Do all Mezuzot require a Bracha (blessing), when affixing to the doorpost?
Not all Mezuzot require a Bracha. A room whose dimension is more than 36 sq. feet, however one dimension is less than 6 feet (for example 8 x 5), the Mezuzah is affixed without a Bracha. For a room used as a store/office or for storage purposes, the Mezuzah is affixed without a Bracha. Walk-in-closets (that require Mezuzot) and rooms without doors all require Mezuzot without a Bracha.
