Abstract: Sustainable construction remains under-adopted due to first-cost premiums, uneven enforcement, capability gaps, and fragmented information. This article contributes a context-fit roadmap by identifying and prioritizing strategies across regulatory, market, informational, and capability levers. A mixed-methods, cross-sectional design combined a structured Likert-scale questionnaire with semi-structured interviews of purposively sampled industry actors; descriptive statistics ranked strategies and narratives clarified complementarities. All strategies were rated effective (aggregate mean ≈ 4.21; SD ≈ 0.96). Highest support emerged for client/end-user education via case studies and county-level demonstration centres, followed by curriculum integration, building-code revision, stakeholder empowerment, approval-stage sustainability checklists, and targeted financial incentives. Findings corroborate diffusion and international evidence, adding nuance on the outsized role of visible exemplars and client-facing education. Recommended actions include updating codes, embedding approval checklists, deploying time-bound incentives, expanding labeling and cost–benefit data, integrating sustainability in curricula/CPD, establishing demonstration centres, and instituting adaptive monitoring. Keywords: Sustainable Construction, Adoption Strategies, Policy Instruments, Financial Incentives, Diffusion of Innovations, Capacity Building.
