Do elevators require a Mezuzah?

Q. Do elevators require a Mezuzah?

A. There is a debate among authorities as to whether elevators require a Mezuzah. Most authorities feel that since the elevator is not stationary it is exempt from a Mezuzah. Thus an elevator or a door leading into an elevator does not require a Mezuzah.

The authorities that do require a Mezuzah on elevator doorways that are stationary write that it should be affixed on the right side as one enters the elevator on the bottom floor. On the other floors it should be affixed on the right side as one exits the elevator and enters the hallway.
