Extended data:

The emergence of roof greening aims at increasing the urban greening area, alleviating floating dust and urban heat island effect, purifying air and water, improving urban environment and improving living environment. Compared with the "illegal garden", the roof greening construction needs to be approved by the local planning department and recognized by the owners' Committee and the property.

Under the guidance of professional technical standards, ensure the safety of houses and the overall effect of buildings are not affected. At the same time, the roof greening applicant shall ensure that the greening results are enjoyed by all owners. Because roof greening involves public resources, it has certain public welfare attributes compared with "illegal gardens".

The reason why roof greening and "illegal garden" are controversial is that the applicant has transformed the public space without the permission of the relevant departments, and after the completion, it has avoided the public welfare attribute of roof greening and regarded it as private property, which violates the principle of * * * *. Due to the late start of roof greening in China and the lack of corresponding norms, there are great disputes in China on the responsible person, the division of property rights and the follow-up management of shared projects.
