Compliments InterNACHI.
468.8323 Home inspection report. Upon completion of each home inspection for compensation, the home inspector shall provide a written report prepared for the client.
(1) The home inspector shall report:
(a) on those systems and components inspected that, in the
professional opinion of the inspector, are significantly deficient or
are near the end of their service lives;
(b) if self-evident, a reason why the system or component reported
under paragraph (a) is significantly deficient or near the end of its
service life.
(For a comparison of service life expectancies in other areas of the U.S., see The Estimated Life Expectancy Chart for Homes.) Consumers and inspectors and other professionals advising their clients should note that these life expectancies have been determined through research and testing based on regular recommended maintenance and conditions of normal wear and tear, and not extreme weather (or other) conditions, neglect, over-use or abuse. Therefore, they should be used as guidelines only, and not relied upon as guarantees or warranties.
