Abstract: The emergence of a plethora of innovative construction methods, materials and technologies in the construction industry has been projected to enhance the effective delivery of sustainable affordable housing. However, a lack of empirical evidence buttressing an extensive analysis of the effect of internal and external influencers on adopting these innovations within the affordable housing context in developing countries persists. This study examines the nexus between company and project characteristics as internal influencers, and challenges as external influencers, on the extent of use of sustainability‐oriented innovations (SOIs), on affordable housing projects. Variables emanating from an extensive literature review were presented in a causal model detailing sustainable, innovative, and affordable housing (SIAH). The model and the inherent causality between the constructs were validated through a survey administered on a population of registered South African home developers. The results of structural equation modelling posit a minimal positive impact of internal influencers and moderate negative effects of external challenges on the extent of use of SOIs by home developers. Also, results highlighted the negative mediating impact of challenges on the relationship between internal influences and the extent of use of SOI in affordable housing projects. The study concludes that the external challenges are the key drivers of adopting innovation in SIAH, and by addressing these challenges, the extent of use will significantly improve. The validated causal model can be used as a framework to enhance SOIs adoption in SIAH.
