The owner wants to know if this is the owner's property, can he say so?

First, the property company has the owner's file, which can find out who the owner of the property is.

Second: the head of household you mentioned is the head of household in the household registration book, and the property company will not register the head of household for individual families.

Third: the property company has no right to disclose the privacy of others unless it is inquired by the public security organ.
