India’s rapid industrialization and urbanization have intensified demand for sustainable and affordable housing, especially for industrial workers, a critical yet marginalized urban workforce segment. This study evaluates twelve validated sustainability parameters for worker housing in Noida, a major industrial hub in the National Capital Region. Using an explanatory sequential mixed-methods design, it combines a three-round Delphi survey of 35 experts with structured interviews of 109 workers across three industrial phases. Indicators derive from UN-Habitat’s four-dimensional framework and are operationalized as measurable survey constructs. A composite sustainability score of 33.2 out of 100 shows conditions are inadequate across social (34.2), economic (31.6), cultural (28.7), and environmental (38.4) dimensions. Affordability analysis shows rent-to-income ratios of 31.8-42.3 percent, exceeding accepted thresholds for all low-income groups. Employer housing support is nearly absent (94.5 percent), while 87.2 percent depend on single incomes, amplifying insecurity. The study proposes a planning framework linking quantified gaps to four categories of actionable policy recommendations, offering a transferable, replicable assessment tool for industrial cities across the Global South. It strengthens evidence-based policymaking by aligning worker needs with spatial planning priorities, governance mechanisms, and inclusive housing strategies to support durable urban resilience and equity in dynamic metropolitan regions worldwide.
