58. What year was this dwelling or flat built?

Part 3: Information about housing
The DTV collects information about the housing situation of the household. Do not collect housing information for specific demographics.

Question 58: From what year was this house/apartment used?
The DTV records the year in which the house was completed and put into use for the first time. In case a household's house consists of many parts, each part is completed and started to live in different years, the DTV only records the year in which the main part (with the largest area) of that house was completed and first put into use for living.

In case the owner household does not remember which year the house was put into use, the DTV chooses the code "Undetermined".

With remodeled houses: If a major repair causes changes to the structure of the house, record the year of the repair; If minor repairs, enter the year of the most recent major repair or the year of first use (in case there was never a major repair).

For example: A house was built in 1990 and has a tiled roof. In 2000, the tiled roof was removed, and renovated to facilitate pouring a concrete ceiling and building an additional floor. In 2005, the house was renovated and another floor was built. In this case, the DTV records the year of use of the house as 2000 because this is the year in which the house underwent its biggest structural change.
