Which of the following is a component of a lead-based paint inspection?

Investigating the age and history of the dwelling is a crucial component of a lead-based paint inspection because lead-based paint was commonly used in homes built before 1978, the year the EPA banned its residential use. Knowing the age of the property helps assess the likelihood that lead-based paint is present. Additionally, understanding the history of the dwelling, such as any renovations or repairs that may have involved lead paint, can further inform risk assessors about potential lead hazards. This information is vital for determining the appropriate testing and remediation steps, making it an essential part of the inspection process.

The other options do not directly contribute to the lead-based paint inspection. Interviewing previous occupants about allergies might provide some health information but does not specifically assess lead presence. Estimating property value relates to real estate but is not relevant for identifying lead hazards. Performing a full structural analysis focuses on structural integrity rather than lead-related concerns, making it outside the scope of lead inspections.
