All of the following are considered optional report items EXCEPT?

The description of components is considered a mandatory part of the home inspection report rather than an optional one. This section provides essential information about the various systems and components in the property being inspected, such as the roof, plumbing, electrical systems, and HVAC. This detailed documentation helps to inform the client about the current condition of these components, any potential issues, and maintenance needs.

In contrast, items like the contract, scope of work, and limitations may vary from one inspection to another and often depend on the specific agreement between the inspector and the client. These documents are not universally required and may be included or omitted based on the particular circumstances of the inspection. Thus, they are considered optional report items.
