It sounds to me that the owner must be badly represented. The reason he can't evict appears to be that the accomodation isn't considered suitable to let, because it has an "illegal shower". As a consequence he is denied access to remedy other causes of problems with the property (damp penetration). I'm not American, and definitely not from CA; and I'm certainly not any kind of lawyer. It seems to me that the Department of Building and Safety must be guilty of gross maladministration, and the landlord should be able to sue for compensation and punitive damages. It seems obvious. Meanwhile, I detest AirBnB. My neighbour is a non-resident AirBnB host.
