In a Jewish-owned and -operated mifa'al (factory/business), there is a room that is designated for the non-Jewish workers where they can eat, rest, etc. The room is used for nothing else (not even for storage purposes). Does the room need a mezuzah?

  • pretty sure it does. what establishes the requirement is the fact that a Jew owns the building, I think

    Hi YMW and welcome to Mi Yodeya. This seems to fit better as a comment than an answer, though if you can expand on it or bring a source please do post an answer. I look forward to seeing you around the site. Sep 11, 2012 at 14:30
  • Yehoshua, would you please edit into the question your reason for mentioning eretz Yisrael, for assuming that that's relevant?

This site gives some excellent information about mezuzot and is worth browsing through. As you can see, from the part of it that I linked to, a room needs a mezuzah so long as it is either owned or rented by a Jew, whether or not it is a room in which people dwell.

The book reviewed here, by Rabbi Reuvain Mendlowitz, looks to contain a lot of excellent information on the question that you have asked as well, and will be available shortly.
