Prefabricated House on the Third-Floor Roof

Generally, it is not allowed to privately construct prefabricated houses on rooftops. From a legal perspective, this mainly involves the following three aspects of regulations:

I. Planning Permission Requirements

According to Article 40 of the Urban and Rural Planning Law of the People's Republic of China, constructing a prefabricated house on a rooftop is considered an act of adding a new building or structure. It is necessary to apply for and obtain a construction project planning permit from the competent urban and rural planning department. Unauthorized construction without such a permit is illegal and may face administrative penalties such as being ordered to stop construction, being required to demolish the structure within a specified time limit, and being fined. If the construction has already become a fact and no corrective measures can be taken to eliminate the impact, the relevant department has the right to carry out a forced demolition, and the costs associated with it shall be borne by the illegal constructor.

II. Supervision and Regulation of Construction Activities

Based on Article 2 of the Construction Law of the People's Republic of China, the construction of a prefabricated house on a rooftop falls within the scope of construction activities and must comply with mandatory standards for building safety, fire protection, earthquake resistance, etc. Construction without approval may be ordered to be rectified and fined for violating construction norms. If it involves altering the main structure or load-bearing structure of the building (such as cutting floor slabs or adding loads), it may also violate Article 5 of the Measures for the Administration of Interior Decoration and Renovation of Residential Buildings, which prohibits damage to the building structure. In such cases, the constructor may be required to restore the structure to its original state, compensate for losses, and may face administrative penalties in serious cases.

III. Rules for the Management of Common Areas

According to Article 7 of the Regulations on the Administration of Urban Adjacent Buildings, the rooftop is a common area of adjacent buildings. Its use must be jointly decided by all owners or approved by the property management company. Occupying the rooftop to construct a prefabricated house without the approval of the owners' meeting or written permission from the property management company may constitute an infringement on the common ownership rights of other owners. The constructor may be required to bear civil liabilities such as ceasing the infringement, removing obstacles, and compensating for losses. If the construction affects the safety of the building or public interests, other owners may file a lawsuit with the court in accordance with the law to request the demolition of the illegal structure.

Summary: Constructing a prefabricated house on a rooftop requires meeting the conditions of planning permission, building safety, and consent from the common owners simultaneously. Failure to meet any of these conditions is illegal. It is recommended that owners consult the local planning and housing and construction departments as well as the property management company before construction and go through the approval procedures in accordance with the law to avoid legal risks.
