Translation:Shulchan Aruch/Orach Chaim/243

1. One shouldn’t rent out his bath house to a non-Jew because the bath house is known to be his. The non-Jew will do work with it on Shabbat. The average bath house isn’t rented out according to a percentage (meaning the worker takes a percentage of the profits). People will say all the profits go to the Jew and wages go to the non-Jew, and as a result the non-Jew is doing work as an agent of the Jew. But to rent out a field is allowed, since it’s common to rent out a field according to a percentage, even though people know it’s the Jew’s field. They will say the non-Jew is working according to a percentage so he’s working for his own sake. An oven is treated like a bath house in this sense. A millstone is treated like a field in this case. RAMA: Even if a gentile receives only a third or a fourth of the profits, and the Jew receives a benefit from the gentile’s work on Shabbat, it’s permissible to set up this arrangement, since the gentile is working for his own sake.

2. Even for a bath house or an oven: if he rents it out year after year and this matter is publicized that the workers are not getting wages, rather they are rented, or similarly if the custom of the place is that most people rent or stipulate that the profits go according to percentages, then it’s permissible to rent it out to a non Jew or to have profits go according to percentages. RAMA: Even in a place where it is forbidden, if the Jew is hired to work the bath house or oven by a gentile, then he rents it out to a gentile, it is permissible, since the property isn’t recognized to be owned by the Jew. Similarly, if there is a bath house in living quarters and only those that live there use the bath house, and they know that they hired a gentile, then it is permissible. If one transgressed, and rented it out in a situation that is forbidden, some authorities say the rent money is permissible, others say forbidden.
