The reported major failure causes are structural failure (SF), Carelessness (CLSS), poor workmanship (PW), poor supervision (PS), poor materials (PM), and quackery (Q).These causes of failure were subjected to Chi-Square statistical test at 5% significant level and 4 degree of freedom to know the most common cause of failure in Nigeria. The analysis showed quackery as the principal culprit in the reported building failures in Nigeria with prevalence of 8 over poor supervision being the minimum in occurrence. Structural failure occurred 5 times, while poor materials, carelessness and poor workmanship occurred 4, 2 and 2 respectively.
