How to calculate the indoor area? 50 problems to be paid attention to in buying a house according to the interior construction area

Relevant explanations about the new method

1. Why does the Measures stipulate that the pre-sale of commercial housing should be priced according to the interior construction area?

Mainly for the convenience of buyers to measure the area of purchased houses, and to determine whether the actual area of purchased houses is consistent with the area agreed in the commercial housing sales contract and the error rate. Before the promulgation of the "Measures", the relevant laws of our country stipulated that the sale of commercial housing could be priced according to the construction area, interior construction area or apartment type (unit). Therefore, many developers adopt the method of pricing by building area or unit when pre-selling commercial housing. Because these two methods are used to test whether the actual housing area delivered by the developer is consistent with the area agreed in the commercial housing sales contract, buyers must measure the shared floor area without exception. However, due to the complicated calculation method, difficulty and high cost, it is difficult for a single buyer to complete it independently, which is not conducive to effectively protecting the legitimate rights and interests of buyers. In order to change this situation, the "Measures" clearly stipulate that the pre-sale of commercial housing should be priced according to the interior construction area. In this way, buyers can avoid the problem of sharing the public building area, and can also measure the interior building area of the purchased house more conveniently, and judge whether the developer has violated their legitimate rights and interests accordingly.

2. Will the pre-sale of commercial housing priced according to the interior construction area cause changes in the price of commercial housing?

Pre-sale of commercial housing according to the interior construction area will cause changes in the unit price of commercial housing, that is, the unit price of commercial housing will increase. But it will not necessarily lead to an increase in the total price of commercial housing. Because it is priced by the interior construction area, the developer will include the cost of the public shared construction area in the interior construction area, thus increasing the unit price of commercial housing sales. At the same time, however, the valuation area of commercial housing no longer includes the public shared construction area. Therefore, unless the developer intends to increase the total housing price, the total housing price actually borne by the purchaser will not increase, which should basically be equivalent to the previous total housing price. As for the increase of the unit price of commercial housing, except for affordable housing, the unit price of other commercial housing should be independently calculated and priced by the developer according to the cost and income.

3. What is the indoor building area?

According to Article 4 of the Interim Provisions of Beijing Municipality on Calculation of Commercial Housing Sales Area and Allocation of Public Building Area, the interior building area of commercial housing refers to the sum of the interior use area, interior wall area and balcony building area of complete commercial housing (unit). Namely: interior construction area = interior usable area+interior wall area+balcony construction area.

4. How to calculate the interior usable area of the suite?

The usable area in the suite is the usable area of the house in the suite, which is calculated by the horizontal projection area. According to the Code for Design of Residential Buildings issued by the Ministry of Construction, different calculation codes apply to the calculation of usable area in suites according to whether the house is residential or not. Among them, the calculation method of the usable area in the house suite is as follows: ① The usable area in the suite includes the sum of the usable areas in the bedroom, living room, hall, aisle, kitchen, toilet, bathroom, storage room and closet; ② Indoor stairs of duplex apartment are included in the usable area according to the total area of natural floors; (3) Chimneys, ventilation pipes and pipe wells that are not included in the structural area are included in the use area; (4) The interior wall decoration thickness is included in the usable area. The calculation of the usable area of other buildings or proprietary buildings other than residential buildings can refer to residential buildings or be carried out according to the provisions of special building design codes.

5. How to calculate the interior wall area?

Interior wall area refers to the maintenance or load-bearing wall around the use space in each commercial house. The interior walls of commercial housing are divided into * * * walls and non-* * walls. Among them, * * * wall refers to the partition wall between commercial housing suites, the partition wall between suites and public building space, and the external wall (including gables). Non-wall refers to the wall designed for the use of commercial housing owners or users. According to the Interim Provisions on the Calculation of Commercial Housing Sales Area and the Allocation of Public Building Area in Beijing, the calculation method of the interior wall area of commercial housing is: * * Half of the horizontal projection area of the wall is included in the interior wall area. The horizontal projection area of non-* * walls is all included in the interior wall area.

6. How to calculate the balcony construction area?

According to the construction area calculation rules, the balcony construction area is calculated according to the horizontal projection area between the balcony periphery and the external wall of the house. Among them, the construction area of the closed balcony is calculated according to the horizontal projection area of its periphery; The balcony (bottom balcony) construction area is calculated according to half of the horizontal projection area of the floor where it is located; The construction area of concave balcony is calculated by half of its net area (including the wall area of partition wall); The construction area of the cantilever part of the semi-cantilever and semi-concave balcony is calculated according to half of the horizontal projection area of its bottom plate, and the construction area of the concave part is calculated according to half of its net area.

7. Can commercial housing sales be priced according to the construction area?

Of course. The Measures for the Administration of Commercial Housing Sales of the Ministry of Construction clearly stipulates that there are three pricing methods for commercial housing sales, namely, pricing by construction area, pricing by interior construction area and pricing by suite (unit). Therefore, the sale of commercial housing can be priced according to the construction area. Except for the sale of pre-sold commercial housing, the Administrative Measures of Beijing Municipality on Urban Real Estate Transfer clearly stipulates that the pre-sold commercial housing shall be priced according to the interior construction area from June 65438+February 1 2003.

8. What is the building area? How to calculate?

Construction area refers to the peripheral horizontal projection area of each floor above the external wall (column), including balcony, corridor, basement, outdoor stairs, etc. , and is a permanent building with a solid structure and a height of 2.20m (inclusive). The state has strict laws and regulations on the calculation of building area. For example, regarding whether the building glass curtain wall is used to calculate the building area, the Notice of the Ministry of Construction on Issues Related to Building Area Calculation and Housing Ownership Registration clearly stipulates that if there are both main walls and glass curtain walls on the same floor, the building area shall be calculated based on the main wall, and the wall thickness shall be calculated according to the thickness of the main wall; When the wall thickness of each floor is different, it will be calculated separately according to the floor. According to the Measures for the Management of Commercial Housing Sales issued by the Ministry of Construction, the construction area of commercial housing consists of interior construction area and shared interior construction area. That is, construction area = interior construction area+assessed * * * existing construction area.

9. Pre-sale commercial housing is priced according to the interior construction area.

Is it necessary to calculate the price according to the interior construction area when transferring ownership?

No. Because the pre-sale commercial housing priced according to the interior construction area refers to the commercial housing sold by developers to ordinary buyers for living, if the buyers transfer the house, the house will become a second-hand house instead of a pre-sale commercial housing, so there is no need to implement the policy of pricing according to the interior construction area that only pre-sale commercial housing must implement.

10. How to convert a house priced according to the interior construction area into a house priced according to the construction area?

It's simple. Just divide the total house price by the building area. For example, a set of pre-sale commercial housing, with an interior construction area of 80 square meters and a construction area of 100 square meter, has a total price of 400,000 yuan. Then according to the interior construction area, its sales unit price is 5000 yuan per square meter; According to the construction area, its sales unit price is 4000 yuan per square meter.

1 1. After the pre-sale of commercial housing is priced according to the interior construction area, how can buyers better safeguard their right to share the public construction area?

This question is more difficult. Because for various reasons, it is difficult for buyers to know exactly whether their shared public building area is reasonable, and it is also difficult to know whether the shared public building area delivered by developers is in breach of contract; At the same time, it is difficult for property buyers to effectively exercise the right of supervision and management over the construction and use of the shared building area, because these rights should be exercised by the owners' assembly or owners' committee of the community according to the current laws and regulations in China, and individual property buyers cannot exercise or decide. Therefore, after the pre-sale of commercial housing is priced according to the interior construction area, how to safeguard the right of buyers to share the public construction area is still a difficult problem for everyone.

12. What is the public building area and shared public building area?

Public building area refers to the building area shared by the property owner of the whole building and all public parts of the whole building. Apportioned public construction area refers to the public construction area allocated by each set (unit) of commercial housing according to law. The property right of public building area and shared public building area belongs to the purchaser of the whole building, and the purchaser enjoys the rights and assumes the responsibilities in accordance with the provisions of laws and regulations. Without the consent of all * * * people or the owners' meeting according to legal procedures, no one may occupy or change the original design function of the public building space of the whole building.

13. What is the allocation principle of public building area?

There are three principles for the allocation of public building area: ① The allocation of public building area is based on buildings. The shared public building area is the public building area in this building, and the public building area that is not connected with this building shall not be shared into this building. (2) The public building area serving the whole commercial house shall be shared by the commercial houses in the building; The public building area serving the local area shall be shared by the beneficiary commercial houses. If the public building area is shared many times, the sharing coefficient shall be calculated separately. The shared public construction area of each commercial house is the sum of the shared public construction area. (3) After sharing the construction area, the specific parts of the shared construction area of each commercial house will not be divided, but no one may occupy or change the original design function.

14. What public areas can be shared in the whole building?

The following public areas of the whole building can be shared: ① Lobby, public hall, corridor, aisle, public toilet, elevator lobby, stairwell, elevator shaft, elevator machine room, garbage chute, pipeline shaft, fire control room, water pump room, water tank room, freezer room, fire escape, power distribution room, gas surge chamber and satellite TV reception. ② Half of the horizontal projection area of partition wall and external wall (including gables) between suite and public building space.

15. Which building area should not be shared?

The apportioned parts that should not be included in the public building area are: ① warehouses, motor vehicle garages, non-motor vehicle garages, driveways, heating boiler rooms, basements used for civil air defense projects, and independent use spaces with independent use functions. (2) Houses sold by self-employed units. (3) Gatehouse and management (including property management) rooms serving multiple houses.

16. What pool should the developer clearly explain to the purchaser?

Before the pre-sale of commercial housing and after the completion of commercial housing, the developer shall clearly state the following apportionment to the purchaser: ① the name, purpose, location and area of the apportionment; (2) Name, purpose, location, area and allocation coefficient of the commercial house participating in the allocation of * * * construction area; (3) Not sharing * * * with parts. What needs to be explained here is that, except in statutory circumstances, the contents expressed by the developer to the purchaser twice should be consistent, otherwise the purchaser can investigate the developer's liability for breach of contract according to the agreement in the commercial housing sales contract.

17. How is the public building area that buyers should share calculated?

According to the "Calculation Rules for Allocation of Commercial Housing Sales Area and Public Building Area (Trial)" issued by the Ministry of Construction, each set (unit) shared public building area = allocation coefficient of public building area × interior building area, and shared public building area coefficient = sum of public building area of the whole building/interior building area of each set (unit) of the whole building, in which the public building area of the whole building is equal to the entire building area minus each set (unit) of the whole building.

18. What are the rules for the allocation of property management houses?

In order to prevent developers or property management enterprises from occupying and using residential houses in the name of property management houses, increase the public building area shared by buyers, and then increase the economic burden of buyers, China's property management laws and regulations stipulate that the maximum area of property management houses for new residential real estate projects shall not exceed 6‰ of the building area.

19. Does the purchaser have the right to know about the construction and use of the public building area?

Of course there is. Because the commercial housing area purchased by the purchaser consists of two parts: the interior construction area and the public shared construction area, and the interior construction area belongs to the purchaser's own use; The property right of the shared building area belongs to the owner of the whole building, and the purchaser enjoys rights and assumes obligations according to laws and regulations. Moreover, according to the "Property Management Regulations" and other laws and regulations, we can participate in and decide the construction and use of the public construction area of commercial housing through elections, participation in owners' meetings and owners' committees. In addition, the "Measures" clearly stipulate that developers should clearly explain the functions and specific conditions of public common parts to buyers, and give buyers the right to know about the construction and use of public common parts of commercial housing in legal form.

On contract and its liability for breach of contract

20. The pre-sale of commercial housing is priced according to the construction area, and there is an error between the pre-sale construction area and the interior construction area agreed in the commercial housing sales contract. How should the developer bear the liability for breach of contract?

According to the provisions of the Measures, if the pre-sale of commercial housing is priced according to the construction area, and there is an error between the pre-sale construction area and the measured area agreed in the pre-sale contract, the developer shall be investigated for breach of contract in accordance with the agreement of the commercial housing sales contract. If there is no agreement or unclear agreement in the contract, it shall be handled according to the following provisions: ① If the absolute value of the error ratio between the construction area and the measured area is within 3% (including 3%), the house price shall be settled according to the measured area; (two) the absolute value of the construction area error ratio exceeds 3%, in accordance with the provisions of the second paragraph of the first paragraph of article forty-seventh; ③ If the absolute value of the construction area error ratio is less than 3% (including 3%) and the absolute value of the interior construction area error ratio exceeds 3%, the purchaser has the right to return the house. If the buyer cancels the house purchase, the real estate development enterprise shall refund the house price paid by the buyer and its interest within 30 days from the date when the buyer requests to cancel the house purchase in writing; If the purchaser does not return the house, the house price shall be settled according to the measured area.

2 1. Pre-sold commercial housing is priced by unit. If the construction area of commercial housing agreed in the commercial housing sales contract is different from the actual construction area delivered by the developer, should the developer be held liable for breach of contract?

In accordance with the provisions of the Measures, if the pre-sale commercial housing is priced by unit, the contract for the sale of commercial housing shall specify the unit type, detailed area, error range and treatment method of the commercial housing in detail, and attach a plan. When the pre-sold commercial housing priced by units is actually delivered, the housing type is consistent with the design drawings, and if the relevant dimensions (construction area) are within the error range agreed in the commercial housing sales contract, the total price remains unchanged. If the sleeve type does not conform to the design drawings or the relevant dimensions are out of the agreed error range, it shall be handled in the way agreed in the contract; If there is no agreement in the contract, it shall be settled by the parties through consultation; If negotiation fails, it may apply for arbitration or bring a civil lawsuit according to law.

22. Does the predicted area and public allocation announced by the developer to the purchaser have legal effect?

Yes "Measures" stipulates that before the pre-sale of commercial housing, developers should publicize the predicted area of pre-sale commercial housing and the allocation of public building area to buyers. Part of the contents of the above publicity, such as the construction area of pre-sale commercial housing and the interior construction area, are written into the commercial housing sales contract, so they have legal effect. For the case that the pool part is not written into the commercial housing sales contract, the purchaser can make an agreement by signing a supplementary contract or an annex to the contract with the developer, making it a contract clause with the same legal effect as the commercial housing sales contract.

23. Is it necessary to modify the terms of the contract to sell the house according to the interior construction area?

The model text of the current commercial housing sales contract has already included the relevant contents of pricing according to the interior construction area. Therefore, if selling a house according to the interior area is only limited to dealing with the problem of area difference and calculating the price, the content of the current model text of the Commercial Housing Sales Contract does not need to be adjusted too much.

The current commercial housing sales contract is a model text supervised by Beijing Municipal Bureau of Land Resources and Housing Management. Among them, Article 4 presupposes three pricing methods: pricing by construction area, pricing by interior construction area and pricing by suite (unit). If the commodity house is pre-sold after 65438+ February this year, it can be directly priced according to the interior construction area. Accordingly, the standard contract text currently in use also has the option to confirm the area and deal with the area difference according to the pricing of the interior area. Therefore, the pre-sale of commercial housing after 65438+February 1 shall be priced according to the interior construction area in accordance with the provisions of the Measures for the Administration of Urban Real Estate Transfer in Beijing. However, in the standard text of commercial housing sales contract currently in use, there are corresponding options for pricing according to the interior construction area, and there is no need to make too many adjustments to the content of the current model text of commercial housing sales contract.

24. After sales according to the interior construction area, how is the "pool part" in Annex II of the contract reflected?

If the house is sold according to the interior construction area, the "Annex II: Composition Description of Shared Construction Area of Public Parts and Public Houses" in the commercial house sales contract is still an indispensable part of the house purchase contract. The "Annex II: Description on the Composition of Shared Construction Area of Public Parts and Public Houses" (hereinafter referred to as "Description") in the commercial housing sales contract has at least two meanings when priced according to the construction area. First, it can explain the composition of allocation, which is related to the total purchase price; Second, it is related to the data of * * * property rights in property rights registration. If the price of interior construction area is changed, the impact on the total purchase price will not be so direct, but which part of the owner has property rights is still a problem. Therefore, Annex II remains an indispensable part of the contract.

25. What supplementary terms should be added when signing a supplementary agreement?

The pre-sale of commercial housing is based on the interior construction area, and the area confirmation and area error treatment are based on the interior construction area. At this time, when signing the contract, the customer should have a constraint on the developer in the pool. What needs to be explained here is that the valuation according to the interior construction area does not mean that the developer will bear this part of the pool. In fact, developers will allocate the cost and even profit for this part of the pool to the unit price, which will inevitably lead to an increase in the value of the unit price of commercial housing, and buyers will have a psychological price for housing prices. The unit price is too high, which will inevitably affect sales. In this case, in order to reduce costs, developers may try to reduce the pool area as much as possible, if the pool is too small. The simplest thing is that if the stairs are too narrow, it will cause inconvenience in daily access and affect the quality of the property.

26. From a legal point of view, what are the risks of selling according to the interior construction area? How should buyers avoid it?

Everything has advantages and disadvantages, so does the pre-sale of commercial housing according to the interior construction area. The most direct possibility is to pay too much attention to the unit price of commercial housing and the situation of commercial housing itself, while ignoring the composition of shared construction area of public houses and public houses. Many unsatisfactory places, such as the lobby, elevator car and stairs, are too small and narrow to live in, which are the risks of pre-sale of commercial housing according to the interior construction area. When buying a house, if possible, the buyer should write the seller's promises about these aspects into the supplementary terms of the contract, which is one of the ways to avoid risks and ensure the quality of the building.

27. Is it necessary for the purchaser to agree with the developer on the pool area and property ownership in the annex to the contract?

There is no need to agree on the pool area and property right with the developer in the annex to the contract.

First, Article 18 of the Measures for the Administration of Commercial Housing Sales stipulates that "if the price is calculated according to the interior construction area, the construction area and the existing construction area shall be indicated in the commercial housing sales contract." In Article 3 of the sales contract for demonstration commercial housing, data such as the construction area agreed in the commercial housing contract, interior construction area, shared construction area of public parts and public housing shall be filled in separately. Therefore, there is no need to agree on the size of the pool area with the developer in the annex.

Second, the real estate license clearly indicates the construction area of the purchased house, the interior construction area, and the shared construction area between public houses. Therefore, the buyer does not need to agree on the property right of the pool area with the developer in the annex.

28. After the sale according to the interior area, how should the property right of the pool area be defined in law? Do owners enjoy the same rights and interests in the pool area and in the sales according to the construction area?

A total of * * building area is * * * property right. Article 18 of the Measures for the Administration of Commercial Housing Sales stipulates: "The construction area of commercial housing consists of interior construction area and apportioned construction area. The interior construction area is independent property right, and the shared * * * construction area is * * property right. The buyer enjoys rights and assumes responsibilities in accordance with the provisions of laws and regulations. " According to the provisions of this article, the Buyer enjoys the property right of * * * for the apportioned part of the * * construction area. Sales according to the interior construction area and sales according to the construction area, the owners enjoy the same rights and interests in the pool area.

29.65438+February 1 What should I pay attention to when changing hands?

The Measures for the Administration of Urban Real Estate Transfer in Beijing only stipulates that the pre-sale of commercial housing should be priced according to the interior construction area, that is, if it meets two conditions, it should be priced according to the interior construction area: first, pre-sale; The second is commercial housing. The transfer of purchased commercial housing does not stipulate that it must be priced according to the interior construction area, so it basically has no impact.

30. After the pre-sale of commercial housing according to the interior construction area, is there any change in the measurement method of construction area according to relevant laws and regulations?

Article 18, paragraph 2, of the Measures for the Administration of Commercial Housing SalesNo.: "The construction area of commercial housing consists of the interior construction area and the shared interior construction area." That is, the construction area consists of the interior construction area and the shared existing construction area. These two parts need to be clearly stated in Article 3 of the commercial housing sales contract. * * * The apportioned construction area is calculated according to Annex II.

3 1. What is the legal basis for charging property management fees according to the interior construction area after buying a house?

Property management fees are composed of many parts, which can be referred to the Interim Measures of Beijing Municipality for Property Management Service Fees in Ordinary Residential Areas. At the end, there is a statement that "square meters in this standard refer to the construction area". There are also provisions in Beijing Residential District (Ordinary) Entrusted Management Charge Standard (Trial), in which square meters refer to the construction area. But what needs to be explained here is that some fees are charged by households, and only the items charged per square meter are charged according to the construction area.

About surveying and mapping

32. Why is it less feasible for buyers to ask people to measure the shared construction area separately?

It is not feasible for buyers to ask people to measure the total construction area by themselves. There are three reasons: ① According to the existing laws of our country, the calculation method and procedure of apportioned construction area are very complicated. If buyers want to know the shared floor area of their houses, they should not only know the data of the whole building, the shared floor area and the floor area of each suite, but also know whether some components of the whole building have been shared repeatedly and how many times. It is basically impossible for property buyers to understand these data or situations. According to the laws and regulations of real estate surveying and mapping in China, buyers should pay surveying and mapping fees when surveying and mapping again, but the surveying and mapping fees are charged on the basis of surveying and mapping area. Under normal circumstances, the construction area of commercial housing ranges from several thousand square meters to tens of thousands of square meters or even more. For property buyers, this is not a small expense. (3) Because there is no administrative coercive power and judicial coercive power, developers and other property buyers in the same building have no obligation to cooperate with surveying and mapping. Therefore, once the developer or other property buyers do not cooperate with surveying and mapping, even if the property buyers have the money to ask someone to measure the shared floor area, the surveying and mapping behavior may end in vain because they cannot obtain actual data or information.

33. Can the area measured by the buyers themselves be used as the basis for property right registration?

If the developer has no objection, yes. According to the Notice of Beijing Land and Housing Management Law [2003] No.531on Promoting the Marketization of Commercial Housing Surveying and Mapping, if the buyer thinks that the area surveying and mapping data issued by the developer is inaccurate, he can entrust a qualified surveying and mapping unit to retest the purchased house area and inform the developer of the retest result. If the developer has no objection to the surveying and mapping results provided by the buyer, the buyer and the seller can directly settle the house payment according to the surveying and mapping results provided by the buyer. If the developer has any objection to the surveying and mapping results issued by the purchaser, then the surveying and mapping results issued by the purchaser cannot be directly used for property right registration.

34. How should the purchaser entrust the real estate surveying and mapping agency to conduct area surveying and mapping?

The purchaser can entrust a real estate surveying and mapping unit with corresponding qualification grade to conduct area surveying and mapping on its own in the city real estate surveying and mapping service hall. When entrusted, the purchaser shall pay the surveying and mapping fees according to law and sign a written contract with the real estate surveying and mapping unit on surveying and mapping matters. The contract shall include the basic information of the surveying and mapping project, the completion period, the charging standard, the quality requirements of the results, the dispute settlement method and so on.

35. What is the difference between the predicted area and the measured area indicated by the developer?

According to the "Measures", developers should publicize the surveying and mapping results of the area (including construction area, interior construction area and shared public construction area) to buyers twice before the pre-sale of commercial housing and after the completion of commercial housing. The nature of surveying and mapping results in these two stages is quite different. The former is the forecast data of the pre-sale area of commercial housing projects, calculated according to the design drawings; The latter is the data of field measurement of the area and location of houses that have been completed and accepted by relevant departments, and it is the data of property right registration. Whether the predicted data are consistent with the measured data, the error rate is an important criterion for buyers to investigate whether the developer has breached the contract on the area issue.

36. How to charge for commercial housing surveying and mapping?

The charging standards for surveying and mapping projects undertaken by commercial housing surveying and mapping units shall be implemented in accordance with the relevant provisions of the Price of Surveying and Mapping Engineering Products promulgated by the State Bureau of Surveying and Mapping in 2003. According to this provision, different types of commercial housing surveying and mapping fees are different. Among them, the planned household price of surveying and mapping residential houses is 1.36 yuan/m2, and that of office buildings is 2.04 yuan/m2.

37. What if there is a contradiction between the surveying and mapping results provided by buyers and those provided by developers?

If there is a contradiction between the surveying and mapping results provided by the purchaser according to legal procedures and those provided by the developer, then the purchaser can negotiate with the developer. If negotiation fails, a lawsuit may be brought to a people's court or an arbitration institution for arbitration according to law. When the people's court conducts a trial or an arbitration institution conducts arbitration, if the buyer takes his own surveying and mapping results as evidence to support his request, but the developer does not approve it, the buyer and the developer may entrust a qualified surveying and mapping unit recognized by both parties to conduct retest; If it cannot be entrusted, the people's court may designate qualified surveying and mapping units to conduct surveying and mapping again. The surveying and mapping results of re-surveying and mapping can be used as the basis for the judgment (ruling) of the court or arbitration institution.

38. How does the buyer supervise the surveying and mapping unit to carry out surveying and mapping according to law?

At present, China's laws do not give administrative organs the right to supervise surveying and mapping activities of surveying and mapping units. Therefore, the mapping behavior of surveying and mapping units depends more on the supervision of the entrusting party (buyers or developers). The "Measures" clearly stipulate that surveying and mapping institutions shall conduct actual measurement in accordance with the relevant technical specifications of the state and this Municipality, and be responsible for the quality of surveying and mapping results. The above provisions are an important legal basis for the buyer to supervise surveying and mapping units. Accordingly, the buyer can clearly stipulate the liability for breach of contract or compensation in the surveying and mapping contract signed with the surveying and mapping unit, such as surveying and mapping data errors and quality problems of surveying and mapping results, in order to safeguard their legitimate rights and interests.

39. Which units can accept the area mapping entrusted by the buyers?

According to the Notice of Beijing Land and Housing Management Law [2003] No.531on Promoting Marketization of Commercial Housing Surveying and Mapping, the following 26 surveying and mapping units can be entrusted by buyers or real estate development enterprises to conduct area surveying and mapping. They are: Beijing Real Estate Surveying and Mapping Institute, Dongcheng District Land Resources and Housing Administration Surveying and Mapping Institute, Xicheng District Real Estate Surveying and Mapping Institute, Chongwen District Land Resources and Housing Administration Surveying and Mapping Team, Xuanwu District Real Estate Surveying and Mapping Institute, Chaoyang District Land Resources and Housing Administration Surveying and Mapping Team, Haidian District Land Resources and Housing Administration Surveying and Mapping Team, Fengtai District Housing Management Service Center Surveying and Mapping Team, Shijingshan District Land Resources and Housing Administration Surveying and Mapping Team, Shunyi District Land Resources and Housing Administration Surveying and Mapping Institute, Tongzhou District Land Resources and Housing Administration Surveying and Mapping Institute, Daxing District Land Resources and Housing Administration Surveying and Mapping Institute, (Fangshan District) Tiandi Hongtu Surveying and Mapping Institute, Mentougou District Land Resources and Housing Administration Surveying and Mapping Institute, Huairou District Real Estate Surveying and Mapping Institute, Yanqing County Real Estate Surveying and Mapping Institute, Miyun County Real Estate Surveying and Mapping Institute, Pinggu District Real Estate Surveying and Mapping Institute, Beijing Huaxia Jingwei Surveying and Mapping Technology Co., Ltd., Beijing Dingchun Dezheng Surveying and Mapping Center, Zhongxing Zhao Ye Housing Area Surveying and Mapping Company, Beijing Xinxing Huaan Real Estate Engineering Surveying and Mapping Office, Beijing Changfang Real Estate Surveying and Mapping Technology Service Co., Ltd., Beijing Jinghengshi Surveying and Mapping Technology Co., Ltd., Beijing Shouyijia Real Estate Brokerage Center, and Beijing Housing Area Measurement Station.

E about other related expenses.

40. After the pre-sale of commercial housing is priced according to the interior construction area, will the property management service fee payable by the purchaser change?

No, according to the Measures of Beijing Municipality for Charging Property Management Services in Economically Affordable Housing Communities (Trial) and local property management practices, property management services are charged according to the construction area. According to the nature and characteristics of services provided by property management enterprises, the charging standards are subject to government pricing, government guidance pricing and operator pricing respectively. It can be seen that the amount of property management service fee will not change because the pre-sale of commercial housing is priced according to the interior construction area, but only related to the construction area of the house purchased by the purchaser and the standard of property service fee in the community.

Hope to adopt, thank you.
