usage
The intended purpose of a place, structure, property, or other object at a given time, including while it is vacant.
The usage of any place, property, structure, or other object is the general purpose for which it is intended at any given time. If a place is vacant or unused, the intended usage still applies to it.
Usages are distinguished from amenities, which are subordinate to the usages they belong to (for example a swimming pool in a hotel belongs to the hotel usage, and should not be identified as a usage itself).
Intended use is distinct from the object's physical form and from its momentary occupancy. A vacant place retains its intended use, and a subordinate amenity remains associated with the usage it supports.
