This study employed a mixed qualitative-quantitative methodology to examine the influential factors in providing affordable housing within the framework of Iran’s socio-cultural patterns. In the qualitative phase, preliminary factors were identified through meta-synthesis of 33 credible articles. Subsequently, in the quantitative phase, these factors were evaluated and validated using confirmatory factor analysis with the participation of 273 housing specialists, managers, and experts. The findings reveal that multiple factors play significant roles, including: standardization and modularization of design and construction, utilization of natural ventilation and climate-adaptive strategies, implementation of modern construction technologies, the use of sustainable and recyclable materials, increased productivity in production and execution processes, design flexibility to meet user needs, energy consumption optimization and environmental impact reduction, construction waste management, reduced reliance on human labor, provision of psychological comfort for residents, utilization of natural lighting, enhancement of neighborhood relationships and social interactions, preservation of architectural identity, reduction of construction and maintenance costs, and future-oriented design approaches. The study shows that the successful provision of affordable housing in Iran requires simultaneous attention to technical, environmental, socio-cultural, and economic dimensions. Accordingly, it is recommended that policies such as developing construction standards, promoting the use of sustainable materials, formulating climate-appropriate design guidelines, and strengthening social participation in housing projects be implemented
