A storage room smaller than 4×4 cubits — does it need a mezuzah?
The minimum size is 4×4 cubits (about 6×6 feet). Below that, the space doesn't qualify as a "room" for mezuzah purposes.
Question 2
Does a synagogue require a mezuzah?
A synagogue without an attached dwelling: exempt. The space must function as a residence, not just a gathering place. If there's a caretaker's dwelling, the gate requires a mezuzah.
Question 3
Does a sukkah require a mezuzah?
The sukkah is explicitly temporary — built for the holiday and dismantled. Mezuzah requires permanent, year-round dwelling.
Question 4
Do city gates require mezuzot?
The obligation extends beyond individual rooms to communal entrances: city gates, courtyard gates, and alley entrances all need mezuzot.
Question 5
How many conditions must a room meet to require a mezuzah?
The Rambam lists ten specific conditions. A room must meet all ten — size, doorway components, roof, height, permanence, dignity, and human habitation.
