Home Inspection Standards of Practice
The Standards of Practice domain tests whether you understand the minimum scope, limitations, and reporting duties of a home inspection. The exam expects you to distinguish what an inspector must observe from what is explicitly excluded, and to use language that is accurate rather than absolute.
Scope and limitations
A home inspection is a visual, non-invasive, readily accessible inspection of systems and components using normal operating controls. The SOP is a minimum standard, not a maximum. Inspectors are not required to move stored items, open finished walls, conduct destructive testing, or inspect concealed spaces. They must describe the systems inspected, identify material defects observed, and note items needing further evaluation.
Reporting language
Reports should say “no material defects observed” rather than “no defects,” and should state limitations plainly. If an area was inaccessible, document it. Recommending a specialist is appropriate when a condition is visible but its cause or remedy is outside the SOP.
Worked example
A buyer asks why the report did not mention mold behind finished drywall. The inspector explains that the SOP is visual and non-invasive; the drywall was intact and no moisture staining was visible; mold testing is outside the scope. The report should document the limitation and recommend environmental testing if the client wants it. Reasoning: absence of a finding is not a warranty, and concealed conditions are excluded.
Traps
Treating the SOP as a checklist maximum; implying code compliance; writing “no defects” instead of “no material defects observed”; failing to document inaccessible areas or the inspection method.
