Defects and damage to heritage buildings are a major problem that organizations need to understand and address. Lack of information on heritage building defects results in authorities making decisions or actions that do not meet the essential criteria. This research is intended to identify the types of defects that existed in heritage buildings and to identify the degree of errors that are being investigated in them. Nine (9) heritage buildings from eight (8) states in Malaysia have been reviewed and systematic visual evaluation approaches have been applied to the main building consisting of seven (7) major building components, namely roofs, walls, columns and beams, windows, doors, floors, staircases and aprons, including building services such as air conditioning. The previous researchers have generally identified a total of thirty-three (33) defects in heritage buildings. The results of the evaluation indicate that twenty-four (24) highly significant defects occur frequently in five (5) primary defect groups, namely humidity (29.33 %), peeling paint (21.0%), fungus attacked / affected growth (19.0%), poor installation of air conditioning units (8.0 percent), cracks (7.67%) and the remainder are below 5.0%. A sum of seven investigation buildings starts with external wall component (EW: 33.67 %) deficiency followed by column and beam (CB: 21.67 %), rooftop (R: 15.0 %) and outer floor, stairs and apron (EFSA: 14.0 %). The identification of three (3) major defects is a clear evidence for the authorityto assume, and to demonstratea specific framework and effective strong-armaction in refurbishdetecteddefects.This investigation approach is one of its sort in Malaysia and is relied upon to positively affect the field of protection towards the legacy structures in Malaysia.
