While building maintenance is now recognized as a measure for sustainable development, the impacts are increasing and pose risks to sustainable development. However, attempts to increase consideration of sustainable practice in residential buildings have not yielded positive results. Behavioral practice has potential for change, so in this study the behaviors of maintenance service providers are explored to investigate the understanding of the supply side in the sustainable housing supply chain and marketplace. The results indicate that the major factors that impact sustainable maintenance behavior is a poor understanding of maintenance organizations towards sustainable residences. A maintenance behavioral model is presented to prompt interest in sustainable-maintenance management.
