Which of the following items is NOT required on a property disclosure?

The presence of an underground storage tank and issues like plumbing problems or termite infestations are commonly required to be disclosed because they affect the safety, usability, and value of the property. Such disclosures help buyers make informed decisions by understanding potential issues that could affect their living conditions or incur additional costs for repairs or remediation.

On the other hand, the occurrence of a felony on the property, while it may impact certain perceptions, does not typically fall within the mandatory disclosures outlined by Virginia law. Disclosure laws primarily focus on physical defects and risks related to property condition rather than criminal activity. Therefore, while it is essential for sellers to communicate any issues that could affect the safety or integrity of the property, the occurrence of a felony is generally considered personal information that does not need to be disclosed under property disclosure requirements. This distinction clarifies why the correct answer is the occurrence of a felony on site, which is not mandated for disclosure.
