According to InterNACHI's Standards of Practice, which of the following is an inspector not required to determine the presence of?

In accordance with InterNACHI's Standards of Practice, inspectors are not required to determine the presence of lead-based paint. This is primarily due to the nature of lead-based paint being more historically prevalent in older homes rather than in homes constructed after the 1978 ban on its use. Lead-based paint inspections typically require specialized training and lead-specific tests which fall outside the general scope of a standard home inspection.

In comparison, inspectors are expected to assess other aspects such as whether asbestos, radon, and mold issues are present, even though they may not carry out intrusive tests themselves. These substances pose recognized health risks, and inspectors should be vigilant in identifying conditions that may suggest their presence or recommend further evaluation, thus establishing the appropriate action for clients. The distinction lies in the nature of the requirement: while certain safety hazards need to be flagged, lead-based paint assessments are specifically detailed in separate regulations.
