• Unforeseen reuse is not shown if there is no unforeseen reuse factor in the declaration or it is set to 0.

• Unforeseen reuse is not shown for declarations with an expected year of construction (bouwjaar) in 2010 or later.

• Unforeseen reuse is shown only for declarations with an unforeseen reuse factor and an expected year of construction before 2010.

• Unforeseen reuse is not visible if the expected year of construction (bouwjaar) is not defined in the url query parameters.
