23. Year of construction (item 3).
The year when the building was put into commission is considered the year of construction. This is the year when the building's work was completed (when all the inside equipment was fixed and finishing works completed).
For buildings partially put into commission, the year of construction will be considered the year when the first dwelling was finished or if it was a single dwelling building, when the first room was ready for habitation.
For the buildings where extension attachments have been undertaken or new floors were added after the construction was finished, the year of construction may be the year when the building was originally constructed. If these additional spaces are larger than the initial building capacity (expressed by the size of the newly created surface), the year of construction will be considered the year of last additional construction (or the year an additional extra floor was constructed).
When the year of construction is unknown, this will be assessed by taking into consideration the following: similarity with other buildings from the same census sector or even other census sectors where the year of construction is known, or the existence of construction materials or of a certain particular construction style that is characteristic to a certain years or period, etc.
