No Eruv in Crown Heights
There is no eruv in Crown Heights that may be relied upon. The Crown Heights Rabbonim have ruled repeatedly that carrying in the neighborhood streets is forbidden on Shabbos and Yom Kippur. A stroller, key, siddur, bag, food, or any other object may not be carried on the strength of the eruv that has been publicized.
The psak of the Crown Heights Rabbonim
Rabbi Aharon Yaakov Schwei and Rabbi Yosef Yeshaya Braun ruled that carrying in the streets of Crown Heights is “absolutely forbidden,” and that the structure presented as an eruv is “treated as nonexistent” (2 Iyar 5776).
Rabbi Avrohom Osdoba and Rabbi Shlomo Yehuda Halevi Segal gave the same instruction in their joint ruling: “There is no halachically valid eruv anywhere within the boundaries of the neighborhood.” They applied the prohibition to both Shabbos and Yom Kippur (Sivan 5776).
The ruling has remained the same as different arguments have been raised. Rabbi Osdoba and Rabbi Braun wrote that the position of the neighborhood's Rabbonim, including Rabbi Schwei and Rabbi Zalman Shimon Dworkin, was a categorical rejection of the proposed eruv. They later addressed the claim that exterior walls enclose much of the area and ruled that it made “no change whatsoever” to the prohibition on carrying (20 Teves 5783).
In practice: on Shabbos it is absolutely forbidden to carry in the streets of the neighborhood.
Carrying on Shabbos and Yom Kippur
Hotza'ah is not limited to carrying a valuable object or walking a long distance. Bringing a key from a building into the street, pushing a stroller, taking a siddur to shul, or walking with an object in a pocket can all involve the melacha. Carrying four amos within a reshus harabim is also prohibited even when no doorway is crossed.
A child or a non-Jew is not a routine substitute for an eruv. The halachos of chinuch, amirah l'akum, illness, and genuine need have their own limits; they do not provide a general arrangement for ordinary weekly carrying. Medical, safety, and mobility needs must be handled according to the circumstances, with advance planning wherever possible.
What makes a city eruv valid
A city eruv depends on several separate parts of halacha. The streets must first be classified. A reshus harabim cannot be enclosed in the same manner as an ordinary residential area. The boundary itself must then be valid along its entire route, including every wall, fence, opening, pole, wire, and tzuras hapesach used to complete it.
The physical boundary is only one part. Depending on the area, eruv chatzeiros or shitufei mevo'os may be required, together with sechiras reshus where applicable. Regular inspection can find a broken wire or a new gap, but the halachic status of the streets and the original enclosure must be settled before those inspections begin.
The proposed boundary around Crown Heights
The boundary publicized for Crown Heights relies heavily on existing walls and omed merube, including structures outside the neighborhood. The calculation depends on what can serve as a halachic wall, where each opening begins and ends, and whether the different sections form one continuous enclosure.
The Crown Heights Rabbonim did not accept the proposed exterior walls as establishing an eruv for the neighborhood. Their ruling states that the walls made “no change whatsoever” to the prohibition on carrying.
The Rebbe on city eruvin
In his letters on city eruvin, the Rebbe called for the local conditions to be investigated by a Rav with particular expertise in these halachos. He also warned against publicizing an eruv, since people who become accustomed to carrying may continue if the eruv later becomes invalid.
Concerning Crown Heights, Rabbi Yehuda Leib Groner conveyed the Rebbe's words: “I will not permit an eruv to be made here in the neighborhood.” The Chitrik family related the same position in the name of Rabbi Hirshel Chitrik, based on his yechidus with the Rebbe.
Rav Moshe Feinstein and the New York eruvin
Rav Moshe Feinstein wrote at length about reshus harabim, shishim ribo, and the proposed eruvin in Manhattan and Brooklyn, including Flatbush and Boro Park. He ruled that the proposed eruvin he addressed could not be relied upon and joined public rulings against establishing them.
Rav Moshe also discussed the effect of public carrying on visitors who later return to a place without an eruv. Crown Heights receives residents and guests from Lubavitch communities around the world, many of whom return to places where no eruv is accepted.
