What are the calculation rules of real estate surveying and mapping area?

I suggest that your friends know about the Standard Specification for Real Estate Measurement in People's Republic of China (PRC), which contains the legal requirements for real estate measurement. You can search this specification online and have a look.

1, the property measurement standard specifies the contents and basic requirements of urban property measurement, and is applicable to the property measurement of cities, towns, built-up areas, industrial and mining enterprises and institutions outside built-up areas, and adjacent residential areas. Real estate survey in other areas can also be implemented with reference.

2. In the real estate measurement standard, the accuracy is evaluated by the error as the standard, and the double median error is the tolerance.

3. The relative terminal error of adjacent basic control points shall not exceed 0.025M

4. The median error of the characteristic points on the real estate framing plan measured by simulation method and the points adjacent to the control points on the map shall not exceed 0.5 mm..

5. The median error of real estate elements and features measured by field data collection or field analysis relative to adjacent control points is less than 0.05m..

6. When using the existing coordinates or existing maps to develop the real estate subgraph, the development error shall not exceed 0. 1m on the map.

What's the new policy for housing area calculation?

1. According to the use function, the housing area is generally divided into direct use and indirect use. Direct use area is divided into internal use area and shared use area, and indirect use area includes wall use area, property use area and decoration use area.

2. In the direct use area, the internal use area includes: master bedroom, second bedroom, baby room, bathroom, utility room, living room, kitchen, dining room, gym, etc. The usage of these areas is the sum of the area results obtained by multiplying the length and width of the house. The balcony area is calculated according to the difference between closed and unsealed, and the closed area is included in the usable area. On the contrary, it is half the area.

3. In the direct use area, the common area includes: buildings, elevators, power distribution rooms, garbage rooms, public areas, etc. The shared use area of each household is divided by the number of users in the same area.

4. Indirect use area includes: the wall area is divided according to the existence and exclusive use of * * *, half of the wall area used by * * is included in the house use area, and all the wall areas used by * * are included in the use area; The use area of the property has a guard room at the entrance of the community. The area of the guard room is shared equally by the residents of the community, and the area falling on each household is generally small; Decorative areas include green areas, etc.
