Introduction: Deterioration is detectable in various forms in urban system even physical and unphysical, which needs appropriate way to cope with. In order to plan improvement of these capacities especially capacity of social participation, as an effective element which not only simplifies the physical interference but also gives us important feedbacks of rebuilding the social contacts in neighborhoods, assessment of them seems to be necessary.

  Method: To assessment and evaluation this capacities in this paper, it has been reviewed the topics of Capacity building, Social capital and Regeneration. Then the indexes and sub-indexes have been chosen with the social-based approach as the paradigm of act and then their relationships have been analyzed by using data which come from field research. The section of analysis comes up in two levels: 1- description of data by using frequency distribution table and central indexes and scattering indexes 2- finding the effect of independent varieties on dependent varieties by path analysis method and regression method.

  Findings: The results have indicated that on average 87.2% of participants partake in the activities of the community.

  Conclusion: There is a direct correlation between the independent variables -length of residency in the neighborhood, communality, and the belief in the communal values- and the dependent variable community involvement.
