Does the property have the right to require the windows to be unified?

Legal analysis: there is definitely no specific and separate legal provision, but it can be based on some administrative norms. For example, in the "Regulations on Building Quality and Safety", it is not allowed to change the external wall structure without authorization, and the window hole belongs to the external wall. There are also property management regulations, and the city appearance regulations will stipulate the city appearance. Even the community owners' convention is binding on the owners of this community. Furthermore, if changing windows affects the lighting, ventilation and heat insulation of neighbors, which constitutes infringement, the property, as a community manager, also has the responsibility of management.

Legal basis: Article 277 of the Civil Code of People's Republic of China (PRC). Owners can set up owners' meetings and elect owners' committees. The specific conditions and procedures for the establishment of the owners' congress and the owners' committee shall be in accordance with the provisions of laws and regulations.

The relevant departments of the local people's government and the residents' committee shall give guidance and help to the establishment of the owners' congress and the election of the owners' committee.
