How is the rental area calculated?
When leasing a house or commercial space, the way the area is calculated is directly related to the rent and actual usage experience. In recent years, there have been frequent disputes over the leased area. In particular, issues such as whether the "shared area" should be included in the rent and how to measure the actual used area have become hot topics. This article will combine the hot discussions on the Internet in the past 10 days to provide you with a detailed analysis of the calculation method of rental area and provide structured data reference.
1. Common calculation methods for rental area

Currently, there are three main ways to calculate rental area:
| Calculation method | definition | Applicable scenarios |
|---|---|---|
| Building area | Including the apartment area and shared area (such as corridors, elevator rooms, etc.) | Commonly seen in commercial housing rentals |
| Inner area | Actual usable indoor area, excluding public stalls | Apartment and office space rental |
| Used area | Net area after deducting wall thickness | Commonly used in Japan, European and American countries |
2. Controversies and Latest Developments over the Sharing Area
Recently, the topic #sharingareashouldbecancelled# has become a hot search topic, and netizens in many places have called for "pricing based on the area within the suite." The following is a reference for public share ratios in some cities:
| city | Average residential share rate | Commercial property sharing rate |
|---|---|---|
| Beijing | 25%-30% | 35%-50% |
| Shanghai | 22%-28% | 30%-45% |
| Guangzhou | 20%-25% | 25%-40% |
3. Key points for area calculation of different property types
1.Residential rental: Need to clarify whether the balcony area is included (usually converted at 50%)
2.Office rental: Pay attention to the concept of "occupancy rate" (usable area/construction area)
3.Shop leasing: There may be "virtual area" (such as the swing-out area included in the rent)
| Property type | key indicators | Industry practice |
|---|---|---|
| LOFT Apartment | Floor height ≥4.5m can be counted as double area | Planning permission required |
| Shared office | Number of workstations×per capita area standard | Usually ≥5㎡/person |
4. New trends in the leasing market in 2023
According to the latest statistics:
| Trend | Data performance | Regional differences |
|---|---|---|
| Flexible leasing | Short-term rental demand increased by 37% | First-tier cities are more prominent |
| Area transparency | 82% of tenants require survey drawings | New first-tier cities take the lead |
5. Practical suggestions
1. Be sure to verify the registered area on the property certificate before signing the contract.
2. Ask the landlord to provide a floor plan with dimensions
3. For commercial leasing, you can hire a professional surveying agency to review
4. Pay attention to new local regulations (for example, Chongqing has piloted in-house pricing)
Recently, the Ministry of Housing and Urban-Rural Development responded to the "shared area" controversy and stated that it is studying and formulating relevant standards. It is recommended that tenants use "rent per square meter of actual usable area" as the comparison standard when calculating rental costs to avoid misunderstandings caused by different calculation methods.
From the above analysis, it can be seen that the calculation of rental area requires comprehensive judgment based on property type, regional practices and the latest policies. Only by clarifying the calculation standards can the legitimate rights and interests of both parties to the lease be protected.
