@Gwen386 The NYC laws are very hard to understand, possibly by design ,I can't say.
I just read them, and by my read you basically can't rent anything for less than 30 days. It would be insane and unsafe for both host and guest to rent a space where there isn't an ability to lock any of the inside doors, either for the guest to lock their own door or for the host to lock their part of the property. I will say, it is laws like this, where the only way to follow the law is to do something against all common sense, that are the problem.
I had thought, or maybe it was true at one time, that hosts who live on their property if it is less than a 4 family house, were exempted and could still host, but it doesn't look like that is the case.
