When calculating the housing maintenance fund, it is generally calculated by multiplying the cost price per square meter of the construction area by the proportion multiplied by the area, mainly according to the local economic level and the standards of the housing maintenance fund. Some cities charge 2% or 3% of the total housing transactions. When charging, there are some differences between different shell types, such as:

1. The first special maintenance fund for multi-storey residential buildings with elevators is 90 yuan/m2.

2. The first special maintenance fund for multi-storey houses and villas is 50 yuan/m2.

The so-called housing maintenance fund refers to the fund specially used for housing public facilities, which is used for projects such as the renewal and transformation of property parts and public facilities and equipment. Because it is earmarked, it cannot be used for other purposes. After payment, if the house is transferred, the balance in the account will also be transferred to the new owner's name, and only when the balance in the account is less than 30%, it is necessary to pay again.
