Most urban houses are designed and built by professionals.
Generally, the buildings on the residential land are residential buildings, and the supporting houses in the residential community, such as guard room, power distribution room, independent garage, etc., can be investigated as non residential buildings.
In fact, except that a few remote areas still retain the mode of mutual assistance building, it is possible to adopt this method for houses built earlier.
If the basement is part of a building, investigate according to one building; If there are multiple independent buildings on the basement, the basement can be divided into these buildings as appropriate, and the total area can be accurate.
If the large chassis is connected with multiple towers, and multiple towers are obviously independent, separate investigation can be carried out.
(3) For the attic, refer to the relevant provisions in the code for design of residential buildings: when using the space in the sloping roof as the bedroom and living room (Hall), the indoor clear height of one-half of the area shall not be less than 2.1m.
Buildings on state-owned land belong to urban housing construction, while those on collective land belong to rural housing construction.
Self construction refers to the construction by farmers themselves or with the assistance of relatives, friends and villagers.
Judging whether “professional design and construction” can not simply be based on whether there are design and construction data.
10、 How to determine the construction mode of rural houses? The construction methods of rural houses include self construction, construction craftsmen construction and qualified construction teams construction.
4、 How to judge whether the building is “professionally designed and built”? Professional design and construction means that the building is constructed by survey units, design units, construction enterprises and engineering supervision units with corresponding qualifications under the unified coordination of the construction party.

Don’t judge them as non professional design and construction at will.
According to the normal investigation of non residential requirements, the size of the map spot can remain unchanged, but there must be (that is, it shows that there are buildings there); When there are multiple entrances and exits with spots, other entrances and exits shall be treated as “no investigation required”.
If some houses are schools and hospitals built around 2000, they are judged as non professional design and construction, which is unreasonable.
It is the main way of building houses in rural areas.
Some rural houses constructed according to the standard atlas should also be regarded as professional design and construction.
and corresponding uses of the non residential part shall be described in the remarks, such as commercial and residential mixed buildings.
what should be investigated in the “seismic structural measures” of rural houses? Different structural types of buildings have different requirements for seismic structural measures.
If it is non residential, select “comprehensive building” for building purpose, and select “residential and Commercial comprehensive”, “office and Commercial comprehensive” and “other” in the secondary option of the system according to the main purpose.
Early buildings may not be able to obtain design and construction data.
1、 How to define urban housing construction and rural housing construction? The main basis for defining urban and rural housing construction is the nature of land.
The investigation on seismic structural measures of rural houses mainly includes the contents listed in the table below.
7、 How to investigate the basement (garage)? If it is an independent basement (there are no buildings on it), the map spot at one of the entrances and exits shall prevail.
3、 How to determine the “building use” of multi-purpose buildings? According to the nature of construction land, first distinguish whether the building is residential or non residential.
8、 How to investigate large chassis multi tower buildings? If the large chassis and multiple towers are structurally independent of each other, they shall be investigated separately.
6、 For buildings with non-standard floors, how to determine the number of floors, building area and building height? (1) For storage rooms and garages with a floor height of less than 2.2m on the ground floor of buildings, the number of floors and area shall not be included, but the building height shall be included.
If it belongs to residence, it shall be investigated according to the requirements of residence.
At this time, the large chassis can be distributed to each tower as appropriate; If the large chassis is a whole, multiple towers are multi-storey, the area is small and the structural form is the same, it can be filled in according to one building.
2、 How to define residential and non residential? The distinction between residential and non residential depends on the nature of construction land.
The general decoration or repair that has no impact on the main structure is not included in the scope of transformation, such as ordinary painting, replacing doors and windows, modifying water and electricity, etc., but the modification such as increasing load, dismantling or damaging some load-bearing structures during decoration is considered to have been transformed.
When filling in, you need to inquire from many parties and consult relevant materials.
Whether the building has been formally designed and constructed can be used as the main basis for judgment.
The construction of qualified construction team refers to the construction team with construction qualification invested and hired by farmers..
Other buildings in the nature of construction land are non residential, which are distinguished by purpose, such as industrial buildings, commercial buildings, office buildings, comprehensive buildings, etc.
“Expert analysis series” aims to invite experts to respond to the problems encountered in the investigation of housing construction and municipal facilities.
No matter how it is filled in, the total construction area shall remain unchanged; If the structural type of each part is different or the construction age is different, it needs to be investigated separately.
If this basic condition is not met, it can not be regarded as a formal bedroom or living space, but as an attic, not counting the area and floors, and the height of the house is calculated to one-half of the height of the attic.
At this time, the building area is the sum of the total area.
It is usually in the form of a small team of experienced craftsmen with several small workers.
(2) For duplex housing construction, it shall be calculated according to the number of floors and area registered by relevant departments; If it is a duplex house added by the owner (or adding mezzanine), it shall be calculated according to the actual situation after transformation, and the option of “transformed” shall be filled in.
5、 How to define whether housing construction has been transformed? “Whether it has been transformed” mainly refers to whether there are changes in the use, load increase, load-bearing structure change and so on.
State owned farms located in rural areas generally belong to state-owned land, and their buildings should be investigated according to urban housing buildings.
Construction by craftsmen refers to the construction by craftsmen who are invested and entrusted by farmers.
The non residential part of the building shall not be included in the number of residential units, and the number of floors, area, etc.
