But in this guy's case, because he was renting out an unregistered AirBnB, and for a term of greater than 30 days, it was treated as a normal tenancy rather than as a short-term stay, and thus normal landlord-tenant laws apply.
Generally, one of the main rules of rental law is that tenants cannot be evicted for nonpayment of rent if there are habitability and compliance issues with the unit, which it appears there may be. (EDIT: also, it appears the unit itself was never permitted for occupancy, so he shouldn't even have been renting it out on AirBnB. This is probably why he didn't register it as a short-term rental.)
Basically, she's the tenant from hell...but he's also made a number of serious mistakes which let her take advantage of him in the first place.
