Legal analysis: In fact, as far as the current policy is concerned, there is no clear stipulation to build iron houses, but we can judge from the definition of illegal buildings. In any of the following circumstances, it is regarded as an illegal building, as follows:

1, completed before approval

First of all, it is certain that new or rebuilt houses will be considered as illegal buildings without the approval of relevant departments and construction permits, so building iron houses in self-built houses without approval does not meet the policy requirements.

2, not according to the provisions of the examination and approval of the construction

When the owner of the building is approved in accordance with the relevant regulations and passes the construction application, he will obtain a construction planning permit or a temporary construction permit. The certificate will generally indicate the area and address of the iron house to be built, and the owner needs to build it according to the information on the certificate. If the construction is not carried out in accordance with the examination and approval provisions, it shall be regarded as illegal construction. The construction of iron houses

3. Occupy the planned land.

As far as rural land is concerned, there may be land planned for public construction in some areas, and no one may occupy such planned land to build his own house, otherwise the house will be regarded as illegal.

4. Changed the nature of the land.

Without special circumstances, the nature of rural land cannot be easily changed. As far as the land occupied by self-built houses in rural areas is concerned, it is used for housing construction, that is to say, iron houses built by self-built houses shall not be used for non-housing construction, such as building a factory building with business nature, otherwise it will be considered as illegal buildings.

5. Turn temporary buildings into permanent buildings. Some people apply to build a tin house and apply for temporary construction. Since it is a temporary building, it has a certain period of time and cannot become a permanent building, otherwise it will be considered as an illegal building. In addition, iron houses that violate the relevant provisions of laws and regulations are also illegal buildings.
