A large portion of the credits and financial resources of countries is spent on the preparation and construction of building projects because their implementation would create housing, job opportunities, financial turnover, and economic prosperity. At present, many construction projects are under construction in developing countries, and most of these projects are facing rising costs. The local scope of this research is construction projects in Yazd city. This research is operational in terms of purpose and was carried out in a descriptive and survey manner with an analytical-mathematical method. Data collection was done by documentary and survey methods. The Statistical Society consisted of 150 managers and officials, contractors, and actors involved in construction projects. Data analysis by hierarchical analysis technique showed that the criterion of management factors with a weight of 0.582 has the highest priority in increasing building costs. The criterion of environmental factors with a weight of 0.309 is at the second priority. The criterion of legal and administrative factors with a weight of 0.109 is in the third priority. Therefore, a key element in increasing the cost of construction projects in the under-studied city is the management factor that can be reduced by establishing new management systems and improving the quality of construction projects.
