Q. A group of women students are renting an apartment together. Can they place a Mezuza themselves and say a bracha?
A. Yeshuos Malko (H. Mezuza 5: 10) maintains that even though women are liable to comply with this mitzva, they are not permitted to place the Mezuza as they are also not permitted to write it.
However, many Poskim disagree (Birkei Yosef, Eretz Zvi 15, Da'as Cohen 169, Yabia Omer 3: 18, Miyam Halocho 1: 13 and others).
Horav Shlomo Miller's Shlit'a opinion is similar.
