They are not talking about dwellings only for "administering the territory", or they would have put a restriction in the ruling. Even if you could apply your twisted logic to the 4th GC, that part only applies to conflicts between independent countries.  Palestine has never been a country so there is no chance that 4th Geneva Convention even remotely applies. The 3rd part of Geneva conventions clearly distinguishes the two types of conflict and clearly states that 4th Geneva convention does not apply to cases like this.
If you really want to follow the law then educate yourself first then please don't cherry pick only the parts of the law you like.

UNSC resolutions, ....Even .the resolutions that have been passed against Israel are non-binding and require no action, and can be ignored.  However UN's own Article 80 of the UN charter that guarantees that land to Israel can't be ignored.
