Certified by the International Association of Certified Home Inspectors

 

1. Definitions and Scope

1.1.  A general home inspection is a non-invasive,  visual examination of the accessible areas of a residential property (as  delineated below), performed for a fee, which is designed to identify defects  within specific systems and components defined by these Standards that are both  observed and deemed material by the inspector.  The scope of work may be  modified by the Client and Inspector prior to the inspection process.

  1. The general home inspection is based on the observations made on the date of  the inspection, and not a prediction of future conditions.
  2. The general home inspection will not reveal every issue that exists or ever  could exist, but only those material defects observed on the date of the  inspection.

1.2.  A material defect is a specific issue with a  system or component of a residential property that may have a significant,  adverse impact on the value of the property, or that poses an unreasonable risk  to people.  The fact that a system or component is near, at or beyond the  end of its normal useful life is not, in itself, a material defect.

1.3.  A general home inspection report shall  identify, in written format, defects within specific systems and components  defined by these Standards that are both observed and deemed material by the  inspector.  Inspection reports may include additional comments and  recommendations.

  5. An inspection does not determine the market value of the property or its  marketability.
  6. An inspection does not determine the insurability of the  property.
  7. An inspection does not determine the advisability or inadvisability of the  purchase of the inspected property.
  8. An inspection does not determine the life expectancy of the property or any  components or systems therein.
  9. An inspection does not include items not permanently installed.
