KIND OF OCCUPANCY STATUS
Living quarters are classified into dwelling houses and other occupied buildings
A dwelling is defined as a permanent building or a structurally separated part thereof,such as a detached house or an apartment of an apartment house that, by the way it has been built or altered, is intended for habitation by one household. A structurally separated part should be completely partitioned with fixed concrete or wooden walls.
A dwelling for habitation by one household must satisfy the following four requisites with respect to facilities.
(1) At least one room
(2) A sink for cooking
(3) A toilet
(Even if (2) and (3) are for joint use, they should be in a location where they can be used at any time and can be accessed without passing through other households.)
(4) An exclusive entrance (an entrance with direct access to the street or to a common space within the building)
Provided that they satisfy the above requisites, they are considered as dwellings even if they are not usually occupied.
Dwellings, which are not usually occupied, are referred to as dwellings without occupying households and are classified as follows:
Dwellings without occupying households
Dwellings with Temporary Occupants Only
Dwellings, which have no usual resident but, are used only in daytime or used by several persons on rotation.
Dwellings under Construction
Dwellings whose framework has been built, but construction has not been completed. Ferroconcrete buildings are included in this category if the outer walls have been built. A dwelling in which the internal finishing work has not yet been done but the door locks have already been fixed is classified as "vacant."
Dwellings under construction are regarded as complete dwellings if they are inhabited by a household.

(4) Hotels, motels, or inns built or arranged for tourists or persons staying temporarily.
(5) Other occupied buildings built temporarily and not converted for human habitation, such as hospitals, factories,workshops, offices, and construction camps.
