What law does it violate to build a building without approval?

The legal basis is as follows:

Article 76 of the Property Law stipulates: "The renovation and reconstruction of buildings and their ancillary facilities in residential areas shall be approved by the owners whose exclusive parts account for more than two-thirds of the total building area and more than two-thirds of the total number of people." Unauthorized construction is illegal in itself. At the same time, the Urban Planning Law clearly stipulates: "To build, expand or rebuild buildings, structures, roads, pipelines and other engineering facilities in an urban planning area, an application must be submitted to the competent department of urban planning administration with relevant approval documents, and the competent department of urban planning administration will issue a construction project planning permit according to the planning and design requirements put forward by urban planning." Land occupation is obviously a kind of construction behavior, which must be approved by the planning department in advance and go through the relevant formalities. Therefore, the act of "heightening" without authorization is illegal, and the heightening part is illegal construction.

In China's Property Law and General Principles of Civil Law, it is clearly stipulated that the infringement treatment and compensation for lighting and ventilation should be handled: "The neighboring parties of real estate should correctly handle the neighboring relations in terms of water interception, drainage, transportation, ventilation and lighting in the spirit of benefiting production, facilitating life, solidarity and mutual assistance, and fairness and rationality. If it causes obstacles or losses to the neighboring parties, the infringement shall be stopped. If it has caused the result of obstructing the normal life of others, it should be dismantled as soon as possible and restored to its original state. If it has caused economic losses to others, it should also compensate for the losses according to law. " Unauthorized "heightening" not only violates the neighboring rights of owners such as ventilation and lighting, but also violates the relevant provisions of the Urban Planning Law. Therefore, the construction should be stopped as soon as possible, the illegal buildings should be demolished and the original state should be restored.
