In addition to the cost of buying land, the developer's cost is divided into two parts. One part is hard costs, including construction costs of cement, steel, water pipes, etc., and the other part is soft costs, which include attorney fees, management costs, assessments, and environmental assessments. The cost is relatively flexible, and some projects take a short time from project establishment to start of construction. The cost may be lower. For some projects, such as Tridel's CIRCA in MARKHAM, it took 8 years from the beginning to the start of the project. So the soft cost is high. Generally speaking, the soft cost is the hard cost 30%-60%. The following table is the classification and proportion of hard costs.
