work needs neither approval, or falls at or under the threshold, you do not need a permit to do it yourself.
Value is measured on the work itself, and the NSW material states that the figure includes labour and materials. That catches owner builders who price the materials and forget the trades, and it is the reason a modest owner builder job can cross the threshold sooner than expected. If you are starting from scratch, the step-by-step guide to becoming an owner builder runs through the whole sequence, and the NSW owner builder course covers the units of competency the permit requires where the work is $20,000 or more.
What you have to hold before you apply
Eligibility turns on age, land, induction and value. You must be at least 18. You need to own or co-own the land, which includes a company share or a registered lease of three years or more. You need a valid White Card issued by SafeWork NSW, or an equivalent interstate authority, because construction induction sits on the eligibility list rather than being something a site asks for later. Ownership and the card apply at every value.
At $20,000 and above, the education requirement is the relevant units of competency, or approved equivalent qualifications and experience. It is not a general course you complete and then top up. The units are the requirement for that value band, and applicants regularly arrive having done something adjacent to them instead.
One permit every five years
New South Wales limits how often a permit can be issued. You can only hold one owner builder permit within any five-year period, unless the application and the earlier permit relate to the same land, or special circumstances apply. If you built five years ago on a different block, that history is part of the assessment.
Who issues it
The permit is granted by Building Commission NSW, and applications are lodged in person at a Service NSW centre. SafeWork NSW issues your White Card, but it has nothing to do with granting the permit. Treat them as two separate processes with two separate queues.
Queensland: the QBCC owner builder permit
Queensland works in one number: $11,000 including GST. If you want to build or supervise a project above that value on your own land, you need an owner builder permit from the QBCC. The same applies to company-owned land where you are a director, and to land you lease.
If the education side is what you are sorting out, the QBCC requires a course no more than five years old or a course exemption, and the Queensland owner builder course page sets out the course and how to enrol.
Farm buildings get a higher ceiling at $27,500. That is a specific allowance for farm structures, not a general uplift for rural blocks, so do not assume a shed on acreage falls under it.
The course, and how long it stays current
The QBCC owner builder course cannot be more than five years old at the time you apply. A course you completed six years ago for a renovation that never happened will not carry you now. In some circumstances the QBCC also expects an asbestos awareness certificate, so check the current list before you book anything.
If you already hold a qualification and want to rely on it, the alternative is a formal course exemption from the QBCC rather than simply lodging the older certificate.
One permit every six years
In most cases you can only have one owner builder permit every six years. There is a separate process if you have held a permit within that window, or if you have already finished the work. Both routes exist and both need to be checked before you fill in the application, because the wrong form wastes a month.
Western Australia: owner builder approval
Western Australia calls it an approval rather than a permit, and the test has two limbs. A building permit has to be required for the work, and the estimated value of the building work has to exceed $20,000. For a Class 10a building such as a shed, carport or private garage, the threshold is $50,000.
The value rule has a sting. You may not split building work into separate projects, each valued under the threshold, to avoid the licensing requirement. Two applications for half a house are not two small jobs.
Home indemnity insurance
All residential building work valued over $20,000, or $50,000 for a Class 10 building, must be covered by home indemnity insurance. Associated work such as a pergola, fence or swimming pool does not need it. If you are building as an owner builder and later sell, the insurance question follows you, which is covered further down.
What you have to hold
The knowledge requirement is the part people underestimate. At least one applicant has to hold a general construction induction card, and meet one knowledge route on top of it: a current or previous Building Practitioners registration in WA, registration as an architect, building surveyor or building engineer in WA, or WA-specific owner builder training completed within the previous 24 months.
Read that as two things, not one. The card is always required, and the knowledge route sits on top of it. An applicant who holds a building registration still needs the card. If the card is the part you still need, our guide to White Card requirements in NSW, QLD and WA covers who issues it and what evidence counts in each state. If the WA-specific training route is the one you are taking, the WA owner builder course page sets out what is involved.
Where the three states differ
| Question | NSW | Queensland | WA |
|---|---|---|---|
| Value threshold | More than $10,000, and the work must need a DA or CDC | More than $11,000 including GST; farm buildings up to $27,500 | More than $20,000; Class 10a buildings $50,000 |
| What it is called | Owner builder permit | Owner builder permit | Owner builder approval |
| Who issues it | Building Commission NSW, lodged at Service NSW | QBCC | Building Services Board, within the Department of Local Government, Industry Regulation and Safety |
| Course currency | Units of competency, or approved equivalent qualifications and experience, at $20,000 and above | Course no more than five years old, or an exemption | WA-specific training route, completed within 24 months |
| How often | One permit in any five-year period, with exceptions | One permit every six years in most cases | No building permit granted as an owner-builder in the last six years, with a waiver available; the six years runs from the permit grant |
| Construction induction | Valid White Card required | Work health and safety duty sits on the business | Card required, plus a knowledge route |
Selling a home you built yourself
In Western Australia, selling an owner-built dwelling within seven years of the date the building permit was granted is an offence with a penalty of $10,000, unless you obtain home indemnity insurance. That single rule catches more owner builders than any other, because the build ends and the clock keeps running.
Queensland works differently. Where the work was finished in the last six years, a disclosure notice has to be given to the buyer before the contract is signed. New South Wales applies its own arrangements on this point, so confirm the current position with the regulator before you list. If you are building with a sale in mind, work out the position before you start rather than after you have agreed a price.
What gets applications held up
Three things account for most of the delay, and none of them are about the building itself. The first is a course that has aged out. The second is not having the units of competency, or the approved equivalent qualifications and experience, where the work is $20,000 or more. The third is applying on a property with an earlier permit inside the restriction window, which surfaces during assessment rather than at lodgement.
None of those are fatal. All of them cost weeks, and all of them are cheaper to check before you pay for training than after.
Owner builder permit FAQs
Do I need an owner builder permit in all three states?
Each state sets its own threshold and its own test, and none of them carry across a border. NSW uses $10,000 alongside a development approval requirement, Queensland uses $11,000 including GST, and WA uses $20,000 with $50,000 for a Class 10a building.
How long is an owner builder course valid in Queensland?
The QBCC requires that the owner builder course is no more than five years old when you apply, or that you hold a course exemption.
How often can I get an owner builder permit?
NSW allows one permit in any five-year period unless the application and the earlier permit concern the same land or special circumstances apply. Queensland allows one permit every six years in most cases. In WA an owner builder approval is not granted where a building permit has been granted with you as owner-builder in the last six years, and the six years runs from that permit grant. A waiver application is available, and an approval issued but never used does not block a new one.
Can I split my project to stay under the threshold?
In WA, no. Splitting building work into separate projects to avoid the licensing requirement is prohibited. New South Wales measures the value of the work itself, and that figure includes labour and materials.
Do I need a White Card for an owner builder permit?
In NSW a valid White Card is part of the permit eligibility list. In WA a construction induction card is required of at least one applicant, alongside one knowledge route. In Queensland the card is not a QBCC permit criterion, but work health and safety duties still apply on site.
What is home indemnity insurance in Western Australia?
It is cover required for residential building work valued over $20,000, or over $50,000 for a Class 10 building, and it is not required for associated work such as a pergola, fence or swimming pool.
Can I sell a home I built as an owner builder?
In WA, selling an owner-built dwelling within seven years of the building permit being granted is an offence with a $10,000 penalty unless home indemnity insurance is obtained. Confirm the equivalent position in the state where the property is.
Who do I apply to in each state?
Building Commission NSW for a NSW permit, lodged in person at a Service NSW centre. The QBCC in Queensland. In Western Australia the Building Services Board grants the approval, within the Department of Local Government, Industry Regulation and Safety.
