Inspection scope refers to the agreed-upon extent and limitations of a property inspection. It defines what the inspector will examine, how the examination will be conducted, and what falls outside the assessment. A clearly defined scope protects both the client, who understands what they are receiving, and the inspector, who has documented the boundaries of their professional responsibility. Misunderstandings about inspection scope are one of the most common sources of disputes in the inspection industry.
Standards of Practice
Professional inspection scope is typically governed by industry standards of practice published by recognised bodies. In the United States, ASHI and InterNACHI each publish comprehensive standards of practice for home inspections. Other countries have their own frameworks. These standards define the minimum requirements for a competent inspection, including which building systems must be examined, the methods to be used, and the limitations inherent in a visual, non-invasive assessment.
Common Scope Inclusions
A standard building inspection scope typically includes the structural elements (foundations, framing, roof structure), exterior (cladding, windows, doors), interior (walls, ceilings, floors), roof covering and drainage, subfloor where accessible, and basic assessment of plumbing, electrical, and moisture conditions. Each of these areas is assessed visually, without moving furniture, stored items, or fixed coverings.
Common Scope Exclusions
Items typically excluded from a standard inspection include concealed areas behind walls and under floors, asbestos and lead paint testing, engineering calculations, compliance certification, swimming pools, air conditioning systems, and pest inspection (unless specifically included). These exclusions should be clearly communicated to the client before the inspection begins.
Communicating Scope to Clients
Clear communication of inspection scope is essential for client satisfaction and risk management. The inspection agreement should outline the scope, standards applied, and any specific exclusions.
