This study aims to extract parameters defining neighborhoods from the residents’ points of view and compare them to those understood by experts. Experts’ proposed parameters and factors were extracted from the literature review, and residents’ parameters were obtained from conducting in-depth interviews analyzed by the Grounded theory method. Comparing experts’ and residents’ parameters shows weak, medium, and strong conformity between their parameters. Also, their factors, which are defining parameters, are different. Thus, parameters defining neighborhoods are not generalizable and cultural characteristics and local values of residents need to be considered in planning and policymaking for neighborhoods
