Bedikas Chometz when Traveling for Pesach

270 Bedikas Chometz when Traveling for Pesach 

If a person is leaving on Erev Pesach to be somewhere else for Pesach and is selling their entire house to a goy for the duration of Pesach, they should make sure to exclude one room, and do Bedikas Chometz there on the night of Bedikas Chometz. If a person is leaving before the night of Bedikas Chomtez, they should do Bedikas Chometz after they arrive in the place where they are on the night of Bedikas Chometz. If they are staying at someone else’s house and have their own chometz there, they can do Bedikas Chometz in their assigned room with their own chometz. If they do not have their own chometz, they are not obligated in the mitzvah of Bedikas Chometz in their room at their host’s home. If the guest wishes to be strict, they can acquire their own chometz, bring it into their room, and then do Bedikas Chometz. If doing so is impossible, some opinions suggest that the guest can make a kinyan with the baal habos, owner of the house, and acquire their room through it; however, in order to be able to make a brachah, it would not be that simple, and consequently it is best that the guest be yotzei the brachah from the baal habos. Another option is for the host to do Bedikas Chometz in the guest’s room as in the rest of the house; even if the guest has their own chometz there, the baal habos can be their shliach, representative.
