ASHI® stands for American Society of Home Inspectors.  It is the most widely recognized national organization for Home Inspectors.  Prior to licensing in Arizona,  ASHI® set the standards for home inspections.  In fact, the Arizona Board of Technical Registration adopted ASHI® Standards as the state guidelines for Arizona Home Inspectors.

An ASHI® Member must meet certain experience requirements, in addition to passing a written test.  ASHI® Members are also required to observe the ASHI® Standards of Practice and Code of Ethics.  ASHI® is still the standard in most places, with or without licensing requirements.  Most Real Estate Agents won't even use a home inspector that is not an ASHI® Member or Candidate.
