In a fictional setting:
* In a mansion or large house: They might have a dedicated room or a shared quarters with other servants.
* In a hotel: They often have a separate living space, usually on-site, but could also be off-site with a commute.
In a real-life setting:
* Live-in maids: They usually reside in the house they work in, often having a separate room or shared quarters.
* Non-live-in maids: They have their own residences and commute to work. This is more common in modern times.
It's important to remember that "maids" are people with their own lives and homes, just like anyone else. Their living arrangements are as diverse as the people who work as maids.
