We have 8 years to 2030, when the promises and targets of sustainable development and smart growth are expected to be achieved at the global level, the agenda items about sustainability remain urgent. Sustainable development and smart growth are more important than ever. The managers of the Sustainable and Smart concepts are local governments that own urban units and can make more critical decisions due to scale permits, rather than the changing policies of states. Considering the point reached, it can be observed that the concepts of the sustainable neighborhood, community and city are based on different foundations in the light of assessment tools and models, although the urban terminology that develops with the concept of sustainability is often used to support each other. It can even be said that its sustainable indicators are close to smart city criteria rather than sustainability criteria. In this study, sustainable neighborhood, community and city criteria, the mentioned urban units were determined, defined, and interpreted through 18 assessment tools, guidelines, standards, and models in total.
