Welcome to the forum.
The requirements for lighting reduction controls comes from the energy conservation codes.
The 2009 IECC (International Energy Conservation Code) requires lighting controls that permit a occupant to reduce the lighting level in a room in a commercial occupancy by at least 50%. One of the exceptions to this requirement are rooms equipped with occupancy sensors. This requirement is not dependent on the number of occupants in the room.
Corridors, stairways, storage rooms, bathrooms, public lobbies and rooms with only 1 luminaire do not require lighting reduction controls.

According to the IECC, yes. Unless you install dual level lighting.

Occupancy sensors are cheap. Many janitors closet still utilize incandescent. Installing a sensor and setting it for 5 min time out is not a bad idea for those as the light tends to get left on ALL THE TIME by janitors.
It will save on energy and maintenance since the actual occupied time is so little that incandescent will actually last years.
