"Physical regeneration”, "social regeneration”, "environmental regeneration”, "urban managemnet regeneration”, and "economic regeneration” were extracted from the qualitative analysis as the legal components of resilience in the process of urban decay regeneration. Meanwhile, considering social complications and the influence of the community on the neighborhood indicated that establishing ties between the neighborhood in question and other neighborhoods of Tehran and their residents is the prerequisite to the realization of regeneration objectives in the historical area. Improving the social condition in the neighborhoods with greater sense of attachment can be materialized through the improvement of social indicators, increase in the quality of life and sense of satisfaction, preventing immigration, and eventually, providing better development platforms. Meanwhile, given the importance of urban management in urban development, a holistic, integrated, and inclusive approach which draws upon social and financial condition of the residents and preventing trivial actions in housing sector can help to achieve the regeneration objectives in the improvement of resilience.

The findings indicate that planning to improve social indicators must be the highest priority of lawmakers in order that the improvement in development platform can facilitate the realization of regeneration objectives.
