The calculation of pool area is not a simple calculation of one or two households, but based on the unified calculation of the whole property, and a pool area is calculated as a whole. A simple and rude understanding is that the apartment with one staircase and two households, and the shared area of the aisle is half that of two households and one person, which is still not accurate. According to the Rules for the Calculation of Commercial Housing Sales Area and Allocation of Public Building Area of the Ministry of Construction, the public building area that can be allocated includes: lobby, public hall, corridor, aisle, public toilet, elevator hall, stairwell, elevator shaft, elevator machine room, garbage chute, pipe shaft, fire control room, water pump room, water tank room, freezer room and fire protection. Half of the horizontal projection area of partition wall and external wall (including gables) between suite and public building space.
legal ground
Article 272 of the Civil Code of People's Republic of China (PRC): The owner has the right to possess, use, profit from and dispose of the exclusive part of his building. The owner's exercise of rights shall not endanger the safety of the building or damage the legitimate rights and interests of other owners.
Article 273 of the Civil Code of People's Republic of China (PRC): The owner shall enjoy the rights and undertake the obligations for the part other than the exclusive part of the building; You may not fail to perform your obligations on the grounds of giving up your rights. When the owner transfers the residential and business premises in the building, part of its * * * ownership and * * * management rights are transferred together.
Allocation coefficient = sum of public area to be allocated/sum of construction area in each suite = (sum of total construction area-sum of construction area in each suite)/sum of construction area in each household. Public sharing area of each suite = sharing coefficient × building area of each suite.
