Does the concept of Hasagas Gevul apply to a Chabad House? May one open a second Chabad house in the same city as a current one:^[1]

There are restrictions against opening a new Shul if this will infringe on the membership of another Shul in the vicinity, and the salary of its leaders.[2] Accordingly, there are restrictions against opening a new Beis Chabad if this will infringe on the income of another Beis Chabad in the vicinity.^[3]

The Rebbe on opening a new Beis Chabad which infringes a currently established Chabad house:^[4]

Free translation: It is possible for one to build a house of Torah, a Beis Chabad, but it will not be a place where Hashem dwells. How can this be? If the home is not built according to Shulchan Aruch, and transgresses the laws of Hasagas Gevul, as this home is a Mitzvah Haba Beaveira. Hasagas Gevul causes the victim to cry to Hashem against the fact that his income was infringed and the commotion he makes prevents the Shechina from dwelling in the others home. Its obvious that everything involved in establishing a Beis Chabad must be in accordance to Shulchan Aruch, Toras Moshe, without any infractions of Hasagas Gevul. So while we encourage the opening of many new Batei Chabad, it must be done with the sensitivity not to infringe on the territory of others. At the same time, however, we must make clear the following: There are matters to which Hasagas Gevul does not apply, such as teaching Torah and the like. Accordingly, we need to negate the mistake of the fools who cry foul play if another Jew desires to open a Beis Chabad due to the fact that he will steal his right of putting Tefillin onto people, or that he will diminish his honor and respect in the eyes of the public. Their foolishness is so great, that they don’t suffice with just shutting down the other person’s operations, but demands that he leave the city all together, thinking that the entire city and its suburbs all belong to him. Its obvious that regarding all the above, it must be given to a Rav to arbitrate according to Halacha, and the problems all begin when people take the law into their own hands and make their own rulings.
