Building with Mobile Toilet
Adding a mobile toilet to a building may involve illegal construction and is considered an unauthorized structure.

Public Area Attributes
The rooftop terrace belongs to the common area shared by all homeowners in the residential community and is not private space for any individual. According to relevant laws and regulations, the planning and use of public areas must adhere to the collective will of all homeowners and the overall planning of the community. No individual has the right to unilaterally change its purpose or engage in construction.
Unauthorized Construction Activities
Constructing a mobile toilet on the rooftop terrace without obtaining any construction planning approval constitutes unauthorized construction or renovation. According to Article 40, Paragraph 1 of the Urban and Rural Planning Law of the People's Republic of China, any construction activity must obtain a construction project planning permit in accordance with the law. Unauthorized construction without such a permit is considered illegal.
Hazards of Illegal Construction
- Encroachment on Public Resources: The installation of a mobile toilet occupies public space originally belonging to all homeowners, infringing upon the legitimate rights and interests of other homeowners. This may prevent other homeowners from using the terrace for leisure or drying activities as usual.
- Safety Risks: Such unauthorized structures may pose safety risks such as falling objects and structural overload. The installation of a mobile toilet may alter the original structure of the rooftop, increasing its load and threatening the structural safety of the building. Additionally, if the mobile toilet is not securely installed, it may fall during adverse weather conditions such as strong winds or heavy rain, endangering the lives of pedestrians below.
Legal Consequences
For such illegal construction activities, relevant authorities have the right to order removal within a specified period and impose fines. If the structure is not removed within the deadline, the authorities may legally enforce its removal, with the costs borne by the violator. Therefore, before adding a mobile toilet to a building, it is essential to understand relevant laws, regulations, and community planning, and obtain legal approval to avoid unnecessary legal risks and economic losses due to illegal construction.
