ASHI STANDARD OF PROFESSIONAL PRACTICE FOR HOME INSPECTIONS 1. INTRODUCTION 1.1 This ASHI Standard of Professional Practice for Home Inspections (Standard) defines the scope of home inspections performed by professional inspectors who use this Standard. Reports created using this Standard provide clients with information about the condition of the inspected systems and components at the time of the inspection. Home inspections are intended to discover significant deficiencies. These inspections do not discover every deficiency that may be present and these reports do not provide a complete list of all deficiencies. 1.2 Home inspections performed using this Standard require unique knowledge and skills that are usually acquired through education and experience. Only professional inspectors should perform home inspections using this Standard. 1.3 Words printed in italics are defined in Section 13. These definitions are essential to understanding and using this Standard. 1.4 Inspectors shall comply with the requirements of this Standard and any applicable government regulation of home inspections. 2. SCOPE 2.1 Inspectors shall adhere to the ASHI Code of Ethics for the Home Inspection Profession. 2.2 Inspectors shall inspect readily accessible and visually observable installed systems and components designated in Sections 3 through 11 by using normal operating controls and by opening easily opened access panels. Inspectors may: A. include other services and other systems and components in addition to those required in this Standard; and/or B. exclude systems and components required in Sections 3 through 11 if requested or agreed to by the client.
