An occupied space or place is one that has people or things in it. This can mean an office building with employees working there.
When we talk about something being occupied, usually we're referring to a place like a house, apartment, office, or even a country where people are living and working. For example, if someone says their home is occupied by relatives for the summer, they mean that family members have moved in to stay for a while. In politics, an occupied territory might be one that's controlled by another country's government. If you're planning a move, it's also common to say a house is occupied until it sells and someone new moves in.
Reserved, engaged.
Example: The stall on the left is occupied.
(of time) To take or use.
