    2.2 Inspectors shall:
    1. inspect :
      1. readily accessible systems and components of homes listed in these Standards of Practice.
      2. installed systems and components of homes listed in these Standards of Practice.

      1. 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.
      2. a reason why, if not self-evident, the system or component is significantly deficient or near the end of its service life.
      3. the inspector's recommendations to correct or monitor the reported deficiency.
      4. 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.

    2.3 These Standards of Practice are not intended to limit inspectors from:
    1. including other inspection services, systems or components in addition to those required by these Standards of Practice.
    2. specifying repairs, provided the inspector is appropriately qualified and willing to do so.
