General Mezuzah mounting questions

Obligation by location

QUESTION:
Which entrances are exempt from mezuzahs?

ANSWER:
• Bathrooms and shower rooms.
• Storage rooms that are less than four cubits long and four cubits wide (approximately 61/2 ft. x 6 1/2 ft. or 37 square foot).
• A room with an area of sixteen square cubits, that has one side less than a cubit long. (i.e. 1’x 40’)
• Any door that’s used only as an Emergency exit.

A small room leading into a larger room (i.e. a foyer) requires a mezuzah. There are other small rooms that may require mezuzahs as well, therefore an observant Rabbi should be consulted to determine whether a mezuzah is required.

QUESTION:
Do I require mezuzahs if my home is being renovated or painted?

ANSWER:
Mezuzahs do not need to be mounted if this will interfere with the construction. However, a practical suggestion would be to use mounting tape to facilitate affixing or removing mezuzahs during construction.

A WORD OF CAUTION:
If you are constructing a door in an archway that has a mezuzah of its own, you must remove the mezuzah before installing the door. After the door is properly installed, you should remount the Mezuzah with a blessing. Never mount a mezuzah on a doorpost before the doorpost is installed.

QUESTION:
What if I never use that door?
What if the door is blocked by furniture?

ANSWER:
According to the majority of opinions, only unused doors that are sealed closed (doors actually nailed to the door frame) are exempt from mezuzahs. Entrances blocked by furniture or doors that are usually kept locked require mezuzahs.

QUESTION:
Do garage doors, boiler rooms, attics, outdoor sheds, or crawl spaces require mezuzahs?

ANSWER:
According to many rabbinical authorities, mezuzahs are required on all garage doors (including garage overhead doors), boiler rooms, outdoor sheds, and even crawl spaces, provided that they comply with the required measurements (approximately 37 square feet).

At the entrance to a crawl space, the doorposts themselves must be at least 10 handbreadths high (approximately 32 inches) and four handbreadths wide.

An attic also requires a mezuzah unless it has a horizontal doorway. (See Illustration 4/5)

QUESTION:
How do I measure 37 sq. foot in a boiler room?

ANSWER:
The measurement of 37 square feet should NOT include the space being used by permanently mounted appliances or fixtures (e.g. boilers, cabinets).

QUESTION:
Are Mezuzahs required on doors where refuse is stored?

ANSWER:
No. The same will apply for any room with a strong odor.

QUESTION:
Am I required to affix a Mezuzah on a door leading to an empty room which is not being used at all?

ANSWER:
Some authorities exempt the placing of a Mezuzah on such rooms.

QUESTION:
What about balconies or sun porches (from upper floors)?

ANSWER:
Balconies and porches require mezuzahs. There is a difference of opinion whether the mezuzah is to be placed on the right side of the door leading into the house, or on the right side of the door leading onto the porch.

QUESTION:
I live in a house with several sliding doors leading into the back yard. Should I affix their mezuzahs the identical way on all of the sliding doors?

ANSWER:
No. It depends if the sliding door slides from right to left or from left to right.

If it slides from right to left (when facing the inside of your home) then the mezuzah is placed on the extreme right side as you enter the home.

If however the door slides from left to right (when facing the inside of your home) then you must affix the mezuzah on the right side of the doorpost, not on the extreme right side of the doorframe.

QUESTION:
Do I need a mezuzah at my workplace?

ANSWER:
Yes. In addition to private places of residence, mezuzahs must also be placed in businesses and stores without a blessing. If you’re working for a non-Jew and you are renting space from him, a mezuzah should be affixed on your office door without a blessing. Some authorities add, that the obligation is only if one eats there as well. However, if you are not renting the space, and there is always a possibility that your office space could be relocated without notice, then you would be exempt from affixing a mezuzah.

QUESTION:
Am I obligated to affix a mezuzah on a room that is shared with another person?

ANSWER:
The opinions vary when sharing with a non-Jew. It is therefore recommended to put up a Mezuzah, provided the non-Jew will not be offended and will allow you to put it up. If sharing with a Jew, it is an obligation upon each partner/tenant to affix that Mezuzah.

QUESTION:
Is a landlord obligated to put mezuzahs in a building where not all the tenants are Jewish?

ANSWER:
There’s no obligation on the rented apartments but there is an obligation on all the common areas as well as the vacant apartments that are used by the landlord.

QUESTION:
I have a live-in maid. Am I required to put a mezuzah on her door?

ANSWER:
Yes, providing that upon your discretion, her room may be changed to another location in the house at any given time.

QUESTION:
Does a washing room (outside a lavatory) require a Mezuzah?

ANSWER:
A mezuzah is required providing that the washing room is 37 sq. foot and that there is another door separating the lavatory from the washing are
