If someone lives in an apartment building with other Jews, do they need to make an eruv chatzeiros (in short: have shared food stored somewhere to make it considered as though they all live there together) to be allowed to carry from their apartment to the hallway or to neighboring apartments when the city's eruv goes down (after a storm or the like)?

    If there are 2 or more Jewish families and at least one non-Jew. Why not? Commented Aug 30, 2020 at 9:43

    @DannySchoemann Why one non-Jew? That's not a necessity for eruv chatzeiros. That just makes them more complicated since you need some sort of sechiras reshus.

    Since the Breuer's community doesn't hold by the WH 'eruvin, many buildings on Bennett have their own Commented Aug 31, 2020 at 4:04

    Why is it assumed that every community must have an eruv that will only be down in an unusual situation? Commented Sep 2, 2020 at 15:06

The short answer is "Yes".

However, a premise in the question is erroneous. An ערוב חצרות is only necessary to carry from the common area into the private area. Therefore, without an ערוב חצרות, it is still permissible to carry within the hallway itself, and one could carry objects that remained in the common from the start of שבת within the common area such as playground toys. See O"C 366:1 & 372:1 and the משנה ברורה who explicitly permits this. See also באור הלכה on 372:1 about a מחלוקת with regard to items such as a scarf, coat or hat that were worn into the common area, and removed therein. However, one must be careful to then put them back on before entering the apartment.

NOTE: This is different than the strings and poles commonly used for encircling neighborhoods, colloquially called "eruvin". If the strings went down, then all carrying is prohibited even entirely within the public area, since there are no halachic walls. It is theoretically possible to have poles and strings without the ערוב חצרות, but that would probably be unlikely.

My grandparents used to live in such a building, where there was one other non-religious family in the entire building, so they never bothered trying to make an ערוב. It was our practice to follow the lenient opinion with regard to clothing worn into the hallway.

    The credibility of your answer would be raised if you could quote some sources for what you say. Even if you are unable to quote Shulchan Oruch, there are resources on the web that are helpful see for example halachipedia.com/… . Commented Sep 2, 2020 at 15:42
  • @Eliyahu Please see my edit. With regard to items worn, I was remiss in not knowing about the מחלוקת, but with regard to main contention it is implicit in the שו"ע,and explicit in the מ"ב Commented Sep 4, 2020 at 11:00
  • @JosephK.Strauss Thank you. I have fixed the premise of my question. (I'm not sure what you saw in the Shulchan Aruch in 368:1 though)

    @Eliyahu It should be 366. I fixed that. Good catch. Commented Sep 6, 2020 at 21:16
