Mishnah 1א׳

הַמּוֹכֵר אֶת הַבַּיִת, לֹא מָכַר הַיָּצִיעַ, וְאַף עַל פִּי שֶׁהִיא פְתוּחָה לְתוֹכוֹ, וְלֹא אֶת הַחֶדֶר שֶׁלִּפְנִים מִמֶּנּוּ, וְלֹא אֶת הַגַּג בִּזְמַן שֶׁיֶּשׁ לוֹ מַעֲקֶה גָבוֹהַּ עֲשָׂרָה טְפָחִים. רַבִּי יְהוּדָה אוֹמֵר, אִם יֶשׁ לוֹ צוּרַת פֶּתַח, אַף עַל פִּי שֶׁאֵינוֹ גָבוֹהַּ עֲשָׂרָה טְפָחִים, אֵינוֹ מָכוּר:

One who sold a house has not sold its annex, even though it opens into the house, nor the room that further in [to the property than the house], nor the roof, if it has a railing more than ten hand-breadths high. Rabbi Yehudah says: If [the entrance to the roof] has the form of a door, even if [the railing] is not ten hand-breadths high, it is not sold.

Mishnah 2ב׳

לֹא אֶת הַבּוֹר, וְלֹא אֶת הַדּוּת, אַף עַל פִּי שֶׁכָּתַב לוֹ עֻמְקָא וְרוּמָא. וְצָרִיךְ לִקַּח לוֹ דֶרֶךְ, דִּבְרֵי רַבִּי עֲקִיבָא. וַחֲכָמִים אוֹמְרִים, אֵינוֹ צָרִיךְ לִקַּח לוֹ דָרֶךְ. וּמוֹדֶה רַבִּי עֲקִיבָא, בִּזְמַן שֶׁאָמַר לוֹ חוּץ מֵאֵלּוּ, שֶׁאֵינוֹ צָרִיךְ לִקַּח לוֹ דָרֶךְ. מְכָרָן לְאַחֵר, רַבִּי עֲקִיבָא אוֹמֵר, אֵינוֹ צָרִיך לִקַּח לוֹ דֶרֶךְ. וַחֲכָמִים אוֹמְרִים, צָרִיךְ לִקַּח לוֹ דָרֶךְ:

Nor [has he sold] the cistern or the cellar, even though he had written in the deed of sale, “The depth and height." And [the seller] must buy himself a path [from the new owner to reach his cellar or cistern] - the words of Rabbi Akiva. But the Sages say: He need not buy himself a path. And Rabbi Akiva agrees that if he had said to him, “Excepting [the cistern or cellar],” that he need not buy himself a path. If he sold [the cellar or cistern] to another, Rabbi Akiva says: He need not buy himself a path. But the Sages say: He must buy himself a path.
