Why do industrial parks charge property fees?

Property has the cost of maintenance. In general industrial parks, roads, lighting, water supply and drainage are used. And some power supply and distribution systems are also separated from the big tables in the park, resulting in energy consumption and maintenance costs. Not to mention the greening and cleaning of the park, there must be costs. In some office areas of industrial parks, property fees will be lower. Housing charges can generally be negotiated to see how to communicate with property service units.
