Illegal buildings mainly include:
1, a building built without application or approval and without obtaining a construction land planning permit and a construction project planning permit;
2, unauthorized changes in the construction project planning permit provisions of the construction of buildings;
3. Do not change the nature of the building;
4, after the construction of temporary buildings over the period of validity has not been removed into permanent buildings;
5. Buildings constructed by forging relevant materials to defraud the permission of the competent department.
In recent years, the state has strictly controlled the red line of grain land, and any construction on grain-producing land will be strictly controlled. Building a sheepfold on the responsible land has changed the nature of the use of the responsible land, without applying to the relevant departments and obtaining permission in advance. For illegal buildings in rural areas, it is possible to be demolished.
