Siman 105: Things forbidden on Chol HaMoed because of exertion
Presented here for study, not as a practical ruling. The Shulchan Aruch rules by Sephardi custom, the Rema's glosses by Ashkenazi custom, and the Kitzur follows Ashkenazi custom. For a practical question, ask your rabbi.
א אָסוּר לְהַסִּיעַ וְלִשָּׂא מִטַּלְטְלָיו וּכְלֵי בֵּיתוֹ בְּחֹל הַמּוֹעֵד מִדִּירָה שֶׁבֶּחָצֵר זוֹ לְדִירָה שֶׁבֶּחָצֵר אַחֶרֶת, אֲפִלּוּ מִדִּירָה כְעוּרָה לְדִירָה נָאָה. אֲבָל מִבַּיִת לְבַיִת בֶּחָצֵר אַחַת, מֻתָּר. וְכֵן אִם שְׁתֵּי הַחֲצֵרוֹת סְמוּכוֹת וְיֵשׁ פֶּתַח בֵּינֵיהֶן, מֻתָּר לְהוֹצִיא הַחֲפָצִים דֶּרֶךְ שָׁם. וּבִמְקוֹם פְּסֵידָא, מֻתָּר אֲפִלּוּ מֵעִיר לְעִיר. וְכֵן מִדִּירָה שֶׁאֵינָהּ שֶׁלּוֹ לְדִירָה שֶׁהִיא שֶׁלּוֹ, מֻתָּר מִשּׁוּם שִׂמְחַת יוֹם טוֹב, שֶׁשִּׂמְחָה הִיא לוֹ לָדוּר בְּדִירָה שֶׁהִיא שֶׁלּוֹ (תקל"ה).
1 It is forbidden to move and carry movable belongings and household utensils on Chol Hamoed, from an apartment in one courtyard to an apartment in another courtyard, even from an unattractive apartment to a nice one. But to move these items from one house to another in the same courtyard, is permitted. Similarly, if the two courtyards are adjacent to each other, and there is a door between them, it is permitted to take things out through that door. However, if you would otherwise incur a loss, you are permitted to move these articles even from one city to another. Moving from a house that doesn't belong to you to your own house, is permitted, for this is considered rejoicing on Yom Tov, because it is a joy to live in your own home.
ב אִם צָרִיךְ לְהַכְנִיס פֵּרוֹתָיו אוֹ שְׁאָר סְחוֹרָה מִפְּנֵי שֶׁהוּא יָרֵא מִפְּנֵי גַּנָּבִים אוֹ מִשְּׁאָר הֶפְסֵד, כָּל מַה שֶּׁאֶפְשָׁר לַעֲשׂוֹת בְּצִנְעָה יַעֲשֶׂה. וְאִם אִי אֶפְשָׁר לַעֲשׂוֹת בְּצִנְעָא, מֻתָּר לַעֲשׂוֹת אֲפִלּוּ בְּפַרְהֶסְיָא.
2 If you must take in fruit, or other merchandise because you fear it will be stolen, or damaged, it should be done in a secluded manner if possible. If you cannot do it in a secluded manner, you are permitted to do it openly.
