"She added that inspectors need a substantial amount of evidence to issue a violation on an illegal vacation rental, such as having a guest admit that they were a tenant for fewer than 30 days."

Nonsense, all the DPP department, or anyone else for that matter, needs for evidence to bust any illegal vacation property is go online to AirBnB or any other short term rental agency is actually book a rental and show up with a audio & video recording device to record the transaction taking place and hopefully record the property owner/manager for further proof that might be needed in court and to issue a citation on the spot. Very fast and easy 2 minute bust, it's no different than a drug or prostitution bust.
