Mezuzah in AirBnB
Question
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 .
