2. Number of rooms

20 Number of rooms (Question II) [p. 35]
1. A room shall be understood as:a part of the dwelling which is additionally separated from other rooms with walls, having direct lighting, and characterized by the useful floor space no smaller than 4 meters squared.
Direct lighting shall be understood as a window or glazed doors located on the outer side of the building and therefore granting the view of the yard, street, garden, porch, etc.
If there is no direct lighting in the habitable space then, even if it has an internal window (skylight) connected with other rooms or the hall, such a space shall not be considered a room.
2. All the rooms in the dwelling must be registered, so both those occupied, partially used, and unoccupied ones. What is more, rooms used only for vocation-related purposes (consulting rooms, shoemaker's workshops, tailoring rooms) must be included in this category as well, if only they are located within the dwelling. However, if a given room, which is used strictly for the vocation-related purposes has a separate entrance from the hall, yard, or other freely accessible part of the room, then it shall not be considered a separate room, even it is a part of the dwelling. Such a space shall also not be included while calculating total floor space of the dwelling (see 19, point 4).
3. Habitable spaces shall be divided in the following manner:

Such spaces as multifunctional rooms (serving education, relaxation, food consumption, and rest-related purposes), bedrooms, dining rooms, kitchens, kids' rooms, as well as all the rooms used for vocational purposes (offices, workshops) and those utilized as accommodation for visitors and patients shall be indicated in point a.
In point b, kitchens with windows of the overall floor space of 4 m2 or more shall be indicated that is kitchens that may be qualified as typical rooms.
Kitchens without windows shall not fall into this category, even if their total floor space exceed 4 m2 , as well as kitchens with windows, the floor space of which is lower than 4 m2. The said spaces shall be indicated in point c.
One-room dwellings which also serve the role of kitchens should be classified in accordance with the opinion of the lodger. If the latter has some difficulties with classifying such a room, then it should be assumed that a habitable space equipped with a coal or gas-powered furnace (connected to the bottle or the network) shall be considered a kitchen and a space in which a small electric oven or moveable cooker is stored shall be classified as a room.
Point c other rooms has been implemented with other (furnished) habitable spaces that are not currently used for occupational purposes in mind. Such a specification concerns especially:

The latter are characteristic for rural areas but such cases may be encountered in towns and cities as well. If the lodgers not consider them to be proper rooms, then they should not be indicated while filling in the main form.
Rooms that are so devastated that they cannot be used anymore shall not be indicated (as well as their floor space shall not be calculated see: question 19, point 4).
Rooms that are taken advantage of to store food products shall not be mistaken with typical pantries which are built with storage of large quantities of food in mind and are larger, as well as have bigger windows. Typical pantries are not rooms and shall not be indicated in the form. Nevertheless, they shall be included while calculating the total useful floor space.
4. Such spaces as halls, bathrooms, toilets, verandas, porches, typical pantries, sheds and chambers are not rooms regardless of their floor space and type of lighting.
