For a condominium-converted apartment building, the owners' association should separate two questions before the manager places certain orders. Is the proposed contractor connected to the manager by a family or economic relationship? And do the works go beyond ongoing maintenance or amount to a major improvement, for which at least three quotations must be obtained? Section 20(4) WEG links these transparency duties to property management.
The rule creates a traceable basis for the owners' decision. It does not decide whether works are technically necessary, and this provision does not automatically require the cheapest quotation to be selected. This article deals exclusively with a WEG owners' association after condominium conversion. An undivided apartment building owned by one person must be assessed separately.
