Not counting bathrooms, kitchens, accessory areas and associated structures, such as basements, attics, garages, etc. A room is a space that receives air and light directly from outdoors and that is large enough to hold a bed and leave sufficient space to move around.

Number of rooms _ _

- Rooms with independent access but functionally attached to the dwelling and being used by the family should be considered part of the same dwelling;
- Large rooms divided into different parts with different functions or separated into two or more rooms by arches or mobile dividers should be counted as multiple rooms;
- Multi-purpose rooms with kitchen corners should be included in the count.

Room: a space that receives air and light directly from the outside and that is large enough to hold a bed while leaving enough space for one person to move around. Bedrooms and living rooms, for instance, qualify as rooms as long as they meet the above characteristics. Kitchens, kitchenettes, extra spaces and bathrooms, on the other hand, do not count as rooms even if they satisfy these criteria. Rooms without windows do not count unless they serve a domestic function, like a bedroom.

Rooms with independent access: rooms (that are physically separate) with direct outside access that does not depend on any other rooms in the main body of the dwelling. Rooms like these are used by the same people who live there and serve as a functional complement to the dwelling.

Associated structures: cellars, attics, garages, etc., i.e. rooms that are designed and used regularly to service the dwelling (but not necessarily located in the same building).

Accessory space: spaces that serve as access areas for rooms, bathrooms and sanitary facilities, storage closets and similar. These include entryways, internal stairways, hallways, bathrooms, dressing rooms, storage closets, etc.

Kitchen: a room (or part of a room) equipped with cooking equipment and appliances and a permanent dish-washing system, and used for these purposes whether or not eating, sleeping or other activities take place in the same space. Three categories serve to classify different types of kitchens based on size and purpose:

a) full kitchen: a "traditional" room-sized (see definition of "room") kitchen equipped and used primarily for cooking and eating;
b) kitchenette: a kitchen that is smaller than a room, almost always just big enough to contain the necessary appliances;
c) kitchen corner: part of a larger room set aside for eating meals and also as a kitchen nook, a portion of which includes kitchen appliances. The room is used in different ways, and the kitchen itself is not its primary purpose.
