Mezuzah in AirBnB
Question
A Jew is traveling abroad and renting a house from a non-Jew for three months. Is he required to place mezuzot on the doorposts? Additionally, if mezuzot are required, what should he do if during those three months he leaves the house for 10 days, during which the owner might rent it out to other people, most likely non-Jews?
Answer
Shalom!
Thank you for your question.
The Talmud tells us that “One who lives in a hotel in the Land of Israel, or one who rents a house outside of the Land of Israel is exempt from the mitzvah of mezuzah for thirty days. One who rents for longer than this is required to put up a mezuzah. However, one who rents a house in the Land of Israel is required to affix a mezuza immediately…” (Menachot 44a).
We see from here that one who lives a temporary residence outside the land of Israel does not require a mezuza. Under 30 days is considered to be temporary. For longer then 30 days a mezuza is required. So one needs to fix the mezuza from the begining of his stay with a beracha.
One should not leave the mezuzot in place during the brief rental to non-Jews. When refitting them one doesn't need to recite again a beracha .
