All compartments of the dwelling, including bathrooms and kitchens, separated by walls, and those found on the outside part of the building should be considered rooms, as long as they are an integral part of the household.
Do not consider in the total number of rooms any corridors, porches, open verandas and other compartments used for non-residential purposes, such as garages, warehouses, etc.
When the number of rooms is fewer than 10, complete with a zero to the left.
