How to calculate common ground? Understand the calculation method of common area in one article
In recent years, with the hot real estate market, the calculation of common area has become the focus of home buyers. The common area refers to the common part of the building area jointly owned by the owner of the entire building, including elevator shafts, stairwells, garbage passages, substation rooms, etc. So, how to calculate the common area? This article will analyze it in detail for you.
1. Calculation formula for common area
The calculation formula for common area is as follows:
| project | Calculation formula |
|---|---|
| Common coefficient | Common coefficient = Total common area / Total in-set area |
| Common area | Common area = Common coefficient × In-set area |
| Building area | Building area = Interior area + Common area |
It should be noted that the common coefficients in different regions may vary, and the specificity is subject to local policies.
2. What parts does the common area contain?
Common areas usually include the following parts:
| Common part | illustrate |
|---|---|
| Elevator well | Vertical passage for elevator operation |
| Staircase | Public stairs connecting each floor |

In addition, different regions also have provisions on the upper limit of common area. For example, some cities stipulate that the common coefficient of ordinary residential buildings shall not exceed 25%, while the common coefficient of high-end residential buildings may be higher.
