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.
