Installation of Mobile Toilets in Houses

Whether it is legal to install mobile toilets in houses depends on specific circumstances and cannot be generalized.

I. Legality of Installation in Rental Houses If a mobile toilet is installed in a rental house, the act of adding a toilet without the consent of the lessor is generally illegal. According to Article 715 of the Civil Code of the People's Republic of China, if a lessee improves the leased property or adds other objects without the consent of the lessor, the lessor has the right to request the lessee to restore the property to its original state or compensate for losses. If the installation involves altering or adding to the structure of the house, such as converting a room without waterproofing requirements into a bathroom, it violates Article 5 of the Measures for the Administration of Interior Decoration and Renovation of Residential Houses (Revised in 2011). This article explicitly prohibits unauthorized alteration of the main structure and load-bearing structure of a building, enlargement of the original dimensions of doors and windows on load-bearing walls, removal of brick or concrete walls connecting balconies, and conversion of rooms or balconies without waterproofing requirements into bathrooms or kitchens without a design plan proposed by the original design unit or a design unit with the corresponding qualification level.

II. Legality Related to Building Safety and Approval If the installation of a mobile toilet is not approved by relevant departments or violates building safety standards, the installation act may pose safety hazards and constitute an illegal act. For example, if the installation of a mobile toilet involves electrical wiring modification or alteration of load-bearing structures, it must comply with building safety standards. Otherwise, it may lead to safety accidents due to structural instability or electrical failures. In addition, if noise, odors, or other issues arise during the installation process, affecting neighborly relations, disputes or complaints may be triggered, and penalties may even be imposed for violating the provisions of the Public Security Administration Punishment Law regarding "making noise to interfere with the normal life of others."

III. Suggestions for Legal Installation If a mobile toilet needs to be installed in a house, it is advisable to first consult and obtain consent from relevant right holders, such as obtaining written consent from the lessor for rental houses and ensuring compliance with property management regulations or homeowners' conventions for self-owned properties. At the same time, ensure that the installation act complies with building safety standards and relevant laws and regulations. When involving alterations or additions to the house structure, consult professionals or relevant departments to obtain approval and guidance, such as applying for renovation permits from the local housing and urban-rural development department or entrusting a qualified design unit to issue a renovation plan.
