Purpose: The paper aims at indicating the main reasons of construction defects found during the acceptance of multifamily residential buildings and determine the diminished value of a defective component by means of the use value analysis.
Method: The author showed the application of Aurnhammer's method to determine the diminished value of a component.
Findings: The defects found during the acceptance carried out by inspectors and by apartment buyers are very similar - mainly the absence of right angles between walls, scratched window panes and window sills and uneven and scratched walls. Based on Aurnhammer's method, it was estimated that the value of window joinery diminished by 7.6% and the value of screed diminished by 15.6%. The evaluation of diminished value can be done using a block diagram. The analysis indicated that the window value diminished by 8% and the internal plasters value diminished by 13.75%. The limitation of the research is the assessment of the real state of the element made visually on a subjective scale and possible errors in the cost calculation that inflate or underestimate the value of the evaluated element.
Research implications: The presented methods may be used during the acceptance of flats - they may help the supervision inspector in deciding on the acceptance of the flat, as well as by the contractor's representative who during the acceptance of the flat can quickly estimate the diminished value of an element which may have the defect detected during the acceptance of the flat.
