Can the property install billboards on the roof of the community? Who has the right to set up billboards on the roof of residential areas?

Who owns the right to set up billboards on the roof mainly depends on who owns the roof. There is an agreement on the right to use the external wall and roof in the commercial housing sales contract (model text). Different contents of the agreement have different legal consequences. Specifically, there are two situations: first, if the buyers and developers agree that the right to use the roof and external walls belongs to all owners, then the developers must obtain the consent of all owners and owners' committees if they want to install billboards on the roof or other external walls. Second, if the property buyers and developers agree that the right to use the roof and external wall belongs to the developer, the developer does not need to obtain the consent of the owners and the owners' committee when installing billboards.

In any case, the property management company has no ownership of the roof and external wall and has no right to allow others to use it without authorization.
