The owner's local agent shall inspect all registered properties, and all properties
subject to registration, on a monthly basis to determine if the property is abandoned,
vacant, or shows evidence of vacancy, or evidence of unlawful occupation (i.e, squatters),
and to ensure that the property is in compliance with this article and other laws
and regulations. If the inspection reveals information different than what is contained
on the registry, the owner shall update the registry within ten days of the inspection.
