Final answer:
The Standard of Practice dictates what a home inspector is required to report on, usually focusing on essential systems. Optional systems are not typically included unless prearranged with the client. Knowledgeable inspectors can, however, report on present optional systems if agreed upon within the service contract.
Step-by-step explanation:
The Standard of Practice for inspectors often outlines the scope of an inspection, detailing which components of a property are required to be inspected and which are optional. The specific standard will vary by region and organization but typically, home inspections focus on the primary systems that are essential for the operation of a home such as electrical, plumbing, and structural components.
When it comes to optional systems, the inspector is generally not required to report on these as they fall outside the scope of a standard home inspection. However, if optional systems are present and the inspector is knowledgeable in those areas, or if the service has been agreed upon as part of the inspection contract, then the inspector may report on them. Optional systems could include things such as swimming pools, lawn sprinkler systems, outbuildings, or other non-essential features. Inspectors might also report on the presence of optional systems to note that they were not inspected.
In summary, while inspectors must report on all systems that fall within the Standard of Practice, reporting on optional systems is not a requirement unless specifically included in the service agreement.
