The study assessed the perceptions of stakeholders on factors causing sports facilities defects in selected universities established between 1957 and 1962 in South-West Nigeria by examining the strength of the identified factors responsible for sports facilities’ defects in the selected universities. Data were collected using a structured questionnaire which was administered on sports men and women and maintenance personnel. The study incorporated all the fifteen sports featured at the Nigeria University Games Association (NUGA) competitions. Three federal universities were purposively selected because these have facilities for all the fifteen sports and have hosted national and international sporting events. Data obtained were analysed using frequency distribution, percentages, mean response analysis and factor analysis. Using the mean response analysis, the result showed that the most severe factors responsible for sports facilities’ defects were design deficiencies (3.67), intensity of use (3.53), level of exposure to climatic condition (3.41), inadequate maintenance funding (3.19), vandalism (3.18), moisture (3.17) and inadequate cash flow analysis (3.16). The study recommends that users of the facilities should be carried along at the designs stage to minimize design errors and also adequate fund should be provided to maintenance unit to guarantee adequate maintenance of sports facilities for optimal performance.
