How to calculate the area of community pool? 10-day network hotspot analysis and structured guide
Recently, "shared area" has once again become a hot topic across the Internet. Especially in the context of frequent disputes over the delivery of new homes, issues such as how to calculate the shared area and whether there are any tricks have attracted widespread attention. This article will combine the popular discussions in the past 10 days and use structured data to clearly analyze the calculation rules of shared area for you.
1. Definition and composition of shared area
The shared area refers to the public building area shared by the owners of the entire building, which usually includes the following parts:
| Public stall area | Specific content | Example of apportionment ratio |
|---|---|---|
| Elevator shaft/stairwell | core traffic area | 15%-25% |
| Equipment room | Water, electricity and heating equipment room | 5%-10% |
| public foyer | Unit lobby and aisle | 8%-12% |
| Exterior wall projection | building facade | 10%-15% |
2. Hot controversy data in 2024 (last 10 days)
| focus of controversy | Hot search platform | Number of discussions (10,000) |
|---|---|---|
| Is it reasonable for the public share to exceed 30%? | Weibo/Douyin | 280+ |
| Fine decoration is charged according to the building area | little red book | 150+ |
| Installing elevators in old residential areas | Today's headlines | 90+ |
3. Calculation formula of public pool area
According to the "Regulations on Calculation of Commercial Housing Sales Area", two core data need to be clarified in the calculation of public housing:
| Sharing coefficient | = Total common area ÷ Total area in the suite |
| personal pool | = Apartment area × sharing coefficient |
For example, if the total area of a certain building is 500㎡ and the total area is 2,000㎡, the pooling coefficient is 0.25. If the area of your apartment is 80㎡, you need to allocate 20㎡ to the shared area.
4. Guide to avoid pitfalls (from recent rights protection cases)
1.Verify surveying and mapping reports: The developer is required to present the surveying and mapping results table filed with the Housing Authority, and focus on checking the "Instructions on Shared Building Area Apportionment" column.
2.Be wary of unconventional allocations: A recently exposed property includes an independent garage as a pool. In such cases, rights can be safeguarded through administrative litigation.
3.Differences between old and new specifications: Starting from 2023, new residential buildings will comply with the "General Code for Civil Buildings" (GB 55031-2022), and the exterior wall surface layer included in the construction area may increase by 1%-3%.
5. Comparison of the proportion of public stalls in typical cities across the country
| city | Average share of high-rise residential buildings | Policy features |
|---|---|---|
| Beijing | 22%-26% | Requesting disclosure of apportionment details |
| Shanghai | 20%-24% | The pilot is priced based on the area within the unit. |
| Chongqing | 15%-18% | In-package pricing has been implemented since 2002 |
| Guangzhou | 18%-22% | Random inspection by third-party surveying and mapping agency |
Conclusion:Recently, the Ministry of Housing and Urban-Rural Development responded to the proposal to "cancel public sharing" and stated that "careful study is needed." Under the current system, it is recommended that when purchasing a house, the developer be required to make a written commitment that the error in public sharing will not exceed 3% and retain all area certification documents. If it is found that the actual share exceeds the contract stipulation by more than 5%, the difference can be requested in accordance with the "Commercial Housing Sales Management Measures".
