Question: I rented an apartment. When I moved in the owner did not have any mezuzos up. I bought my own for the apartment. When I left I took my mezuzos with me. Did I do something wrong?
Answer: I’m sure you’re a wonderful, well intentioned person, but to be honest with you, you DID do something VERY incorrect.
A house or apartment with no mezuzos up, which is owned by a Jew or will be rented to a Jew, is considered hazardous to enter. The Talmud (Bava Metzia 102a) tells us something frightening: “If one rents a house out to his fellow (Jew) it is incumbent upon the tenant to prepare a mezuzah for it. And when the tenant leaves (when the lease is terminated) He should NOT take the mezuzah in his hand and leave with it. And there was once an incident involving one who took his mezuzah in his hand and left (at the termination of his lease) and in the end he buried his wife and his two sons.
Tosefos explain (ibid. 101b) that is forbidden to take the mezuzah because mazikim (destructive spiritual forces) enter a home that has no mezuzah, and when one removes the mezuzah it is as if he himself brings harm to those who enter it afterwards (and are put in harms way). The Ritva explains the man in the incident was punished measure for measure, since he endangered his fellow by removing the protection afforded by the mezuzah, he himself suffered grievous losses.
So, one must never ever leave a home owned by a Jewish landlord without a mezuzah (Yoreh De’ah 291:2) even if the landlord refuses to reimburse you. Now, the Ramah clarifies that although a vacating tenant is forbidden to take his mezuzos with him he does have the right to demand that the landlord reimburse him for them. But, if the landlord refuses to do so, he is still forbidden to take them with him and must leave them behind.
