משנה תורה הִלְכּוֹת מְזוּזָה ו:א
עֲשָׂרָה תְּנָאִין יֵשׁ בַּבַּיִת, וְאַחַר כָּךְ יִתְחַיַּב הַדָּר בּוֹ לַעֲשׂוֹת לוֹ מְזוּזָה, וְאִם חָסֵר תְּנָאי אֶחָד מֵהֶן, פָּטוּר מִן הַמְּזוּזָה; וְאֵלּוּ הֶן: שֶׁיִּהְיֶה בּוֹ אַרְבַּע אַמּוֹת עַל אַרְבַּע אַמּוֹת אוֹ יָתֵר, וְשֶׁיִּהְיֶה לוֹ שְׁתֵּי מְזוּזוֹת, וְיִהְיֶה לוֹ מַשְׁקוֹף, וְתִהְיֶה לוֹ תַּקְרָה, וְיִהְיוּ לוֹ דְּלָתוֹת, וְיִהְיֶה גֹּבַהּ הַשַּׁעַר עֲשָׂרָה טְפָחִים אוֹ יָתֵר, וְיִהְיֶה בֵּית חֹל, וְיִהְיֶה עָשׂוּי לְדִירַת אָדָם, וְעָשׂוּי לְדִירַת כָּבוֹד, וְעָשׂוּי לְדִירַת קְבָע.
There are 10 conditions that a house must meet in order for the resident to be obligated to put up a mezuzah… It must be at least 4 amot (1 amah = 18 inches) by 4 amot. It must have 2 doorposts. It must have a lintel (horizontal structure spanning the opening). It must have a roof. It must have doors. The gate must be 10 t’fachim (1 tefach = 3 inches) or higher. It must be for ordinary purposes. It must be made as a place for people to live. It must be made as an honorable place. It must be made as a permanent place (translation by Rabbi Jill Jacobs).
