How to Read a Building Inspection Report (Australia 2026)
A building inspection report is one of the most important documents you'll receive during a property purchase - yet most buyers barely skim it. Here's how to read yours like a pro.
## Start With the Summary
Most inspection reports include an executive summary in the first few pages. This is your starting point. Look for anything rated as "Major" or "Significant" - these are the findings that could cost thousands to fix.
## Understand the Rating System
Most Australian inspectors use a severity scale:
- **Minor** - Cosmetic or maintenance items. Budget $200–$1,000 each.
- **Moderate** - Functional issues that need attention within 12 months. Budget $1,000–$5,000.
- **Major** - Significant defects requiring prompt professional attention. Budget $5,000–$20,000+.
- **Critical** - Safety hazards or potential deal-breakers. Get specialist advice immediately.
## Red Flags to Watch For
**Structural cracks** - Hairline cracks in plaster are usually cosmetic. Diagonal cracks in brickwork wider than 5mm, or cracks that run through multiple courses, may indicate foundation movement.
**Rising damp** - Look for mentions of "efflorescence" (white salt deposits on walls), "subfloor ventilation" issues, or moisture readings above normal. Rising damp treatment costs $3,000–$10,000.
**Roof condition** - Roof replacement is one of the most expensive repairs ($10,000–$25,000 for Colorbond). Pay attention to mentions of "degraded pointing," "broken tiles," or "end of serviceable life."
**Electrical** - Outdated switchboards without safety switches (RCDs) are both a safety hazard and a compliance issue. Budget $1,500–$4,000 for a full switchboard upgrade.
## What to Do Next
If your report contains Major or Critical findings, you have several options:
1. **Renegotiate the price** - Use the repair cost estimates as leverage.
2. **Request the seller fix issues** before settlement.
3. **Get specialist reports** - A building inspector is a generalist. For structural, electrical, or pest issues, get a specialist quote.
4. **Walk away** - Sometimes the smartest move is not buying.
