The exterior wall is punched at will, and the property requires rectification. Is there any law in the country?

Don't punch holes at will, which may damage the load-bearing structure of stairs.

According to Article 5 of the Measures for the Administration of Residential Interior Decoration:

The following acts are prohibited in residential interior decoration activities:

1. The main body and load-bearing structure of the building are changed without the original design unit or a design unit with corresponding qualification grade;

2. Change rooms or balconies without waterproof requirements into bathrooms and kitchens;

3. Enlarge the size of the original doors and windows of the load-bearing wall, and dismantle the brick-concrete wall connecting the balcony;

4. Damage the original energy-saving facilities of the house and reduce the energy-saving effect;

5. Other behaviors that affect the safety of building structure and use.

The term "building subject" as mentioned in these Measures refers to the structural structure of building entities, including roofs, floors, beams, columns, supports, walls, connecting nodes and foundations.

The term "load-bearing structure" as mentioned in these Measures refers to the main structural members and their connecting nodes that directly transfer their own weight and various external forces to the foundation, including load-bearing walls, uprights, columns, frame columns, piers, floors, beams, roof trusses and suspension cables.

Wang Xiaodong, an architect of Beijing Architectural Design Institute, told Xinbao that as a "load-bearing wall" system, all stressed walls are not allowed to be demolished at will. He stressed that no matter whether it is a masonry load-bearing wall or a reinforced concrete load-bearing wall, any demolition is beyond the control of the home improvement company.

Because conditional demolition and modification must meet the following conditions: the original structural engineer reviews the design or authorizes it, and other structural engineers agree to review the design. Under certain conditions, according to the reconstruction and reinforcement construction drawings, under the guidance of construction departments and personnel with professional reinforcement construction qualifications, through remedial measures such as strengthening relevant parts, holes can be appropriately opened in some allowable parts of the load-bearing wall.

"The load-bearing wall bears many functions such as load-bearing and shear resistance. At present, many events have confirmed that any unscientific demolition and reconstruction will cause irreparable disasters to the building. "

According to Peng Hua, Ph.D. in Mechanics, Institute of Geomechanics, China Institute of Geology, during the Wenchuan earthquake, it was found that some buildings with good seismic performance collapsed in the middle, while other units were intact. The reason is that a resident destroyed the load-bearing wall during renovation, which reduced the seismic performance. The semi-collapse of a three-story building in Shanghai more intuitively illustrates the serious harm of decoration destroying the load-bearing wall.

At the same time, he reminded that although non-load-bearing walls do not play a major load-bearing role, some non-load-bearing walls are secondary load-bearing components and are extremely important supports for load-bearing walls. Take a 6-storey house as an example, the non-bearing wall in the bottom floor house should bear the weight of the upper 5-storey wall. This kind of non-bearing wall is usually a seismic wall in design. If there is an earthquake, these non-bearing walls will bear the earthquake force together with the bearing walls.
