Standard of Practice

The Standards of Practice are a set of guidelines for home inspectors to follow in the performance of their inspections.

The Standards of Practice and Code of Ethics are recognized by many related professionals as the definitive standard for professional performance in the industry.

Home Inspections performed to these Standards of Practice are intended to provide the client with information regarding the condition of the systems and components of the home as inspected at the time of the Home Inspection.
  2. The Inspector shall inspect readily accessible and installed systems and components of homes listed in these Standards of Practice.
  3. The Inspector shall report on those systems and components inspected which, in the professional opinion of the inspector, are significantly deficient or are near the end of their service lives.
  4. The Inspector shall report a reason why, if not self-evident, the system or component is significantly deficient or near the end of its service life.
  5. The Inspector shall make recommendations (if he or she chooses to) to correct or monitor the reported deficiency.
  6. The Inspector shall report on any systems and components designated for inspection in these Standards of Practice which were present at the time of the Home Inspection but were not inspected and a reason they were not inspected.
