Since State of California Legislation does not currently licensing of the property inspection profession, most reputable inspectors follow standards of practice set out by professional associations such as the International Association of Certified Home Inspectors or similar organizations.

Aston Property Inspection is a member of the International Association of Certified Home Inspectors (InterNACHI), formally known as the National Association of Certified Home Inspectors (NACHI), but now incorporating Canada and several other countries in addition to its core membership within the United States.  Visit the InterNACHI website here .

InterNACHI members operate according to strict  Standards of Practice.  InterNACHI promotes exceptionally high standards of practice among its members.  The Standards of Practice are slightly different for Residential buildings (Home Inspections) and Commercial properties.  In addition, all members of InterNACHI abide by a strict Code of Ethics, a copy of which is available here.
