What is required for an RPR to be considered valid?

For a residential property report (RPR) to be deemed valid, it must include both the surveyor's original signature and the permit stamp. The original signature indicates that a qualified professional has authenticated the RPR, verifying that it has been prepared following the necessary standards and regulations. Additionally, the permit stamp signifies that the surveyor has followed the proper procedures and has the authority to produce the report. This combination ensures that the document is both credible and recognized by relevant authorities, which is crucial for legal and compliance purposes in real estate transactions.

Other options may suggest incomplete documentation or lack the requisite professional validation, making them insufficient for establishing the validity of the RPR. Having merely a stamp or a signature alone does not provide the assurance of compliance and professional endorsement necessary for the report to be functionally reliable.
