Thank you, both!
I admit I'm a bit overwhelmed by the links you posted, aSwissInTheUS. I'm not sure I could take in everything.
There seemed to be a lot described about people who are NOT "angemeldet" (registered) . This person, however, IS angemeldet, but the rental contract will soon be over, and no alternative accommodation has been found. So they are not new, but already registered.
Perhaps my question ist: does the registration automatically cease if the rental contrat ends? I couldn't find anything that said it does end, especially if the ongoing intent is to stay in the gemeinde.
If, however, the registration does continue, then why would the organisation to which you linked, Mullhollander, even exist?
Does anyone know of a comparable organisation in Zurich, please?
Any friend offering a pseudo-registration runs the risk of their own situation's being conflated with that of the homeless friend. That can have outworkings with the landlord or the authorities, potentially negatively so.
Would there be any similar fist for receiving post only (no shared living space), no pseudo-Anmeldung? Can a friend B receive the mail of A, just as c/o, without this being anything to do with place of residence?
If A has a home, and B has a home, and A and B are each formally registered (angemeldet) in their own individual places, can B permanently give his/her postal address as c/o A... or are there negative consequences for A or for B?
