SECTION 636 Laws Relating to an Old Sukkah. (1–3)

סימן תרלו דִּין סֻכָּה יְשָׁנָה וּבוֹ ג' סְעִיפִים:

1 An old sukkah — i.e., one that was made more than 30 days before Sukkos — is valid, provided1 something new was done to it for the sake of the festival.2 If it was constructed for the sake of the festival,3 even at the beginning of the year,4 nothing new need be done to it.5

א סֻכָּה יְשָׁנָה,א דְּהַיְנוּ שֶׁעֲשָׂאָהּ קֹדֶם שְׁלֹשִׁים יוֹם שֶׁלִּפְנֵי הַחַגב – כְּשֵׁרָה,1 וּבִלְבַד שֶׁיְּחַדֵּשׁ בָּהּ לְשֵׁם הַחַג.ג,2 וְאִם עֲשָׂאָהּ לְשֵׁם חַג3 אֲפִלּוּ מִתְּחִלַּת הַשָּׁנָה4 – אֵין צָרִיךְ לְחַדֵּשׁ בָּהּ דָּבָר:ד,5

Alter Rebbe's Shulchan Aruch (Kehot Publication Society)

The new layout – with the original text and the facing translation – provides a unique user-friendly approach to studying the Alter Rebbe’s work. An inclusive commentary provides insightful explanations and guidelines for actual practice.

2 This new activity must involve the s’chach itself, i.e., some new s’chach must be put in place for the purpose of the festival. For this, even a handbreadth by a handbreadth is sufficient.6 Alternatively, if the new s’chach extends along the entire length or across the entire width of the sukkah, even [a strip of] the slightest width is sufficient.

All of the above applies to the s’chach. With regard to the walls, [the sukkah is valid] even if they were made at the beginning of the year explicitly for a purpose other than the festival. Nothing new need be done to them.

ב חִדּוּשׁ זֶה שֶׁאָמַרְנוּ – צָרִיךְ שֶׁיְּהֵא בְּגוּף הַסְּכָךְ,ה דְּהַיְנוּ שֶׁיַּנִּיחַ סְכָךְ חָדָשׁ לְשֵׁם הַחַג, וַאֲפִלּוּ אֵין בַּסְּכָךְ הַמְחֻדָּשׁ אֶלָּא טֶפַחו עַל טֶפַחז מְרֻבָּעח – דַּי בְּכָךְ.6 וְאִם אֹרֶךְ הַחִדּוּשׁ הוּא הוֹלֵךְ עַל פְּנֵי כָּל אֹרֶךְ אוֹ לְרֹחַב הַסֻּכָּה, אֲפִלּוּ אֵין בְּרָחְבּוֹ אֶלָּא כָּל שֶׁהוּא – דַּי בְּכָךְ.ט

וְכָל זֶה בַּסְּכָךְ, אֲבָל בַּדְּפָנוֹתי אֲפִלּוּ עֲשָׂאָן מִתְּחִלַּת הַשָּׁנָה בְּבֵרוּר שֶׁלֹּא לְשֵׁם הַחַג – אֵינוֹ צָרִיךְ לְחַדֵּשׁ בָּהֶם דָּבָר:

3 [The following laws apply with regard to] a potter [whose workplace is comprised] of two [adjoining] sukkos, one of which gives access to the other, and both of which were constructed for shade.7 He fashions his pots in the inner [sukkah] and sells them in the outer [sukkah].

Though the inner sukkah was built for shade, he does not fulfill [the obligation to dwell] in the sukkah with it, because it serves as his dwelling throughout the year. Since he eats, sleeps, and performs most of his activities there, it would not be evident [during the festival] that he is now doing these things for the sake of the mitzvah. He may, however, fulfill his obligation using the outer [sukkah], for he does not dwell in it throughout the year.8

Moreover, even the inner [sukkah] is valid if he raises the s’chach and then puts it back for the sake [of the mitzvah] of sukkah,9 for even the roof of a house can be validated for s’chach through such an action, as explained in sec. 631.10

ג יוֹצֵר כְּלִי חֶרֶס שֶׁיֵּשׁ לוֹ שְׁתֵּי סֻכּוֹת זוֹ לִפְנִים מִזּוֹיא וּשְׁתֵּיהֶן עֲשׂוּיוֹת לְצֵליב,7 וְעוֹשֶׂה קְדֵרוֹתָיו בַּפְּנִימִית וּמוֹכְרָם בַּחִיצוֹנָהיג – הַפְּנִימִית אֵינוֹ יוֹצֵא בָּהּ יְדֵי סֻכָּה,יד אַף עַל פִּי שֶׁהִיא עֲשׂוּיָה לְצֵל, מִכָּל מָקוֹם כֵּיוָן שֶׁהִיא דִּירָתוֹ כָּל הַשָּׁנָה שֶׁהוּא אוֹכֶל וְיָשֵׁן בָּהּ וְעוֹשֶׂה בָּהּ רֹב תַּשְׁמִישׁוֹ – אֵין נִכָּר שֶׁהוּא דָּר בָּהּ עַתָּה לְשֵׁם מִצְוָה,טו אֲבָל הַחִיצוֹנָה יוֹצֵא בָּהּ יְדֵי סֻכָּה,טז שֶׁהֲרֵי אֵינוֹ דָּר בָּהּ כָּל הַשָּׁנָה,יז,8 וַאֲפִלּוּ הַפְּנִימִית אִם מַגְבִּיהַּ אֶת הַסְּכָךְ וְחוֹזֵר וּמַנִּיחוֹ לְשֵׁם סֻכָּה – כְּשֵׁרָה,יח,9 שֶׁהֲרֵי אֲפִלּוּ תִּקְרַת הַבַּיִת מִתְכַּשֶּׁרֶת לְסִכּוּךְ עַל יְדֵי מַעֲשֶׂה זוֹ כְּמוֹ שֶׁנִּתְבָּאֵר בְּסִימָן תרל"א:יט,10
