Social sustainability is considered the least defined and addressed pillar among the three pillars of sustainability. Social sustainability goals and targets within sustainable development goals are currently considered vital factors for human beings, and it is a manner in which a society is formed based on people's wants and needs (Woodcraft et al., 2011). 
The concept of social sustainability has come into view by creating healthy and liveable societies with official and unofficial processes, systems, structures, and relations to support available capacity and the next generations (McKenzie, 2004). It should be noted that in order to achieve social sustainability, our space needs to have a series of features and focuses on addressing various sustainability topics such as liveability, social cohesion, social responsibility, human rights, health equity, education equity, workforce rights, and many other relevant social issues (Koning, 2002). 
In general, liveability is the sum of the socio-physical and socio-cultural factors that can improve and upgrade the living standards of any space. Liveability is a holistic paradigm of human development and community well-being based on the augmentation of twin physical-environmental and cultural dimensions of cities and their associated regions (Balsas, 2004; Onnom et al., 2018; Yassin, 2019).
One of the sub-items of social sustainability is social cohesion, which, according to social ecology theory, social conditions are not only created by physical factors, but personal and social factors are very effective. The indicator of social cohesion focused more on the social interaction and integration that can be achieved within a building and its surroundings. This aspect discusses social interaction concerning increasing sustainable practices by creating self-connection with the environment and its people (Omann & Spangenberg, 2002; Hulse & Stone, 2007; Chan & Lee, 2008). Social cohesion can emphasize the need for a shared sense of morality and common purpose, aspects of social control and social order, the threat to social solidarity of income and wealth inequalities between people, groups, and places; the level of social interaction within communities or families; and a sense of belonging to place (Forrest & Kearns, 2001). So, we cannot talk about social cohesion and ignore the environment and individual characteristics.
In Iran's economic and social system, due to the issue of poverty, access to the parameters of a sustainable society depends on focusing on a certain group of people in the society that has low income and few facilities and are more vulnerable. These people should be considered more regarding their social and economic base. The living conditions of these people require special attention and a suitable environment. Commercial streets, especially Bazaars, are significant urban spaces in Iran, where these people can be seen in abundance. From ancient times, the Bazaar, as the spine of an Iranian city, has been a place for commuting, business, interchange of visits, leisure, and preparing daily needs. Even though bazaars were first built with economic aims, their skeletal and architectural features were such that they turned into a world of activities, social interactions, and urban events. However, it should be noted that in the contemporary Bazaars, the attention to all these matters was reduced (Falamaki, 2006).
One of the other important components of livability in Bazaars is street vendors. The street is not just considered a road to go somewhere for street vendors but an appropriate place of livelihood filled with hopes and struggles (Boonjubun, 2017). As an essential area of interest for environmental policy, the informal economy is integrated with social sustainability (Jones et al., 2017).
