Mezuzot in Places of Business?

Question:
Does one install mezuzot on the doorways of one's business?

Answer:
We do not answer questions of practical halakhah. I suggest that you consult with a halakhic authority.
For your own theoretical knowledge, I can tell you it seems that while the question appears to be dependent on an argument mentioned in the Babylonian Talmud (Yoma 11a), the present day consensus seems to be that mezuzot should be put up in places of business – though, possibly without the recital of the usual blessing. This is based on the opinion found in Yoma (ibid.) and subsequently codified in the Shulhan Arukh (Yoreh Deah, chpt. 286, paragraph 1) that warehouses (such as) for wine or oil are obligated in mezuzah. I saw this ruling expressed in the work Pithe Mezuzot by Yisakhar Hazan [(Betar Ilit : Yisakhar Hazan), 5766] both in his commentary on the Shulhan Arukh’s laws of mezuzah entitled Pithe Mezuzot (see chpt. 286, notes 9-11) and in his summary of the laws of mezuzah entitled Bet Mezuzah (see chpt. 8, p.205-208). The same opinion is also expressed in the work Shaare Mezuzah by Shemuel Yosef Shtitsburg [(Bet Shemesh : Shemuel Yosef Shtitsburg, 2008)] – see chpt.6 paragraph 1 and see note 1 (ibid.) where he references the Arukh ha-Shulhan (chpt. 286, paragraph 28 – see also Arukh ha-Shulhan, ibid. paragraph 4).
