Increasing urbanization and population growth have brought forth numerous challenges in urban environments. This unyielding expansion, encompassing aspects of physical, social, economic, and environmental dimensions, has impeded the realization of sustainability in urban contexts. Compounded by issues like environmental pollution and diminished tranquility among inhabitants, these developments have adversely affected the quality of urban life. Consequently, the concepts of livability and sustainable development have gained paramount importance in contemporary urban settings. This study aims to analyze the livability of the Cyrus neighborhood, with a focus on sustainable development in District 12 of the Tehran Municipality. Methodologically, this research adopts a descriptive-analytical approach and falls under the category of applied research, aiming to address specific objectives. The statistical population encompasses experts from the Tehran Municipality of District 12 and the Cyrus Neighborhood Development Office, utilizing probability and stratified sampling techniques. The research results offer an in-depth analysis and comprehension of the Cyrus neighborhood’s livability, centered on sustainable development. It proposes a model grounded in the theoretical framework and data analyzed through a one-sample T-test and structural equation modeling. The findings reveal that, when viewed through the lens of sustainable development, the livability status in the Cyrus neighborhood is deemed average and unsatisfactory. Structural equation modeling results demonstrate that physical-environmental factors, with a beta coefficient of 34.24, exert the most influence on the neighborhood’s livability. In contrast, managerial factors, with a beta coefficient of 4.2, exhibit the least impact.
