When installing elevators in old residential areas, we must abide by a series of regulations and requirements. The installation of elevators should not violate the urban planning, but should be carried out on the premise of retaining the greening and public welfare facilities in residential areas. It must be ensured that the installation process will not affect or damage the infrastructure such as fire fighting system, water, gas, electricity, drainage and sewage. In order to ensure safety and rationality, the scheme must be formulated by a qualified design unit before installation, and can be implemented only after approval by the relevant departments.
