Introduction to Eruv Chatzeirot for Buildings

On Shabbat, you may not carry items in a building (such as a condominium) owned by more than one Jew (even if the other owners are not religious), from a condo into the hallway or from the hallway into a condo unless:
  • There is an eruv around the building, or
  • You have made an eruv chatzeirot with all the other owners.
Note If none of the other owners are Jewish, you do not need to make an eruv.
Note If you do not normally rely on municipal eruvs, you should not carry outside your apartment (such as in the building's halls--even if your building is within a municipal eruv), unless the building has an eruv chatzeirot
