The present paper is derived from a study conducted in 2020 under the title “Social and cultural impacts of the construction of a wet market in Karaj region 7”. The most important purpose of this study is to make sure the designed project conforms to the surrounding social and cultural context and also to improve their interaction and effective relationship. Considering that the design and construction of the wet market have both positive and negative effects and impacts – on the one hand, its establishment and operation can cause problems and difficulties for the neighbors and local residents of the project, and on the other hand, it can contribute to economic benefits, social justice, and reducing intra-city traffic – it reveals the necessity of research on social and cultural effects and impacts. The research method of this study is a combination of quantitative (survey) and qualitative (field observation and in-depth interview) research. Qualitative methods have been used for exploratory studies and quantitative methods have been used to ascertain the findings of those studies. Findings of the research indicate that the most important effects based on size and scope, extent, frequency, and composition are: 1- Demographic changes 2- Assessing people’s perceptions about public health and safety (traffic and pollution) 3 - Disruption of daily life 4- Assessing the change in commercial centralization of the community 5- Impact on business and employment 6- Assessing the formation of attitudes towards the project 7- Assessing the activities of the stakeholder group 8- Trading real estate and land. Finally, a smart monitoring system is developed to reduce the negative impacts of the design and construction of the wet market and strategies to strengthen the positive impacts.
