1. Definitions and
Scope
1.1. A Home inspection is a non-invasive visual
examination of a residential dwelling, performed for a fee, which is designed to
identify observed material defects within specific components of said dwelling.
Components may include any combination of mechanical, structural, electrical,
plumbing, or other essential systems or portions of the home, as identified and
agreed to by the Client and Inspector, prior to or during the inspection
process.
I. A home inspection is intended to assist in
evaluation of the overall condition of the dwelling. The inspection is based on
observation of the visible and apparent condition of the structure and its
components on the date of the inspection and not the determination of future
conditions.
II. A home inspection will not reveal every
problem that exists or ever could exist, but only those material defects
observed on the day of the inspection.
1.2. A Material defect is a problem with a
residential real property or any portion of it that would have a significant
adverse impact on the value of the property or that involves an unreasonable
risk to people on the property. The fact that a structural element, system or
subsystem is near, at or beyond the end of the normal useful life of such a
structural element, system or subsystem is not by itself a material defect.
1.3. An Inspection report shall describe and
identify in written format the inspected systems, structures, and components of
the dwelling and shall identify material defects observed. Inspection reports
may contain recommendations regarding conditions reported or recommendations for
correction, monitoring or further evaluation by professionals.
