Occupancy is living in or using premises or property as a tenant or owner. This includes someone who lives in or uses abandoned property with the intention of acquiring ownership. Occupancy in building construction and building codes is the use or intended use of a building or part thereof for the shelter or support of persons, animals or property. A closely-related meaning is the number of units in such a building that are rented or leased, or otherwise in-use. The lack of occupancy in this sense is a vacancy. Occupancy can also mean the number of persons using an undivided space, such as a meeting room, ballroom, auditorium, or stadium.
