A building inspection is a detailed, non-invasive visual examination of a property's physical condition. Conducted by a qualified building inspector, the assessment covers the structural elements, exterior, interior, roof, subfloor, and major systems of the property. Building inspections are commonly performed before a property purchase, during construction, or as part of ongoing property management.
Scope of a Building Inspection
A standard building inspection follows nationally recognised guidelines that define the scope and limitations of the assessment. In the US, organisations like ASHI (American Society of Home Inspectors) and InterNACHI (International Association of Certified Home Inspectors) publish standards of practice; other countries have their own equivalent frameworks. The inspector examines the condition of foundations, walls, floors, ceilings, roofing, drainage, and external structures such as decks, carports, and retaining walls. The inspection is visual and non-invasive, meaning the inspector does not move furniture, lift carpets, or open sealed wall cavities.
Types of Building Inspections
Several types of building inspections serve different purposes. Pre-purchase inspections help buyers understand the condition of a property before committing to a purchase. Progress inspections monitor construction quality at key stages of a new build. Dilapidation reports document the existing condition of neighbouring properties before construction or demolition work begins. Handover inspections identify defects in newly built homes before the builder's warranty period expires.
What the Report Includes
A professional building inspection report describes the condition of each area inspected, identifies significant defects, and classifies them by severity. Major defects requiring urgent attention are distinguished from minor maintenance items. The report typically includes photographs, descriptions of findings, and recommendations for further specialist investigation where needed.
Choosing a Building Inspector
When selecting a building inspector, look for appropriate qualifications, professional indemnity insurance, and a track record of thorough, well-documented reports.
