The reason why the parking space maintenance fund is calculated according to the construction area is that the frequency of use and maintenance costs of different parking spaces may be different. Larger parking spaces are usually more vulnerable to vehicle scratches, oil pollution and other damage, and maintenance costs will increase accordingly. Therefore, calculating the parking space maintenance fund according to the construction area can share the maintenance cost more fairly, so that each owner can pay the cost according to the proportion of his own construction area, and can also better reflect the size of his own right to use and maintenance responsibility.
