A Site Inspection, also known as a General Review of Construction, refers to a review of construction in progress by the design engineer or architect. It is intended to ensure that the as-built structure conforms to the permit drawings and specifications. At the end of each site visit, the engineer or architect produces a report that summarizes the findings. The Ontario Building Code (OBC) requires that a copy of the report is sent to the chief building official. The document forms part of the property record. A copy of the report is also sent to the property owner, the building contractor and other parties involved.

Typically performed at the behest of a homebuyer, a Home Inspection is an evaluation of an existing property. It involves visual observation and documentation of major components and systems, including the structure, exterior enclosure, interior finishes, HVAC system, electrical installations, insulation and other elements. The survey doesn’t document concealed deficiencies. It does not involve removing obstacles, making exploratory probing or using special equipment to access a hidden defect. The typical home inspection does not address environmental issues or Code compliance either.
