In this study, we examine the adoption of sustainable management practice (SMP) for green features in an office building using Lagos office property as a case study. The opinion of the professional property managers was sampled, and their responses were analyzed by weighted mean score (WMS), one simple test statistic (t-stats), severity index (S.I.), and factor analysis model. The study discovered that while energy-efficient related green features were the most incorporated, property managers often manage the efficient use of spaces among other green features in the office property. The property managers are yet to fully adopt the SMP, but sustainable resource management and repair and replacement maintenance management were highly considered among the SMP. The challenges of SMP were categorized into three broad barriers: GB project cost/finance, economic/market expectation, and professionalism/institutional barriers. We concluded that the country's property managers are yet to adopt SMP fully. We recommended the integrated GB practice advocacy, encouragement of strong institutional backing for developing the country's GB rating tools, and professionalism for SMP to thrive in the country.
