NJ Standards of Practice

What is a Standards-Based Home Inspection?

A standards-based home inspection is a non-invasive, visual examination of the accessible areas of a residential property, which is designed to discover material defects within specific systems and components outlined within the “New Jersey Standards of Practice.”

  1. The home inspection is based on the observations made on the date of  the inspection, and not a prediction of future conditions.
  2. The home inspection will not reveal every issue that exists, or ever  could exist, but only those material defects observed on the date of the inspection.

A material defect is a specific issue found within a system or component that may have a significant, adverse impact on the value of the property, or that poses an unreasonable risk to people.  The fact that a system or component is near, at or beyond the end of its normal useful life is not, in itself, a material defect.

The resulting home inspection report documents these material defects within the specific  systems and components defined by these “Standards of Practice.” The inspection report may also include  additional comments and recommendations that the inspector feels are appropriate.

In New Jersey, all licensed home inspectors are requires to adhere to the “Standards of Practice” defined in the New Jersey Administrative Code at N.J.A.C. 13:40-15.16.   These New Jersey “Standards of Practice” are listed below:
