What is apportioned common floor space? What is the apportionment principle

The common floor area refers to the floor area of the common part of the whole building jointly owned by the property owners of the whole building. The apportioned common floor area refers to the common floor area of each set (unit) of commercial housing that shall be apportioned according to law.

The common floor area includes:

Elevator shafts, stairs, garbage chutes, substation rooms, equipment rooms, public foyers and walking fatigue, underground equipment, guard rooms on duty, etc.

Half of the horizontal projection area of the partition wall between the set (unit) and the common building space and the exterior wall (including the gable). Common building area The total building area The sum of the building area of each set of the whole building The construction area of the independent use space with separate use functions (such as underground garages, warehouses, civil air defense projects, etc.).

Common floor area apportionment factor.

The common floor area of the whole building is divided by the sum of the floor area of each set of the whole building to obtain the common floor area apportionment coefficient of the building.

The apportionment of the common area of the suite * the apportionment coefficient of the common building area, the apportionment principle of the common floor area of the house, the apportionment of the common floor area of the building is based on the unit. The common floor area apportionment is limited to the common floor area within the building. Public buildings that are not connected to the building (such as substation rooms, pump rooms, guard rooms, etc.) shall not be allocated to the house.

The common floor area of the house shall be apportioned according to the proportion of the floor area in each household unit multiplied by the relevant area in the house. After the common floor area is apportioned, the specific part of the area apportioned by each household is not distinguished. Once the common building area is apportioned, no one shall encroach upon or change the use function of the original design.

Commercial, residential and office complex buildings, the internal parts of the house use function, room type separation is quite different, should be according to its use or room type separation, according to the relevant area proportion of the whole building common construction area (the smallest unit of this apportionment is the floor), and then apportionment of the respective common construction area.

Commercial housing is divided into "sets" or "units"**. The sales area of commercial housing refers to the construction area of the suite or unit (hereinafter referred to as the construction area of the suite) purchased by the buyer and the common construction area that should be apportioned.

The building area of the set (unit) = the construction area of the set + the common building area apportioned.

Which common floor areas can be apportioned and what are the apportionment principles, which common building areas can be apportioned and what are the apportionment principles.

What is the apportionment principle of common floor area?

The common floor area is apportioned on a building-by-building basis. The apportioned common floor area is the common floor area in the building, and the common floor area not connected to the building shall not be apportioned to the building.

The common floor area serving the entire commercial building shall be apportioned by each set of commercial housing in the building; The common floor area for local services is apportioned by the beneficiary commercial houses. If the common floor area is apportioned multiple times, the apportionment coefficient shall be calculated separately. The common floor area to be apportioned for each set of commercial buildings is the sum of the common floor area to be apportioned at each time.

After the common construction area is apportioned, the specific part of the construction area of each set of commercial housing shall not be divided, but no one shall encroach on or change the use function of the original design.

Which common floor areas can be apportioned?

The following common areas of the entire building can be apportioned:

Lobby, public foyer, corridor, aisle, public toilet, electric (building) elevator vestibule, stairwell, elevator shaft, elevator machine room, garbage channel, pipe well, fire control room, pump room, water tank room, refrigeration room, fire passage, transformer (distribution) room, gas pressure regulating room, satellite TV receiver room, air conditioning room, hot water boiler room, elevator worker lounge, guard room on duty, property management room, etc.

Half of the horizontal projection area of the partition wall and external wall (including gable) between the set and the common building space.

For the calculation of the floor area, the floor height (height) should be above meters (including meters, the same below).

What common floor area cannot be apportioned?

Warehouses, motorized garages, non-motorized garages, driveways, heating boiler rooms, basements used as civil air defense projects, and independent use spaces with separate use functions.

Houses sold for self-operation and self-use.

Guardhouse, management (including property management) premises serving multiple houses.

According to the Ministry of Construction's "Rules for the Calculation of the Sales Area of Commercial Housing and the Apportionment of Common Construction Area", the apportionable common building area includes the lobby, the hallway, the corridor, the aisle, the public toilet, the electric (building) vestibule, the stairwell, the elevator shaft, the elevator machine room, the garbage channel, the pipe well, the fire control room, the pump room, the water tank room, the refrigeration room, the fire escape, the transformer (distribution) room, the gas pressure regulating room, the satellite TV receiver room, the air conditioning room, the hot water boiler room, the elevator worker's lounge, Duty guardhouse, property management room, etc., as well as special equipment room for basic function service of the building; Half of the horizontal projection area of the partition wall and external wall (including gable) between the set and the common building space.

Article 11 of the Rules for the Calculation of the Sales Area of Commercial Housing and the Apportionment of the Common Building Area.

The following common areas should be apportioned: elevator shafts, stairwells, garbage chutes, substation rooms, equipment rooms, public foyers and aisles, basements, guard rooms on duty, and other public and administrative buildings that functionally serve the entire building.
