With regard to the supportive housing I am familiar with, each resident has their own apartment, including a private kitchen and private bathroom. The residents are allowed to have a pet.

There is also one common room with a kitchen, TV, one large seating area (tables and chairs), one section with sofas and comfortable chairs, and two bathrooms. The common room is used for meetings, gatherings, weekly community dinners, and just a place to hang out.

The supportive housing complex is very pleasant and pretty. Clean, and a place people would want to live in.

As for staff coming into people's apartments, there are yearly inspections to make sure everything is working properly in the apartment. But that is usually the case with any apartments and rentals.

The situation you've described, shared bathrooms and common kitchen, sounds more like a group home setting. I don't know where you're located, though...it's possible supportive housing and group homes are somewhat different in different places.

I know several people who do, or have, lived in a group home. They can be really nice, too, especially if the staff is a good one. From what I've heard privacy is respected. Group homes are generally more regulated (with curfews, for example). They are communal (shared bathrooms, shared kitchen, common TV room, etc.).
