Building or buying a property is one of the biggest financial commitments most people make. Whether you’re a homeowner, investor, or developer, ensuring your building is safe, compliant, and free from hidden defects is critical. That’s where building inspections come in.
In this ultimate guide, we’ll cover everything you need to know about building inspections in Perth, including what they involve, why they matter, and how to choose the right inspection service.
What Is a Building Inspection?
A building inspection is a thorough assessment of a property’s condition and compliance with Australian building standards. An independent inspector examines the structure, finishes, and systems to identify defects, safety concerns, and potential risks.
Depending on the stage of your project or purchase, inspections can cover:
- Pre-purchase inspections – for buyers before settlement
- Construction stage inspections – during key phases of the build
- Practical completion / handover inspections – before making final payment to the builder
- Defect liability period inspections – identifying issues within the warranty period
Why Are Building Inspections Important?
- Identify hidden defects – Many structural or safety issues aren’t visible to an untrained eye.
- Ensure compliance – Inspections confirm that construction meets WA Building Codes and Australian Standards.
- Save money – Fixing problems early costs far less than repairing major defects later.
- Protect your investment – Inspections safeguard both property buyers and developers.
- Peace of mind – You know your property is safe, secure, and built to standard.
When Should You Book a Building Inspection?
For maximum protection, inspections should be scheduled at critical stages:
- Pre-purchase – Before buying any home, new or old.
- Slab / foundation stage – Ensures groundworks and slab are correct.
- Framing stage – Checks structural framing before walls and roofing go on.
- Lock-up stage – Verifies doors, windows, roofing, and external works.
- Pre-handover (PCI) – A full inspection before you pay the final invoice.
- Defect liability period – Usually 6–12 months post-build, to catch issues under warranty.
What Do Inspectors Look For?
A professional building inspector examines a wide range of elements, including:
- Structural integrity – foundations, framing, load-bearing walls
- Roofing & ceilings – leaks, defects, or poor installation
- Plumbing & drainage – leaks, water pressure, moisture issues
- Electrical safety – compliance of visible wiring and fittings
- Floors & finishes – uneven surfaces, cracking, poor workmanship
- Compliance checks – ensuring work meets WA and Australian Standards
Perth-Specific Building Challenges
In Western Australia, there are unique factors that make inspections even more important:
- Expansive clay soils that can cause cracking if not properly managed
- Seasonal weather conditions (heavy rains, high winds) impacting foundations and roofing
- Termite risks in certain areas requiring thorough pest checks
- Strict WA building compliance requirements enforced by local councils
How Much Do Building Inspections Cost in Perth?
Costs vary depending on the type and size of property, but generally:
- Pre-purchase inspections: $400 – $700
- Construction stage inspections: $300 – $600 per stage
- Practical completion inspections: $500 – $800
While this is an additional cost, it’s a small price compared to the thousands you could spend fixing hidden defects later.
Choosing the Right Building Inspector in Perth
Not all inspectors are equal. Look for:
- Independence – Ensure the inspector is not tied to your builder.
- Qualifications & licensing – Registered builders or engineers with inspection expertise.
- Experience in WA construction – Knowledge of local soils, weather, and standards.
- Clear reporting – Detailed, easy-to-understand inspection reports with photos.
- Professional reputation – Check reviews and client feedback.
