Queensland's domestic building legislation provides new home owners with layered warranty protection. Understanding exactly what each layer covers, for how long, and how to enforce it is essential for every new home buyer.
Layer 1 — The 12-Month Defect Liability Period
The defect liability period runs for 12 months from practical completion — the date you accepted the keys. During this period, your builder is legally obligated to rectify defects notified in writing. This covers workmanship defects and items not built in accordance with the approved plans, the QBCC Standards and Tolerances, or Australian Standards.
The defect liability period is your most powerful protection. It is free to use, requires no escalation to QBCC in most cases, and applies to a broad range of defects including cosmetic items that exceed QBCC tolerance thresholds.
Book your warranty inspection at the 10-month mark. This gives you 10 months of occupancy for latent defects to manifest and two months to notify the builder and require rectification before the period expires.
Layer 2 — The 6-Year 6-Month Structural Warranty
Beyond the 12-month defect liability period, Queensland builders are liable for structural defects for six years and six months from practical completion. Structural defects are those that affect the structural integrity of the building — cracking in structural elements, foundation movement, or defects in load-bearing components.
The structural warranty covers a narrower range of items than the 12-month period but applies for a much longer timeframe. Homes completed in 2022 are still within their structural warranty in 2028.
Layer 3 — QBCC Home Warranty Insurance
All residential building contracts over $3,300 in Queensland require the builder to hold QBCC Home Warranty Insurance. This insurance activates if your builder becomes insolvent, dies, disappears, or has their licence cancelled before completing rectification.
The insurance provides a safety net for situations where the builder can no longer fulfill their warranty obligations — not for situations where they simply refuse to.
