What do you need to provide for a live-in caretaker?

I am considering hiring a live-in caretaker for my father. I am having trouble finding much information about what sort of living environment you need to provide for the caretaker. Any guidance would be appreciated.

To provide some context, my father's house is not in good repair. I would not want to live there but my standards may not be the same as other people's. It is not a "Hoarders" situation but he does not do housework so all the surfaces are cluttered and there's not a lot of pleasant living space. The oven and stove do not work. He has a microwave and a refrigerator. There is no dishwasher, he uses paper plates and disposable utensils. I don't know if he has any dishes or cookware. He has a washing machine but no dryer. There are 3 bedrooms and 1.5 functional bathrooms. The furniture is 1960's vintage but not in a good way. The heating and A/C are fine.
