What is one of the requirements before performing a PCAD?

To perform a PCAD (Post-Construction Assessment for Deteriorating Lead), a letter of compliance is a crucial requirement. This letter signifies that the work related to addressing lead hazards has been completed according to the regulations and standards set forth by local and federal authorities. It indicates that the property is compliant with applicable lead-safe practices, which is vital for ensuring that the environment is safe for occupancy and that any risks associated with lead exposure have been adequately mitigated.

The presence of a letter of compliance ensures that the preceding actions taken to remediate or manage lead hazards were conducted to meet necessary guidelines, thereby establishing a foundation for conducting a PCAD. This requirement is in place to ensure that lead-related risks have been addressed prior to further assessment, thus protecting the health and safety of occupants, particularly vulnerable populations like children.

In the context of the other choices, while dust sample results and inspection reports are important documents in the overall process of lead management, they are not specifically required before conducting a PCAD. Similarly, a waiver from local authorities may be relevant in certain contexts, but the primary focus of the PCAD is ensuring that remediation efforts have complied with all necessary regulations, which is what the letter of compliance certifies.
