Owner-builder questions for New South Wales (NSW)
Do I need a permit to owner-build in NSW?
Yes. If the work is valued over $10,000, you need an Owner-Builder Permit from NSW Fair Trading. You'll also need to complete an approved Owner-Builder Course and hold a White Card before applying.
How much does it cost to owner-build in NSW?
Typical NSW owner-builds cost $1,800–$3,500 per square metre depending on your area (Sydney metro is higher than regional), finishes, and build complexity. A 200m² home might cost $400K–$700K as an owner-builder vs $550K–$900K+ through a licensed builder.
What inspections are mandatory for owner-builders in NSW?
NSW requires inspections at key hold points: site set-out, footings, slab, frame, waterproofing, and final (Occupation Certificate). These are conducted by your PCA — either a private certifier or council. Missing an inspection can mean rework at your cost.
Can I sell my owner-built home in NSW?
Yes, but if you sell within 6 years of completion you must provide Home Building Compensation Fund (HBCF) insurance to the buyer and disclose the owner-builder status. This is a legal requirement under the Home Building Act 1989 (NSW).
What insurance do I need as an owner-builder in NSW?
Workers compensation insurance if you have anyone working on site (even unpaid helpers in some cases), public liability insurance (strongly recommended), and HBCF cover if you intend to sell within 6 years. Always confirm with NSW Fair Trading and your insurer.
