The American Society of Home Inspectors® (ASHI) is the oldest and most widely recognized non-profit professional association for independent home inspectors. ASHI's "Standards of Practice" serve as the home inspector's performance guideline, and are universally recognized and accepted by professional and government authorities. Copies of the Standards are available free from ASHI.

ASHI's professional Code of Ethics prohibits members from engaging in conflict of interest activities, which may compromise their objectivity. This is the assurance to the consumer that the inspector will not, for example, use the inspection to solicit or refer repair work.

ASHI sponsors continuing education, technical seminars and workshops and serves the public interest by providing accurate and helpful consumer information to home buyers on home purchasing and home maintenance.
