According to the Queensland Building and Construction Commission, on "20 June 2014, the Queensland Building and Construction Board made the Rectification of Building Work Policy which replaced the 6 month building inspection report.
If your building contractor has carried out defective building work they may be required to rectify that work irrespective of whether they did or did not comply with the contracted plans and specifications for your work.
In seeking the assistance of the Queensland Building and Construction Commission (QBCC) to "direct a building contractor to rectify defective building work, you must lodge a formal complaint with the QBCC as soon as possible, but no later than within 12 months of becoming aware of the defects.
And most importantly for you, the QBCC will then direct your building contractor to rectify if non-structural defective building work is within 12 months of the building work being completed as opposed to 6 months previously - this means you will need an 11 month warranty inspection to ensure you don't miss the 12 month cut off.
The timeframe for rectification of structural defective building work continues to be within 6 years and 3 months of the building work being completed.
