Mezuzah: Difference between revisions

#If the big room is an entrance into the small room (picture #1), if that entrance is created by the ends of walls and not doorposts, some poskim hold that the entrance is exempt from mezuzah.<ref>Chovat Hadar 7:7. Avnei Yishpa 3:95:1 quotes Rav Elyashiv as holding that it is exempt from a mezuzah. His reasoning is that the ends of the walls of the big room aren't doorposts for the small room since they are really one wall with a break. The end of a wall serving as a doorpost is only if there's no continuation of that wall on the opposite side continuing the wall.</ref> Some disagree.<ref>Chut Shani (Mezuzah p. 107) holds that it is obligated to put up a mezuzah with a bracha since from the inside of the big room it is recognizable as a doorway. Pitchei Mezuzot p. 154-5 holds that it requires a mezuzah according to the Rosh since it is the end of a wall and can be seen as a doorpost. According to him, it doesn't matter if it is from the small room to the big room or otherwise. Pitchei Shaarim 287:1:12 p. 215 agrees.</ref> To avoid the dispute one should put up a mezuzah without a bracha.<ref>[https://www.hebrewbooks.org/pdfpager.aspx?req=49139&pgnum=122 Keviyut Mezuzah Khilchata 9:11] writes that this case of a big room into a small room is a big dispute and unresolved one should put up a mezuzah there without a bracha. Madanei Asher (Mezuzah 30:3 p. 88) agrees.</ref>

#If the small room is an entrance into the big room (picture #2)<ref>Another picture of this case can be found [https://www.hebrewbooks.org/pdfpager.aspx?req=49139&pgnum=430 in Keviyut Mezuzah Khilchata p. 430].</ref> that entrance is obligated even if the doorpost is created by the ends of the walls.<ref>Chovat Hadar 7:7 writes that if there's a small room which opens into a big room if the big room is an entrance to the small room it is considered exempt. If the small room is an entrance to the big room it is obligated since the walls of the big room serve as the mezuzot for the entrance going into the big room. Chut Shani (Mezuzah p. 107) agrees that it is obligated to put up a mezuzah according to the Rosh that ends of walls count as doorposts. Pitchei Shaarim 287:1:12 p. 215 agrees.</ref> Other argue that it is exempt from having a mezuzah.<ref>Avnei Yishpa 3:95:1 says that it is clearly exempt since there are no noticeable doorposts from inside the small room. [https://www.hebrewbooks.org/pdfpager.aspx?req=49139&pgnum=122 Keviyut Mezuzah Khilchata 9:11] writes that this case of a small room into a big room is an unresolved question and should have a mezuzah without a bracha. Madanei Asher (Mezuzah 30:3 p. 88) agrees. Madenei Asher cites Maaseh Nissim ch. 24 who says that in the Ben Ish Chai's house he didn't have a mezuzah on a room that was just three walls and the fourth was completely open  (e.g. [https://he.wikipedia.org/wiki/%D7%9C%D7%99%D7%95%D7%95%D7%90%D7%9F#/media/%D7%A7%D7%95%D7%91%D7%A5:Liwan-He.png]), though he is puzzled about why he didn't put up a mezuzah in light of Ben Ish Chai (Ki Tavo n. 13).</ref>
