Many buyers searching for a building inspector in Queensland assume that any QBCC-licensed inspector can inspect both established homes and new builds to the same standard. This assumption is understandable — both are called building inspections, both are conducted by QBCC-licensed practitioners, and both produce a report. But the disciplines are fundamentally different, and choosing an inspector who specialises in one when you need the other produces a meaningfully inferior outcome.
What a Pre-Purchase Inspection Is
A pre-purchase inspection is conducted on an established home — one that has been occupied for some years or decades. The purpose is to identify visible defects, signs of deterioration, evidence of historical water damage, structural movement, and pest damage before the buyer commits to purchase.
The inspector works from what is visible and accessible. They assess a building whose history is unknown — they are looking for evidence of problems that have already manifested, not for compliance with construction standards applied when the building was new.
The governing standard for pre-purchase inspections is AS 4349.1 — a standard specifically written for the inspection of existing dwellings. The inspector is comparing the home against the condition you would reasonably expect of a building of its age and type.
What a New Build PCI Is
A new build PCI is conducted on a home that has just been completed — typically within days of the builder's practical completion notice. The home is brand new. It has never been occupied. The purpose is to assess whether it was built correctly — not whether it shows signs of deterioration.
The governing standard for new build PCIs is the QBCC Standards and Tolerances, the National Construction Code, and the approved building plans. The inspector is not looking for visible signs of deterioration — they are measuring. They measure shower membrane height against the 1800mm minimum. They assess site drainage fall against the 50mm per metre minimum gradient. They check roof fixing patterns against the wind classification specification for each lot.
This requires current, specific knowledge of Queensland's construction standards — knowledge that is built through repeated attendance at new home inspections, not through pre-purchase inspection of established properties.
Where the Difference Shows Up
An inspector who primarily conducts pre-purchase inspections will check for visible waterproofing failure — staining, mould, moisture damage. They may miss a non-compliant membrane height of 1400mm because on an established home, what matters is whether the waterproofing is currently failing, not whether it was installed to the correct height when it was new.
An inspector who specialises in new build PCIs checks the height of every shower membrane on every wall — because they know that non-compliant height is the most common defect found on new builds and they know that identifying it before tiling is the only cost-effective time to fix it.
The same pattern applies to roof fixing, structural bracing, termite management systems, and every other compliance-specific element that a new build PCI must assess.

Book an InspectionWhy VG Inspect Inspects New Builds Only
VG Inspect inspects newly constructed homes exclusively. We do not conduct pre-purchase inspections on established properties. This is a deliberate choice — it means every inspection we conduct is in the context we are specifically experienced in, and every report we produce is formatted for the purpose of requiring a builder to rectify non-compliance.
If you need a pre-purchase inspection on an established home, we are not the right choice. If you need a PCI or stage inspection on a new home in SEQ, we are. QBCC licence 1318443.
