Thanks! The following is just for educational purposes for poster’s who never were aware of what is an ERUV boundary
This zone is, in effect, a 'spiritual estate', which exists alongside ordinary notions of 'real estate'. Of course, this spiritual estate exists through the construction of physical components, and that requires planning permission from the relevant authorities. Thus, while a notion of Jewish law, an Eruv cannot be brought about without approval being granted at general law.
